Therefore, the object of the present invention is to provide the leaf type pump avoiding this defect.
In order to realize this object, propose following leaf type pump, the rotor that this leaf type pump has housing and can drive rotatably, this rotor that can drive rotatably has multiple groove and has in the rotor with the blade that the mode that can be shifted is arranged.Rotor is contained in pump space together with blade, and the side surface in this pump space is pressed against rotor in a sealing manner and is pressed against the blade be contained in groove.Space between side surface is delimited in outside by following surface: namely, this surface is formed as lift profile and is pressed against this surface at the lower outside blade tip of the situation that leaf type is pump operated.Therefore, between the blades, form transfer chamber, when pump operates, the volume of this transfer chamber is transformable.In the side surface in pump space, be provided with port, at least one port in described port is for filling transfer chamber and being designated as inhalation port.At least one other port is for discharging medium, and this medium is transmitted by transfer chamber and this medium is pressed under stress and is supplied to the conveyor zones of leaf type pump in these ports.Leaf type pump transmits medium, and this medium comprises: water, alcohol---such as ethanol, the mixture of ammonia or other organic liquids or described material.In addition, this medium comprises oiling agent, and the proportion of this oiling agent is higher than the proportion of all the other compositions of medium.Oiling agent is used for lubricating the contact area between rotor and side surface and the contact area between blade and side surface, and for lubricating the contact area between the outer end of blade and lift profile.In order to avoid be used in when medium be also referred to as Rankine process heat recovery method in time defect, oiling agent share should be very high, because this has detrimental effect in the evaporation circuit of heat recovering device.In order to ensure sufficient lubrication, especially, in the special loading area contacted with lift profile at blade, although oiling agent share reduces, there is following setting according to the present invention: namely, wherein, the one-tenth of the edge placement towards lift profile of port and lift profile are in a distance.Therefore, if observe the side surface place with port in pump space, it is clear that port has edge, wherein, have outward edge and lower limb, edge surface to lift profile, lower limb be positioned at opposite position and lower limb roughly towards the center in pump space.The feature of the leaf type pump herein related to be outward edge be arranged to lift profile in a distance, make when leaf type pump is in operation, due to the centrifugal force generated by the rotation of rotor and the rotation of blade unit, liquid starts to be pressed against lift profile.Form Breakup of Liquid Ring, the thickness of this Breakup of Liquid Ring is corresponding with the distance at the edge towards lift profile of port.Because oiling agent has higher proportion compared with all the other compositions of the medium transmitted by blade unit, form oiling agent ring at lift profile place, due to the distance at the edge of port, this oiling agent ring is not from the port effusion that the medium of pressurization is discharged.When leaf type pump is in operation, edge forms oiling agent ring, and oiling agent is separated in oiling agent ring from all the other compositions of medium.This oiling agent is not discharged from pump space, thus this oiling agent does not enter the conveyor zones of leaf type pump.So there is no the evaporation circuit being supplied to heat recovering device.
By the oiling agent annular along lift profile being become, there is the thickness corresponding with the distance of the outward edge of port apart from lift profile, ensure that closed lubricant film, this is because the region of standing extra high wear load of pump is the region that blade tip contacts with lift profile just.The oiling agent of high concentration, therefore, it is possible to exactly for this eroded area, makes the wearing and tearing in leaf type pump be reduced to minimum.Because port is apart from the distance of lift profile, after all define Breakup of Liquid Ring, the high percentage in this Breakup of Liquid Ring is made up of oiling agent.Therefore, reduce to a great extent from the oiling agent share the medium that port is discharged.
In the preferred illustrative mode of execution of leaf type pump, there is following setting: wherein, the external frame of rotor be also arranged to lift profile in a distance.Therefore, the Breakup of Liquid Ring set up in the operation period of leaf type pump is not interfered, particularly do not interrupted by rotor, make on the one hand, undisturbed lubricant film can be used for blade unit in the end contacted in region with lift profile, on the other hand, ensure that and can form int oiling agent ring on lift profile, make the oiling agent share of the outside of the port reducing to be arranged in conveyor zones.
In particularly preferred illustrative embodiments, there is following setting: wherein, the edge of port is suitable for far from the outer surface of the distance of lift profile and rotor each other apart from the distance of lift profile, preferably has equal size.
In particularly preferred illustrative embodiments, have following setting: wherein, on the one hand the edge of port apart from the distance of the outer surface distance lift profile of the distance related to of lift profile, on the other hand rotor herein in the scope of 0.1mm to 2mm, preferably in the scope of 0.7mm to 1.3mm.The distance of 1mm is particularly preferred.
In addition, the object of the present invention is to provide the heat recovering device without these defects.
In order to realize this object, heat recovering device is proposed, this heat recovering device has evaporation circuit and transmits the leaf type pump of medium to be evaporated, this medium comprises oiling agent, the proportion of this oiling agent is higher than the proportion of all the other compositions of medium, and/or the viscosity of this oiling agent is higher than the viscosity of all the other compositions of medium.
Below by way of accompanying drawing, the present invention will be described in more detail.Unique accompanying drawing illustrates the basic diagram of a part for leaf type pump with longitudinal cross-section, wherein, rotor is arranged in pump space.
Accompanying drawing illustrates to have housing 3 and a part with the leaf type pump 1 of rotor 5 with sectional view, and this rotor 5 has multiple groove 9 in its matrix 7.These grooves 9 are radially arranged relative to the medial axis 11 of rotor 5, and this medial axis 11 extends perpendicular to the picture plane of accompanying drawing.Groove 9 is preferably arranged in distance mode equidistant each other in circumferential direction relative to rotor 5.Can freely select in the quantity of broad scope inside groove.In the illustrative embodiments herein illustrated of leaf type pump 1, rotor 5 has eight grooves 9, shows three grooves 9 in described eight grooves 9 herein.Groove 9 extends along the direction of the vertical radial line of imagination 13 and another groove 9 extends on the horizontal radial line 15 of imagination.Another groove 9 is also arranged on imaginary angular bisector between described two grooves.In the leaf type pump illustrated herein, in each situation, be provided with another groove relative with the groove illustrated herein, and similarly, with the groove on angular bisector symmetrically, be provided with another groove and eight groove relative with this groove in the upper right corner.
Be furnished with blade 17 in groove 9, blade 17 can at groove internal shift and preferably fully filling slot and be pressed against the lateral inner surface of groove 9 in a sealing manner.In eight blades of the illustrative embodiments illustrated of leaf type pump 1, still illustrate only three blades herein.
Transfer chamber 19 and transfer chamber 21 are between two continuous blades, and in the operation period of leaf type pump 1, the volume of transfer chamber 19 and transfer chamber 21 changes.The housing 3 of leaf type pump 1 has the pump space 23 comprising sidewall.A sidewall in sidewall 25 reproduces with plan view in cross section diagram with reference to the accompanying drawings.Pump space 23 is laterally delimited by following two sidewalls, namely, described two sidewalls be parallel to each other arrange and described two sidewalls are placed to following distance apart: namely, described distance is chosen to make sidewall be pressed against the side surface of rotor 5 and the side surface of blade 17 in a sealing manner.
Pump space 23 by internal surface around, this internal surface is around rotor 5 and be called as lift profile 27.Just the most in the broadest sense, this forms in the mode of ellipse the leaf type pump 1 realizing having two transmission spaces, and described two transmission spaces are arranged symmetrically relative to vertical radial line 13 and itself is formed symmetrically relative to horizontal radial line 15.Transmission space is sickle-shaped.
Port 29 and port 31 are introduced in sidewall 25.Preferably, in sidewall unshowned, not staggered relatively with sidewall 25 in this article, same port is provided with.In addition, other ports relative to horizontal radial line 15 symmetry are provided with.
When leaf type pump 1 is in operation, the medium transmitted by leaf type pump 1 is inhaled into by the port of in the port shown in accompanying drawing, and the medium simultaneously transmitted is forced out by another port.
Rotor 5 is arranged in housing 3 by following axle in the mode that can drive rotatably usually, and this axle is arranged with one heart relative to medial axis 11 and connected in a fixed manner according to the rotation of rotor 5.
Present below by way of example, rotor is driven with the counter clockwise direction according to arrow 33.When the rotor rotates, the outer end of blade 17 is pressed against lift profile 27 in a sealing manner.During the rotary motion of rotor 5, be formed in the transfer chamber 19 between vertical blade and the blade on the left of this vertical blade and expand its volume along the direction of arrow 33.Transfer chamber 21 can be seen in the left side of intermediate blade, the volume of transfer chamber 21 is greater than the volume of transfer chamber 19, this is because, during the rotary motion of rotor 5, blade is outwards advanced along lift profile 27, therefore causes transfer chamber 21 larger with transfer chamber 19 phase specific volume.
Because lift profile 27 is formed symmetrically relative to horizontal radial line 15, blade, after reaching in as accompanying drawing the horizontal position reproduced, moves in the inside of groove 9 by lift profile 27, the transfer chamber volume between two continuous blades is reduced.Port is provided with symmetrically, not shown herein relative to port 29.
Because the volume of transfer chamber 19 expands during the rotary motion of rotor 5, as long as port 29 is connected to transfer chamber in the mode of fluid, medium is sucked from leaf type pump 1 by port 29.Further rotate between moving period in the direction along arrow 33, the blade be positioned on angular bisector reaches the left hand edge 37 of port 29, and transfer chamber 21 is connected with not having fluid between port.When reducing in the process further rotated at rotor of the volume of transfer chamber 21, medium is acted on by pressure and herein unshowned port is discharged from described port under the effect of the pressure, and this port is arranged about horizontal radial line 15 symmetrically relative to port 29.
Correspondingly, identical for port 31 situation, the medium of pressurization is forced out this port 31 from transfer chamber.
The fundamental function of leaf type pump described herein is known and does not therefore carry out herein anyly describing in more detail.
Accompanying drawing is clearly shown that port 29 has outward edge 39 and port 31 has outward edge 41.Outward edge 39 and outward edge 41 are towards lift profile 27 and be arranged to and lift profile 27 x in a distance.Port 29 is hidden by the side surface of rotor 5 in this article with the inward flange relative with outward edge 41 with outward edge 39 respectively of port 31, as indicated by a dotted line.
The medium transmitted by leaf type pump 1 is: water, alcohol---such as ethanol, ammonia or other organic liquids.Also can be the mixture of described material herein.Again by proportion higher than the oiling agent additional mixing of the proportion of all the other compositions of medium in this medium.
Observation side surface 25, is clear that the outward edge 39 of port 29 and port 31 and outward edge 41 roughly follow lift profile 27 in some region, but does not have contacting travel profile 27 because of distance x.When the rotor 5 with blade 17 being set to the operation period rotation at leaf type pump 1, produce centrifugal force, due to centrifugal force, the most hyperbaric composition that has of institute's transmission medium starts to be pressed against lift profile 27.Therefore, it is reported and form oiling agent ring on the internal surface of lift profile 27, the thickness of described oiling agent ring and outward edge 39, outward edge 41 are corresponding apart from the distance x of lift profile 27.Therefore, just in the region of lift profile 27, forming lubricant film---this lubricant film only comprises the water of very little share, alcohol or ammonia, in the region that the outer end making the lubrication of oiling agent be applied to blade 17 exactly contacts with lift profile 27.Outward edge 41 due to port 31 is arranged to and lift profile 27 distance x, and oiling agent is not discharged from port 31, because it laterally can not overflow on edge.The a part of oiling agent higher than distance x be only deposited in oiling agent ring can be overflowed from port 31.Therefore, when leaf type pump is in operation, there is the enrichment of oiling agent directly on lift profile 27.Thus the medium of overflowing from port 31 is lower in the lubricant and is therefore particularly suitable for being supplied to heat recovering device.
Because the outward edge 39 of port 29 is apart from the distance x of lift profile 27, oiling agent can not be overflowed from port 29.
In addition, preferably, there is following setting: wherein, the external frame 43 of rotor 5 maintains the distance y apart from Internal periphery 27.Why this configuration is preferably because therefore the oiling agent ring be formed on Internal periphery 27 is not damaged by rotor 5 when leaf type pump 1 is in operation.If external frame 23 contacts Internal periphery 27, then oiling agent ring will completely displacement and must contact in the outer end by blade with rear region in re-establish.
Thus, preferably there is following setting: wherein, distance y is corresponding with distance x.Especially, preferably two distance x and y are equally formed.
This configuration ensure that when leaf type pump 1 is in operation, and Internal periphery 27 is formed stable oiling agent ring, almost 100% forming by oiling agent of this oiling agent ring.The outer end of blade 17 thus move on lift profile 27 in oiling agent ring, makes wearing and tearing to be reduced to minimum.
Port 29 and port 31 ensure that the specific thicknesses of oiling agent ring apart from the distance x of lift profile 27, make to keep away non-lubricating with the highest possible probability and interrupt.If following situation, all the more so: namely, the external frame 43 of rotor 5 is arranged to and Internal periphery 27 distance y, and oiling agent ring can be formed on whole Internal periphery 27 continuously.
Become and be apparent that, distance x should preferably in the scope of 0.1mm to 2mm, especially in the scope of 0.3mm to 1.0mm.The distance x of 1mm is particularly preferred.Be suitable in addition: y >=x herein.
Oiling agent share in the medium transmitted by leaf type pump 1 provide not only the advantage of the lubrication of improvement, but also provides the outer end of blade---that is leaf head---and the interstitial volume loss between Internal periphery 27 and be reduced to another minimum advantage.This is because the viscosity Comparatively speaking higher with all the other compositions of medium of oiling agent causes.
