1, vibration and noise. Bubble collapse, the liquid point of mass impact on each other, but also impact on the metal surface, resulting in a variety of frequency noise, serious cases can be heard in the pump "splat" of the explosion, while causing vibration of the unit.
2, reduce pump performance. Cavitation produces a large number of bubbles, blocking the flow path, destroying the continuous flow of liquid in the pump, so that the pump flow, head and efficiency decreased significantly.
3, the destruction of overflow components. Due to mechanical stripping and electrochemical corrosion, so that the destruction of metal materials, usually by the parts of the destruction of the vapour corrosion in the impeller outlet near the impeller and discharge chamber near the inlet. Vapour corrosion in the early stage, the performance of the metal surface pitting, and then the surface showing spongy, groove, honeycomb, fish scale and other traces; serious cases can cause perforation of the blade or the front and rear cover plate, and even the impeller rupture, resulting in serious accidents.
