Description

A special disassembly tool for mechanical seal

technical field

The utility model relates to a special assembly and disassembly tool for mechanical seals.

Background technique

The mechanical water seal of the water pump on the boiler is at the connection part between the pump body and the motor of the water supply pump, and is connected with the thread of the original body, and the disassembly part is the outer hexagon. Due to the small space in the installation location, all kinds of wrenches cannot be used every time it is disassembled during the maintenance process. Hand hammers and screwdrivers must be used to remove looseness, which can easily cause damage to the mechanical water seal. This can easily cause damage to components and waste maintenance time. the

Utility model content

In order to solve the deficiencies in the prior art, the utility model provides a special disassembly and assembly tool for mechanical seals.

In order to solve the above technical problems, the utility model adopts the following technical scheme: a special disassembly tool for mechanical seals, including a snap ring with a regular hexagonal hole, a connecting rod located on the same plane as the snap ring is provided on the outside of the snap ring, and the connecting rod There is a handle bar at the end.

The thickness of the snap ring is 8mm.

The included angle between the handle rod and the connecting rod is 120°.

Using the above technical scheme, using the principle of leverage, the regular hexagonal hole of the snap ring is placed on the outer hexagonal part of the mechanical seal loosening ring shaft sleeve, and the fixing bolt can be easily loosened by turning the handle bar, and the mechanical seal can be disassembled. The utility model is easy to manufacture and low in cost. It is convenient and quick to use, reduces labor intensity, and improves the disassembly speed of the mechanical seal. 2-3 wrenches of different sizes can be made according to the mechanical seal to avoid damage caused during the disassembly of the mechanical seal and reduce maintenance costs. The utility model is suitable for the disassembly and installation of all Grundfos HQQE series mechanical seals, and can be widely used inside and outside all water pump maintenance industries.
