Mechanical seal oil exhaust issue of PL53A
Thread Content
After replacing the seal on a methanol pump (with modular seals connected in series), the static ring broke down shortly after the pump started operating. It is suspected that the sealing oil did not reach the seal chamber, as there was gas present in the sealing oil. Does anyone know how to remove the gas from the seal chamber?
There is usually a standard exhaust process, right?
When filling the seal fluid tank, do not connect the return oil pipeline to seal 53A (the section where the return oil pipeline is connected to the seal gland); connect it after the seal oil starts to flow out, which helps to remove the air inside.
For mechanical seals using a 52/53 flushing scheme, in the BI/BO design one port is always located at the top, which allows air to be discharged into the tank. If this cannot be confirmed, an interface can be opened on the flushing pipe to check whether seal fluid is coming out
