Liquefied hydrocarbon pump
Thread Content
The suction pipeline for the liquefied hydrocarbon pump is approximately 200 meters long, with a flow rate of 30 cubic meters； The head is set at 60 meters ； Not including elbow valves ； How should the net positive suction head be selected for a pump like this? How to avoid cavitation.
The pump body has a cooling system, so it should work fine when activated; generally, liquid hydrocarbon pumps come equipped with two cooling systems.
200 meters of intake pipeline? If it’s a centrifugal pump, there are serious doubts about whether it will be able to draw fluid up
Reply to 1# Jiang Zhiqing: Choose pumps with a low NPSHr, such as vertical tube bag pumps and centrifugal pumps equipped with an impeller.
I think more detailed information still needs to be provided. Because calculating NPSH requires not only the pipe diameter and length, etc., but also the height, the pressure in the suction tank—if any—and the vaporization pressure, among other things
