Application mode of variable frequency constant pressure water supply
Application mode of variable frequency constant pressure water supply
In the field of industrial field control, programmable logic controller (PLC) has always played an important role. With the increase of national investment in the water supply industry, the automation level of water plant operation is constantly improving, and the application of PLC in the water supply industry is gradually increasing. The touch screen is used together with PLC, which makes the application of PLC more flexible. At the same time, it can set parameters, display data, describe the automatic process with animation and other situations, and make the application of PLC visible.
Variable frequency constant pressure water supply has become a mainstream of the water supply industry, and is an important means to ensure that the water supply network is in a constant pressure state. The perfect network communication function of modern frequency converter provides necessary support for synchronous operation of motor, remote centralized control and online monitoring. The touch screen connected with PLC can make the control more visual and intuitive, and the operation more simple and convenient.
PLC, touch screen and frequency converter are combined to control the frequency converter by means of communication to realize frequency conversion and constant pressure water supply.
