基于响应面高维代理模型的双吸式离心泵优化设计
Optimization design of double-suction centrifugal pumps based on response surface high-dimensional surrogate models
摘要
Abstract
To improve the efficiency of double-suction centrifugal pumps,this study optimizes the impeller design for a specific water intake pump.Key parameters such as the inlet and outlet installation angles of the rear and front cover plates(β1h,β1s,β2h,β2s)and the blade wrap angle(φ)were systematically varied.Geometric reconstructions of the impeller were made within these parameter ranges to create a training dataset,and a high-dimensional surrogate model based on response surface methodology was developed,and the reliability of the model was verified by comparing the numerical simulation results and experimental results of the optimized double suction pump head and efficiency.The results show that the optimized impeller enhanced flow distribution,reduced turbulence at the inlet,and increased outlet velocity,resulting in approximately 3%efficiency improvement,especially notable at the pressure chamber outlet.Efficiency gains of over 3%were observed at flow rates of 0.7Qd,0.8Qd,0.9Qd,and Qd,with the greatest head increase of about 0.8 m at 0.7Qd and 0.8Qd.This optimization extends the high-efficiency range of the pump and provides an effective method for impeller design.关键词
