Semi-hermetic refrigeration compressor

Abstract

The invention relates to a semi-hermetic refrigeration compressor, which comprises a shell, a motor, a cylinder, a piston, control equipment and a cooling system, wherein the control equipment comprises a starter and a thermal protector, and a suction line valve is arranged at one end of the shell; a low-pressure screw plug is arranged on the suction line valve, and an oil filling port is formed in the cylinder; an oil level lens is arranged at the lower end of the oil filling port, and an oil heater jointis arranged at one side of the oil level lens; a high-pressure screw plug is also arranged on the cylinder, and a discharge line valve is arranged at one side of the high-pressure screw plug. After the whole equipment assembly is finished, the compressor has the advantages of high performance, advanced technical indicators, reasonable structure, small size, light weight, low noise, high degree of universality of parts, and smooth operation; the motor adopts inhaled steam cooling, the overload capacity is large, and the durability is high; the service life of the compressor is 50,000 hours, the mean running time without failures is 12,000 hours, and the reliability is high. The product can be widely matched with various climatic environment equipment, refrigeration and freezing equipment, ice cream machines and other cold drink food machinery equipment.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a series of semi-hermetic refrigeration economical 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.
