In an oilfield water injection system, at the same water injection station, can centrifugal pumps and piston pumps operate in parallel?
Thread Content
Expert consultation: In an oil field high-pressure water injection system, with the same water injection station and the same pipeline network, if a high-pressure centrifugal pump and a high-pressure plunger pump are used simultaneously, can these two pumps operate in parallel? Are there any things to keep in mind?
As long as the pump outlet and pressure are the same, that’s fine. It is just that the flow rates of these two types of pumps need to be taken into consideration during operation, especially for centrifugal pumps. The pump body will heat up without flow.,,,, For reference.
Yes, but the parameters need to match. Positive displacement pumps are rigid, while centrifugal pumps are flexible and can automatically adjust their operating parameters according to the conditions of the system
Thank you. That makes sense. I have to give it a try.
Thank you, I think there shouldn’t be any problems either.
With the same outlet pressure and the same operating conditions, there is no problem. Note that check valves should be installed at the pump outlet pipelines to prevent backflow of the medium caused by pressure differences in abnormal situations.
I am very grateful. Happy New Year.
