1. Preparations and precautions before starting

a. Comprehensively check the mechanical seal, whether the attachments and pipeline installation are complete, and whether they meet the technical requirements.

b. Before starting the mechanical seal, perform a static pressure test to check whether the mechanical seal is leaking. If there are too many leaks, the cause should be found out and eliminated. If it is still invalid, it should be disassembled, inspected and reinstalled. Generally, the static pressure test pressure is 2~3 kg/cm².

c. Rotate the pump to the crank to check whether it is brisk and even. If the crank is difficult or does not move, check whether the assembly size is wrong and whether the installation is reasonable.

2. Installation and shutdown

a. 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.

b. 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.

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