Non-return device for refrigerator compressor performance test equipment

Abstract

The invention discloses a non-return device for refrigerator compressor performance test equipment. The non-return device comprises a non-return mechanism and a support mechanism, wherein the support mechanism is connected with the non-return mechanism and supports and matches with the non-return mechanism to limit springback of a refrigerator compressor; the non-return mechanism comprises a U-shaped base, a pin shaft penetrating through the part close to the top end of the U-shaped base and a non-return block rotationally fixed on the U-shaped base through the pin shaft, and the starting height of the non-return block in a rotating process is larger than that of the top end plane of the U-shaped base; a torsional spring is in embedded connection between the non-return block and the U-shaped base; a cushion block is mounted in the position close to the bottom end of the U-shaped base. The support mechanism comprises a mounting rack conveniently fixed on a mounting platform and an adjusting rack which is integrated and fixedly connected with the mounting rack and can move on the mounting rack up and down; the U-shaped base is movably fixed on the adjusting rack. The device is simple in structure, high in adjusting speed, very high in universality and low in manufacturing cost, and can better meet the requirement of accurate positioning of the refrigerator compressor before an energization performance test.

Description

technical field [0001] The invention belongs to the technical field of performance testing of refrigerator compressors, and in particular relates to a non-return 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 a...
