A performance and life evaluation device for refrigeration compressor valve plate

Abstract

The invention discloses a refrigeration compressor valve block performance and service life evaluation device. The device comprises a mechanical system and a measurement and control system; the mechanical system comprises a rack which is fixedly provided with a valve block testing mechanism; a pressure gage, a pressure gage hand valve and the like are fixed to a panel of the rack, and a precisionpressure regulator valve and an air inlet hand valve are fixedly arranged on the table top of the rack; an electrical system mounting plate is arranged in the bottom space of the rack; the valve blocktesting mechanism adopts a multi-station parallel mechanism, an air source filter, regulator and lubricator combination is connected with the air inlet hand valve, the precision pressure regulator valve, a high-frequency solenoid valve and a pressure sensor of all stations in sequence, the high-frequency solenoid valve is connected with a valve block base, a valve plate is installed on the valveblock base, the valve plate is used for installing a tested valve block, and an optical fiber sensor is arranged in front of the tested valve block. The device has the advantages that non-contact measurement can be conducted on the valve block lift range and movement frequency, automatic judgement on valve block failures is achieved, relations among the valve block movement times, the valve blockexciting loads and the lift range are recorded, and the device is convenient to operate and accurate in measurement.

Description

technical field [0001] The invention relates to the technical field of manufacturing test equipment for refrigeration compressors, in particular to a device for evaluating the performance and life of a valve plate of a refrigeration compressor. Background technique [0002] With the improvement of people's quality of life and consumption level, refrigerators, air conditioners and other refrigeration appliances have become indispensable household appliances in family life. At the same time, customers have higher and higher requirements on the performance, safety and life of household appliances. The core component of the refrigeration system - the compressor is the key not only in terms of technology, design, manufacturing, but also in terms of cost, performance, and life. Improvement is important. The valve plate is a key part of the refrigeration compressor. The opening and closing of the valve plate controls the four processes of compressor suction, compression, exhaust, ...
