The leak that appears during installation

If the leakage volume is very small, there is a problem with the static ring sealing ring or the dynamic ring sealing ring. When the amount of leakage is relatively large, it means that there is a problem with the static ring friction. The manual disk car is checked. If there is no obvious change in the leakage, it means that there is a problem with the static ring and the moving ring sealing ring. When there is a problem with the dynamic ring sealing ring, the sealing ring of the static ring will fail.

The leak that occurs during trial operation

After the static test of the centrifugal pump is tested, it will rotate quickly when rotating, and the centrifugal force will be generated, which will leak. The sealing between the shaft and the end cover is basically caused by the damage of the dynamic static ring friction. You can re -disassemble the seal for replacement.

The leak that suddenly appeared during the operation

A large number of leaks suddenly appeared in the work in the work due to changes in work conditions or improper operation. Take time or air erosion can cause pressure for a long time. At this time, the sealed seal will be destroyed. The actual output volume of the centrifugal pump is small, and a large amount of medium will circulate in the pump. At this time, the heat agglomeration will cause the medium to gasification to cause the seal to fail.
