The outlet valve of the water pump vibrates severely
Thread Content
The valve head (valve stem and electric actuator) of the DN500 electric outlet valve for one of the water pumps in our factory experiences significant vibration during pump operation (the vibration level is over 120 as measured by a seismograph); we’re not sure what the cause is. The vibration in the outlet pipe, on the other hand, is not severe (around 14).
If it is a gate valve, it may be caused by vibration of the gate valve disc.
Perhaps it is due to different valve openings; under specific conditions such as pressure, flow rate, and the size and shape of the chamber, greater turbulence is generated within the valve chamber, which causes this issue
A too large outlet diameter, too small outlet opening, or a large pressure difference before and after the valve can also cause loud noises
The water pressure is high and the valve opening is too small
The large diameter results in high flow rates and fast flow speeds, as well as significant impact forces. Severe throttling occurs at the gate, creating a large pressure difference before and behind the gate, which leads to intense turbulence. This causes severe vibration of the gate; in severe cases, the valve gate may collide with other components, the valve stem may deform, and sealing issues may occur, leading to easy damage to the valve
