Low specific speed centrifugal pumps typically suffer from low efficiency and severe backflow; adding optimally structured splitter blades can play a role. In this paper, the distribution of pressure velocity in flow channel is analyzed using CFD simulation for pump. The geometric parameters blade are optimized an orthogonal test artificial fish swarm algorithm; then optimal structure obtained. Results showed that not only effectively solves backflow compresses range trailing vortex, but it...
Measuring geometric properties for large-sized parts is faced with various challenges. This study established a novel method measuring the flatness of large-scale annular workpieces, flange wind turbine tower as an example. The proposed based on three-dimensional (3D) machine vision and precision motion control technology, aiming to address issues such distorted measurements, long measurement times, significant safety risks. primarily focused development algorithms workpieces through...
In order to determine the optimal structural parameters of a plastic centrifugal pump in framework an orthogonal-experiment approach, numerical study related flow field has been performed using CFX. The thickness S, outlet angle β2, inlet β1, wrap angle, and diameter D1 splitter blades have considered as variable factors, shaft power efficiency evaluation indices. Through parametric analysis, relative importance influence each parameter on index obtained, leading following combinations: β1...
The structural design parameters of a plastic centrifugal pump were calculated and modeled, flow field simulation analysis the model was performed using CFD, in framework an orthogonal method (or experiment). inlet mounting angle β1, outlet β2, wrap ϕ, impeller diameter D1 four factors assumed for application experiment, efficiency Net Positive Suction Head (NPSH) as evaluation indices. Moreover, taking maximum minimum NPSH factors, re-optimized through Taguchi algorithm (leading to...
