Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a series of semi-hermetic refrigeration high-efficiency compressors. Background technique [0002] At present, the compressor is a driven fluid machine that lifts low-pressure gas into high-pressure gas. It is the heart of the refrigeration system. It inhales low-temperature and low-pressure refrigerant gas from the suction pipe, drives the piston to compress it through the operation of the motor, and discharges high-temperature and high-pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle, thereby realizing Compression→condensation (heat release)→expansion→evaporation (heat absorption) refrigeration cycle, most existing compressor manufacturers have production starters and thermal protectors, but purchase them from the market according to needs, and the overall structure is not compact.
