The net positive suction head of a pump refers to the minimum pressure difference that must be maintained to prevent cavitation from occurring in the pump. When the pressure of the liquid inside the pump drops below its vapor pressure, bubbles form, which can affect the proper operation of the pump and even damage it. Therefore, understanding and controlling the net positive suction head is very important for the stable operation of pumps. .
The problem of pump cavitation is something that cannot be overlooked in design and selection
