Why does cavitation occur? What are the causes of cavitation?

From the very beginning of our article, we have been expressing the relationship between pressure and cavitation. The problem in atmospheric pressure also causes cavitation. Cavitation damages may be caused by the following reasons.
• Atmospheric pressure at the points where the pump and turbine operate may be low, so cavitation may have occurred.
• There may be a possibility of air or some gases dissolved in the liquid.
• The suction line may be long or the suction valve may be closed.
• Flow may be above normal standards.
• If the resistance of the suction line is high, this may cause cavitation.
What are the problems caused by cavitation?
Cavitation formation not only shortens the life of the pump or causes it to run noisy, but also causes some other problems. Loss of performance in the system is one of the most serious problems. As a result of cavitation, noise occurs and noise reduces the operating efficiency of the pump. Besides the noise, the vibration problem can also be seen. A wear problem may occur over time and the fluid in the system may lose its properties after a while.

How to understand that there is cavitation in the pump?

One of the ways to find out if there is a cavitation problem in the pump is to make a pressure comparison. The pressure of any point in the fluid is measured. If the value of the fluid is equal to or lower than the evaporation pressure, then cavitation damage is likely. Regular pressure tests give an effective result to prevent cavitation in the pump. Analyzing the system and working conditions and taking the necessary precautions will reduce the risk of cavitation and provide a healthy working environment.
