Description

High compression ratio volumetric fluid displacement device

The present invention is relevant with the displacement fluid compression set.More particularly, the present invention is an improved volumetric fluid compression set, and wherein the mechanism that is referred to as fluid front end sealing by us is achieved the warp-wise sealing between the pressure air chamber of this device.In addition, the invention provides us and be referred to as to call the mechanism that centrifugal oil separates, it can reduce by the quantity of discharging the entrained oil of going out of gas.

The technology of volumetric fluid compression set is well-known, and the U. S. Patent 802,182 of for example granting Creux has disclosed a kind of scroll type device.This device comprises two scroll members, and each scroll member has the scrollwork of an end face square position and spirality or involute shape.These two scrollworks have identical geometrical shape, mesh each other and are kept at an angle and radial deflection, to cause many places line contact between their spiral curved surfaces.So, intermeshing scrollwork has formed at least one pair of fluid air chamber that is sealed.When a scrollwork was done orbiting with respect to another scrollwork, above-mentioned Line of contact just moved along spiral camber, thereby the fluid gas chamber volume changes thereupon.The increase of volume or reduce to depend on the direction of relative movement between two scrollworks, like this, this device can be used for compression or expansion fluid.

Below with reference to Fig. 1 a-1d the general running principle of traditional scroll compressor is done some explanations.Fig. 1 a-1d schematically shows intermeshing spiral scrollwork 1 and 2 and does relative movement with compressed fluid, and scrollwork 1 and 2 is meshing with each other and is being kept at an angle skew and radial deflection each other.Fig. 1 a has shown that the outer end of each scrollwork contacts with another scrollwork, and just expiratory phase is just finished, the fluid air chamber A of a pair of symmetry ₁And A ₂Just form.

Fig. 1 b-1d has shown that successively the live axle crank has rotated the position of scrollwork behind the several angle.When song changes rotation, fluid air chamber A ₁And A ₂Radially to move while A gradually to the center of engagement scrollwork with certain angle ₁And A ₂Volume gradually reduce.Fluid air chamber A ₁And A ₂When the angle of bent axle when the state shown in Fig. 1 c arrives state shown in the 1d, combine at core A place.When main shaft continued rotation, the air chamber after the above-mentioned merging further reduced its volume.When scrollwork was done relative orbiting, the space outerpace shown in Fig. 1 b and the 1d progressively changed to form new sealed air chamber, wherein to seal and is about to compressed next fluid volumes (as the state shown in Fig. 1 c and the 1a).

There are three kinds in the existing scrollwork design in order to keep scroll member in " axle " method to the kinematic relation of (along the direction of scrollwork center shaft axis).These methods can be called " fixed interval (FI) " method, " axially being obedient to " method and " semiaxis is to being obedient to " method.

In the device in early days, employing be the fixed interval (FI) method, for example grant U.S. Patent No. 801, the 182 fixed interval (FI) method of Creux.In this method, close in axial mutual alignment between the scroll member and tie up to assembling and just can not change again after finishing.Wherein, do not contact mutually under normal conditions between the bottom of the front end of a scroll member and another scroll member.In order to keep when moving, axially having appropriate gap between the scroll member, keep high compression efficiency again simultaneously, this just requires high machining accuracy.Another comparatively serious problem is that this a kind of structure can't tackle abnormal conditions; if for example have foreign material particle or incompressible liquid in the scroll member, perhaps the excessive increase owing to heat contacts with each other between the bottom of the front end of scroll member and another scroll member.Under these abnormal conditions, scroll member can cause damaging owing to biting.

In order to overcome the weakness of fixed interval (FI) method, all axial compliant structures have been developed.These structures can be divided into two big classes: " mechanical forward end seal " and " fully axially being obedient to ".

Fig. 2 shows the forward end seal structure.The example of another forward end seal can be referring to the U.S. Patent No. 3,994,636 of granting Mc Cullough.As shown in Figure 2, respectively have a groove 501 at the middle part of the front end of scroll member 502 and 503.One Sealing 504 is embedded groove 501 movably, and is promoted by machinery or hydrodynamic pressure (not drawing among the figure) and contact with the bottom 505 of another scroll member.So just can prevent that fluid from passing through the radial leakage between scrollwork 502 and 503.Yet, exist the passage of intrinsic tangential leakage in the forward end seal structure, shown in Fig. 2 center line A-A and B-B.These leakage ways have reduced compression efficiency.This in addition forward end seal method also exists the problem of the power loss that causes of friction and the sealing effect decline that causes because Sealing weares and teares gradually.

In complete axially compliant structure, scroll member keeps contacting of front end and bottom between scrollwork, thereby no matter be under what kind of pressure condition, all keeps the sealing state of fluid air chamber under mechanical force or hydrokinetic effect.The U.S. Patent No. 3,600,114 of granting people such as Devorak has disclosed a fully axially compliant structure.Wherein at least one scroll member be subjected to machinery and (or) effect of the axial force of fluid, keeping the front end of two scroll members and the sealing of bottom to contact.In the patent of ' 114, the fluid with exhaust pressure is used to apply a biasing force at the back of the end face square position of scroll member.The U.S. Patent No. 3884,599 of granting people such as Young has disclosed a kind of fully axially compliant structure.Wherein be subjected to having the axial Driving force of the fluid of exhaust pressure around the scrollwork of orbiting.The U.S. Patent No. 4,357,132 of granting Kousokabe has disclosed a kind of wrap machine, wherein will push fixed scroll member to around the scroll member of orbiting with the fluid with intermediate pressure (pressure is advancing, between the exhaust pressure).The U.S. Patent No. 4,216,661 of granting Toj has disclosed a kind of fully axially compliant structure.Wherein the fluid in scrollwork machine outside is introduced in back around orbiting scroll so that axial biasing force to be provided.Grant the U.S. Patent No. 4 of Blain, 611,975 have disclosed a kind of fully axially compliant structure, a doughnut that wherein forms on the surface of contact of two scroll members, it is connected with lower pressure source and causes negative pressure, thereby with two scroll members " suction " together.The U.S. Patent No. 4,496,296 of granting Arai has disclosed a kind of fully axially compliant structure, has wherein formed two pressure chambers at the back around the scroll member of orbit rotation.These two pressure chambers are connected with the central volume that is in exhaust pressure with the compression air chamber of the pressure that mediates respectively.This structure can keep the radial seal of scroll member in bigger damage condition and range.Grant people's such as Caillat U.S. Patent No. 4,767,293 and No.4,877,382 have disclosed a kind of mechanism that fully axially is obedient to, the non-scroll member that wherein has an elastic fixing device around orbit rotation mediating pressure or (with) be in the scroll member that is pushed under the effect of gas pressure of exhaust pressure around orbiting.

Fully axially compliant structure has some defectives: for example, owing to be used in gas pressure in these structures often from compression air chamber and/or exhaust chamber, and thereby this pressure can change such as the change of air-breathing and exhaust pressure along with operating condition.Yet this variation is always not proportional with the Separating force of front end that acts on scroll member and bottom.The result who takes into account in the design and compromise is, if axial bias power is enough in certain any operating conditions scope, just may be not enough to keep stable work under lower air-breathing and exhaust pressure.On the other hand, just may seem too big under the operating conditions of this axial bias power and exhaust pressure air-breathing at height.

Fully axially another shortcoming of compliant structure is that it provides the frictional power loss on surface can not ignore.When mechanical movement under the condition of higher air-breathing and exhaust pressure, excessive axial gas biasing force causes big frictional power loss and serious wearing and tearing.Damage entire machine to biting sometimes even seriously owing to the friction of front end and bottom.

Fully axially to also have a shortcoming be that axial contact of scrollwork front end and bottom can produce vibration and noise to compliant structure.

The U.S. Patent No. 4,958,993 of granting Fujio has disclosed the third structure that keeps the gap between the scroll member.This method thereby is called semiaxis to compliant structure because the axial clearance between scrollwork can change by changing the scrollwork axial position.

U. S. Patent ' 993 think can axially movable should be scroll member around orbit rotation, rather than non-scroll member around orbiting.This patent is thought can reduce to minimum to the movable part sum like this, because be kept in motion originally around the scroll member of orbiting but not just remained static originally around the scroll member of orbiting.Moving element then is the vibration that will avoid of people and the source of noise.In addition, the scroll member around orbiting always comes lightly than non-scroll member around orbiting usually.These, less inertia can make the scroll member around orbit rotation react sooner.

Begin at this paper mentioned, the U.S. Patent application Ser.No.07/931 of pending trial, 011 provides a kind of semiaxis that has improved to the biasing mechanism of being obedient to, and has eliminated possible the rocking and colliding of scrollwork, thereby has greatly lowered noise, vibration and leaking.

Although above-mentioned all structures have had bigger improvement, wherein still inevitably the front end of a scrollwork and and the bottom of another scrollwork between have the gap.This is because the core of scrollwork is in higher temperature, thereby has bigger axial thermal expansion compared with its periphery.This temperature difference is along with operating conditions, weather for example, cooling, the variation of load etc. and changing.Gap between the bottom of anterior and another scrollwork of one scrollwork makes working fluid leak between each compression air chamber, thereby has reduced energy efficiency, and may cause too high fluid temperature (F.T.).

The present invention, we are referred to as the mechanism of fluid front end sealing at this, thereby by the viscosity of high pressure, front end that lubricant oil is incorporated into scrollwork having been kept the radial seal between the pressure air chamber.The lubricant oil of being introduced provides operating sealing, lubricated cooling.The method of fluid front end sealing can be used in " fixed interval (FI) ", be obedient to and partly be obedient to etc. in the various structures fully, the present invention also further provides a kind of new mechanism to come oil from discharging gas separation before lubricant oil flows out scroll devices, flows out scroll devices to prevent excessive lubricant oil.

According to as mentioned above, one of aim of the present invention provides a volumetric fluid compression set, and the viscous lubrication oil of its mesohigh is introduced in the front end of scrollwork to form oil film.This oil film, we are referred to as the fluid front end sealing.Like this, the present invention has eliminated the radial leakage between each compression air chamber.

Another aim of the present invention provides a kind of new method, scrollwork is in operation can obtains lubricated fully and cooling.

The present invention also has an aim to provide a kind of new structure, and it can be separated lubricant oil from discharge gas, taken out of scroll devices to prevent excessive lubricant oil.

In order to realize above-mentioned and other purpose, one embodiment of the present of invention provide a volumetric fluid compression set, and it includes a housing that fluid inlet and outlet is housed, and one has first scroll member of an end face square position.Have first scrollwork to extend vertically from this square position, enter the inside of housing, also have one second scroll member, it also has an end face square position.Above it, there is second scrollwork to extend vertically.Second scroll member can be done the orbiting of nonrotary with respect to first scroll member.

First and second scrollworks, thus mesh together to cause the many places line to contact qualification or to have formed at least one pair of fluid-encapsulated chamber to be kept at an angle mutually with mode with radial displacement.

Drive unit links to each other with scroll member, thereby prevents to relatively rotate the change of reaching the fluid gas chamber volume to realize relative orbiting between the scroll member.

The example that the present invention discloses provides a kind of volumetric fluid compression set, and the viscous lubrication oil of its mesohigh is introduced into the front end of at least one scrollwork.This flow of lubricant forms one deck oil film through the front end of a scrollwork and the gap between another scrollwork bottom.This oil film has been sealed between the compression air chamber leakage way radially, and lubricated between scroll member front end and the bottom is provided.

This fluid front end sealing mechanism has been introduced a considerable number of lubricant oil to scrollwork compression air chamber.Because the thermal capacity of liquid lubricant oil is much larger than compressed gas, thereby thereby lubricant oil can from be compressed gas, absorb the temperature that a large amount of heats reduce discharge gases and then whole scroll devices.If scroll devices operates under the state of lower effluent air temp, just can improve its energy efficiency and reliability.Oil film is formed between the sidewall of scrollwork, provides lubricated while between sidewall that tangential sealing between the compression air chamber also is provided.

Yet allowing to be discharged from gas, to take the oil mass of scroll devices out of be limited.For this reason, the invention provides a kind of new structure so that too much lubricant oil is separated from discharge gas.In this structure, the mixture of discharging gas and lubricant oil is by discharging at the tap hole around the center of the scrollwork of orbiting, flows through then along the passage of the center line of main shaft.Mixture is by the nozzle ejection with the end of the main shaft of high speed rotating.Because oil and the greatest differences of exhausting air on density, they are separated when the main shaft of high speed rotating sprays.Flow of lubricant is to the oil sump of bottom, and is cooled at this, and compressed gas then rises, and is discharged by relief opening.

With reference to accompanying drawing reading detailed description hereinafter, the present invention will more easily be understood.

Fig. 1 a-1d shows the situation that scrollwork in the scroll compressor of prior art is made relative track movement;

Fig. 2 shows the structure of a typical forward end seal of prior art;

The cross-sectional view of the scrollwork air condition compressor that Fig. 3 shows according to the present invention to be built;

The view that Fig. 4 a-4c shows according to the present invention to be built around the scroll member of orbiting; And

Fig. 5 shows the cross-sectional view of second example of the present invention.

See also Fig. 3.Fig. 3 shows a scroll type air condition compressor designed according to this invention.Compressor 10 comprises mainframe 20, compressor case 21 and end cap 22 and lower end cap 23.Upper end cap 22 links to each other with compressor case 21 with the method for knowing (for example welding).Lower end cap 23 also links to each other with shell 21 with the method for knowing (for example welding).On the mainframe 20, main radial bearing 30 is housed.Main shaft 40 is supported by bearing 29 and 30, and can be around its axis S ₁Rotation under motor 41 drives.

One drive pin 42 is stretched out by the tail end of main shaft 40.This drive pin central axis S ₂Central axis S with main shaft ₁One skew is arranged each other.This offset distance equals the radius R around orbiting of second scrollwork _OrSo-called around the orbit radius of orbiting radius when to be second scroll member 50 with respect to first scroll member 60 do the track circular motion of nonrotary.

First scroll member 60 has an end face square position 61, and scrollwork 62 extends thus.First scroll member 60 to be being disclosed in the U.S. Patent application ser of pending trial, No.07/931, and so-called " partly being obedient to " mode is fixed on the mainframe 20 in 011.According to this mode, first scroll member 60 and axis S ₁A plane 24 perpendicular and that under bias force effect, withstand mainframe 20 by the discharge gas that acts on surface 66.Between the bottom of the end plate of the front end of the scrollwork of a scroll member and another scroll member, just kept appropriate gap like this.This gap is represented with 65 in Fig. 3.

This gap is must be enough big, even so that tolerance is arranged on making and still can avoid the front end of scroll member under the normal operation thermal expansion existence being arranged and the bottom between contact with each other.On the other hand, this gap again must be enough little seals at the lubricant film that the radial leakage between the compression air chamber can be formed in the gap guaranteeing.This layer oil film is referred to as the fluid front end sealing in this article, and will go through hereinafter.When improper situation occurred, for example, when foreign material particle incompressible fluid enters between the scroll member, or scrollwork was when abnormal thermal expansion having occurred, and first scroll member damages to prevent scrollwork with the bias force of adverse current body and axially doing to keep out of the way motion.

Except end face square position 61 and scrollwork 62, first scroll member 60 also includes strengthening sleeve 63 and strengthening rib 64.First scroll member can be made small offset movement to the axis caudal directions along axis.Scrollwork 62 is fixed on the end face square position 61 and extends from the end plate front-end face, and 64 of strengthening sleeve 63 and strengthening rib extend from the end plate rear surface.

Second scroll member 50 includes an end face square position 51, and is fixed on the end plate 51 and the scrollwork 52 that extends from the end plate rear surface, and is fixed on the front surface of end plate 51 and the bearing support 53 around orbiting that extends out from this surface.

Scrollwork

52 and 62 intermeshes, and keeps the phase difference of 180 degree radially then keeping around the orbiting radius R on angle _OrDisplacement.So,

scrollwork

52 and 62 and end face square position 51 and 61 between form a pair of sealed air chamber at least.Second scroll member 50 is connected with drive pin 42 by drive pin bearing 43.The effect of Oudan ring 45 is to prevent that second scroll member 50 from rotating.Under the driving of main shaft 40, second scroll member 50 is with the radius R that sways _OrDo orbiting with compressed fluid with respect to first scroll member 60.Working fluid enters compressor 10 from 91 inlets 93 through air chamber 92 and fixed scroll member 60 that enter the mouth, and enter by

scroll member

50,60 formed induction chambers 95, compressed by scroll member then, at last by exhaust port 70, through

exhaust passage

71,72, nozzle 73, exhaust chamber 80, exhaust passage 74 and relief opening 75 and discharge.The gas that is discharged from the air chamber 94 does not communicate with air chamber 92, and it is that sealed circle 44 seals.

Weight equalizer 97 and 98 in order to balanced action on second scroll member 50, owing to it makes the centrifugal force that orbiting produces.

One Sealing 81 is the whole volume separated into two parts in the shell: bottom volume 80 and upper volume 92.Volume 80 is in high pressure, and volume 92 is in low pressure.

Pressurized gas in the volume 80 the lubrication pressure in the oil sump 82 of compressor bottom to front portion 52 around the scroll member 50 of orbiting.The approach of its oil circuit is by pipeline 31,

passage

32,33 and 34 and scroll member 50 in passage 35 form.Oil circuit can be positioned at casing inside as shown in the present embodiment, also can be positioned at the outside of casing.

Now please referring to Fig. 4 a-4c, there is a groove 36 front portion of scrollwork 52, and this groove 36 can be along the partial-length of spiral wraps 52 or all length extensions.But 36 1 continuous grooves of groove also can be divided into several sections.Lubricant oil is by flowing out in the groove 36, and forms one deck oil film and be full of around the scrollwork front end of orbiting and the gap between the fixed scroll bottom.This lubricant film has cut off and has been compressed the radial leakage passage of gas between compression air chamber.

Lubricant oil also is allowed to flow into compression air chamber.Drive lubricant oil around the orbiting of the scrollwork of orbiting and not only formed, also formed at non-front end and the oil film between the bottom of orbiting scroll spare 60 around orbiting scroll spare 50 at the oil film between the gap between the scrollwork sidewall.These oil films have also cut off possible leak path between each compression air chamber in lubricated each friction surface.In addition, lubricant oil has also cooled off and has been compressed gas and has reduced the temperature of discharging gas.And the temperature decline of discharging gas means the increase of the energy utilization efficiency of this device.

The lubricant oil that is introduced in compression air chamber need be separated from discharge gas, enters the external system that links with compressor to prevent excessive oil.Back referring to Fig. 3, be compressed gas in the present invention and leave scroll member via the exhaust port 70 that is positioned at around the scrollwork center of orbit rotation.Discharge gas flow through then on the moving scrollwork of track passage 71 and enter air chamber 80 along the passage 72 of spindle centerline by the nozzle 73 of main shaft end.The mixture that oil is gentle is sprayed by nozzle 73 with high speed owing to quickened by main shaft.Because greatest differences on density between oil is gentle, act on centrifugal force on the oil droplet much larger than the centrifugal force that acts on the gas.Oil droplet will continue to keep its downward momentum and the inwall of mind-set lower end cap 23.And be compressed gas after nozzle 73 ejections, and be easier to change the direction that it moves downward, rise along passage 74 earlier, discharge by relief opening 75 then.Part oil droplet is beaten on inwall, and flows into bottom oil sump 82.Another part oil is beaten on inwall and is splashed, and blocks and can not reenter air-flow but covered 83 by oil.Be maintained at very low level by discharging gas institute entrained oil amount like this.

Above-described first example of the present invention is called as " single fluid forward end seal ".Wherein extreme pressure lubricant just is introduced in the front end of a scrollwork.

The second embodiment of the present invention is referred to herein as the two-fluid forward end seal, and is presented among Fig. 5.Second embodiment's basic design principle is the same with first embodiment.Different is that in a second embodiment, high pressure oil is introduced at the same time in the front end of two scroll members 50 and 60.High pressure oil is guided to the same with described in first embodiment of passage that the scroll member front end around orbit rotation goes.High pressure oil then is via oil pipe 31,

passage

32,36,37 and 38, finally the front end that is introduced in non-scrollwork around orbit rotation by passage 39 forms the fluid front end sealing, and its sealing principle is the same with form the principle that seals around the front end of orbiting scroll in first example.Lubricant oil also lubricates and has cooled off scroll devices.Discharge the entrained too much oil of gas and come from gas separation by action of centrifugal force, its working principle is the same with described in first embodiment also.
