Negative pressure-free water supply pump station

Abstract

The invention discloses a negative pressure-free water supply pump station which comprises a water storage tank, an electric control cabinet and a booster pump set, wherein a filter, a first pressure transmitter, an electromagnetic flow meter, a residual chlorine detecting instrument, an influent flow regulator and a first electric valve are sequentially arranged between a tap water pipeline network and a water inlet of the water storage tank; an ultraviolet sterilizer is arranged between the booster pump set and a water outlet of the water storage tank; and a pressure regulator and a second pressure transmitter are sequentially arranged between the booster pump set and a user pipe network. The negative pressure-free water supply pump station also comprises a by-pass pipe, wherein one end of the by-pass pipe is connected with the influent flow regulator, the other end of the by-pass pipe is connected with the pressure regulator, and the by-pass pipe is provided with a second electric valve. The negative pressure-free water supply pump station also comprises a secondary by-pass pipe, wherein one end of the secondary by-pass pipe is connected with the ultraviolet sterilizer, and the other end of the secondary by-pass pipe is connected with the pressure regulator. The negative pressure-free water supply pump station provided by the invention has the functions of energy saving, water saving, environmental friendliness, reliable water supply pressure and water quality, no negative pressure generated by a municipal water supply network, and the like.

Description

technical field [0001] The invention relates to tap water supply equipment, in particular to a non-negative pressure water supply pumping station. Background technique [0002] The main function of the non-negative pressure water supply equipment is to increase the pressure of the water pipe network, which is mainly used in residential areas, schools, rural areas, industrial and mining areas with low water supply pressure. At present, there are mainly two types of non-negative pressure water supply equipment in my country, one is tank-type non-negative pressure water supply equipment, and the other is box-type non-negative pressure water supply equipment. The basic structure of the two types of equipment is similar, mainly including water storage tanks or storage tanks, water pumps, control cabinets, valves, pipelines, various instruments, etc. The water storage tank (box) is used to store water to adjust the water supply flow, the water pump is used to pressurize, the inst...

AI Technical Summary

Problems solved by technology

[0003] The two types of equipment have their own advantages and disadvantages. The advantages of tank-type non-negative pressure water supply equipment are that they can make full use of the residual pressure of the municipal water supply network, save power consumption, and occupy less land. Users with low pressure and large water demand; the advantage of the box-type non-negative pressure water supply equipment is that the box has a large volume and a large adjustment function. The disadvantage is that the water storage tank adopts a normal pressure design and cannot use the residual pressure in the municipal water supply network High power consumption and many materials are used, and the water stays in the box for a long time, which is easy to form dead ends and bacteria, which is not good for human health
