Variable frequency constant pressure water supply equipment is a common pump control system, which is used to keep the water pressure stable and automatically adjust the working state of the pump according to the actual demand. The regulation control system plays a key role, which is based on the feedback signal of the sensor, and realizes the precise control of the pump by controlling the frequency converter.
The working principle of the regulation control system is as follows:
The pressure sensor in the system monitors the pressure of the water supply line in real time. When the pressure drops below the set value, the sensor sends a signal.
This signal is passed to the inverter, which adjusts the output frequency according to this signal. By adjusting the frequency, the inverter can change the operating speed of the pump, thus controlling the pressure of the water supply.
The frequency converter transmits the adjusted frequency to the pump. According to the instructions of the inverter, the water pump adjusts the speed of the motor to realize the adjustment of the flow rate.
After the water supply line reaches a preset pressure set point, the pressure sensor stops signaling. The inverter keeps the operating state of the pump at a stable working point by controlling the frequency of the pump.
Regulation control systems are also usually equipped with various protection functions, such as overload protection, overvoltage protection and current protection. When there is an abnormal situation, the system will automatically cut off the power supply to prevent damage to the device.
The design and parameterization of the control system are very important. The system adjusts the frequency of the pumps precisely according to the demand for water supply to avoid over- or under-supply of water and to maintain a constant water pressure. In addition, the regulation control system should be regularly maintained and calibrated according to the actual situation to ensure the normal operation and stable performance of the system.
The regulation and control system of the variable frequency constant pressure water supply equipment controls the frequency of the inverter to change the frequency of the water pump through the sensor feedback signal, so as to realize the adjustment of the flow rate of the water pump to maintain a stable water supply pressure. This state-of-the-art control system can improve the efficiency and performance of water supply equipment and meet the user's demand for constant water pressure.
