Issues regarding the flushing of the mechanical seal face in hot oil pumps
Thread Content
The inlet temperature of the hot oil pump at the bottom of the tower where I am working is around 230 degrees Celsius. The mechanical seals, both those at the connected ends and those at the unconnected ends of the pump, are flushed with deionized water. I would like to know exactly which part of the mechanical seals is flushed with deionized water What role does it play? Please ask an expert for help! Thank you!

The corresponding flushing scheme is PLAN62; it connects to the Quench port (Q) on the sealed end cover and discharges through the Drain port (D) at the bottom. It helps to reduce temperature and prevent coking
Flush the static ring seat on the side of the mechanical seal that is exposed to the atmosphere, with fluid entering from above and exiting from below; in other words, fluid enters rapidly for rapid cooling, while the liquid is discharged from the outlet. This helps to reduce heat generated in the friction pair, prevents coking, and extends the service life of the mechanical seal!
