Automobile air conditioner compressor valve group air tightness detection device

Abstract

The invention discloses an air tightness detection device for a valve group of an automobile air-conditioning compressor, which comprises a support plate, a push rod is arranged on the left side of the upper surface of the support plate, and a lithium battery pack and a lithium battery pack are arranged on the upper surface of the support plate from left to right in sequence. For a vacuum pump, support rods are provided around the upper surface of the support plate, and a support plate is provided on the upper end surface of the support rod. The upper surface of the support plate is sequentially provided with a positioning plate, a positioning column, a single-chip microcomputer, a hollow detection box and a display screen from left to right. The positioning column is sleeved with a pressure plate. The air-tightness detection device for the valve group of the automobile air-conditioning compressor has a simple structure, is easy to operate, and takes up little space when used. It can easily detect the air-tightness of the valve group of the automobile air-conditioning compressor. , the use of the locking universal wheel combined with the push rod makes the present invention can move the position very conveniently, the position of the part under test can be fixed through the pressure plate, and the setting of the display screen allows people to intuitively check the airtightness of the part under test sex to understand.

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...
