How to understand the reason for pump cavitation?
Thread Content
If the medium being pumped changes, it may cause the pump to experience vacuum conditions during operation. For example, when an oil pump transports oil that contains water, this can lead to vacuum in the pump. The mechanism behind this is not entirely clear; if the oil contains water, does vaporization occur within the oil inside the pump, or within the water? Could someone explain it to us? Thank you
Pumps must be used in strict accordance with the operating conditions specified for them. Your question is whether the density of the medium is suitable for the pump’s operating conditions; there are many types of oils, each with different physical and chemical properties. In conditions of higher and lower than water density, the pump may experience an increase or decrease in outlet pressure. Pumps can experience phenomena such as cavitation and air locking, which will cause them to fail to operate properly. It is best to understand this by analyzing the physical and chemical properties of the working medium, for reference.
