Slurry use of mechanical seals

Slurry use of mechanical seals

1, Before starting slurry pumps , mechanical seals attached to the device to be checked , the cooling and lubrication systems are sound smooth.

2 , The material should be cleaned before starting the pipeline , to prevent rust and impurities into the sealed chamber.

3 , The hand plate moving couplings, check whether the easy axis of rotation , if the plate moving heavy, need to check the relevant mounting dimensions are correct.

4 , Before the normal driving , the need for hydrostatic testing , end-face inspection of mechanical seals , seals and sealing effect of the seal at the cover , if there are questions , one by one checking resolved.

5 , Before starting slurry should remain sealed cavity filled with liquid or seal of the media , if any, should be started individually sealed system ,slurry pump manufacturer the cooling water system shall be put into circulation .

6 , Before normal use , the first operation carried out at atmospheric pressure , temperature rise observed sealing parts is normal , there is no leakage. If minor leaks can run together for some time, so that the end face of a more uniform fit , to gradually reduce the amount of leakage to normal. If running 1-3 hours , reducing leakage still , you need to stop and check .

7 , In normal operation conditions, boost heating can be carried out slowly , respectively , and pay attention to the temperature rise and the end face of the leak , if everything is normal , indicating that you can put into production use.
