Energy-saving type non-negative-pressure pipe network pressure-superposed flow-stabilizing and pressure-dividing water supply device

Abstract

The invention provides an energy-saving type non-negative-pressure pipe network pressure-superposed flow-stabilizing and pressure-dividing water supply device. The device comprises a detection and pressure-stabilizing assembly, a pressurizing assembly, an intelligent control assembly and a power supply for supplying power to each electrical element. According to the energy-saving type non-negative-pressure pipe network pressure-superposed flow-stabilizing and pressure-dividing water supply device, pressurizing is superposed on the basis of original pressure of a pipe network, so that the pressure of the municipal pipe network is sufficiently utilized, continuous and stable water supply in a peak period is guaranteed, and uninterrupted water supply is really realized; even if power is off,water utilization of users in a low region also can be guaranteed, the operation is stable and the reliability is high; when the water supply device is used for normally supplying water, water supplyrequirements of the users with different heights can be met through a variable-frequency pressurizing water pump set I and a variable-frequency pressurizing water pump set II; the energy-saving type non-negative-pressure pipe network pressure-superposed flow-stabilizing and pressure-dividing water supply device occupies a small area, saves the investment and has high water supply efficiency; meanwhile, in a low peak period, standby water storage tanks can be used for supplying the water; meanwhile, all the standby water storage tanks are communicated with one another, so that normal water supply in each region is guaranteed when a water pump is overhauled; and the energy-saving type non-negative-pressure pipe network pressure-superposed flow-stabilizing and pressure-dividing water supply device has the advantages of energy saving and environment protection, sanitary water quality, no pollution and long service life.

Description

technical field [0001] The invention belongs to the technical field of water supply equipment, and in particular relates to an energy-saving non-negative pressure pipe network superimposed pressure stabilized flow and divided pressure water supply equipment. Background technique [0002] With the development and progress of social economy and technology, the water quality standard of municipal water supply system is gradually improved, and the water supply capacity is continuously enhanced. In order to meet the requirements of social development, automatic water supply equipment must develop in a certain direction. This direction is to develop more efficient and energy-saving, It is a pipe network superimposed water supply equipment that prevents pollution, is silent, is easy to operate, and operates reliably. [0003] Pipe network superimposed pressure (no negative pressure) water supply equipment is mainly composed of four major parts: municipal pipe network protection sys...

AI Technical Summary

Problems solved by technology

[0005] When the existing pipe network superimposed pressure (no negative pressure) water supply equipment is used, there will be certain problems more or less, for example: it cannot solve the problem of interruption of water supply caused by fluctuations in the pressure and flow of municipal water sources, and The overall equipment occupies a large area, the pipeline is complicated, and the installation is troublesome. At the same time, the cleaning process of the existing water supply equipment steady flow tank is cumbersome, the cleaning is not thorough, it is easy to cause secondary pollution to the water source, and there is no backup water supply function. Therefore, it is urgently needed A water supply equipment with energy saving, environmental protection, hygienic water quality and stable operation to meet the requirements of use
