How to eliminate the water hammer effect
Thread Content
Our equipment is electrolytic equipment that uses cooling water for temperature control; the inlet water temperature is around 30 degrees. However, the cooling process is controlled by solenoid valves, and when cooling is not in effect, the water in the cooling pipes heats up and turns into steam. Currently, there is often noise at the points where the cooling water from each piece of equipment connects to the main cooling water pipeline. After checking, I found that it’s due to the water hammer effect. How can this problem be resolved?
This issue occurs because, when heating takes place, the steam pressure inside the cooling water pipes exceeds the inlet water pressure. Installing a vent valve at a higher point in the cooling water system can prevent this problem! But it will affect the material of the cooling water pipes; with sudden changes in temperature, the pipes are prone to problems.....

An automatic exhaust valve can be used, or an electromagnetic valve can be added as well – the valve opens to allow air to reach atmospheric pressure when cooling is not taking place, and it closes when water is added. But could this accelerate corrosion?
The opening speed of the solenoid valve doesn’t need to be too fast! There’s also a water hammer eliminator! !
