摘要
Abstract
Taking a relay pumping station as an example,the output capacity of multiple pumps in par-allel and the pump selection method are analyzed.The reason for the left shift of the water pump working point and insufficient flow rate is due to excessive system re-sistance.After the renovation,the working characteris-tics of the pump are coordinated with the resistance characteristics of the pipeline,and each pump works in the high-efficiency area.The flow margin coefficient of the recommended selection method is 1.05-1.10.The conventional selection method excessively consid-ers the influence of the number of parallel pumps on the flow margin coefficient,resulting in excessively large flow margin coefficient selection.Compared with the conventional selection method,the multi-pump par-allel system selected according to the recommended se-lection method can reduce the total power consumption and improve the overall efficiency.关键词
