Impeller design theory
Witryna7 lut 1983 · Impellers are selected based on aerodynamic performance and mechanical integrity. Mechanical integrity is typically evaluated by finite element analysis (FEA), while aerodynamic performance is evaluated by a combination of one-dimensional (1D) and computational fluid dynamic (CFD) tools. WitrynaFigure 1 is a simplified diagram of a typical centrifugal pump that shows the relative locations of the pump suction, impeller, volute, and discharge. The pump casing …

Witryna13 kwi 2024 · Shi et al. ( Shi et al., 2024a) designed an axial-flow pump impeller based on the surface element method, and studied the influence of the impeller rotor on the hydraulic performance of the all-tube pump, and found that the reduction of the maximum running head of the all-tube pump was greater than that of the axial flow pump.
Witryna17 sie 2024 · The impeller is the rotating part, and the casing is the airtight path that surrounds the impeller. The fluid in a centrifugal pump enters the casing, falls on the impeller vanes at the impeller eye, and rotates radially outward until it exits the impeller through the diffuser (volute) of the casing. Witryna23 maj 2024 · Starting with the design specifications, a preliminary design for the first stage suction bowl, impeller and diffuser was created in the turbomachinery design package CFTturbo® as shown in Fig. 1. The initial inputs consist of global parameters which include the design flow, speed, fluid, rotation, estimated case efficiency, and …
