摘要
通过分析得出了一次泵宜采用变频调节;为避免供水环路水力失衡,变频二次泵应设最低频率限制;提出变频二次泵应多台并联供水以满足系统低负荷时的水量需求,同时提出动态压力点控制法。
Recommends that the primary water systems adopt variable frequency pumps.Presents that the minimum frequency should be set for secondary water pumps with variable frequency to avoid hydraulic imbalance in water supply loops,and that the secondary water pumps should be installed in parallel to satisfy the water rate demand of partial load.Puts forward the control method of dynamic pressure point.
