Feedwater pump cavitation concept
When the water pump cavitation occurs due to a large number of bubbles to block the flow channel over-flow caused by the flow down (the smaller the flow path more serious), while changing the flow velocity and direction, reducing the fluid from the impeller blade energy, greatly reduced
Due to a large number of bubbles continue to produce, rupture to bring high-speed impact, the formation of a great pulsating impact, repeated role in the water pump flow channel, the so-called "dripping stone", metal materials often can not withstand such a severe test damage or
When the pump is in the process of cavitation, from the pump inlet (low pressure area) to the outlet (high pressure area), a large number of bubbles will continue to produce, develop, coagulate, rupture caused by repeated high-speed impact and great
