This video describes the major parts and function of a centrifugal pump with a diffuser design and multi vane impeller.
In centrifugal pump technology, diffusers are frequently used on the discharge side of ring-section and volute casing pumps (see Pump casing), they are also used in multistage centrifugal pumps and as a component in piping runs.
There two basic types of pump casings: volutes and diffusers. Whether we’re talking about volutes or diffusers, what all casings have in common is that they are designed to take energy in the form of velocity and convert it into pressure. Volutes Image from A Brief Introduction to Centrifugal Pumps by Joe Evans, Ph.D
In a centrifugal pump design, shaft diameter and bearing size can be affected by allowable deflection as determined by shaft span, impeller weight, radial reaction forces, and the torque to be transmitted.
In this study, multi-parameter optimization of the diffuser of a volute centrifugal pump was carried out using the combination of Latin hypercubic sampling, ANN, and NSGA-II. The optimized model exhibited varying degrees of improvement under three operating conditions.
3 lut 2020 · Based on this, the effects of critical geometrical parameters (e.g. the wrap angle and the array position of the diffuser vane) of the diffuser on pump performance are investigated by a CFD code for an intuitive understanding of improving the performance of the centrifugal-flow pump.
