Description
技术领域technical field

背景技术Background technique
传统的供水设备是采用一台变频器控制多台水泵运行，通常在同一路供水系统中，设置多台常用泵，当供水量大时多台泵全开，供水量小时开一台或两台。多台水泵递次软启动将启动电流从零开始，高峰时加泵，当变频泵达不到设定压力，变频泵顺势转工频，启动下一台泵变频运行。低峰减泵，在用水量小时，自动减泵，但是泵工作在工频时，会出现“大马拉小车”的情况，节能效果并不是很好，供水耗能高。Traditional water supply equipment uses a frequency converter to control the operation of multiple water pumps. Usually, multiple common pumps are installed in the same water supply system. When the water supply is large, multiple pumps are fully activated, and when the water supply is small, one or two pumps are turned on. . The soft start of multiple pumps will start the current from zero, and the pump will be added at the peak time. When the variable frequency pump cannot reach the set pressure, the variable frequency pump will switch to industrial frequency and start the next pump to run at variable frequency. Low-peak pump reduction, when the water consumption is small, the pump will be automatically reduced, but when the pump works at power frequency, there will be a situation of "big horse-drawn carts", the energy-saving effect is not very good, and the energy consumption of water supply is high.
