Water pump and/or blower fan highly effective energy-conserving control system

The utility model relates to a high-efficiency and energy-saving controlling system applied to a water pump and/or a fan. The system comprises a energy-consumption user end, a working part formed by the water pump and the fan, a matching intelligent controllable dynamic device formed by a motor, a motor protector, a frequency converter, a soft starting device and a pulse starting device, and a system managing part formed by a programmable controller, a touch-screen display and a sensor. The working part and the user end are connected by a matching pipeline, and the managing part collects the return paths of the online liquid parameters by the sensor, transmits the controlling signals to a servomechanism of the controllable dynamic device after comparing processing to form closed loop controlling. A pressure sensor and a flow sensor are respectively arranged at each node between the working part and the user end, wherein the online signals collected by the pressure sensor and the flow sensor are processed to b
