time:2012-03-15  |  visits:2408  |  tags:Centrifugal pump manufacturers,,,
Detail:

  Centrifugal pump stop is mainly composed of mechanical seal failure causes. The performance of the failure is mostly leak, leakage reasons have the following kinds:
  (1) the leak sealing ring movement, the main reason is: surface flatness, roughness not meet the requirements, or surface is slashed; End have between particulate matter, causing two end can't also run; Installation does not reach the designated position, way is not correct.
  (2) compensation ring seal leakage, reasons: gland deformation, preloaded force not uniform; Not installed correctly; Sealing ring quality does not accord with standard; Sealing ring type selection is wrong.
