Air tightness detection equipment for double-screw refrigeration compressor

Abstract

The invention relates to the technical field of refrigeration compressor air tightness detection, and further discloses air tightness detection equipment for the double-screw refrigeration compressor.The equipment comprises a shell. Airtight plates are fixedly connected to the upper side and the lower side of the shell. The side, away from the shell, of the airtight plate is fixedly connected with a gas storage groove. The ends, away from the airtight plates, of the air storage grooves are fixedly connected with deformation plates. A base is fixedly connected to the interior of the shell, a screw is movably connected to the surface of the base, a supporting frame is fixedly connected to the bottom of the base, a homogenizing groove is formed in the supporting frame and located at the bottom of the oil outlet nozzle, an oil filtering plate is fixedly connected to the bottom of the supporting frame, an elastic plate is fixedly connected to the bottom of the oil filtering plate, and a spring rod is movably connected to the bottom of the elastic plate. When the two screws rotate in a meshed mode with the base bearing, pausing occurs, so that the set thread distance between the two screws is changed, then the connecting positions of the bearings and the screws are lubricated, and the effect of real-time oiling through the working state of the screws is achieved.

Description

technical field [0001] The invention relates to the technical field of airtightness detection of refrigeration compressors, in particular to airtightness detection equipment for twin-screw refrigeration compressors. Background technique [0002] The screw type (ie twin-screw) refrigeration compressor has a pair of rotors with helical teeth that mesh with each other and rotate in opposite directions. Change, periodically change the volume between each pair of tooth slots of the rotor, and then realize the work of suction, compression and exhaust. [0003] The existing screw compressor refrigeration technology is relatively mature. Considering the working characteristics of the screw compressor, the screw rotates continuously, so the lubrication work cannot be ignored. Therefore, the existing technology often adopts regular inspection and adding lubricating oil method, but this method cannot detect the amount of lubricating oil in the screw in real time; in addition, the exis...

Problems solved by technology

[0003] The existing screw compressor refrigeration technology is relatively mature. Considering the working characteristics of the screw compressor, the screw rotates continuously, so the lubrication work cannot be ignored. Therefore, the existing technology often adopts regular inspection and adding lubricating oil method, but this method cannot detect the amount of lubricating oil in the screw in real time; in addition, the existing screw compressor lacks the corresponding air-tightness detection parts, which leads to the reduction of the cooling effect due to poor airtightness. Therefore, a kind of air tightness testing equipment for twin-screw refrigeration compressors came into being
