The harm of cavitation to slurry pumps

We have introduced the harm of cavitation to slurry pumps in previous articles, so why does it cause such serious damage to slurry pumps? This article will take you to understand.
The damage mechanism of cavitation erosion is: first, inward explosion like vacuum erosion damage; second, there is the accelerated impact after the gas-liquid separation of the granular medium in the slurry. Since this type of bubbles are lighter than the slurry, they are easily rotated. The impeller rushes to the inner wall of the sheath and the front and rear guard plates. The joint gap between the guard plate and sheath breaks. The ruptured liquid quickly fills the cavity and then accelerates to hit the wall. This frequent impact will cause fatigue of the slurry pump material. After peeling, the pits after peeling are more likely to retain bubbles and form eddy currents, which will accelerate the wear of the material wall. This type of damage is a comprehensive damage caused by cavitation and high-speed swirling. The flow parts are damaged quickly, and the appearance after damage is like a large honeycomb. It should be noted that gas cavitation and evacuation are two different concepts. Evacuation results in the separation of gas and liquid, while gas cavitation is caused by the dissolution and subsequent rupture of gas and liquid.
