WitrynaImpeller definition, a person or thing that impels. See more. WitrynaAxial-flow pumps, in addition to providing high anti-cavitation properties, must have high anti-erosion properties to ensure the required lifetime of the pump. Erosion damage of surfaces occurs when the net positive suction head (NPSH) significantly exceeds its critical value. The object of the study in this article is the axial-flow pump with a …

Axial-Flow Pump with Enhanced Cavitation Erosion Resistance

Impellers in agitated tanks are used to mix fluids or slurry in the tank. This can be used to combine materials in the form of solids, liquids and gas. Mixing the fluids in a tank is very important if there are gradients in conditions such as temperature or concentration. There are two types of impellers, depending on the flow regime created (see fi… WitrynaIn all such known impellers, the tip portions of the blades (i.e. the portions close to the periphery of the impeller) are either (1) straight and truly radial, (2) straight and backswept relative to the radial direction, (3) backswept and curved relative to the radial direction, the curvature of said tip portions being constant along their length. east flat rock nc things to do
