Causes of water hammer in the pump outlet pipeline
Thread Content
The outlet pipeline of a centrifugal pump has a diameter of DN200. When the flow rate is increased via a valve on this outlet pipeline, water hammer noise occurs; however, the water hammer disappears when the flow rate is reduced. What is the cause of this, and how can this problem be resolved?
How can there be water hammer? Please specify the medium temperature
There are two scenarios: 1. The pump’s head is insufficient； 2. The terminal pressure of the outlet pipe increases too much ； By increasing the pump’s outlet flow rate, you reduce the outlet pressure, which is not sufficient to force the fluid into the connected equipment! ! ! Of course, it might also be related to whether the diameter of the pump’s outlet pipe is too large! ! !
