Abstract

A special hydraulic tool for installation and disassembly of a cantilever type impeller mainly comprises an adjusting nut capable of being connected with an impeller center bolt in matching mode, an inner cylinder and an outer cylinder which are mutually matched are sleeved in the adjusting nut, and an oil pressure cavity communicated with an external hydraulic pump is formed between an inner cylinder sleeve and an outer cylinder sleeve. A sleeve capable of abutting against the impeller end wall is connected with the connection center bolt side of the adjusting nut through threads. An inner sealing ring and an outer sealing ring are arranged at the position of the connection gaps at two ends of the inner cylinder sleeve and the outer cylinder sleeve, and a poking rod capable of being matched with an impeller locking nut in matching mode and locking the impeller locking nut is configured on the sleeve. The special hydraulic tool has the advantages of being simple in structure, light in weight, capable of providing large axial force, convenient to install and disassemble and the like.

Description

technical field [0001] The invention relates to a special hydraulic tool for installation and disassembly of a cantilever impeller, especially suitable for the installation and disassembly of the cantilever impeller of nitrogen compressors and air compressors. Background technique [0002] Biaxial and triaxial nitrogen compressors and air compressors usually use cantilever impellers, and the impellers and shafts are connected by bolts, and the torque is transmitted through end pins or triangular shafts. The central bolt of the impeller needs to ensure a relatively large axial tension to realize the tight fit of the mating surfaces of the impeller and the shaft. Due to the special structure of biaxial and triaxial nitrogen compressors and air compressors, the tooling that needs to be designed has the characteristics of providing large axial tension, simple structure, light weight, and convenient installation and disassembly. The existing tooling cannot Meet the above req...
