Description

Technical Field

[0001] The utility model relates to the technical field of disassembly tools, in particular to a tool for removing a cylinder seal. Background Art

[0002] The oil cylinder includes a cylinder shell and a piston rod. In order to prevent problems such as internal leakage of hydraulic oil, a seal is usually provided in the gap between the cylinder shell and the piston rod. The seal is mainly made of rubber and synthetic resin. The main requirements for the seal are good sealing effect, good pressure retention effect in a static state, strong pressure bearing capacity during movement, anti-extrusion, low friction coefficient, and long service life. During the use of the oil cylinder, the seal is often damaged. Once the seal is damaged, if it is not replaced in time, the oil cylinder will not operate normally.
