A: correctly determine the water pump suction height, to ensure that the impeller inlet pressure is not lower than the vaporization pressure.

Two: try to reduce the loss of water suction pipe head. The greater the loss, the lower the pressure at the pump inlet, the easier the water will vaporize. Because this wants to shorten the length of bibulous conduit as far as possible, reduce the accessory on conduit road, conduit inner wall wants smooth and increase bibulous conduit diameter appropriately.

Three: the pump fall well installation. If due to excessive water absorption caused by cavitation, the pump can be installed in the hole or below the surface, near the water suction.

Four: the use of jet to improve the inlet pressure.

Five: try to make the pump in the rated conditions of operation. If the pump in the rated head or more than the rated speed of operation, the flow of the pump is bound to be greater than the rated flow rate, impeller inlet flow speed is bound to increase, the pressure will be further reduced, therefore, can not arbitrarily reduce the pump head and improve the speed of the pump.

Six: set the induction wheel at the inlet of the water pump, or use anti-cavitation pump parts.
