摘要
为保证水泵安全运行,结合实例提出,水泵并联运行时,计算的轴功率应能满足排水系统多种运行工况,依据最不利工况选配电动机。为确定最佳排水方案,排水设备选型在进行技术经济比较时,不仅需要核算排水设备投资费用,还应考虑吸水高度对水仓设计及基建投资的影响。
In order to ensure the safe operation of the water pump, the paper took the example to propose： the calculated shaft power should meet the demands of drainage system in various operation modes while the water pumps operated in parallel; the motor should be selected according to the severest operation mode. To determine the optimal drainage scheme, while the drainage facilities were contrasted in their technical economy, not only the investment cost of the drainage facilities needed to check, but the influence of suction height on the water sump and the infrastructure investment should be considered.
