Non-negative-pressure pipe network pressure-superposed flow stabilization and pressure dividing water supply device

Abstract

The invention discloses a non-negative-pressure pipe network pressure-superposed flow stabilization and pressure dividing water supply device. The non-negative-pressure pipe network pressure-superposed flow stabilization and pressure dividing water supply device is mainly composed of a flow stabilization compensator, a non-negative-pressure controller, a water shortage signal transmitter, first water pumps, a second water pump, third water pumps, a first flow detecting device, a second flow detecting device, a first air pressure water tank, a second air pressure water tank and a control cabinet. The water shortage signal transmitter is used for protecting the first water pumps and the third water pumps, and one to four first water pumps and third water pumps are arranged in parallel; and one second water pump is selected in cooperation with the first water pumps and the third water pumps, the flow of the second water pump is 1 / 4 to 1 / 3 of the flow of the third water pumps, and the lift of the second water pump is 85% to 100% of a difference of the lift of the first water pumps and the lift of the third water pumps. The non-negative-pressure pipe network pressure-superposed flow stabilization and pressure dividing water supply device has the beneficial effects that sectional and pressure dividing water supply can be carried out on high-rise buildings; and the non-negative-pressure pipe network pressure-superposed flow stabilization and pressure dividing water supply device is small in occupied land, high in water supply efficiency, good in energy saving, sanitary in water quality, free of pollution, long in service life and complete in protection function, and saving the investment.

Description

technical field [0001] The invention relates to the technical field of secondary water supply, in particular to a non-negative pressure pipe network superimposed pressure stabilized flow and divided pressure water supply equipment. Background technique [0002] At present, the water supply zones of high-rise buildings are usually divided into high zone, middle zone and low zone according to the water supply height, and the low zone is often directly supplied with water by the tap water pipe network, while the middle zone and the high zone use secondary pressurized water supply, which is a common practice It is to set up a set of independent secondary water supply equipment for water supply in the middle area and high area, and each area is not related to each other. Although this can solve the problem of secondary water supply, the water supply of the two sets of equipment occupies a relatively large area, and the investment is high and small. Flow water supply does not save...

Problems solved by technology

[0002] At present, the water supply zones of high-rise buildings are usually divided into high zone, middle zone and low zone according to the water supply height, and the low zone is often directly supplied with water by the tap water pipe network, while the middle zone and high zone use secondary pressurized water supply, which is a common practice It is to set up a set of independent secondary water supply equipment for water supply in the middle area and high area, and each area is not related to each other. Although the problem of secondary water supply can be solved in this way, the water supply of the two sets of equipment occupies a relatively large area, and the investment is high and small. Flow water supply does not save energy, especially in high-lift areas where high-lift, high-power water pumps have low efficiency and high energy consumption under low flow conditions.
