Pumpe kavitation
WebCavitation most frequently appears when centrifugal pumps are used – these pumps rely on altering pressure inside the unit to generate a vacuum, pushing the liquid into the unit rather than pulling it in. Cavitation can occur in submersible pumps as well, but it is less common.; Cavitation can have a significant detrimental effect on pump performance … How to Recognize Pump Cavitation. Cavitation sounds like marbles or gravel circulating through the pump, pipes, or hoses. The effects of prolonged cavitation are visible on the pump impeller and other components. Typical indications of cavitation: Noise; Vibration; Seal/bearing failure; Impeller erosion; Higher than usual power consumption

WebJun 15, 2024 · Pump cavitation is one of the most potentially troublesome issues that can occur in the various fluid handling systems used by the food and beverage industry. It is triggered by a pressure drop in the liquid moving through the eye of the impellor in a centrifugal pump, causing bubbles to form. WebApr 11, 2024 · What Is Pump Cavitation. Tuesday, April 11, 2024. Cavitation occurs when the liquid in a pump turns to a vapor at low pressure. There are 2 kinds of cavitation – suction and discharge. Suction cavitation occurs when there is not enough flow to the pump resulting in bubbles (cavities) at the eye of the impeller.
WebPump cavitation in an impeller is the result of a drop in the pressure of a moving liquid through the impeller’s eye. This reduced pressure causes bubbles to form, as the pressure of the liquid continues to fluctuate and drop, the bubbles collapse. Implosions of these vapor pockets can be so rapid that a rumbling or cracking noise is produced ...
