Mechanical seal form KCB gear pump maintenance

First, the leakage of the sealing surface of the dynamic and static ring, the main reasons are: the flatness of the end face, the roughness does not meet the requirements, or the surface is scratched;

There are particles between the end faces, resulting in the two end faces can not operate in the same way;

Installation is not in place, the way is not correct.

 

The second compensation ring seal leakage, the main reasons are: gear oil pump gland deformation, preload is not uniform;

Incorrect installation;

Sealing ring quality does not meet the standard;

Incorrect selection of sealing ring.

 

The shutdown is mainly caused by the failure of the mechanical seal.

The performance of failure is mostly leakage, there are many reasons for leakage, which can be divided into static and static ring sealing leakage and compensation ring sealing leakage.
