Abstract

The invention discloses an automobile air conditioner compressor valve group air tightness detection device comprising a support plate. A push rod is arranged on the left side of the upper surface ofthe support plate. A lithium battery pack and a vacuum pump are arranged on the upper surface of the support plate in sequence from left to right. Support rods are arranged around the upper surface ofthe support plate. A holding plate is arranged on the upper end faces of the support rods. A positioning plate, positioning columns, a single chip microcomputer, a hollow detection box and a displayare arranged on the upper surface of the holding plate in sequence from left to right. The positioning columns are sleeved with pressure plates. The automobile air conditioner compressor valve group air tightness detection device has a simple structure, is convenient to operate, occupies little space in use, and can easily detect the air tightness of an automobile air conditioner compressor valvegroup. Through locking universal wheels and the push rod, the device can be easily moved. The position of a detected part can be fixed through the pressure plates. The display enables people to have an intuitive understanding of the air tightness of the detected part.

Description

technical field [0001] The invention relates to the technical field of auto parts detection, in particular to an air tightness detection device for an automobile air-conditioning compressor valve group. Background technique [0002] The main function of the automobile air-conditioning compressor is to supply the refrigerant to the entire refrigeration cycle system. The refrigerant supply function of the refrigeration compressor mainly consists of two working processes, one is the suction process, the other is the exhaust process, the suction process and the exhaust process It is mainly realized through the reciprocating motion of the piston of the refrigeration compressor. In order to realize the two processes, the valve plate assembly must be included for cooperation. The valve plate assembly is composed of a suction valve plate, a valve plate and an exhaust valve plate. The valve plate assembly is mainly It provides a function of controlling the gas flow direction, because...
