Why can't the centrifugal pump pump the vacuum?
Characteristic equation of centrifugal pumpStudy the effect of fluid on centrifugal pump to obtain energy.The experimental condition of u is that the ideal fluid of unit weight bends the flow between blades at infinity.U investigated the mechanical energy balance of the fluid between the adjacent two inlet and outlet sections, that is, the relationship between theoretical pressure head and theoretical flow.
Running process: depending on the centrifugal pressure of the liquid in the impeller, the liquid is sucked into the liquid, and the liquid in the pump shell has the conversion of the energy form, so that the fluid can obtain the mechanical energy mainly with the static pressure.The characteristics of the system: the suction diameter than out of large diameter, the general valve installed.
Condition:The pump shell must be filled with liquid under certain installation height and running without leakage.What is the phenomenon of centrifugal pump? What harm does it have? How to eliminate?)
Working principle (taking centrifugal pump as an example):Prerequisites, processes, and requirements for the overall system structure.
