Secondary water supply system and water supply method
The invention belongs to the technical field of secondary water supply, and particularly relates to a secondary water supply system and a water supply method.The secondary water supply system is used for solving the technical problem that the energy-saving effect is poorer, in the secondary water supply system, a municipal pipe network pipeline, a water storage tank, a pressure dynamic simulation unit and a user pipe network pipeline are sequentially communicated, and the municipal pipe network pipeline is further communicated with the user pipe network pipeline; the full frequency conversion controller is connected with a first pressure acquisition unit on a municipal pipe network pipeline, a water storage valve on a water storage pipeline, a second pressure acquisition unit on a user pipe network pipeline and a pump set in a pressure dynamic simulation unit. The full-frequency-conversion controller controls the opening degree of the water storage valve and the frequency of the pump set according to first data of the first pressure collecting unit and second data of the second pressure collecting unit, on one hand, the pump set always operates in a high-efficiency area, on the other hand, incoming water pressure fluctuation interference is reduced, the pipeline pressure of a user pipe network is kept constant, and water supply energy consumption is reduced. And the energy-saving effect is good.
本发明属于二次供水技术领域，具体涉及一种二次供水系统及供水方法，用于解决节能效果较差的技术问题，该二次供水系统中，市政管网管路、储水箱、压力动态模拟机组、用户管网管路依次连通，且市政管网管路还与用户管网管路连通，全变频控制器与市政管网管路上的第一压力采集单元、储水管路上的储水阀门、用户管网管路上的第二压力采集单元和压力动态模拟机组中的泵组均连接，全变频控制器根据第一压力采集单元的第一数据和第二压力采集单元的第二数据控制储水阀门的开启度和泵组的频率，一方面使泵组始终在较高效率区运行，另一方面减少来水压力波动干扰，维持用户管网管路压力恒定，降低供水能耗，节能效果较好。
