Tool for pulling out cylinder sleeve of compressor

Abstract

The invention discloses a tool for pulling out a cylinder sleeve of a compressor. The tool comprises a pull rod, a pressing plate, a stop sleeve, an inner taper sleeve, a taper head, a plurality of first screw rods and a plurality of second screw rods, wherein the first screw rods are in threaded connection with the pressing plate, the second screw rods are in threaded connection with the pressing plate, a through hole is formed in the pressing plate, the pull rod penetrates through the through hole in the pressing plate, a threaded part and a sliding part are successively arranged on the pull rod from left to right, the pull rod and the taper head are connected in a demountable manner, a plurality of grooves are axially formed in the inner taper sleeve, a thrust bearing and a nut sleeve the threaded part of the pull rod, the pull rod penetrates through the stop sleeve, the stop sleeve comprises a baffle and a sleeve, a through hole communicated with the inner hole of the sleeve is formed in the baffle, and the outer diameter of the sleeve is smaller than that of the inner taper sleeve. The tool disclosed by the invention overcomes the difficulties that in the prior art, when the cylinder sleeve is replaced, a cylinder body is difficult to mount and align, the period is long and the processing cost is high.

Description

technical field [0001] The invention relates to the field of removing cylinder liners, in particular to a tool for pulling out a cylinder liner of a compressor. Background technique [0002] Compressor, a driven fluid machine that lifts low-pressure gas into high-pressure gas. It is the heart of the refrigeration system. It inhales low-temperature and low-pressure refrigerant gas from the suction pipe, drives the piston to compress it through the operation of the motor, and discharges high-temperature and high-pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle, thereby realizing Compression→condensation→expansion→evaporation refrigeration cycle. [0003] Generally, compressors are divided into high-pressure compressors, medium-pressure compressors and low-pressure compressors according to the air pressure value provided. Among them, the piston cylinder in the high-pressure compressor adopts a stepped cylinder liner. When the cylinder...
