Optimization Design Of Electrical Control System For Residential Block Secondary Water Supply

The background of this essay is the secondary water supply management within the cityof Zhuhai City, combining the research status quo of domestic secondary water supply, toexpatiate the style of various stages of development and technology on the second watersupply. Based on the latest available technology method to put forward the design after theoptimizing of the secondary water supply, achieving the purposes: conserve energy, reduceequipment wear and tear, and improve the quality of urban water supply.Describing several common ways of water supply in the residential district of ZhuhaiCity and analyzing the advantages and disadvantages existing in the various water supplystyles. The article also introduces the principle of frequency conversion constant pressurewater supply, the working of the overlying water supply, to analyze the energy conservationprinciple and summarize their respective advantages and disadvantages. Introducing newtechnology box overlying water and analyzing the working principle, advantages anddisadvantages, to propose two kinds of box-type overlying water supply program, andcompare at the same time. This paper is according the status of the secondary water supplyin Zhuhai City as its background, based on a medium size of the residential area as its originaldata, to compute the capacity of the equipments, design the system plan, optimize thesecondary control system design, and describes the working principle.This paper includes the following aspects:Firstly, introducing the status quo of the existing residential area of Zhuhai Citysecondary water supply and a brief description on the secondary water supply managementmodel in the various cities and the related research direction on the domestic secondarywater supply.Secondly, introducing the structure and system diagram of the frequency conversionconstant pressure water supply. Analyzing the working principle and energy conservationprinciple of the frequency control water supply. Summarizing the advantages of thefrequency conversion constant pressure water supply.Thirdly, introducing the system and working principle of the overlying water supplysystem, the principle of preventing the negative pressure. Summarizing the benefits of theoverlying water supply and the problems in the use of the water supply.Fourthly, the comparative analysis of the advantages and disadvantages of the frequencyconversion constant pressure water supply and overlying water supply, proposing the secondary control box overlying water supply system optimization approach and itsadvantages. Designing two kinds of boxes overlying water supply program, introducing thesystem diagram of the two options, the working principle and analysis and comparison.Fifthly, according the secondary water supply status quo in Zhuhai City as thebackground and based on the scale of a medium-sized residential district as the original data,to compute device capacity, design the system diagram and optimize the secondary controlsystem design.
