Description

Technical Field

[0001] The utility model relates to the technical field of compressors, in particular to a protective component of a compressor. Background Art

[0002] A compressor is a driven fluid machine that boosts low-pressure gas to high-pressure gas. It is the heart of the refrigeration system. It inhales low-temperature, low-pressure refrigerant gas from the suction pipe, compresses it by driving the piston through the motor, and then discharges high-temperature, high-pressure refrigerant gas to the exhaust pipe, providing power for the refrigeration cycle. Compressors are divided into piston compressors, screw compressors, centrifugal compressors and linear compressors.

[0003] For example, application number CN202022808117.6. The utility model relates to a compressor reservoir and a compressor, the compressor comprising a compressor body, the compressor reservoir being arranged outside the compressor body, comprising a reservoir body, a first connecting pipe and a second connecting pipe; one end of the second connecting pipe is connected to the bottom of the reservoir body, and the other end is arranged to extend around the outer surface of the compressor body and is connected to the compressor body. When the gaseous refrigerant enters the compressor body through the reservoir, due to the high temperature generated by the compressor body during operation, the residual liquid or wet refrigerant in the second connecting pipe caused by insufficient heat exchange of the evaporator can be evaporated by heat, and then become a gaseous refrigerant and enter the compressor body, which effectively avoids the problem of liquid compression or wet compression due to the presence of liquid or wet refrigerant, resulting in large power fluctuations in the compressor system and affecting the reliability of the compressor.

[0004] Based on the search of the above patents and in combination with the equipment in the prior art, it is found that although the above equipment can solve the problem of insufficient refrigerant heat exchange in small cooling and heating systems due to the small size of the evaporator, liquid or wet refrigerant may easily enter the compressor. At this time, there is liquid compression or wet compression in the compression process of the compressor, resulting in large fluctuations in system power, which in turn affects the reliability of the compressor. However, during use, it is exposed to the external environment for a long time, and the main body is easily damaged due to accidental collisions. At the same time, dust entering the compressor will reduce its service life. Utility Model Content
