Description

Oil-gas separated-type air condition compressor

Technical field

The utility model belongs to air condition compressor field, is specifically related to the oil-gas separated-type air condition compressor of rotator type, not only can be applied on single-rotor compressor, can also be applied on many rotor compressors.

Background technique

Rotor-type compressor is a kind of volume type rotary compressor, the change of cylinder body swept volume, relies on the rotation of an eccentric in cylinder to realize.Cylinder body is made up of cylinder body body and end cover.Eccentric comprises main shaft, eccentric rotor and revolving sleeve, main shaft and eccentric rotor one-body molded, revolving sleeve is set in the periphery of eccentric rotor to form this eccentric.Under working state, eccentric and cylinder body body inscribe are also all the time along cylinder body inner body wall rolling formation moon teeth cavity that works.Slide damper leans on the active force of spring to make the outer circumferential face close contact all the time of its end and revolving sleeve, work moon teeth cavity is divided into suction chamber and discharge side two cavitys.Slide damper is reciprocating in chute with the rolling of revolving sleeve, end cover is installed in cylinder body body two ends, the cylinder body volume forming and close is contacted with cylinder body inner body wall, revolving sleeve, slide damper, i.e. element volume, its volume size changes with angle of rotor, in volume, the pressure of gas then changes with the size of element volume, thus completes the working procedure of compressor.

Rotor-type compressor is widely applied on air conditioner because of advantages such as its structure are simple, with low cost, and its performance directly affects the efficiency of air conditioner.

Adopt two kinds of lubricating systems to lubricate when existing rotor-type compressor uses on air conditioner simultaneously, the first lubricating system is the lubrication and the sealing that are realized eccentric rotor, up and down end cap and slide damper by oil pump conveying lubricant oil, but adopt this lubricating system, have only between revolving sleeve outer circumferential face and cylinder body inner body wall and do not have lubricant oil access way thus cannot realize independent lubricating and the sealing of lubricant oil.Therefore, lubrication between revolving sleeve outer circumferential face and cylinder body inner body wall and sealing must be realized by the mixing of the second lubricating system and lubricant oil and refrigeration agent.

Although rotor-type compressor adopts above-mentioned the second lubricating system can solve lubrication between revolving sleeve outer circumferential face and cylinder body inner body wall and sealing problem, but use on air conditioner and also there is following shortcoming: (1), lubricant oil are blended in compresser cylinder and take compressor cavity element volume, because compressor element volume is fixing, comparatively speaking, the just corresponding minimizing of space shared by refrigeration agent, for same compressor, its refrigeration agent discharge capacity just reduces; Compressor temperature is higher, and lubrication oil gasification is faster, and shared space is also larger, and it is more that dragged lubricant enters pipeline; (2), lubricant oil has viscosity, compressor operationally, because the existence of lubricant oil in the damping virtually increasing rotor turns, thus will increase the power consumption of compressor; (3), lubricant oil and refrigeration agent mixed flow in air-conditioner hose, lubricant oil can be caused like this to be attached to copper pipe inwall, form oil film thermal-protective coating, refrigeration agent needs just can carry out heat exchange through oil film thermal-protective coating, therefore greatly will affect the heat exchange of refrigeration agent, thus reduce the efficiency of whole system.
