Cavitation in liquefied gas pumps
Thread Content
Judging from the morphology in the figure below, is it caused by cavitation?
I’m basically an amateur in this area; facing such a serious situation, I’ve really learned something!
It mainly depends on the medium you are using; sometimes it’s corrosion of the medium. If there is no corrosion, then it’s basically caused by cavitation
Medium: Liquefied gas after reformation desulfurization
Is the pump operating in reverse flow or in suction mode? What is the inlet pressure, and what is the temperature of the medium? Please provide some details
The pump is experiencing backflow; inlet pressure is 0.95 MPa and the temperature is 40°C℃
I’ve encountered a similar situation; it was liquefied gas containing sulfur, which caused corrosion and penetration of the stainless steel impeller. Of course, the possibility of cavitation cannot be ruled out either; a specific analysis is needed based on the pump’s operating conditions
