基于Kriging模型的气液两相离心泵优化设计
Optimization design of gas-liquid two-phase centrifugal pump based on Kriging model
摘要
Abstract
In order to improve the head and efficiency of high-speed centrifugal pump under gas-liquid two-phase conditions,the high-speed centrifugal pump model Q5H26 was taken as the research object.The effects of different gas content(volume fraction)on the performance of centrifugal pump were analyzed.The results show that the larger the gas content,the lower the head and the efficiency.The parameters of the worm gear and the impeller of the centrifugal pump were analyzed comprehensively and sensitively based on the Kriging model.In order to improve the operating efficiency and head,the parameters of the high-speed centrifugal pump were optimized using the NLPQL algorithm under the gas-liquid two-phase conditions.The numerical simulation of the optimized model was carried out,and the operation efficiency and head of the model pump before and after optimization were compared by experiments.The results show that in the rated working condition,the gas content rate of 10％,the optimized model pump efficiency is increased by 8％,the head is increased by 1.5 m,and the optimization effect is more significant.The results can provide an effective method for improving the performance of the high-speed centrifugal pumps under the conditions of gas-liquid two-phase.关键词
