Users’ water consumption is generally dynamic, so water shortage or excess water situation occurs. And the imbalance between water and water is reflected in the water supply pressure, that is, water and water supply less, the pressure is low; water and water supply more, the pressure is large. Maintain the constant water supply pressure, so that water and water can be maintained between the balance, that is, water supply for many times, less water when the water is less, thus improving the quality of water supply.
Constant pressure water supply system is very 
important for users. In the production of domestic water supply, if the water supply for some reason or lack of water, may affect the quality of life, serious will affect the safety of survival, such as the occurrence of fire, if the water supply is insufficient or water supply, can not fire, Causing significant economic losses and casualties. Therefore, the water area is used constant pressure water supply system, can produce greater economic and social benefits.
With the development of power technology, frequency control technology is improving, with frequency control as the core of the intelligent water supply control system to replace the previous high water tank and pressure tank and other water supply equipment, starting smooth, starting current can be limited to within the rated current, Thus avoiding the impact of the start of the power grid; the average speed of the centrifugal pump is reduced, which can extend the life of pumps and valves and other things; can eliminate the start and stop when the water hammer effect. Its stable and safe operation performance, simple and convenient mode of operation, and complete and thoughtful function, will make water supply to achieve water, energy saving, saving manpower, and ultimately achieve efficient operation purposes.
