In the embodiment, the fan frequency converter and the water pump frequency converter adopt the Yingweiteng Goodrive200A series frequency converter, and the energy conservation of the frequency converters is mainly shown in the application of a fan and a water pump. After the variable frequency speed regulation is adopted for the loads of the fan and the water pump, the power saving rate is 20-60 percent, because the actual power consumption of the loads of the fan and the pump is basically proportional to the third power of the rotating speed. When the average flow required by a user is small, the rotating speed of the fan and the pump is reduced by adopting variable frequency speed regulation, and the energy-saving effect is very obvious. The traditional fans and pumps adopt baffles and valves to adjust the flow, the rotating speed of the motor is basically unchanged, and the power consumption is not changed greatly. The frequency setting mode common to frequency converters can also be achieved by: the method comprises the steps of operator keyboard setting, contact signal setting, analog quantity signal setting, pulse signal setting, communication mode setting and the like. The frequency setting modes have advantages and disadvantages, and the control mode of the system adopts an analog quantity mode to set the frequency.

When the oil temperature F fed back by the F and A is greater than the temperature value A set by a human-machine interface (HMI), the PLC outputs analog quantity until the frequency converter is gradually increased to 50HZ operation frequency from the current operation frequency, the cooling water flow is increased, the real-time feedback oil temperature is gradually reduced, and positive gain output is performed at the moment; when the feedback oil temperature F is less than the temperature value A set by a human-machine interface (HMI), the PLC outputs analog quantity until the frequency converter gradually decreases from the current operating frequency to the 0HZ operating frequency, the cooling water flow decreases, the feedback temperature gradually increases, and the negative gain output is performed at the moment.
