What causes the cavitation of slurry pump?

The cavitation performance of Slurry Pump can meet the requirements when the pump works in the reverse state. So what causes the cavitation. Cavitation is the process by which a flowing liquid creates a bubble and breaks. In addition to mechanical force, cavitation failure is also accompanied by electrolytic, chemical corrosion and other effects, resulting in the early failure of the flow parts. There are many reasons for cavitation, such as suction pressure, the density of the conveying medium, gravity acceleration, suction height, suction tube resistance coefficient, suction tube length, suction tube diameter, fluid flow rate in the tube, vaporization pressure, etc. The most important factors are suction height, fluid velocity in the tube, density of the medium, and suction tube length.
