Produce the phenomenon of cavitation criteria
　　
Cavitation bubbles begin to appear at the blade inlet edge (nascent cavitation, NPSH) until the defined maximum bubble length (eg bubble length 5mm) is reached. In bubble observation experiments, the pressure at the inlet was gradually reduced until the first visible cavitation bubble appeared.
　　
· Cavitation of the pump may be caused by cavitation head lift (ΔH), reaching the defined maximum descent value △ H = 0.03H or in some high-speed operation of the screw pump often appear △ H = O.OOH (refers to the production of cavitation The initial stage of head descent). The corresponding NPSH value with NPSH. And NPSH. To represent.
　　
• Cavitation of the pump may decrease in efficiency (Δη) due to cavitation, reaching the defined maximum descent value (eg Δη = 0.03η).
　　
Pump cavitation may be due to cavitation head (â–³ H) decreased, leading to head failure (drop).
　　
Cavitation of the pump Material corrosion of the volute pump, which may be caused by cavitation, reaches the maximum defined for a fixed period of time.
　　
Pump cavitation may increase the noise level caused by cavitation, reaching the maximum noise level defined.
Cavitation refers to the phenomenon of the formation of a hollow product such as a vapor bubble in a liquid water stream and a sudden rupture. For centrifugal pump cavitation in the emergence of scale and impact of cavitation have different standards , gas and steam cavitation and cavitation is different.
