以串联泵的联合运行为例，探讨了4种典型的串联泵控制方案，并基于 Simulink ／SimHydraulics搭建实物模型进行仿真实验和对比分析，最终说明节流控制虽具有较佳的调控性能和安全性能，但耗能严重；变频控制虽然具有高效节能的优点，但存在调控速率慢和低流量时压头过低而影响后续流程的问题；而分程控制能够满足管路控制点所需压力和流量的要求，在保证调控性能和安全性能的同时节能效果显著，控制方案可行并具有较高的实用价值。

Taking the combined operation of centrifugal pumps in series as an example,the four special con-trol schemes for the pumps in series were discussed and the model for them was built based on Simulink /Sim-Hydraulics.The simulation result indicates the the throttle control asks for more energy consumption but it boasts better control performance and higher safety;and VFC’s (variable frequency control)advantages in the energy-efficiency and its shortcomings of slower regulation rate and lower pressure head which influencing the follow-up flow;and the split-ranging coordinated control can satisfy the pipeline control points’requirements for both flow rate and pressure.This control strategy has practicability and obvious energy-saving effect besides its remarkable regulation performance and safety.
