Liquid oxygen pump return valve
Thread Content
Do any of you have good methods using liquid oxygen pump return valves to prevent cavitation wear?
This generally won’t experience cavitation, right? If cavitation does occur, there’s a problem with your oxygen pump. 1. It would be fine to set shorter timing for the sequential drainage of air from the pump body and its outlet, so that no gas accumulates. 2. Ensure that your vent valves are functioning properly to prevent pressure buildup later on
Regarding the flashing and cavitation that occur behind the time-regulating valve~~
Oh, I don’t think the impact is that great. Waiting for experts to answer: lol
Did cavitation really occur? ~~Common methods to address cavitation and flashing in control valves include: 1. Increasing the length of the pipes at the valve’s inlet and outlet; 2. Implementing multi-stage pressure reduction, by installing a shut-off valve or throttle orifice upstream or downstream of the control valve; 3. Using cavitation-resistant sleeve control valves or labyrinth-type control valves; 4. Choosing control valves made of materials with greater hardness, as these have a certain resistance to cavitation
It depends on the status of the valve’s inlet and outlet~~ Also, valve selection and pipeline design are important factors~~
If this isn’t resolved properly, could there be a risk of an explosion?
Detonation can occur in the entire oxygen pump system, as long as the three elements of combustion are present~~
Many manufacturers now offer upgraded valve core assemblies that can withstand high levels of cavitation
Why not turn off the reflux valve? We just turned it off.
