Cylinder body structure of compressor

Abstract

The invention relates to a cylinder body structure of a compressor. The upper part of the cylinder body base is provided with a connecting seat, a crankshaft hole, a first-level high-pressure buffering chamber and a second-level high-pressure buffering chamber. The end face of the connecting seat is provided with a piston hole, the connecting seat is coaxially and fixedly arranged with a cylinder cover through a valve plate, and an inspiration muffler is fixedly arranged on the cylinder cover, wherein (1) the end face of the connecting seat is provided with a through hole and a second-level high-pressure chamber air vent respectively, and the through hole is communicated with the second-level high-pressure air vent through a groove formed on the end face of the connecting seat; (2) the valve plate is provided with a first-level high-pressure vent hole, an air suction hole and an exhaust hole; and (3) the air suction hole airtightly covered with an air suction hole valve sheet, and the air exhaust hole is airtightly covered with an air exhaust hole valve sheet. The cylinder body structure has a scientific and reasonable structural design, and high-pressure gas is effectively buffered in the structure to greatly reduce gas pulsation and reduce the overall noises of the compressor, thus the cylinder body structure can keep good dynamic balance.

Description

technical field [0001] The invention belongs to the field of compressors, in particular to a compressor cylinder structure. Background technique [0002] The compressor is widely used in the field of refrigeration appliances, and is the heart of the refrigeration system. It sucks 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. The agent gas provides power for the refrigeration cycle, thereby realizing the refrigeration cycle of compression→condensation→expansion→evaporation (heat absorption). A compressor generally consists of a housing, motor, cylinder, piston, control equipment (starter and thermal protector) and a cooling system. At present, the noise emitted by the refrigerator when it is running is mainly produced by the high-pressure gas in the compressor, and the main method to solve the no...

AI Technical Summary

Problems solved by technology

At present, the noise emitted by the refrigerator when it is running is mainly produced by the high-pressure gas in the compressor, and the main method to solve the noise problem of the refrigerator compressor is to set a high-pressure buffer chamber on the cylinder body, and the most used one is to install it on the cylinder body A long high-pressure buffer chamber is made; the other is that two high-pressure buffer chambers are formed on the cylinder, and the two high-pressure buffer chambers are set on one side of the cylinder piston, and they communicate with each other. Although the setting of the high-pressure buffer chamber can reduce noise, it can no longer meet the requirements of today's technological development.
