Mechanical seal issues

Could it be a problem with the pumping ring?

Check if the temperature is normal! Too high a temperature can easily cause fluctuations in the pressure of the sealing water.

Could it be due to fluctuations in the pressure of the balance tube, internal leakage, or the fact that the medium is prone to vaporization?

Observe whether the level of the isolation fluid drops quickly If so, it should be the first seal on the double-end face that has failed

Is there a discharge valve at the bottom of the energy storage tank (sealant tank)? Release some liquid from it and check its color and odor to determine whether it contains any hazardous substances. Since two sets of mechanical seals are used, the substance in question is likely toxic and harmful; it must not leak into the air. Such substances usually have an odor, allowing for identification by scent. Even if they are colorless and odorless, odors are often added intentionally, such as in the case of liquefied gas； Additionally, a pressure gauge is usually installed on the accumulator (isolation tank). If the pressure exceeds that of the mechanical seal cooling fluid (isolation fluid) itself, it means that there is leakage from the medium side; the mechanical seal inside has broken or the O-rings have corroded. If the pressure does not increase but only fluctuates, then the leakage amount is not significant; it can be used as a backup pump, and it can be repaired once the conditions are right

Stop the pump, shut off the cooling medium, and check whether there is an internal leak of the transport medium
