Problems solved by technology
The existing back pressure technical solutions generally provide high pressure for the back pressure of the slider. Although it can ensure that the head of the slider is in constant contact with the inner wall of the cylinder, during the suction and compression stages, a large back pressure will cause the head of the slider to contact the cylinder. The large contact force and frictional resistance of the inner wall will eventually lead to high power consumption of the compressor, and even cause abnormal wear of the compressor, which will affect the performance and reliability of the compressor

The invention relates to a compressor slip sheet backpressure structure, a compressor with the backpressure structure and an air-conditioner with the backpressure structure. A backpressure oil cavity is formed in one end of a slip sheet, and the backpressure structure comprises a pressure adjusting structure arranged between an oil pool cavity and the backpressure oil cavity. By means of the compressor slip sheet backpressure structure, as the pressure adjusting structure is arranged, the pressure of oil entering the backpressure oil cavity can be adjusted, frictional resistance between the head of the slip sheet and the inner wall of an air cylinder can be effectively reduced, the working performance of the compressor is optimized, and the service life of the compressor is prolonged.
Description
technical field [0001] The invention relates to the technical field of compressors, in particular to a compressor sliding vane back pressure structure and a compressor and an air conditioner having the same. Background technique [0002] For rotary vane compressors, when the rotor rotates, the vanes in the vane groove will be pushed out by the centrifugal force and the back pressure generated by the high-pressure oil to come into close contact with the inner surface of the cylinder, and start to compress the gas. In order to ensure the normal operation of the compressor, high-pressure oil is generally used for the back pressure of the slide vane to provide sufficient back pressure for the slide vane, so as to prevent insufficient back pressure when the front and rear chambers of the slide vane head are at exhaust pressure, resulting in the failure of the slide vane head. If the part is separated from the inner wall of the cylinder, there will be problems such as leakage and ...
