Method for keeping constant pressure water supply for urban water supply pipe network

Abstract

The invention discloses a method for keeping constant pressure water supply for an urban water supply pipe network. A digital radio is utilized to achieve long-distance data transmission and adopts aDSP technology for self-adaptive balance, a main digital ratio is arranged in a water system control center in the city, main digital ratios are arranged in all subordinate water plants respectively to be used for mutually transmitting data and are mainly in charge of uploading pressure and flow of a main pipe network and water plant data, a pressure transmitter and an electromagnetic flowmeter acquiring device are added on an inlet and an outlet of the pipe network respectively, a signal is wirelessly transmitted, data is transmitted to a water pump house monitoring center through a DSP, datacommunication is conducted with a PLC system of a water delivering pump house of a large earth surface water plant, a water delivering pump is interlocked with pipe network pressure data, and a waterdelivering frequency converter achieves PID control. To solve the problems of water pressure fluctuation among urban tap water pipe networks and long-distance communication, the novel control methodis provided, pressure is automatically kept balanced, and stable water supply is guaranteed.

Description

technical field

[0001] The invention relates to a water supply method, in particular to a method for maintaining constant-pressure water supply in an urban water supply pipe network. Background technique

[0002] As we all know, in terms of the technical performance of the water supply system, the entire water supply system should meet the needs of users for water quality, water volume and water pressure. In addition, in the entire infrastructure construction process and production operation, it also requires low infrastructure investment and low operating costs. It is easy to operate and manage, and the tower-free water supply equipment can produce safely and give full play to the economic benefits of the entire water supply system. Therefore, it is very important to choose the water supply system correctly. There are many factors that affect the selection of the water supply system, mainly including the planning of towns or communities The local terrain, the user's demand ...
