| 摘要: |
| 针对横加法确定水泵并联运行工作点的不足，通过对并联系统各水泵装置的能量供需情况及其水力特性的分析，推导出了利用能量方程确定水泵并联运行工作点的新方法。用此方法可直接确定系统各部分流量、扬程、水位及水头损失之间的关系。 |

| Abstract: |
| Targeting at the shortcomings in horizontal additivity method of operating point determination of pumps in parallel,the energy supply-demand and hydraulic characteristic of each pumping system of pumps in parallel are analyzed.The new method to determine operating point of pumps in parallel is derived by the use of the energy equation.The relation among capacity,head,water level and hydraulic loss of each pumping system can be determined directly by this method. |
| Key words: pump operating of pumps in parallel operating point determination |
