dead head pressure
Thread Content
What does the dead head pressure of a pump mean? Why is it necessary to measure the pump’s dead head pressure during water conveyance?
Dead head pressure should be static head pressure! What do you all think!
Dead head pressure = shut-off pressure. The shut-off pressure of a pump is directly related to the design pressure value for the pipeline.
The translation is: hydrostatic head. Since there is usually a valve at the pump outlet, closing this valve allows one to determine the pump’s maximum head. (Pump characteristic curve)
The ability of a pump to continue running without damage when the discharge is blocked. Recommended only for centrifugal pumps. The term \"dead head pressure\" is, at least in my opinion, not very common. It is generally called the shut-off head, which refers to the head pressure when the outlet valve is closed. The friend upstairs is very professional; kudos to them.
Dead Head means dead zone. It is the ability of the pump to continue operating without being damaged after the pumping function is turned off. It is mostly used in centrifugal pumps. As for the pressure later on, I’m not sure.

This pressure is measured during water transfer operations for the following reasons: to check whether the pump is operating properly and to determine whether it can achieve the required head. It’s just this person’s understanding.
I disagree with what was said on floor 6; it should be the head at zero flow rate on the pump’s performance curve.
I also disagree with the claim about 6L. Translation should be adapted to the actual context, rather than being a rigid literal translation. Among the relevant characteristics of pumps, there is no such thing as them being able to operate without damage after the transfer process has stopped. In fact, if the pump outlet valve is closed, problems will definitely arise after the pump has been running for a long time. Actually, a few people before have already explained it very clearly. Dead head pressure refers to the pressure reached when the pump is operating with the outlet valve closed. In everyday speech, it is commonly referred to as the static head of a pump. I especially admire 5L; they use professional English terms with ease.
