A constant-pressure water supply system is essential for applications where stable water pressure directly affects performance and reliability. In traditional pump systems, fixed-speed motors or manual valve adjustments often lead to pressure fluctuations, higher energy consumption, and increased mechanical wear. By using the GK3000 upgraded Variable Frequency Drive with built-in PID control, a fully automated pump control solution can be implemented. Combined with a pressure sensor, the system automatically regulates pump speed to maintain stable water pressure under varying load conditions. This article provides a complete guide to the system architecture, wiring method, parameter configuration, and commissioning process for a GK3000-based constant-pressure water supply system.

Servo Drive System and Variable Frequency Drive are two different types of drive systems, which have different applications and characteristics in the field of industrial automation. ATO online shop will go into detail about this topic.
VFD (Variable-frequency Drive) is widely used in industrial automation field to improve industrial production efficiency and save business cost. It is a kind of power control equipment to control AC motor by changing the working frequency of motor, which can realize the functions of soft starting, variable frequency speed regulation, improving the running accuracy, changing power factor, over-current/over-voltage/overload protection for AC asynchronous motor.
Customized equipment, also known as non-standard equipment, is a type of integrated automated equipment that is specifically designed as customers desire and not circulating on the market. In this video, we’re gonna show you a non-enclosure VFD that is specially built for custom-made equipment.
The variable frequency constant pressure water supply system takes the water pressure of the pipe network (or the user's water flow) as the setting parameter, and uses the pressure sensor to measure the water pressure in the water supply system, and then the pressure sensor will detect the signal 0-10V or 4~20ma signal. It is transmitted to the PID loop of the VFD, and after the VFD PID processing, the running speed of the water pump is adjusted according to the output frequency signal of the variable frequency drive, so as to realize the closed-loop automatic adjustment of the water pressure of the pipe network, so that the water pressure of the pipe network of the water supply system can be adjusted according to the setting.
A variable-frequency drive (VFD) is a type of motor drive used in electro-mechanical drive systems to control AC motor speed and torque by varying motor input frequency and, depending on topology, to control associated voltage or current variation. VFDs can be used to control AC motor speeds by changing the motor's frequency without sacrificing the output power of the motor. This is done by turning the speed pot (explained in section three) of an AC motor drive.
An induction motor is similar to a poly-phase transformer whose secondary is short circuited. Thus, at normal supply voltage, like in transformers, the initial current taken by the primary is very large for a short while. Unlike in DC motors, large current at starting is due to the absence of back emf. If an induction motor is directly switched on from the supply, it takes 5 to 7 times its full load current and develops a torque which is only 1.5 to 2.5 times the full load torque. This large starting current produces a large voltage drop in the line, which may affect the operation of other devices connected to the same line. Hence, it is not advisable to start induction motors of higher ratings (generally above 25kW) directly from the mains supply.
The working principle of the constant pressure water pump is as follows:
- The VFD drives the water pump, and the pressure sensor/transmitter feeds back the pressure signal to the VFD to form a closed loop system.
- When the water pipe pressure is less than the set value, the VFD wakes up and starts pumping water.
- When the pressure does not reach the set target, the operating frequency will continue to increase to the rated frequency of the pump.
- When the pressure is greater than the set pressure, the operating frequency will decrease.
- When the pressure is greater than the sleep pressure, the frequency decreases to the sleep frequency for a period of time, and then stops pumping water.
- When the pressure is lower than the wake-up pressure, the pump starts to run again.
Generally, using PLC as an intermediate tool for HMI to control VFD is a good choice. Now, let’s us establish and HMI to control the VFD project. We need to communicate with an Omron PLC and use the PLC commands to control the VFD. Set the PLC model and communication parameters (RS232, Host Link communication protocol) that need to be communicated.
A programmable logic controller (PLC) or programmable controller is an industrial computer that has been ruggedized and adapted for the control of manufacturing processes, such as assembly lines, machines, robotic devices, or any activity that requires high reliability, ease of programming, and process fault diagnosis. A variable-frequency drive (VFD) is a type of motor drive used in electro-mechanical drive systems to control AC motor speed and torque by varying motor input frequency and, depending on topology, to control associated voltage or current variation.
