The control core of the fully variable frequency water supply system is the pump frequency converter. The principle is that the controller automatically adjusts the pump speed according to the target pressure set by the user, and controls the flow stabilization system pressure. The system can automatically adjust the number of pump operations according to the size of the water consumption, automatic timing rotation, can achieve water operation, water suspension and sleep, energy saving effect is remarkable, each pump is a soft start soft stop, reduce the impact on the power grid pipe network, prolong the service life of the system. With external expansion, optional host computer monitoring, etc., intelligent and reliable, is the development direction of today's water supply applications.

The servo controller is controlled by using accurate photoelectric detection, so that the coil can be corrected at any time to maintain a neat and correct position, also known as a correction device. It is widely used in various types of industrial machinery, can improve quality, reduce loss and reduce manpower, is the behind-the-scenes credit of industrial automation.

The role of the controller series is mainly to achieve synchronization between rollers, uniform control of winding and unwinding. Its working principle can be divided into open loop, closed loop or free loop control system according to the loop; According to the monitoring method of different coils, it can be divided into ultrasonic type, floating roller type, tracking arm type and other control systems. The entire system consists mainly of controllers, detectors, brakes and clutches. The system is divided into direct control and indirect control. The control mode is manual control, semi-automatic mode, fully automatic and so on.
