Description

The carbon dioxide spherical expansion compressor capable

Technical field

The utility model relates to a kind of compressor, particularly relates to a kind of CO of being applicable to ₂The spherical expansion compressor capable of working medium.

Background technique

In the refrigeration refrigerator field of air conditioning, because conventional refrigerants fluorine Lyons R11, R12, R22 are to destruction and other harm of atmospheric ozone layer, since last century 80 to the nineties, the whole world begins to limit the use of these refrigerants, the substitute products that use in a large number at present are R134a, R600a, R407c, R410A etc., these alternatives also are as cambic, because they also have in various degree harm to atmosphere, for example increase the weight of room temperature effect etc.Since the nineties in last century, scientist has just begun the research to the pure natural refrigeration agent, wherein CO ₂, NH ₃, H ₂O is considered to final alternative, wherein with CO ₂The most important, because CO ₂Many good characteristics and good physical property are arranged: (1) need not produce specially, utilizes industry byproduct to get final product, and user cost is low.(2) refrigerating effect per unit swept volume is big, is R12, R22 5-8 times, and the compressor operating volume can be very little.(3) kinematical viscosity is low, and flow losses are little.(4) adiabatic index height, compression ratio is low.(5) good with lubricant oil and common used material adaptability.(6) safe in utilization.Each big industrial state of the world has all dropped into lot of manpower and material resources to CO over more than 10 year ₂The refrigeration technology of medium is carried out deep application study, and wherein existing procucts listing aspect car air conditioner, household water heater has also obtained certain progress for the application on domestic air conditioning, the refrigerator.

Because CO ₂Must adopt as refrigeration agent and to stride critical cycle operation and just can reach high efficiency, thus the working pressure height, be conventional refrigerants 5-10 doubly; Simultaneously because CO ₂The best effort scheme require multistage compression, with one-level expansion recovery section expansion work, just can make its efficient be higher than traditional working medium simultaneously.These characteristics are to CO ₂The compressor decompressor has proposed new requirement.A large amount of studies show that scroll compressor, rolling piston compressor, sliding-vane compressor are used for CO ₂Efficient is not high during compressor, mainly is a series of problems brought of leaking, and the company that abroad has adopts swing-rotor type (distortion of rolling-piston-type) to be used for CO ₂Circulation, but can not be called extraordinary scheme, can only be a kind of relatively selection under the prior art condition.Really be used for CO at present reliably ₂It is reciprocating piston type that circuit is known as, and it is by the CO that is applied to of success with its sealing reliably ₂In the circulation.But the self-defect of Reciprocting piston compressor has limited its using scope greatly, and is many as air valve, vibrations are big, frequency conversion difference etc.If what is more important adopts CO ₂Optimal economic circulation, multistage compression are expanded (being generally secondary compression one-level expands), more than various compressors all face a problem, must finish multistage compression and expansion by a plurality of clutch release slave cylinders exactly.Therefore at CO ₂The compression refrigeration field, the R and D of effective integrated expansion compressor capable become worldwide focus and advanced subject.

I apply for the invention disclosed patent, patent name is a kind of variable capacity mechanism that is used for compressor, the patent No. 03114505.1, this is a kind of brand-new compressor arrangement, few, the no air valve of this compressor movement parts, the vibration little, its sealability is better than sliding vane, rolling-piston-type, eddy type, swing-rotor type etc. greatly, it has two working rooms of alternate, can realize the one-level compression, expand, still can better not be applicable to CO fully but its structure still can not realize multistage compression ₂Circulation.

Above-mentioned four each embodiments of embodiment also have following common ground:

One, the V1 of working room 201, the V3 of working room 203, the V5 of working room 205, the V7 of working room 207, the V9 of working room 209 are the greatest limit volume conditions in each example structure sectional drawing, and the V2 of working room 202, the V4 of working room 204, the V6 of working room 206, the V8 of working room 208, the V10 of working room 210 are the least limit volume conditions in each example structure sectional drawing;

Two, the rotation by piston realizes intake and exhaust control, and the principle of gas port and intake and exhaust channel setting is that when intake and exhaust channel needed exhaust or air inlet in each working room, the air flue in this working room was communicated with corresponding intake and exhaust channel.

Three, the axis of above-mentioned piston shaft and turntable shaft and main shaft 8 centre of sphere by spherical inner chamber all, and the axis of piston shaft and turntable shaft forms identical angle α with the axis of main shaft 8; The cylinder cap and the mold joint of cylinder body are placed on the plane of passing through the spherical inner chamber centre of sphere vertical with piston shaft convenient processing and assembling;

Four, turning to of main shaft 8 is 8 directions from cylinder cap along main shaft, and main shaft 8 clockwise rotates;

Five, the erection sequence of cylinder hinge is, connects piston pin boss and rotating disk key seat with centrepin 4 earlier, connects piston hinge support with positioning screwn 12 at the two ends of piston pin boss again;

Six, on main shaft 8 and the contacted rotation surface of cylinder body, permanent-magnet material is set respectively, on cylinder body and rubbing surface that main shaft 8 contacts, be bumped into a permanent magnet 11, Fig. 6 is a M-M sectional view among first example structure sectional drawing Fig. 2, the M-M sectional view is identical with embodiment one in other example structure sectional drawing, can be with reference to Fig. 6; Identical in the corresponding polarity that also is bumped into the relative face of permanent magnet 11, two permanent magnets of main shaft 8 counterparts, near the time repel mutually; utilize the identical repulsive force of polarity; stop when preventing piston axis and rotating disk dead in line, can not shut down, utilize magnetic force to push main shaft 8 open several angle in this position.Because in this position is a dead center position, if just shut down in this position, start and just might change motionless next time; Figure 18 is the main shaft plan view.

Use permanent-magnet material for the parking of anti-locking mechanism dead center position, also can use other common structure device in the reality, as cam structure parking limit stoper; No matter be permanent-magnet material limit stoper or cam structure limit stoper, can be arranged in cylinder body space in addition, can be installed between rotor and the stator as permanent-magnet material formula limit stoper.

Seven, among above-mentioned four kinds of embodiments, the circulation of lubricating oil path can be to introduce from main shaft, goes out from piston shaft, also can be to introduce from piston shaft, brings out from main shaft.
