Description

Turbocompressor and method for driving thereof
Technical field
The present invention relates to make fixed turbine and revolution turbine to nibble to be incorporated in and form compression volume between both sides, utilize circular orbit motion to make compression volume for example when dwindling volume, move the turbocompressor and the method for driving thereof of the suction, compression and the discharge that repeat fluid to central part from peripheral part because of the revolution turbine.
Background technique
This turbocompressor in the past generally has structure shown in Figure 14.In this structure, make fixed turbine 1 and revolution turbine 2 nibble to be incorporated in and be formed with a plurality of compression volumes 3 between both sides.Revolution turbine 2 prevent with rotation member 4 prevent under the state of rotation through floating bearing 7 driven by the eccentric part 9 of crankshaft 8 and relative fixed turbine 1 to carry out the circular orbit motion be rotation motion.Owing to utilize the rotation motion of this revolution turbine 2 to make compression volume 3 dwindle volume to the central part of scrollwork while moving, after sucking refrigerant gas and compression, discharge to the inner space 13 of seal container 12 by exhaust port 11 from suction port from outer circumferential side.Here, this turbocompressor is that main structural element constitutes compression mechanical part 14 with above-mentioned fixed turbine 1 and revolution turbine 2.
The driving mechanism of above-mentioned compressor structure portion 14 comprises the motor that is made of the stator 18 of the inboard of being fixed in seal container 12 and the rotor 19 that supports with freely rotating in the inboard of this stator 18.Be combined with above-mentioned crankshaft 8 with breakthrough status in motor 19, the upper end part of crankshaft 8 is bearing on the main bearing member 21 freely by bearing 20 rotations.On the tip portion of crankshaft 8, be provided with the above-mentioned eccentric part 9 that correspondingly thereto carries out eccentric motion.Volume type pump 22 is established in the underpart of crankshaft 8, and is bearing in freely on the support member 24 that is fixed in the seal container 12 by ball bearing 23 rotations.
Store that liquid supply passage 27 that the driving of wet goods lubricant oil (not shown) by volume type pump 22 in the liquid reservoir 25 of the underpart of seal container 12 form vertically from the central part at crankshaft 8 is up inhaled and turning axle 7 is lubricated and cools off, and after the circulation of bearing 20 places, return liquid reservoir 25 through the liquid reservoir 28 and the storage liquid space 29 of eccentric part 9 tops, carry out recirculation by same path later.On the other hand, the part of the lubricant oil of supplying with to liquid reservoir 28 is reduced pressure by restriction 31 on one side through the slotted hole 30 of the inside that is located at revolution turbine 2 and supplies with to back pressure chamber 32 on one side.Back pressure chamber 32 be with the recess 34 of revolution runner plate 33, the main bearing member 21 of revolution turbine 2, fixed turbine 1 go up facial 55 and the space that surrounds of sealing component 38 and the back that is positioned at revolution turbine 2, utilize hydrodynamic pressure will turn round turbine 22 has not effect from the back pressure of drawing back from fixed turbine 1 to fixed turbine 1 thruster pressure.In addition, sealing component 38 carries out as the storage liquid space 29 of the high-voltage section of keeping head pressure and the sealing between the back pressure chamber 32.
Again, the lubricant oil of supplying with to above-mentioned back pressure chamber 32 prevents that to above-mentioned rotation member 4 is lubricated.This back pressure chamber 32 must have the back pressure that revolution turbine 2 is not drawn back from fixed turbine 1 all the time.But when this back pressure became surplus, revolution turbine 2 to fixed turbine 1 pushing, was caused the inordinate wear of turbine slide part and input to increase by powerfully.Therefore, back pressure must remain necessarily.Therefore, though above-mentioned back pressure is rising to the occasion that is higher than setting value along with lubricant oil accumulating and rise in back pressure chamber 32, pressure adjustmenting mechanism 39 actions guide to compression volume 3 with the lubricant oil in the back pressure chamber 32 from sucking path 40.Promptly emit from back pressure chamber 32.Thus, above-mentioned back pressure can be maintained at certain value all the time.Be directed and be discarded to lubricant oil in the compression volume 3 and have the sealing function of leakage of refrigerant gas in preventing to compress etc. and the function that the surface of contact of fixed turbine 1 and revolution turbine 2 is lubricated.
As shown in figure 15, above-mentioned restriction 31 is the pin shape members that have screw section 31a on a part of outer circumferential face, is formed with the pore 31b that is used to produce restriction effect at central part.Thus, the restriction effect decompression of the lubricant oil of the liquid reservoir 28 of Figure 14 when utilizing flow to the pore 31b by restriction 31 to carry out throttling is after gross porosity 13c, and only appropriate amount is supplied to back pressure chamber 32.The appropriate amount of this lubricant oil is adjusted by the diameter of setting pore 31b.
In addition, has as shown in figure 16 structure (with reference to Japanese patent laid-open 7-77182 communique) as in the past another kind of turbocompressor.It is that certain value is opened valve when above and lubricated differential pressure fuel system in the compression mechanical part 14 is emitted and supplied with to the surplus input to the suction side of compression mechanical part 14 that this turbocompressor adopts in the back pressure chamber back pressure.That is to say, press the pressure of chamber 42 and the differential pressure of head pressure that the lubricant oil 41 in the liquid reservoir 25 of the bottom of seal container 12 is supplied to main bearing member 21, floating bearing 7 and other sliding position in the middle of utilizing.Remain the intermediate pressure of suction pressure and head pressure on the middle platen of pressing chamber 42 to be located at revolution turbine 2 by 2 intermediate holes (not shown) that will be communicated with compression volume 3.Utilize above-mentioned pressure difference works lubricant oil 41 through the liquid supply passage 27 of crankshaft 8, as restriction fuel feeding slot part 43 and be supplied to floating bearing 7 and main bearing member 21.In addition, entering the middle lubricant oil 41 of chamber 42 of pressing presses hole and platen peripheral part to emit with the space of refrigerant gas in seal container 12 from exhaust port 11 to compression volume 3 supply backs in the middle of revolution turbine 2.
As Figure 17 and shown in Figure 180, the suction path 44 of compression mechanical part 14 is provided with its running and shuts down corresponding and one-way valve 45 that open and close.When compressor operation, enter from the refrigerant gas of outer loop and to suck path 44, one-way valve 45 utilizes above-mentioned gas inhalating pressure to be pushed into the position of Figure 18 down from the position of Figure 17, forms the space that is communicated with the compression volume 3 of Figure 16 above it.Thus, suck gas and be sucked into compression volume 3 from above-mentioned space.In addition, compressed refrigerant is expelled to the inner space of seal container 12 from the exhaust port 11 of Figure 16, and these pressurized gas that are discharged from are supplied to the lower space of holding motor 17 etc. from the upper space of seal container 12 by breach on the peripheral part of being located at compression mechanical part or intercommunicating pore.At this moment, the stator 18 of refrigerant gas cool motors 17, again the space by motor 17 grades from exhaust port 11 become vaporific and with the lubricating oil separation that is discharged from, the refrigerant gas of high pressure is back to outer loop from drain passageway 47.
When the running of compressor stops, utilization is from compression volume 3, seal container 12 and drain passageway 47 are back to the refrigerant gas of high pressure midway of outer loop from suck path 44 power that flows backwards to the leading portion side and the spring 48 that is arranged at the hypomere of one-way valve 45, one-way valve 45 is pushed back to the position of Figure 17 from the position of Figure 18, to flow backwards to prevent refrigeration agent with the path locking of suction side with the end face of sealing collar 49 and the plane of one-way valve 45, and prevent that the lubricant oil 41 of compressor bottom from passing through the liquid supply passage 27 of conduct to the crankshaft 8 of the fuel supply path of slide part, floating bearing 7, main bearing member 21, the middle chamber 42 of pressing, middle hole and the compression volumes 3 etc. of pressing are taken out of to the outside of compressor.
Yet, the turbocompressor of Figure 14 is to be purpose to improve the restriction effect that is produced by restriction 31, and when with the reduced of pore 13 and when the length of pore 31 is increased,, cause the performance of compressor to reduce owing to sneak into easy inaccessible pore 31b such as dust in the lubricant oil.And when pore 31b being set for the length of little diameter and length, processing becomes difficulty and manufacture cost is increased.Again, in above-mentioned compressor owing to use volume type pump 22 to carry out the supply of the lubricant oil of liquid reservoir 25, so the increase during because of number of spare parts and rigger makes cost up.
In addition, in the turbocompressor of Figure 16, though owing to not using positive displacement pump to have the advantage that cost simple in structure reduces, but to obtain high reliability is that purpose is established only one-way valve 45, the leakage at the sealing surface place in this one-way valve gas more for a long time produces refluence, at this moment lubricant oil is by lubricant oil 41 deficiencies of taking out of to the outside and being used to lubricate, so the problem that exists reliability to reduce.Again, in above-mentioned compressor, one-way valve 45 becomes the suction resistance of gas when turning round usually, so the problem that exists performance to reduce.
The present invention in view of the above problems, its purpose is to provide a kind of and makes the structure simple, that cost reduces and also bring into play high efficiency and the turbocompressor of high reliability and method for driving thereof.

Concrete example
Followingly several preferable examples of the present invention are described with reference to Fig. 1-Figure 13.Several examples all are the application examples that expression is used for the enclosed turbocompressor of air-conditioning, refrigerating machine.Therefore, the fluid of use is a refrigeration agent, below promptly describes as refrigeration agent.But the invention is not restricted to this.Among the figure, different for turbocompressor and Figure 14 of clear and definite these examples, turbocompressor in the past shown in Figure 16 are all adopted identical label for member identical with Figure 14 and Figure 16 or that function is suitable.
At first the method for driving of the turbocompressor of the present invention's one example is described with reference to Fig. 1-Figure 13.As Fig. 1, Fig. 5, Fig. 6, Fig. 8, Figure 11, shown in Figure 13, by erectting fixed turbine 1 that blade 50,51 is arranged and the engagement formation compression volume 3 that turns round turbine 2 respectively and constitute compression mechanical part 14 from demarcating runner plate 37 and revolution runner plate 33 admittedly, utilization make above-mentioned revolution turbine 2 relative to said fixing turbine 1 carry out circular orbit when motion above-mentioned compression volume 3 for example along with from the variation of moving generation volume of outer circumferential side to central part, carry out the suction of fluid by suction port 10, compression and the discharge by exhaust port 11.
Simultaneously, by with in the crankshaft 8 of an example of a distolateral driving as the axle of above-mentioned revolution turbine 2, and will be supplied to the lubricant oil supply system 102 above-mentioned one distolateral compression mechanical part 14 as the lubricant oil 101 of the wet goods of an example that stores the liquid there and the various slide parts of compression mechanical part 14 will be lubricated from its another distolateral liquid reservoir 25.Again, carry out this lubricant oil 101 after lubricated through or be supplied to the back of revolution turbine 2 without the storage liquid space 29 that keeps head pressure, the back pressure that revolution turbine 2 is pressed to fixed turbine 1 thruster works and realizes turning round the stable revolution of turbine 2 and prevent and throw off from fixed turbine 1.
In the drive condition of this turbocompressor, especially from above-mentioned liquid reservoir 25 by crankshaft 8 and through storage liquid space 29 to as for example back pressure chamber 32 that back pressure is acted on the back pressure zone of action on the revolution turbine 2.Because along be communicated with the rotating intermittence of the crankshaft 8 at 2 places in feed paths 100 that stated and all lubricant oil 101 of not stating, or owing to along with in the back pressure of the surplus that is used to make back pressure chamber 32, promptly emit lubricant oil 101 and adjust and be communicated with intermittence of rotation of crankshaft 8 at 1 place that emits path 103 of the lubricant oil 101 that the pressure adjustmenting mechanism 39 of back pressure works, the delivery volume by adjusting 101 pairs of above-mentioned back pressure chambers 32 of lubricant oil or/and discharging amount when making above-mentioned back pressure remain on predetermined range, drive.
Like this, in compression mechanical part 14 with common suction, compression, discharge also together, crankshaft 8 by side drive at one end revolution turbine 2 also will store lubricant oil 101 in another distolateral liquid reservoir 25 and supply with compression mechanical parts 14 and be lubricated, simultaneously owing to make lubricant oil 101 after lubricated supply with and have the back pressure effect that revolution turbine 2 is pressed to fixed turbine 1 thruster to the back pressure chamber 32 at the back that is positioned at revolution turbine 2, so revolution turbine 2 smoothly and is stably turned round drive and from fixed turbine 1 disengagement through the storage liquid space 29 that is maintained head pressure.
Especially, adjust back pressure so that play a side's of the delivery volume of lubricant oil 101 of above-mentioned back pressure effect and discharging amount adjustment, or the adjustment that utilizes both sides is more easily adjusted back pressure, simultaneously to be communicated with at intermittence to 2 places of the feed path 100 of back pressure chamber 32, or be communicated with at the rotating intermittence along with crankshaft 8 at 1 place of above-mentioned feed path 100 at the connected sum at intermittence of 1 of emitting path 103 from back pressure chamber 32, by utilizing at above-mentioned feed path 100 or/and emit the liquid for intermittence of back pressure chamber 32 at 2 places in path 103 and supply with or/and the combination of emitting, guarantee along with the rotating correct cycle of crankshaft 8 and regularly for the meticulousr trace adjustment of the delivery volume of the liquid of back pressure chamber 32 or discharging amount, need not that every machine suitably be set and be kept to special driving mechanism and control mechanism just can or/and every running and the back pressure that needs, can improve the Performance And Reliability of turbocompressor.
For use feed path 100 to carry out at least to the supply of the lubricant oil 101 of above-mentioned back pressure chamber 32 by crankshaft 8 and revolution turbine 2, to the supply of the lubricant oil 101 at above-mentioned intermittence or emit and to utilize between the bearing support 52 and crankshaft 8 of above-mentioned liquid reservoir 25 places axles supporting crankshaft 8, compression mechanical part 14 sides of above-mentioned revolution turbine 2 and said fixing turbine 1 or axle supporting crankshaft 8 and between the either or both of the main bearing member 21 of support member one example of anti-fixed turbine 1 side bearing revolution turbine 2, the connection at intermittence of feed path 100 at least 1 place of portion of respectively relatively moving is carried out, if this method of employing then all can utilize the mechanism and the member that have been provided with to realize.
Again, be communicated with the intermittence to the feed path 100 between the either or both of revolution turbine 2 and fixed turbine 1 or main bearing member 21, all the time be formed at revolution turbine 2 communicatively with back pressure chamber 32 or/and the recess as shown in Figure 6 60 on the main bearing member 21 is communicated with when carrying out with the intermittence of turning round the feed path 100 between the turbine 2 if utilize, can utilize the size of recess 60 and shape often guarantee promptly to guarantee for emitting of the circular orbit motion of revolution turbine 2 with being communicated with of back pressure chamber 32 in, improve to set and be used to obtain and the aperture position of the feed path that is communicated with 100 at intermittence on the supply road 100 of turning round turbine 2 sides and the degrees of freedom when big or small.
Again, intermittently of feed path 100 be communicated with when carry out independently at per 2 ostiums 53,54 as shown in Figure 1 of the feed path 100 at least 1 place of the above-mentioned portion that relatively moves and intercommunicating pore 57,58 such a plurality of positions arranged side by side, the combination of the independently connected state by a plurality of positions arranged side by side, the supply condition to liquid carries out meticulousr inching easily.
Even the advantage of these connected states on recess 60 and a plurality of positions arranged side by side is applied to emitting path 103 and also obtaining same action effect of lubricant oil 101.
Turbocompressor to several examples of adopting above-mentioned method for driving describes below.As shown in Figure 1, the turbocompressor of the example of Fig. 1-shown in Figure 3 is, erect the fixed turbine 1 and 2 engagements of revolution turbine of blade 50,51 back shapes respectively from fixing runner plate 37 and revolution runner plate 33, between this fixed turbine 1 and the both sides that turn round turbine 2, be formed with a plurality of compression volumes 3.Revolution turbine 2 utilize European ring (Japanese: ォ Le ダ system リ Application ゲ) rotation of etc.ing prevents that the rotation of member 4 and machinery from preventing that machinery from waiting and preventing rotation, for example because the floating bearing 7 that invests self by embedding is installed on the eccentric part 9 of crankshaft 8 relative fixed turbine 1 to carry out that circular orbit moves be rotation motion.Above-mentioned compression volume 3 reduces volume on one side by for example moving to the central part of vortex from outer circumferential side on one side with the rotation motion of revolution turbine 2.Thus, in above-mentioned compressor, from suction port 10 refrigerant gas etc. is sucked and compression after, discharge to the inner space 13 of seal container 12 by exhaust port 11.Here, the turbocompressor of this example constitutes compression mechanical part 14 by above-mentioned fixed turbine 1 and revolution turbine 2 grades.
The driving mechanism of above-mentioned compressor structure portion 14 comprises the motor 17 that is made of the stator 18 of the inboard of being fixed in seal container 12 and the rotor 19 that supports with freely rotating in the inboard of this stator 18.Be connected with above-mentioned crankshaft 8 with breakthrough status on rotor 19, the upper end part of crankshaft 8 is supported on the main bearing member 21 with freely rotating by bearing 20.Tip portion at crankshaft 8 has the above-mentioned eccentric part 9 that correspondingly thereto carries out eccentric motion.Underpart in seal container 12 is fixed with support member 24, and the underpart of above-mentioned crankshaft 8 is bearing in the bearing support 52 that remains on the above-mentioned support member 24 with freely rotating.
Shown in Fig. 3 (a) and (b), bearing support 52 is for roughly cylindric, is formed with the ostium 53,54 of slotted hole shape along the circumferential direction side by side at 2 places that its heart direction and circumferencial direction all separate.In addition, the position of being supported by bearing support 52 on crankshaft 8 is equipped with the 1st and the 2nd the intercommunicating pore 57,58 that is communicated with liquid supply passage 27 along axis direction and ostium 53,54 2 relative places side by side.The the 1st and the 2nd intercommunicating pore 57,58 overlaps 1 time with ostium 53,54 in per 1 revolution of crankshaft 8, by intercommunicating pore 57,58 and the ostium 53,54 that overlaps fluid supply passage 27 is communicated with liquid reservoir 25.
The lubricant oil 101 that stores in the liquid reservoir 25 of the underpart of seal container 12 utilizes the inner space 13 of seal container 12 and the differential pressure of back pressure chamber 32, intercommunicating pore 57,58 by above-mentioned coincidence and ostium 53,54 and up inhale from liquid supply passage 27, after bearing 20 being lubricated and cooling off, floating bearing 7 is lubricated and cools off.Again, lubricant oil 101 is supplied with to back pressure chamber 32 by slotted hole 30 from the throttle orifice 59 that is formed on the revolution runner plate 33 after the liquid reservoir 28 above eccentric part 9 enters storage liquid space 29.Back pressure chamber 32 is spaces that the sealing component 38 by the face 55 of the recess 34 of revolution runner plate 33, the main bearing member 21 of revolution turbine 2, fixed turbine 1 and ring-type is surrounded, be positioned at the back of revolution turbine 2, utilize hydrodynamic pressure to have the back pressure effect that pushes to fixed turbine 1 and make and turn round turbine 2 from fixed turbine 1 disengagement.Again, sealing component 38 carries out as the sealing between 32 between the storage liquid space 29 of high-voltage section of keeping head pressure and back pressure chamber.
Again, 101 pairs of above-mentioned rotations of lubricant oil of supplying with to above-mentioned back pressure chamber 32 prevent that member 4 is lubricated.It is certain that the back pressure of this back pressure chamber 32 must keep frequently.But back pressure rose along with accumulating of lubricant oil in back pressure chamber 32.Therefore, rise to the occasion higher than setting value in this back pressure, pressure adjustmenting mechanism 39 actions, the lubricant oil 101 in the back pressure chamber 32 is just emitted to compression volume 3 from sucking path 40, thus, makes above-mentioned back pressure often be maintained at certain value.The leakage of the refrigerant gas during the lubricant oil of importing compression volume 3 prevents to compress etc., and lubricated fixed turbine 1 and the surface of contact that turns round turbine 2.
Relation when the throttle orifice 59 when seeing revolution runner plate 3 from the bottom surface and the action of sealing component 38 is shown in Fig. 2 (a)-(d).From the rotary positions (a)-(d) of per 90 degree of revolution turbine 2 as can be known, throttle orifice 59 is along with rotation motion leap sealing component 38 ground between storage liquid space 29 and back pressure chamber 32 of revolution turbine 2 carry out circular motion among Fig. 2.Therefore, because the as above above-mentioned relation of sealing component 38, be to and to store between liquid space 29 and the back pressure chamber 32 and carry out circular motion while cross sealing component 38 ground as the throttle orifice 59 of the part of feed path 100 to sealing between storage liquid space 29 and the back pressure chamber 32.Thus, slotted hole 30 from the peripheral part break-through of revolution turbine 2 to the corresponding interior all side half-way of storage liquid space 29, form the throttle orifice 59 that in this all side half-way arrive storage liquid space 29, both sides become hook-type continuously.But also can make in the scope that can in fact play same purpose any concrete structure.For example, though throttle orifice 59 direct opening on the back side of revolution runner plate 33 is not limited to this, also can be the slotted hole 30 from storage liquid space 29 to back pressure chamber 32 midway or the outer circumferential face of revolution runner plate 33 etc. to the position of back pressure chamber 32 direct openings.
Only at throttle orifice 59 during in the face of storage liquid space 29, storage liquid space 29 is communicated with off and on back pressure chamber 32, and the lubricant oil 101 of storage liquid space 29 passes through throttle orifice 59 and slotted hole 30 and to back pressure chamber 32 supplies.On the other hand, when throttle orifice 59 was faced sealing component 38 or back pressure chamber 32, above-mentioned connection was interdicted off and on, and lubricant oil is not supplied with to back pressure chamber 32.Therefore, if change throttle orifice 59 is faced the time scale of storage liquid space 29 in 1 revolution, just can adjust delivery volume to the lubricant oil 101 of back pressure chamber 32.
The diameter of the track of the setting by utilize forming the position when carrying out circular motion carries out various changes, the throttle orifice 59 of this example can be to adjusting in the face of the time scale of storage liquid space 29, do not make the unfavorable condition of the less and length of diameter when longer like that so can not produce in the past.
On the other hand, as shown in Figure 3, when overlapping with the ostium 53,54 of bearing support 52 off and on along with the revolution of crankshaft 8, the 1st and the 2nd intercommunicating pore 57,58 of crankshaft 8 is communicated with liquid reservoir 25.Here, be located at 2 intercommunicating pores 57,58 on the axial same line and ostium 53,54 Zhou Fangxiang length and form the value that the position can be set regulation one by one for, thus, can set lubricant oil inflow amount for suitable value to liquid supply passage 27.
Describe below with reference to the explanatory drawing of Fig. 4 relation 2 intercommunicating pores 57,58 of 2 ostiums 53,54 of the position of throttle orifice 59 and bearing support 52 and crankshaft 8.Now with throttle orifice 59 in the face of the state of storage liquid space 29 as connecting section intermittently, with throttle orifice 59 in the face of any state of sealing component 38 or back pressure chamber 32 as apolipsis interval intermittently.Again, the state that intercommunicating pore 57,58 is overlapped with ostium 53,54 is as connecting section intermittently, and the state that intercommunicating pore 57,58 and ostium 53,54 are not overlapped is as the apolipsis interval at intermittence.Crankshaft 8 between 1 refunding by the combination results that makes above-mentioned connecting section and apolipsis interval the 1st to the 3rd pattern shown in Figure 4.
In the 1st pattern, because liquid reservoir 25 is communicated with storage liquid space 29 by ostium the 53, the 1st intercommunicating pore 57, liquid supply passage 27 and throttle orifice 59, the lubricant oil utilization storage liquid space 29 of liquid reservoir 25 is supplied to the lubricant oil supply system with the differential pressure of back pressure chamber 32.In the 2nd pattern,, will comprise that liquid supply passage 27 is decompressed to identical with the back pressure of back pressure chamber 32 with the space pressure of the lubricant oil supply system of storage liquid space 29 because storage liquid space 29 is communicated with back pressure chamber 32.In this decompression process, in the lubricant oil supply system, dissolve in refrigeration agent foaming in lubricant oil, refrigerant gas and lubricant oil are supplied to back pressure chamber 32 by throttle orifice 59.
Below compressor is described from the state of operating condition when stopping.Under the situation after crankshaft 8 stops with the 1st mode operation, the lubricant oil 101 of liquid reservoir 25 is supplied with to throttle orifice 59 by liquid supply passage 27 from ostium 53 and the 1st intercommunicating pore 57, takes out of to the outside of compressor by sucking path 40 grades again., along with taking out of of lubricant oil 101, when the liquid level of the lubricant oil 101 of liquid reservoir 25 is low to moderate the ostium 53 of top when following, the refrigerant gas of inner space 13 is in ostium 53 and the 1st intercommunicating pore 57 influent supply passages 27.Thus, lubricant oil 101 just can not taken out of the outside to compressor more than it, the liquid level of liquid reservoir 25 can be guaranteed and below ostium 54 between.Like this, just can prevent in turbocompressor that lubricant oil 101 from not using one-way valve to taking out of of compressor outside.
Again, under the situation after crankshaft 8 stops with the 2nd mode operation, because two ostiums 53,54 are all by apolipsis, so the lubricant oil 101 of liquid reservoir 25 can not be supplied to the lubricant oil supply system more than 102, the liquid level of liquid reservoir 25 can remain in the state that turns round when stopping.Again, under the situation after crankshaft 8 stops with the 3rd mode operation, because throttle orifice 59 is by apolipsis, so the lubricant oil 101 of liquid reservoir 25 can not be supplied to the lubricant oil supply system more than 102, the liquid level of liquid reservoir 25 can remain in the state that turns round when stopping.
On the other hand, under the situation after crankshaft 8 stops with the 1st mode operation since the liquid level ostium up of liquid reservoir 25 53 below and below ostium more than 54, follow, the 1st to the 3rd pattern during entry into service changes to oil condition again.That is to say, in the 1st pattern, utilize the differential pressure of inner space 13 and back pressure chamber 32, space 13 is by ostium 53 and the 1st intercommunicating pore 57 and the lubricant oil 101 of refrigerant gas in the space that is present in lubricant oil supply system 102 in the influent supply passage 27 are supplied with internally.In the 2nd pattern, comprise that liquid supply passage 27 is decompressed to identical with the back pressure of back pressure chamber 32 with the pressure inside of the lubricant oil supply system 102 of storage liquid space 29.In this decompression process, in lubricant oil supply system 102, dissolve in the refrigeration agent foaming in lubricant oil 101, refrigerant gas and lubricant oil 101 are supplied to back pressure chamber 32 by throttle orifice 59.
In the 3rd pattern, lubricant oil is supplied with in the space to the liquid supply passage 27 that is depressurized and the lubricant oil supply system 102 of storage liquid space 29 in the 2nd pattern by ostium 54 and the 2nd intercommunicating pore 58.Therefore, in the turbocompressor of this example,, just lubricant oil can be adjusted to appropriate amount and supply by setting the ratio of bent axle 8 each pattern of the 1st to the 3rd in 1 changes.
Now the turbocompressor to another example of the present invention shown in Figure 5 describes.To identical labels of employing such as the members identical or suitable with turbocompressor shown in Figure 1, and the repetitive description thereof will be omitted.Throttle orifice 59 is communicated with storage liquid space 29 off and in Fig. 1 example relatively, situation about lubricant oil being supplied with to back pressure chamber 32 by slotted hole 30, the turbocompressor of this example is that throttle orifice 59 is communicated with storage liquid space 29 and in fact immovable storage liquid space 30 by slotted hole 30, directly is communicated with off and on also with back pressure chamber 32 and only when being communicated with this back pressure chamber 32 lubricant oil 101 is supplied with to back pressure chamber 32.
Because like this, make revolution turbine 2 form slotted hole 30 to connect ground one end at radial direction from liquid reservoir 28 to periphery, formation to the throttle orifice 59 of storing liquid space 29, and is stopped up the part that extremely is communicated with back pressure chamber 32 from the part that is connected with the throttle orifice 59 of slotted hole 30 from the half-way corresponding with the storage liquid space 29 of this slotted hole 30 with stopper 104., if can in fact obtain same effect, also can make any concrete structure.For example, slotted hole 30 also can make the satisfied locality condition that is not communicated with back pressure chamber 32 and be communicated with storage liquid space 29.This occasion, throttle orifice 59 also can be arranged at from liquid reservoir 28 or store liquid space 29 to the half-way of the slotted hole 30 of back pressure chamber 32 or the aperture position of liquid reservoir 28 or storage liquid space 29 etc.
Referring now to Fig. 2 that has stated (a)-(d) action of the throttle orifice in this example 59 is described.Throttle orifice 59 with (a)-(d) shown in the situation of example of Fig. 1 same, utilize the circular orbit motion of revolution turbine 2, carry out circular motion when between storage liquid space 29 and back pressure chamber 32, striding across sealing component 38 and be communicated with off and on back pressure chamber 32.But, in this example, owing to when throttle orifice 59 is faced with sealing component 38 or storage liquid space 29, be not communicated with back pressure chamber 32, so lubricant oil 101 is not supplied with to back pressure chamber 32.On the other hand, when throttle orifice 59 was faced with back pressure chamber 32, the lubricant oil 101 of liquid reservoir 28 was supplied with to back pressure chamber 32 by slotted hole 30 and throttle orifice 59 without the storage liquid space.Again, relatively in the example of Fig. 1 lubricant oil 101 above the lower direction the situation by throttle orifice 59, then opposite in this example with it, be abscission joint discharge orifice 59 downwards from the top.
In these cases, if the time scale that change throttle orifice 59 and back pressure chamber 32 are faced just can be adjusted the delivery volume to the lubricant oil of back pressure chamber 32.In this occasion, owing to can utilize the various change adjustment of setting track diameter by to circular motion time of formation position and the time scale that back pressure chamber 32 is faced, throttle orifice 59 does not produce and makes little and the unfavorable condition that length is grown of such in the past diameter.
Again, the interval combined action that time scale of facing according to throttle orifice 59 and back pressure chamber 32 and intercommunicating pore 57,58 are communicated with ostium 53,54 for the example explanation of Fig. 1 like that, the same effect that can obtain thus Yu in the example of Fig. 1, illustrate.
Now the turbocompressor to another example shown in Figure 6 describes.But also the repetitive description thereof will be omitted to adopt identical label for the member identical or suitable with the example of Fig. 1.The turbocompressor of this example is provided with the recess 60 that is formed on the fixing runner plate 37 and often is communicated with back pressure chamber 32 with the throttle orifice 59 that replaces Fig. 5 example and be provided with that throttle orifice 61 above-mentioned throttle orifices 61 are formed on the revolution runner plate 33, one is distolateral is communicated with liquid reservoir 28 by slotted hole 30, and another distolateral and above-mentioned recess 60 is communicated with off and on.
Therefore, recess 60 is corresponding with the peripheral part of the fixing revolution runner plate 33 of runner plate 37, and be arranged to and the state of facing mutually from the outer assigned position to the least radius of gyration of the maximum turning radius of revolution turbine 2, the predetermined timing of the opening of throttle orifice 61 in the circular orbit motion of revolution turbine 2 only stipulating during be configured to face recess 60 the position promptly be positioned at the state of the position of connection.Again, throttle orifice 61 utilizes slotted hole 30 to be communicated with liquid reservoir 28.Slotted hole 30 is arranged to connect to periphery from the liquid reservoir 28 of revolution runner plate 33, makes hook-type midway and is connected with throttle orifice 61.The opening to back pressure chamber 32 of slotted hole 30 utilizes stopper 104 to stop up.This occasion also can make and satisfy the state that slotted hole 30 is not connected with storage liquid space 29 with the locality condition of back pressure chamber 32 connections.Again, throttle orifice 61 also can be positioned at make from liquid reservoir 28 arrive recesses 60 states slotted hole 30 midway or be positioned at position to liquid reservoir 28 openings.
Again, the lubricant oil supply system 102 of the example of Fig. 1, Fig. 5 is to arrive liquid reservoir 28 backs arrive the state of storage liquid space 29 by floating bearing 7 situation with respect to the lubricant oil 101 through bearing 20 relatively, lubricant oil supply system 102 at this example is store liquid space 29 for leaving through the lubricant oil 101 behind the bearing 20, and arrives liquid reservoir 28 from this by floating bearing 7.
Relation when the recess 60 when seeing revolution runner plate 33 from the bottom surface moves with throttle orifice 61 is shown in Fig. 7 (a)-(d).From Fig. 7 throttle orifice 61 from the position of (a)-(d) as can be known, along with the rotation motion of revolution turbine 2, the face 55 that is provided with recess 60 in the face of ground with revolution turbine 2 of fixed turbine 1 and this recess 60 mutual respectively intermittently in the face of carry out circular motion.When throttle orifice 61 was faced mutually with recess 60, the lubricant oil of liquid reservoir 28 was supplied with to back pressure chamber 32 from recess 60 by throttle orifice 61.On the other hand, when throttle orifice 61 and face 55 were practised physiognomy, throttle orifice 61 is inaccessible and supplying lubricating oil not by last facial 55.Therefore, in this turbocompressor,, can suitably set delivery volume to the lubricant oil of back pressure chamber 32 by suitably setting the time scale that the throttle orifice 61 of bent axle 8 between 1 refunding and recess 60 are faced mutually.
Again, the action of the combination in the interval that time scale of facing mutually according to throttle orifice 61 and recess 60 and intercommunicating pore 57,58 are communicated with ostium 53,54 as illustrated in the example of Fig. 1, the same effect that can obtain thus Yu in the example of Fig. 1, illustrate.In addition, recess 60 is not limited to circle shown in Figure 7.
Now the turbocompressor to Fig. 8, example shown in Figure 9 describes.But for identical labels of employing such as the members identical or suitable with the example of Fig. 1, and the repetitive description thereof will be omitted.In the example of Fig. 1, on bearing support 52 and crankshaft 8, be set up in parallel each 2 the ostium 53,54 and the situation of intercommunicating pore 57,58 relatively respectively, in this example, single ostium 62 and intercommunicating pore 63 are set respectively on bearing support 52 and crankshaft 8.
Below with reference to the explanation of Figure 10 the ostium 62 of the position of throttle orifice 59 and bearing support 52 and relation with relative position intercommunicating pore 63 crankshaft 8 are described.Now the state that intercommunicating pore 63 and storage liquid space 29 are faced is as connecting section intermittently, with any state of facing mutually of intercommunicating pore 63 and sealing component 38 or back pressure chamber 32 apolipsis interval as intermittence.Again, the state that intercommunicating pore 63 is overlapped with ostium 62 is as connecting section intermittently, and the state that intercommunicating pore 63 and ostium 62 are not overlapped is as the apolipsis interval at intermittence.Crankshaft 8 is between 1 refunding, by the combination results in above-mentioned connecting section and apolipsis interval the 1st and the 2nd pattern shown in Figure 10.
In the 1st pattern,, be decompressed to identical with the space pressure of the lubricant oil supply system 102 of storage liquid space 29 with the back pressure of back pressure chamber 32 so comprise liquid supply passage 27 because intercommunicating pore 63 apolipsis and throttle orifice 59 are communicated with storage liquid space 29.In this decompression process, in lubricant oil supply system 102, dissolve in the refrigeration agent foaming in lubricant oil 101, refrigerant gas and lubricant oil 101 are supplied with to back pressure chamber 32 by throttle orifice 59.
In the 2nd pattern, in the space of the lubricant oil supply system 102 of the liquid supply passage 27 that lubricant oil 101 is depressurized in being included in the 1st pattern by ostium 62 and intercommunicating pore 63 and the storage liquid space 29 of high pressure.Therefore, in the turbocompressor of this example,, lubricant oil 101 can be adjusted to appropriate amount and supply with by setting the 1st and the 2nd pattern of crankshaft 8 between 1 refunding.
Below compressor is described from the state of operating condition when stopping.Occasion after crankshaft 8 stops with the 1st mode operation, because intercommunicating pore 63 is by apolipsis, so the lubricant oil 101 of liquid reservoir 25 is not supplied with to lubricant oil supply system 102, the liquid level of liquid reservoir 25 is maintained at the state that turns round when stopping.Again, the occasion after crankshaft 8 stops with the 2nd mode operation, because throttle orifice 59 is by apolipsis, so the lubricant oil 101 of liquid reservoir 25 is not supplied with to lubricant oil supply system 102, the liquid level of liquid reservoir 25 is maintained at the state of rotation when stopping.
In this turbocompressor, though become rough a little with the adjustment of the delivery volume of the example comparison lubricant oil 101 of Fig. 1, but, lubricant oil 101 can be adjusted to appropriate amount and supply with by suitably setting the time scale of the 1st and the 2nd pattern of bent axle 8 between 1 refunding.
Again, even the throttle orifice 59 shown in the example of employing Fig. 5 is communicated with, passes through slotted hole 30 off and on the structure of lubricant oil to back pressure chamber 32 supplying lubricating oils with back pressure chamber 32, be communicated with off and on storage liquid space 29 to replace throttle orifice 59, situation by slotted hole 30 is supplied with from lubricant oil to back pressure chamber 32 also can obtain the effect same with this example.
Again, even will be provided with the recess 60 shown in the example of Fig. 6 and the structure of throttle orifice 61 makes up, be communicated with storage liquid space 29 off and on, lubricant oil 101 supplied with the situation that back pressure chamber 32 is supplied with to replace throttle orifice 59, also can obtain the effect same with this example by slotted hole 30.
Now the turbocompressor to example shown in Figure 11 describes.But, the member identical or suitable with the example of Fig. 8 etc. adopted identical label, and the repetitive description thereof will be omitted in the example of Fig. 8 single ostium 62 and intercommunicating pore 63 is set respectively on bearing support 52 and bent axle 8 relatively, and be that intercommunicating pore 63 and liquid reservoir 25 are arranged to the state that directly often is communicated with the turbocompressor that the inlet opening 64 of pressure adjustmenting mechanism 39 and back pressure chamber 32 are arranged to this example of situation of connected state, and the path 103 that emits of the lubricant oil 101 of relative pressure regulating mechanism 39 is provided with the inlet opening 64 that intermittently is communicated with along with the rotation of crankshaft 8 and back pressure chamber 32.
Again, the lubricant oil supply system 102 of this example is supplied to bearing 20 and liquid reservoir 28 for the liquid supply passage 27 in crankshaft 8 by shunting, the lubricant oil 101 that bearing 20 is left after lubricated enters storage liquid space 29 same as before, and the lubricant oil 101 that enters liquid reservoir 28 arrives storage liquid space 29 by floating bearing 7 and to its lubricated back.
Revolution runner plate 33 when revolution runner plate 33 turbocompressor is seen in expression from the bottom surface among Figure 12 (a)-(d) and inlet opening 64 relation when action.From Figure 12 each position of (a)-(d) as can be known, inlet opening 64 along with the revolution turbine 2 rotation motion from the revolution runner plate 33 be communicated with off and on back pressure chamber 32.In the inlet opening 64 with back pressure chamber 32 in the face of the time, the lubricant oil 101 of back pressure chamber 32 is emitted to the suction zone of compression volume 3 from sucking path 40 by inlet opening 64 and pressure adjustmenting mechanism 39.Eliminate the surplus of back pressure thus, and lubricant oil 101 is supplied with to the fixed turbine 1 and the slide part of revolution turbine 2.On the other hand, 64 by revolution runner plates 33 when inaccessible in the inlet opening, and lubricant oil 101 do not emit, not to above-mentioned supply.Therefore, in this turbocompressor,, just can suitably set delivery volume to the lubricant oil of compression volume 3 by suitably setting the time scale that the inlet opening 64 of crankshaft 8 between 1 refunding and back pressure chamber are faced.
Again, the action that time scale that is communicated with back pressure chamber 32 according to the inlet opening 64 with compression mechanical part 14 and throttle orifice 59 make up in the face of the time scale of back pressure chamber 32 as illustrate in the example of Fig. 8, so can obtain and the example of Fig. 8 in the same effect that illustrated.
Again, be communicated with, pass through slotted hole 30 is supplied with structure from lubricant oil 101 to back pressure chamber 32 off and on back pressure chamber 32 at the throttle orifice 59 shown in the example of Fig. 5 even adopt, the situation that is communicated with off and on, by slotted hole 30 lubricant oil 101 is supplied with to back pressure chamber 32 with storage liquid space 29 with replacement throttle orifice 59 also can obtain the effect same with this example.
Again, even will make up, be communicated with off and on storage liquid space 29 to replace throttle orifice 59, lubricant oil also can be obtained the effect same with this example to the situation of back pressure chamber 32 supplies by slotted hole 30 in the structure that recess 60 and throttle orifice 61 are set shown in the example of Fig. 6.
Now the turbocompressor to example shown in Figure 13 describes.But to identical labels of employing such as the members identical or suitable with the example of Figure 11, and the repetitive description thereof will be omitted.Intercommunicating pore 63 directly often is communicated with liquid reservoir 25 in Figure 11 example relatively, throttle orifice 59 intermittently is communicated with storage liquid space 29 and pass through slotted hole 30 is supplied with situation from lubricant oil 101 to back pressure chamber 32, in the turbocompressor of this example, single ostium 62 and intercommunicating pore 63 are set and along with the revolution of crankshaft 8 intermittently is communicated with respectively on bearing support 52 and crankshaft 8, and the liquid supply passage 27 in back pressure chamber 32 and the crankshaft 8 also often is communicated with by lubricant oil supply system 102 and restriction 65.
Restriction 65 is utilized lubricant oil supply system 102 and is formed at it midway to the end.Specifically utilize by forming as the gap between formed crankshaft 8 of sliding bearing and the bearing 20 with bearing 20.Again, also can utilize by same gap as the floating bearing 7 of sliding bearing, can also be by the ground throttling of 20,7 both sides' two-stages of two bearings.Certainly, also can utilize gap between part beyond the bearing portion.Therefore, because storage liquid space 29 is supplied to through the post-decompression lubricant oil 101 in restriction 65 backs, so with set pressure differential not between the back pressure chamber 32, or just can obtain for back pressure chamber 32 necessary decompression states with the restriction effect of the slide part of 21 of dual-purpose revolution turbine 2 and main bearing members.Therefore, the sealing component between storage liquid space 29 and the back pressure chamber 32 omits.In this example,, has the back pressure effect respectively owing to the effect of easing stress that is set by liquid reservoir 28, storage liquid space 29, the restriction separately 65 of back pressure chamber 32 becomes roughly the same pressure.
Again, intermittently overlapping action that the time scale that is communicated with makes up according to the time scale that the inlet opening 64 of pressure adjustmenting mechanism 39 and back pressure chamber 32 intermittently are communicated with and intercommunicating pore 63 and ostium 62 is as illustrating in the example of Fig. 8, so the same effect that can obtain and illustrate in the example of Fig. 8.Again, by restriction 65 is set on lubrication oil supply system 102, owing to can not being arranged on throttle orifice such in the another example 59 and sealing component 38, so can be with lower cost acquisition and the same effect of example of Fig. 8.
In sum, if adopt turbocompressor of the present invention and method for driving thereof, make up by connected state at least one side obtained intermittence of two of emitting the path of utilizing the excess liquid of coming from liquid supply path and back pressure chamber to back pressure chamber, can adjust to the amount of back pressure chamber lubricant oil that supply with or that be supplied to and can easily set the back pressure of various scopes according to machine and running state, and, can carry out repetition with rotating correct timing and cycle owing to above-mentioned intermittently be communicated with, so can have high efficiency according to the lubricant oil of the running supply appropriate amount in machine and each period thereof along with the axle of driving rotational turbine.
Again, even for using throttle orifice not form pore by with the combination of ostium and intercommunicating pore owing to can suppress the delivery volume of lubricant oil as required, so can not produce phenomenon such as obstruction, can obtain high reliability, and owing to can be that simple hole processes and can not cause the cost rising.Again, though be not provided with one-way valve also since can prevent running when stopping lubricant oil taking out of and further improve reliability to the compressor outside.
