Description

Technical Field

[0001] The utility model relates to the technical field of compressor installation, in particular to an assembly tool for a rotor seat and yin-yang rotors of a screw compressor. Background Art

[0002] A compressor is a driven fluid machine that lifts low-pressure gas to high-pressure gas. It is the heart of the refrigeration system. Compressors are divided into piston compressors, screw compressors, centrifugal compressors, linear compressors, etc. Screw compressors are generally composed of a housing, an electric motor, a female rotor, a male rotor, a control device, and a cooling system. The female rotor and the male rotor rotate to compress the air. At present, the female rotor and the male rotor are generally installed manually. The compressor rotor seat housing is placed on the ground, and then the female rotor and the male rotor are pressed in from the top. In this way, the compressor rotor seat housing is easy to move, and the clearance between the female rotor and the male rotor after installation cannot be guaranteed, which will affect the function of the compressor.

[0005] Preferably, the mounting holes are provided in a plurality of groups and are spaced apart along the vertical direction of the rotor seat fixing plate.

[0006] In summary, the technical effects and advantages of the utility model are:

[0007] In the utility model, a mounting frame is provided to facilitate stable placement, so that the rotor seat is installed off the ground, and the rotor seat is installed on a rotor seat fixing plate, which can prevent the rotor seat from shifting during the installation process. A hydraulic rod is used to push the female rotor and the male rotor into the interior of the rotor seat respectively, so that the gap between the female rotor and the male rotor can be guaranteed, thereby ensuring the working effect of the compressor.
