High-rise pressure-superposed water supply equipment

Abstract

High-rise pressure-superposed water supply equipment is provided with an underground pressurizing device, a plurality of medium pressurizing devices and a roof reserve tank, wherein the underground pressurizing device is connected with the medium pressurizing devices through a pipeline; the medium pressurizing devices are connected with the roof reserve tank through a pipeline, and can be arranged for step-by-step pressurizing according to the height of a building; the underground pressurizing device is provided with a connector connected with a water source (tap water); the roof reserve tank is provided with a water supply connector. The pressure configuration of the underground booster pump group is only required to meet the requirement of the height of the medium pressurizing devices, and is pressurized to the roof reserve tank step by step through the medium pressurizing devices, so that the loading capacity of the whole water supply connecting pipeline is reduced effectively, and workers' labor intensity, equipment investment and occupied area are reduced.

Description

technical field [0001] The invention relates to a superimposed pressure water supply equipment, in particular to a super high-rise building domestic water supply superimposed pressurized equipment. Background technique [0002] The water supply of existing super high-rise buildings is generally to set up a booster pump room at the bottom of the building, and set up a water storage tank at the top of the building. The underground booster pump room lifts water to the roof water storage tank through a pump, and then the The roof water tank supplies water to users, so the pressure of the pump is very high. At the same time, the thickness of the pipe connecting the roof water tank must be increased in order to increase the pressure bearing capacity, which leads to high installation strength and high material cost. If the height of the building is super high, there are also water storage tanks and intermediate booster pumps arranged in the middle of the building, and water is draw...

Problems solved by technology

[0002] The water supply of existing super high-rise buildings is generally to set up a booster pump room at the bottom of the building, and set up a water storage tank at the top of the building. The underground booster pump room lifts water to the roof water storage tank through a pump, and then the The roof water tank supplies water to the user, so the pressure of the pump is very high. At the same time, the pipe connecting the roof water tank must increase in thickness in order to increase the pressure bearing capacity, which leads to high installation strength and high material cost.

If the height of the building is super high, there is also a water storage tank and an intermediate booster pump in the middle of the building, and the intermediate booster pump is used to draw water to the roof water tank, but this increases the cost of equipment investment and a large area.
