Pump cavitation on the pump what harm?

Pump coal mine is equivalent to the coal mine "heart", the performance of the pump performance directly affects the safety of coal mines, disturbing the normal operation of the pump is a big problem of damage to the pump impeller blades, resulting in such damage The main reason is often the phenomenon of cavitation occurred impeller. Today, the pump cavitation phenomenon on the hazards of the pump what. Pump cavitation on the pump what harm? Severe effects on pump after cavitation Phenomenon When cavitation develops to a certain extent, it will affect the performance of the pump and prevent its normal operation. Mainly in the following areas: (1) the pump performance changes Cavitation at birth, the pump outside the characteristics of no significant effect. Cavitation development to a certain extent, the pump power, efficiency, flow and head and other parameters will suddenly decline. When cavitation is fully developed, the effective flow area of ​​the flow will be reduced a lot, resulting in interruption of flow, can not work. (2) Caused by vibration and noise Bubble burst, the liquid particles impact each other, resulting in noise and vibration of the unit, both excited each other so that the pump produces a strong vibration, known as cavitation resonance phenomenon. (3) The destruction of the surface of the overcurrent component Cavitation damage will greatly shorten the life of the pump, erosion and corrosion serious, it will produce leaf rupture or perforation and other major accidents.
