Mechanical Seal Installation And Shutdown

1. Keep the sealed cavity filled with liquid before starting. When transporting solidified media, steam is used to heat the sealed cavity to melt the media. The car must be cranked before starting to prevent the soft ring from breaking due to sudden start.

2. For mechanical seals that use the external oil sealing system of the pump, the oil sealing system should be activated first. The oil sealing system is finally stopped after stopping.

3. After the hot oil pump is stopped, the cooling water in the oil seal cavity and the end face seal should not be stopped immediately. The cooling water should be stopped when the oil temperature at the end face seal drops below 80 degrees to avoid damage to the sealing parts.
