Compressor

Abstract

The invention discloses a compressor. The compressor comprises a shell, a gas inlet end, a gas outlet end, a motor, a cylinder, a gas storage tank and a starting device and further comprises a silencer, wherein the silencer is arranged at the gas inlet end of the compressor, the starting device comprises a starting circuit, and the starting circuit comprises a starting capacitor and a PTC thermistor which are connected; and the other end of the starting capacitor is connected to a secondary winding of a CSIR, the other end of the PTC thermistor is connected to a main winding of the CSIR, and the CSIR is connected to a thermal protector through a motor common wire. According to the technical scheme, the PTC thermistor and the starting capacitor are combined, the starting current is reduced,meanwhile, the starting torque of the compressor is increased, the requirement for the starting voltage of the compressor is reduced, the starting and working stability of the compressor is improved,gas inlet noise caused by pressure pulsation of airflow in a gas inlet pipe is greatly eliminated through the silencer, the working environment is optimized, and the noise pollution is reduced.

Description

technical field [0001] The invention relates to the technical field of refrigerator refrigeration, in particular to a compressor. Background technique [0002] A compressor is a driven fluid machine that elevates low-pressure gas to high-pressure gas, and 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. The noise problem of refrigeration compressors is also an important indicator to measure their overall performance. Compressor intake noise is caused by pressure pulsations of the airflow in the intake manifold. The fundamental frequency of the intake noise is the same as the gas pulsation frequency in the intake pipe, which is related to the speed of the compressor. Contents of the invention [000...

AI Technical Summary

Problems solved by technology

[0003] The present invention mainly solves the technical problem that the current fluctuation of the original motor is too large when the motor is started, and the suction noise is large during the working process. At the same time, the starting torque of the compressor is increased, the demand for the starting voltage of the compressor is reduced, the stability of the starting and working of the compressor is improved, the intake noise caused by the pressure pulsation of the air flow in the intake pipe is greatly eliminated through the muffler, and the work is optimized environment, reducing noise pollution
