Project Introduction
1、 Product Overview:
The variable frequency water supply control cabinet is based on an intelligent controller, which sets the pressure through a human-machine interface and dynamically displays the working status of each pump on site. Realize stepless speed regulation through a frequency converter, and precisely control the constant water supply pressure according to the changes in water consumption. The frequency conversion control cabinet consists of a cabinet body and a frequency converter, PLC、 Composed of touch screen, air switch, contactor, circuit breaker, intermediate relay, etc. It has the characteristics of easy operation, high degree of automation, high reliability, unmanned operation, and remote visual control.
2、 Product Description:
1. Control function: The variable frequency water supply control cabinet has functions such as overcurrent, overvoltage, undervoltage, overload, overheating, fault self diagnosis alarm, low water level protection, timed operation switching, alternating operation, preventing water pump from idling, running over faulty pumps, timed operation, timed inspection, water shortage shutdown, and unused water sleep.
2. Control mode: automatic/manual.
3. Number of control units: single, double, or multiple group controls (usually able to parallel 2-6 water pumps)
4. Starting method: Variable frequency soft start.
5. Control requirements: time, temperature, pressure, liquid level, flow rate.
6. Remote control: Computer or mobile remote monitoring system.
3、 Technical specifications:
1、 0.75KW--315KW
2. Variable frequency drive
3. LCD display screen, PLC, PID control.
4. RS485 communication function, easy to connect with the upper computer for configuration control.
4、 Variable frequency system
PLC - Programmable Logic Controller
The main functions of PLC application in constant pressure water supply control system are: collecting analog signals, PID control, PLC programming software combined with frequency converter control, using software to collect analog signals to control frequency size, and controlling according to the set pressure. The application process in constant pressure water supply process is as follows:
