The LG Automatic High-Rise Heating Variable Flow Pressure Regulating Water Supply Equipment is designed for efficient and stable water supply in high-rise buildings. It features variable flow control, which allows the system to adjust automatically based on external network pressure and flow changes, ensuring consistent pressure throughout the high zone. When user demand fluctuates due to sub-metering or other factors, the equipment adjusts heating flow accordingly while maintaining stable backflow from the external network. This ensures that the low zone remains unaffected, guaranteeing safe and reliable operation with lower energy consumption and running costs.
Key advantages include low investment cost, unattended operation, smooth performance, easy installation, a small footprint, and a high degree of automation. It is ideal for basement complexes, high-rise buildings with large elevation differences, coal warehouses in thermal power plants, and more. The product comes with detailed technical specifications and has been tested for stability and reliability before leaving the factory.

Principle
Pressure sensors or flow meters convert signals into electrical input for the automatic control box. After processing, the signal is fed back to the inverter, which adjusts the frequency to control the motor speed, thereby adjusting the pump flow to maintain constant pressure at a specific point. This not only saves energy but also ensures safe and stable operation.
The system connects multiple pumps in parallel. When water usage is less than or equal to the flow of one pump, the variable frequency pump starts working. As usage increases beyond this level, additional pumps are activated while the variable frequency pump regulates the flow. When usage decreases, the frequency pumps are turned off one by one until only the variable frequency pump remains active.
The unit is equipped with a pressure pump or tank. When water demand is low, the pressure tank or pump provides pressurized water to maintain the system, allowing the variable frequency pump to stop, further improving energy efficiency. The system includes one to four main pumps, a constant pressure pump (or tank), pipelines, valves, automation instruments, and an automatic frequency conversion control box, making it compact and easy to install. Rigorous testing ensures stable performance upon delivery.
