3BHB021400R0002 5SHY4045L0004 The basic control strategy of constant-pressure water supply is to use programmable controller (plc) and frequency conversion speed control device to form a control system to optimize the speed control of the pumping unit and automatically adjust the number of pumping units, to complete the closed-loop control of the water supply pressure, i.e., to adjust the rotational speed of the pump motor and the number of pumps automatically according to the actual set water pressure to ensure that the pressure in the water supply network remains at the set value, which can not only meet the production water supply requirements, but also save electricity. That is to say, according to the actual set water pressure, the speed of water pump motor and the number of water pumps are adjusted automatically to compensate for the change of water consumption, so as to ensure that the pressure of water supply pipeline network is kept at the set value, which can not only satisfy the requirements of production water supply, but also save electric power, make the system in a reliable working state, and realize the constant-pressure water supply.

3BHB021400R0002 5SHY4045L0004 frequency conversion speed constant pressure water supply system consists of frequency converter, pump motor, water supply network, water storage tank, intelligent pid regulator, pressure transmitter, plc control unit and other parts, the role of the frequency converter is to provide the motor with variable frequency power supply, to achieve stepless speed regulation of the motor, so as to make the pipe network water pressure continuous change, at the same time, the frequency converter can also be used as a motor soft start-up motor, to ensure that the system is in a reliable working condition, to achieve constant pressure water supply. The frequency converter can also be used as a motor soft start device to limit the starting current of the motor.
