GZYB residue pump different leakage analysis of the situation When there are problems with the oil pump, then those conditions will cause leakage of the GZYB residue pump, if there is leakage of the GZYB residue pump, what should we do?
1. Leakage during static test installation If the leakage is small, it is mostly a problem with the moving ring or the static ring seal ring. When the leakage amount is large, it indicates that there is a problem between the dynamic and static ring friction pairs. GZYB residue pump on the basis of preliminary observation of leakage, determine the location of the leak, and then hand-wheel observation, if there is no significant change in the amount of leakage, static and dynamic ring seal ring problems: dynamic and static ring friction pair problems; dynamic ring seal Circle problem, static ring seal failure and other issues. In addition, leaky channels can also exist at the same time.
2. Leakage occurred during test run After GZYB mechanical seal with residue pump is tested after static test, the GZYB residual oil pump will suppress the leakage of the medium due to the centrifugal force generated by high-speed rotation during operation. Therefore, the elimination of sealing failures between shafts and end caps is basically due to the destruction of the friction pair of the dynamic and static rings. Most need to re-install, replace the seal.
3. Sudden leakage during normal operation The sudden leakage of the GZYB residue pump during operation is mostly caused by large changes in operating conditions or improper operation and maintenance. Evacuate, cavitation, or pressure for a long time, resulting in seal damage; the actual pump output is small, a large number of medium pump circulation, heat accumulation. Gasification caused by the medium, leading to seal failure; for a longer period of shutdown, there is no manual disc brake when re-starting, the friction side of the friction surface due to adhesion and tear off the sealing surface; corrosive, polymeric, gelling substances in the medium increase; ambient temperature Rapid changes.

The above kinds of leakage conditions should be based on the problem to choose the appropriate solution, can change, can repair repair. Can not just minor repairs, reluctantly let GZYB residue pump more use for some time, and other major problems before major repairs.
