Distributed non-negative pressure electricity-saving water supply regulating and controlling system and method for residential quarter

Abstract

The invention discloses a distributed non-negative pressure electricity-saving water supply regulating and controlling system and method for a residential quarter. The distributed non-negative pressure electricity-saving water supply regulating and controlling system comprises a main water inlet pipe, a main pipe source end flow rate testing device, a sixth pressure sensor, a micro-processor control device, a plurality of pressurizing water supply branches and a plurality of fire-fighting pressure pumps, wherein the main water inlet pipe is communicated with the pressurizing water supply branches, and the main pipe source end flow rate testing device and the sixth pressure sensor are arranged at the source end of the main water inlet pipe; the sixth pressure sensor, fifth pressure sensors of the pressurizing water supply branches and the fire-fighting pressure pump of the water supply region are connected with the micro-processor control device. The flow rate regulating method is capable of alleviating the water supply contradiction between different regions of of a trunk type distribution pump station and good for increasing the pipeline pressure at the pipeline ends and lowering the water use energy consumption for users.

Description

technical field [0001] The invention relates to a water supply control system for residential quarters, in particular to a distributed non-negative pressure power-saving water supply control system and method for residential quarters. Background technique [0002] With the advancement of urbanization, the scale of residential quarters is becoming larger and larger, and the areas and districts are connected. The main water pipes are getting longer and longer, and the branches are increasing. The demand for water supply in the districts and districts is overloaded. As we all know, the pipe pressure of the water supply pipe is limited, that is, after the diameter and section of the water supply pipe are determined, the flow rate of the pipe is almost certain; the diameter of the existing water supply pipe is limited by many factors such as historical conditions, environment, and economic conditions. It is not easy to change. The contradiction between supply and demand of peak w...

AI Technical Summary

Problems solved by technology

This water supply method without a coordination function will result in high water consumption and peak water supply in short supply, making it difficult for end users to supply water; once an accident occurs, such as when firefighting requires water, due to out-of-control flow, limited water resources will be consumed near the water source ( human intervention), near the end or there will be no water available, available

Another problem is that during the stoppage of the booster pump, the pipelines of each user will inhale unclean gas, pollutants, and even small insects due to the negative pressure of the pipeline.
