串极调速装置在水厂的应用为了节约能源，降低成本（由于电价不断的提高，电费已占制水成本的４５％以上），解决现有水泵扬程过高（按最高日最高时设计）；加上供水管道口径扩大调整、原水水质恶化，原有的净水设备达不到设计要求和城市用水量大大超过水厂的设备能力，造... The application of the cascade speed governor in the water plant saves energy and reduces costs (Since electricity prices continue to increase, electricity costs already account for more than 45% of the cost of water production), the existing water pump head is too high (designed at the highest daily maximum) In addition, the adjustment of the diameter of the water supply pipeline and the deterioration of the raw water quality have prevented the original water purification equipment from meeting the design requirements and the urban water consumption has greatly exceeded the equipment capacity of the water plant.
