Horizontal type rotating compressor for electric car air conditioner and work method

Abstract

The invention discloses a horizontal type rotating compressor for an electric car air conditioner and a work method. The compressor comprises a shell, a controller arranged on the outer side of the shell, a motor, a pump body, a low-pressure air suction pipe and a high-pressure exhaust cyclone separator, the motor and the pump body are arranged in the shell, and the low-pressure air suction pipe and the high-pressure exhaust cyclone separator are distributed on the shell. The pump body adopts a non-circular air cylinder as a supporting part, the supporting part and the annular end face in themiddle segment of the shell are sealed and fixed, the interior of the compressor shell is divided into a low-pressure cavity and a high-pressure cavity, a motor is located in the low-pressure cavity,an oil pond is located in the high-pressure cavity, the radial extending part of an auxiliary bearing of the pump body is provided with an oil supply hole, the auxiliary bearing and crankshaft eccentric portions are provided with spiral oil grooves, the air suction and exhaust pressure difference is used for supplying the lubricating oil into an auxiliary bearing unloading oil groove from the oilpond, and through the spiral oil grooves, the lubricating oil is supplied to a main bearing; and the compressor oil seal amount is reduced, the oil level stability is maintained, the oil supply problem of an existing horizontal type rotating compressor can be solved, and meanwhile, air suction can be used for cooling the motor and the controller.

Description

technical field [0001] The invention relates to a compressor for an electric vehicle air conditioner, in particular to a horizontal rotary compressor for an electric vehicle air conditioner and a working method. Background technique [0002] In recent years, more and more people pay more and more attention to the problem of automobile exhaust pollution. The replacement of fuel vehicles by electric vehicles has become the main trend of the future development of the automobile industry. In the past period of time, although the electric vehicle industry has developed rapidly, the energy consumption problem of the air conditioning system has not been effectively resolved. [0003] The key to solving the above problems is to develop a reliable, energy-saving and efficient air-conditioning compressor for electric vehicles. The existing air-conditioning compressors for electric vehicles are mainly scroll compressors. However, the development cycle of electric scroll compressors is...
