The constant pressure and frequency conversion water supply equipment is a sophisticated pressurized water supply equipment which is composed of the latest performance frequency conversion control cabinet and 2 or more pumps. It can automatically adjust to meet the user's constant voltage variable frequency variable water supply requirements. The pressure of the water supply network is kept constant, and the whole water supply system always maintains the best state of high efficiency and energy saving. There are two ways of water supply: frequency conversion water supply and pressure water supply. Frequency conversion water supply is an ideal way to automatically adjust the speed of a pump or the operation of multiple pumps, and keep the pressure of the water supply pipe network constant. The operation is simple.
Scope of application
Residential water for residents: such as high-rise buildings, residential quarters, villas, etc.
Public places: such as hospitals, schools, gymnasiums, golf courses, airports
Commercial buildings: such as hotels, office buildings, department stores, large sauna, etc.
Irrigation: a park, a playground, a orchard, a farm, etc
Manufacturing: such as manufacturing, washing equipment, food industry, factory
Advantages of equipment
1, to solve the problem of low water pressure
- the whole building house by the constant pressure water supply if the water supply to keep constant pressure.
2. Avoid the water pollution caused by the use of the roof water tank
- replacing the traditional water supply mode of the roof water tank, eliminating the source of water pollution.
3, reduce the cost of building and increase the space area
- canceling the traditional roof water tank to reduce the force of the building, the structure is simple, the cost is reduced.
4. Save electric energy and reduce the area of land
- power saving more than 30% of the general water supply equipment, the equipment has a small area, simple installation, shorten the construction period.
