Regarding the rinse water pressure setting
Thread Content
What is the typical pressure in the seal chamber of a mechanical pump? How to tell? Is it the same pressure as at the pump outlet? 32 What is the typical pressure setting for the rinse water? Please give me your guidance, dear shrimp. . . . . .
Look at the method used by the impeller to balance axial forces
It’s a good time to learn* it. Previously, the pump at the facility had a head of 50 meters; specifically, 6 barg of nitrogen was used to reduce the pressure to 5.5 barg, which was then supplied to the seal cooling fluid tank to prevent the material pumped from leaking into the cooling fluid. It was said later that low pressure would be sufficient; I don’t remember exactly how low. The coolant should be one that does not affect the pumped material and is chemically compatible.
The most accurate value is a pressure 1–2 bar higher than that in the sealed chamber; this depends on your inlet pressure, head, and whether there is a secondary impeller or not. If accurate measurement is desired, add a tee to the flushing port with a pressure gauge connection; this is the most straightforward approach: P
