Automatic frequency conversion constant pressure water supply equipment, is a kind of ideal energy-saving water supply equipment, energy-saving effect is good, compact structure, cover an area of an area small, stable and reliable operation, long service life, design flexible, adjustable supply pressure, flow rate but can small, can completely replace the water tower, high water tank and various kinds of pneumatic water supply equipment,The secondary pollution of water quality can be completely eliminated.Automatic frequency conversion and constant pressure water supply equipment is also used to transform the original old pumping house equipment, after the transformation can also achieve the purpose of high efficiency and energy saving, automatic constant pressure water supply.

The basic basis of choosing a set of automatic water supply equipment is the design of water supply flow and water supply pressure (head of water), but also need to take into account the use of flow change type.

Continuous type: a day when the flow is rarely zero, or the normal leakage of its own pipe network to maintain a certain flow, for example, large hotels, hotels, industrial and mining enterprises pressure system.

Intermittent type: water trough time is long and the flow is small or zero, for example: small office buildings, office buildings, commercial and residential buildings, all kinds of residential, and production water, etc. At the same time, should also consider the change of the flow of water in a certain period of time, as well as the change of the flow in different seasons, different areas of water and other factors.

Fire water supply equipment and spray water supply equipment should generally choose pneumatic water supply equipment, because of its long-term in the system pressure holding state, no flow change, pneumatic water supply equipment can deal with the general leakage in the pipe, and increase a small flow of the auxiliary pump, usually without starting the main pump, save energy.

Life water supply equipment to choose frequency conversion water supply equipment or pneumatic water supply equipment can be, both have their own advantages.

The advantage of frequency conversion water supply equipment, constant pressure water supply and constant pressure value within a certain range, generally less than 0.02 MPa, constant voltage adjustable precision frequency control is an effective method of energy saving and consumption reducing average energy saving 20% compared with usual pneumatic water supply equipment, in addition, the impact of the variable frequency starting current is small and contributed to the impact of pump is small, little noise when low speed.

The advantages of pneumatic water supply equipment: the cost is relatively low, the control system technology is simple, convenient service, easy maintenance.
