Question regarding the outlet pressure of the liquid oxygen pump
Thread Content
We plan to introduce liquid loading, which will also be used for back-filling liquid oxygen; a centrifugal pump is chosen for this purpose. I’m not sure whether 0.8 MPa at the pump outlet is an appropriate value The main cooling height is around 13 meters. Besides the pressure drop, what other factors affect the cryogenic liquid pump? What do all the seniors use? I would appreciate some advice: lol
For normal oxygen filling pumps, 8 bar is sufficient~~ Also consider the flow rate, which is generally around 20 cubic meters per hour~~ As for backflow of liquid oxygen, it depends on the highest point of your piping; if it’s 13 meters, an 8-kilogram pump will provide enough head pressure~~
