Description

Technical Field

[0001] The present application relates to the technical field of mechanical seal disassembly, and in particular to a mechanical seal disassembly tool. Background Art

[0002] The mechanical seal is the axial end face seal of the sand pump. It has a high surface finish and is coated with mechanical oil. It is strictly forbidden to hit or knock during the installation and disassembly process to prevent the seal from failing due to friction damage. Since the sand pump operates continuously underwater for a long time, it needs regular maintenance. Among them, the removal of the mechanical seal is a key step and also a difficult step to operate. The original method of disassembling the mechanical seal is for two staff members to cooperate and use a crowbar to pry it out with force. The action frequency must be consistent and the force must be uniform. Not only is the disassembly difficult, time-consuming and labor-intensive, but it is also very easy to damage the shaft and the sealing shell. Due to improper disassembly, the number of scrapped mechanical seals accounts for a large proportion of the number of repairs.

[0003] Therefore, how to avoid the problem of mechanical seal failure caused by improper disassembly is a technical problem that technical personnel in this field currently need to solve. Utility Model Content
