Ventilation device for refrigerator compressor performance test equipment

Abstract

The invention discloses a ventilation device for refrigerator compressor performance testing equipment. The ventilation device includes a ventilation mechanism, a driving device connected to the ventilation mechanism and driving the ventilation mechanism to communicate with the intake pipe of a refrigerator compressor, and supporting and cooperating with the ventilation mechanism and the driving device to operate. support mechanism. The ventilation mechanism includes an air passage transition block, a cooling pipe and an air joint forming an air intake passage; the driving device is set as a cylinder, and the cylinder is fixedly connected with the air passage transition block, and the cylinder drives the air passage transition block, Simultaneously drive the cooling pipe and the air joint to connect with the air intake pipe of the refrigerator compressor. The support mechanism includes a mounting frame and a fixed adjustment mechanism connecting the mounting frame and the ventilation mechanism. The ventilation device can inflate and protect the refrigerator compressor during the power-on performance test, has a simple structure and fast adjustment speed, is suitable for various types of refrigerator compressors, has high versatility and low manufacturing cost.

Description

technical field [0001] The invention belongs to the technical field of performance testing of refrigerator compressors, in particular to a ventilation device for performance testing equipment of refrigerator compressors. Background technique [0002] The compressor 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. In this way, a refrigeration cycle of compression→condensation→expansion→evaporation (heat absorption) is realized. A compressor generally consists of a housing, motor, cylinder, piston, control equipment (starter and thermal protector) and a cooling system. There are two cooling methods: oil cooling and natural cooling. General household refrigerator compressors use single-phase alternating ...

AI Technical Summary

Problems solved by technology

At present, after the production and assembly of compressors, most manufacturers of compressors are often unable to test the performance of the compressors due to the limitation of factory production conditions, or are limited to the operation test of their mechanical properties. , which makes the compressor have a certain risk in the operation reliability of the actual application
