Control and adjust the installation height of the pump so that the installation height between the suction port of the pump and the liquid surface does not exceed the maximum allowable installation height, especially for mobile fire pumps, if they cannot absorb and discharge liquid normally, the installation height may be inappropriate. It can be solved by reducing the installation height or reverse installation;
Or add a small-capacity storage tank in front of the pump to increase the height of the liquid level and increase the static pressure, thereby shortening the distance between the liquid level of the suction storage tank and the suction port of the pump to prevent cavitation;
It can also prevent cavitation by reducing the flow resistance loss on the pump suction line. Shorten the length of the suction pipeline as far as possible within the allowable range, reduce the number of pipe fittings such as elbows and valves, and appropriately increase the diameter of the suction pipeline;
By improving the strength and abrasion resistance of the pump material, it can also effectively reduce the erosion of the pump caused by cavitation, so as to reduce the damage caused by cavitation to the pump and prolong its service life. In the selection of the impeller, it is possible to choose high hardness and high elasticity materials with strong cavitation resistance.
