Degree of frosting on the sealing discharge coiling tube of the liquid oxygen pump
Thread Content
What should be the degree of frosting on the winding tube for the exhaust of the liquid oxygen pump seal mixture?
One-third of the French Low Temperature Stars will do; where do you use those?
We are CRYOSTAR
For the low-temperature star Cryostar, frost formation during normal operation can reach about half.
We can’t dismiss the experience-based approach outright either~~ Hehe~~
Few places have saturated humidity on sunny days; therefore, general experience dictates one-third frost~~
Give floor 4 a thumbs up. When I was first working with air separation, the experienced workers told me that one-third frost formation is sufficient, as long as there is a slight airflow felt when touching it. What I do now is: at point A, a pressure difference is maintained to ensure that liquid does not leak into the motor, with a value of 20 to 30 kPa; at point B, a pressure difference is maintained to prevent sealing gas from entering the pump, with a value of 1 to 2 kPa. At the same time, ensure that the flow rate of the sealing gas is within the specified range.
Thank you. I know about the control range, but the manual doesn’t specify the degree of frosting on the mixture exhaust coil
I don’t know if the manufacturer has such a requirement
