Compressor

Abstract

The invention discloses a compressor. The compressor comprises a shell cover, a shell, a machine frame, an orbiting scroll, a static scroll, a crankshaft driving mechanism, a separation structure, anoil pump, a first oil return pipe and a second oil return pipe; the shell cover and the shell are buckled to form an accommodating space; the maching frame is arranged in the shell; the orbiting scroll abuts against the machine frame, and a lubricating space is formed between the orbiting scroll and the machine frame; the crankshaft driving mechanism is connected with the orbiting scroll; an oil storage space is formed between the separation structure and the accommodating space; the oil pump is arranged at the lower end of the crankshaft driving mechanism; the first oil return pipe is communicated with the oil storage space; the second oil return pipe is communicated with the lubricating space, and the second oil return pipe is connected with the first oil return pipe; and an oil supply pipeline is arranged in the crankshaft driving mechanism, the lower end of the oil supply pipeline is connected with the oil pump, and the upper end of the oil supply pipeline is communicated with thelubricating space. Through the compressor, the oil circulation rate of the compressor is reduced, the working reliability of the compressor is improved, the oil circulation rate of an air conditioningsystem is reduced, and the heat exchange efficiency of the air conditioning system is improved.

Description

Technical field[0001]The invention relates to the technical field of compressors, in particular to a compressor.Background technique[0002]Compressors are mostly used in the refrigerant compression process of air-conditioning systems in automobiles. The most common is scroll compressors. The mixture of refrigerant and lubricating oil is often involved in the compression cycle. The refrigerant is used as the temperature of the air-conditioning system. During the adjustment work, lubricating oil is used to reduce friction, so that the wear of the compressor, especially the crankshaft and the movable scroll, is reduced. However, due to the influence of heat transfer and other factors, if the ratio of oil in the mixture of refrigerant and lubricating oil is too high, it will often affect the working efficiency of the air conditioner, and the lubrication effect of the compressor parts depends heavily on the oil return of the air conditioning system. Effectively, once the system returns po...

However, due to the influence of factors such as heat transfer, if the ratio of oil in the mixture cycle of refrigerant and lubricating oil is too high, the working efficiency of the air conditioner will often be affected, and the lubrication effect of the compressor parts is heavily dependent on the return oil of the air conditioner system Effect, once the oil return of the system is poor, it will cause the compressor to be damaged due to poor lubrication
