Description

Technical Field

[0001] The utility model relates to the technical field of pump cover assembly, in particular to an assembly tool for a pump cover and a pump shaft. Background Art

[0002] The pump cover is a part that separates the rotating part and the stationary part of the pump. It not only protects the internal components of the pump from damage, but also acts as a seal when the pump is working to ensure the normal operation of the pump. A pump shaft will be equipped on the outside of the pump cover to facilitate the use of the pump cover.

[0003] The existing pump cover and pump shaft equipment usually places the pump cover on a table and then assembles the pump shaft to the inner side of the pump cover. However, since the position of the pump cover is not restricted, the pump cover is easily offset during the assembly process, which makes the installation of the pump cover and the pump shaft more difficult. Therefore, an assembly tool for the pump cover and the pump shaft is proposed to solve the above problem. Utility Model Content
