What do you mean by surging and choking in pumps and how to control it

Question

Accepted Answer

Surging and choking are phenomena that occur in pumps. Surging is the unstable flow condition where the flow rate fluctuates, while choking is the condition where the flow is restricted.

Surging occurs when the flow rate through the pump exceeds the pump's capacity, causing the flow to become unstable.
Choking happens when the flow rate is restricted due to a blockage or narrowing in the pump or piping system.
Surging can be controlled by adjusting the pump speed or using surge control devices like surge tanks or bypass lines.
Choking can be prevented by ensuring the pump and piping system are properly sized and maintained, and by using filters or screens to prevent blockages.
Examples of surging include cavitation in centrifugal pumps or pulsation in reciprocating pumps.
Examples of choking include a clogged filter or a valve that is partially closed.
