Energy-saving constant-pressure water supply system
The invention belongs to the technical field of water supply control, and discloses an energy-saving constant-pressure water supply system which comprises a constant-pressure water supply control module, an energy-saving control module, a water tower, a normal-temperature water tank, a heat preservation water tank, a cooling-water machine and two water pump units. Each water pump is provided with an independent frequency converter and a sensor for control; the constant-pressure water supply control module performs PID calculation in real time based on pipeline water pressure and target pressure, and determines the output frequency of a frequency converter of the water pump to control the water pump to operate; and the energy-saving control module continuously monitors that the pipeline water pressure is kept at the target pressure and the output frequency of the frequency converter of the water pump is at the lower limit frequency for a first preset duration, stops operation of the water pump and the frequency converter of the water pump, and starts the water pump and the frequency converter of the water pump until the pipeline water pressure is monitored to drop from the target pressure to the first preset pressure. The constant-pressure water supply device can automatically operate and efficiently supply water at constant pressure in an energy-saving manner.
本申请属于供水控制的技术领域，公开了一种节能恒压供水系统，该系统包括：恒压供水控制模块以及节能控制模块、水塔、常温水箱、保温水箱、冷水机以及两个水泵机组，每个水泵机组包括两个常用水泵与一个备用水泵，每个水泵都配有单独变频器与传感器进行控制；恒压供水控制模块基于管路水压和目标压力实时进行PID计算，确定水泵的变频器输出频率以控制水泵运行；节能控制模块持续第一预设时长监测到管路水压保持在目标压力且水泵的变频器输出频率处于下限频率，停止水泵和水泵的变频器运行，直至监测到管路水压从目标压力下降至第一预设压力时，启动水泵和水泵的变频器。本申请可自动运行且高效节能地恒压供水。
