compressor

Abstract

The invention discloses a compressor, comprising: a housing, a cylinder assembly, a main bearing, an auxiliary bearing, a frame, a crankshaft, a dynamic seal and a transmission mechanism, an oil pool is provided in the housing; the cylinder assembly is arranged in the housing, and the cylinder assembly It includes at least one cylinder; the frame is arranged on the side away from the cylinder assembly of the main bearing, and the frame is sealed with the casing and the main bearing and defines an accommodation space; one end of the crankshaft passes through the main bearing and extends into the cylinder, and the crankshaft The other end extends out of the accommodation space; the dynamic seal is arranged between the main bearing and the crankshaft to seal the gap between the main bearing and the crankshaft; the transmission mechanism is arranged at the other end of the crankshaft to drive the crankshaft to rotate. According to the compressor of the present invention, the sealing performance of the compressor is improved, and the difficult sealing problem of the traditional semi-hermetic compressor is solved, thereby reducing the volume and weight of the compressor, and improving the energy efficiency and reliability of the compressor Moreover, the structure is simple and easy to assemble.

Description

Technical field[0001]The present invention relates to the technical field of compressors, in particular to a compressor.Background technique[0002]In the related art, compressors, such as those used in air conditioners, have relatively high pressure, and it is difficult to realize a semi-hermetic compressor that separates the compression mechanism from the transmission mechanism. The main reason is that the discharged high-pressure refrigerant refrigerant oil easily leaks to the low-pressure external environment. If it comes out, it will cause the refrigerant leakage of the air-conditioning system and affect the refrigeration effect. The leakage of the refrigerating oil will easily cause the reliability of the compressor to decrease. Therefore, the structure of the air-conditioning compressor is basically a fully enclosed structure.[0003]However, the hermetic compressor needs electricity to drive. In some occasions, for example, the car air conditioner compressor needs to convert the...

Problems solved by technology

[0002] In related technologies, the pressure of compressors such as those used in air conditioners is relatively high, and it is difficult to realize a semi-hermetic compressor that separates the compression mechanism from the transmission mechanism. The main reason is that the exhausted high-pressure refrigerant and refrigerated oil are easy to leak into the low-pressure external environment. Leakage of the refrigerant in the air-conditioning system will affect the cooling effect, and the leakage of refrigerated oil will easily lead to a decrease in the reliability of the compressor. Therefore, the structure of the air-conditioning compressor is basically a fully enclosed structure.

[0003] However, fully enclosed compressors need electricity to drive. In some cases, such as automotive air-conditioning compressors, the kinetic energy of the engine needs to be converted into electrical energy, and then the electrical energy drives the motor of the compressor to run. Due to the continuous conversion of energy, the energy utilization rate not tall

In addition, air-conditioning compressors generally use rotary compressors, and the sealing problem of rotary compressors is difficult to solve. If the sealing problem of semi-hermetic compressors is solved, the mature production process of rotary compressors will bring new opportunities to the market for semi-hermetic compressors. growth point
