Abstract

The invention provides a tool for installing and removing screw compressor nuts. The tool comprises a bottom plate, a first bolt, a second bolt, a sleeve and a hydraulic wrench, wherein a first screw hole and a second screw hole are formed in the bottom plate; the first bolt penetrates through the first screw hole to be connected with the compressor shell; the second bolt penetrates through the second screw hole to be fixedly connected with a driven screw of the compressor; a tooth dike matched with a tooth groove in the outer part of the compressor nut is arranged on the inner wall at one end of the sleeve; a first through hole matched with the hydraulic wrench is formed in the other end of the sleeve; a second through hole allowing the sleeve to penetrate through is formed in the bottom plate. The tool provided by the invention can remove and install nuts of the screw compressor, thereby being time-saving and labor-saving.

Description

technical field [0001] The invention relates to a tool for disassembling nuts of screw compressors. Background technique [0002] A screw compressor is a volumetric gas compression machine whose working volume makes a rotary motion. It is divided into a single-screw compressor and a twin-screw compressor. The twin-screw compressor is a more advanced compression machinery. The twin-screw compressor includes a driving screw and a driven screw that mesh with each other. The driving screw drives the driven screw to rotate to compress and discharge the oil. The driving screw and the driven screw are arranged in the shell, which is a rotary body structure, its end is open, and the end is sealed by the end cover. The end cover and the end of the shell are connected by bolts and locked by nuts. The torque of the screw lock nut is 7000LBF.FT, and manual disassembly and assembly of the lock nut is time-consuming and laborious. Contents of the invention [0003] Based on the above...
