200V Digital Water Power Supply Frequency Cabinet Constant Pressure

The Constant Pressure Water Supply Energy-Saving Cabinet is a dedicated energy-efficient control device designed for water supply systems. It intelligently adjusts the operating status of water pumps to achieve constant pressure water supply and energy conservation.

1. Pressure Monitoring and Regulation
   Pressure sensors monitor the pipeline pressure in real time and transmit data to the PLC controller. The controller automatically adjusts the output frequency of the frequency converter based on the deviation between the set pressure value and the actual pressure value, thereby controlling the pump speed to maintain constant pipeline pressure.
2. Multi-Pump Coordinated Control
   The system can control multiple water pumps (e.g., 3 main pumps + 1 small pump) and automatically switch pump operation modes according to water demand. During low water demand, the small pump or a single main pump operates; during high water demand, multiple main pumps operate in tandem to meet demand.

1. High Energy Efficiency
   • Adopts frequency conversion speed regulation technology to automatically adjust pump speed according to water demand, avoiding full-load operation and reducing power consumption.
   • Compared to traditional water supply methods, energy savings can reach 25%-50%.
2. Stable Water Pressure
   • Eliminates issues of insufficient water supply or excessive pressure caused by pressure fluctuations, ensuring stable water pressure at the user end.
3. Extended Equipment Lifespan
   • Soft start function reduces the inrush current during pump startup, minimizing mechanical wear and extending the service life of the pump.
   • Timed pump switching function balances the working hours of each pump to prevent overloading of a single pump.
4. Intelligent Protection and Alarm
   • Equipped with alarm functions for overpressure, low water level, sensor disconnection, and frequency converter failure, ensuring safe system operation.
   • Fault automatic reset mechanism and fault query function facilitate maintenance.
5. Remote Control and Automation
   • Supports remote monitoring and control via mobile phones and computers, enabling fully automated operation without manual supervision.

1. Significant Energy Savings
   Compared to traditional water supply methods, energy savings can reach 25%-50%, reducing operating costs.
2. Improved Water Supply Efficiency
   Automatically adjusts pump operation based on water demand, avoiding water waste and improving water quality.
3. Enhanced System Reliability
   • Automatically monitors pump status and adjusts pump speed based on real-time pressure, ensuring stable water supply and on-demand delivery.

1. Flexible Configuration
   • Each pump can be set as a variable or fixed-speed pump, meeting complex supply system needs.
   • Supports 8-time pressure settings, enabling precise control over pump speed and pressure.

• Urban Planning :The energy-saving cabinet is not a substitute but can be integrated into water supply systems to achieve similar energy-saving goals, such as the air compressor energy-saving cabinet in this text.
