The LG automatic high-rise heating vector pressure regulating water supply equipment is designed for efficient and stable water distribution in tall buildings. It features variable flow control that adapts to external network pressure fluctuations, ensuring consistent water pressure at the high zone. When user demand changes due to sub-metering or other factors, the system automatically adjusts the heating flow while maintaining backwater consistency with the external network. This ensures no interference between the high and low zones, keeping the low zone operating safely and efficiently. The system is energy-efficient, cost-effective, and ideal for complex building environments such as basements, mountainous areas, and industrial sites.
Features
High efficiency and energy-saving, constant water pressure, complete functions, programmable control, reliable operation, easy to use, strong protection system, long service life, and strong resistance to interference. This system is perfect for both residential and commercial applications, offering a compact design with high automation levels.
Applications
Suitable for urban and rural water pumping stations, gas stations, residential areas, hotels, restaurants, large public buildings, industrial and mining production, domestic water systems, heating and air conditioning circulation systems, agricultural irrigation, drainage, sprinkler systems, and musical fountains. The LG system provides flexible and reliable solutions for various water supply needs.

Working Principle
The pressure sensor or flowmeter converts signals into electrical signals, which are then sent to the automatic control box. After processing, the signal is fed back to the inverter, which adjusts the motor speed by changing the frequency. This allows the pump to adjust its operation in real time, maintaining a constant water pressure at a set point and adjusting the flow rate based on water demand. This not only saves energy but also ensures safe and reliable performance.
The system uses multiple pumps connected in parallel. When water consumption is less than or equal to the flow of one pump, the variable frequency pump starts. As usage increases beyond this, 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 also includes a pressure pump or pressure tank. When water usage is minimal, the pressure tank stores pressurized water to maintain system pressure, allowing the variable frequency pump to stop, further enhancing energy savings. The system consists of one to four main pumps, a constant pressure pump (or pressure tank), water mains, valves, automation instruments, and an automatic frequency conversion control box, making it easy to install and compact. Each unit undergoes rigorous factory testing to ensure stable and reliable performance.
