Technical Field

The invention relates to the technical field of water supply systems, in particular to a modularized intelligent non-negative pressure water supply system.

Background

Water supply systems take water from a variety of locations that are suitably treated, including ground water, surface water (lakes and rivers), and desalinated seawater. The water source treatment step generally comprises: decontamination, chlorination, and sometimes including the addition of a fluorinating agent. The treated water is collected into a reservoir by gravity or by pumping water through a water pump and is supplied through a water tower or through a ground facility. After the water is used, the wastewater is typically discharged into a sewer system and treated in a sewage treatment plant before being discharged into rivers, lakes, oceans, or reused for landscape, irrigation or industrial water.

Water is a life source and a necessary substance for people to live and live, and urban water supply becomes a significant problem with the continuous development of urbanization. The current supply method is mainly to take water from reservoirs and rivers, firstly carry out procedures such as filtration and disinfection, then draw the water to the vicinity of a water supply area through a water pump, and finally supply the water to users under pressure through some pressurized water pumps. This approach generally satisfies normal water supply, and when insufficient pressure is encountered, a single stage of pressurized water pump is typically added to the last pressurized water pump or a more powerful pressurized water pump is replaced. After the design, the pressure of the water supply is often over normal pressure, and energy consumption is easily wasted. And when the pressure of the water supply pump group at the user pipeline is overlarge, the front end water supply pipeline is easy to form negative pressure, so that the supply of a water source is short.

The non-negative pressure water supply equipment is ideal energy-saving water supply equipment, can be directly connected with a tap water pipe network, does not produce any side effect on the tap water pipe network, directly folds and supplies water on the basis of the pressure of a municipal pipe network, saves energy, and also has the advantages of full sealing, no pollution, small occupied area, quick installation, reliable operation, convenient maintenance and the like.

The non-negative pressure water supply equipment takes a municipal pipe network as a water source, fully utilizes the original pressure of the municipal pipe network, forms a closed continuous relay pressurization water supply mode, has good energy-saving effect, does not have secondary pollution of water quality, and is the development and extension of variable-frequency constant-pressure water supply equipment. In the long-time operation in-process of water supply line, some troubles can appear, for example pipeline pressure is too big takes place to burst, and the pipeline appears the gap and leaks scheduling problem, not only causes the damage of equipment, the destruction of environment around, makes the water consumer can not normally use water moreover, causes the loss. Meanwhile, workers in the water supply system cannot process in time, which results in great economic loss.

Therefore, a modularized intelligent non-negative pressure water supply system is provided to solve the problems.
