I would like to ask about the impact of impeller scaling on the performance of pump machinery! !
Thread Content
As shown in the figure, what effects will a uniform layer of scale forming inside the impeller have? Currently, the operating condition of this pump is characterized by increased noise from the pump; there are also sounds associated with pumping vacuum or cavitation. Is this caused by scaling, and what is the principle behind it? Thank you all! ! ! !
For pumps with a low specific speed, the effect of a low net positive suction head is significant; otherwise, the effect is minimal
It’s recommended to clean off the scale first, run it to see how it performs, and then discuss further :)

After shedding, a depression forms inside it, causing turbulence in the fluid, and things become complicated from there on, with many unexpected situations arising; P
It affects dynamic balance; once scaling occurs, the dynamic balance is compromised, vibration of the water pump increases, and the lifespan of the bearings and seals is significantly reduced
