Lüliang Box-type Superposed Pressure Boosting Water Supply Equipment

Lüliang Box-type Superposed Pressure Boosting Water Supply Equipment can eliminate the water hammer effect during startup and shutdown. The price of the water supply equipment, along with its stable and safe operational performance, simple and convenient operation, and comprehensive functions, will enable water supply to achieve water saving, electricity saving, and labor saving, ultimately achieving high-efficiency operation. In terms of frequency conversion application methods, multiple common pumps are usually set up in the same water supply system. When the water supply demand is high, multiple pumps are fully activated; when the demand is low, one or two pumps are activated. When using frequency conversion constant pressure water supply equipment for constant pressure water supply, two methods are employed.

Lüliang Box-type Superposed Pressure Boosting Water Supply Equipment: The first method involves equipping all water pumps with one frequency converter; the second method involves equipping each water pump with a frequency converter. The latter method, based on pressure feedback signals, automatically adjusts the output frequency of the frequency converter through PID calculation, changes the motor speed, and ultimately achieves the goal of constant pressure in the pipeline network. This forms a closed-loop system, which is relatively simple but costly. The former method is cost-effective and performs no worse than the latter, but the control program is more complex and represents the future development direction.

With the development of power technology and the continuous improvement of frequency conversion speed regulation technology, intelligent fully automatic frequency conversion water supply complete equipment, centered on frequency conversion speed regulation, has replaced previous water supply equipment such as high-level water tanks and pressure tanks. It starts smoothly, with the starting current limited to within the rated current, thereby avoiding impact on the power grid during startup. Since the average speed of the pump is reduced, the service life of the pump, valves, and other components can be extended.
