I高楼供水系统设计摘要伴随当代社会经济的持续发展，城市建设规模不断扩张，因为土地资源持续缩减的现状，高层楼宇的建设具备关键的价值。伴随民众对供水质量以及相关系统可靠性的标准持续提升，之前的供水系统逐渐无法满足高层楼宇的供水需要。在世界各国提倡节省资源，降低损耗，发展低碳经济的宏观环境中，使用领先的自动控制技术、检测和传感器技术和通信技术，设计出性能齐全、损耗较少、可以适应多个行业的恒压供水系统就变成重中之重。利用分析与对比，本文设计出高楼层基于PLC的变频恒压供水系统。此系统的主要特点是节省资源、确保运作稳定、便于后期维护，主要包含可编程控制器、变频器、水泵电机组等众多部分，完成高楼供水顺利的自动化体系。主要是通过多种反馈压力值，自主调节水泵输出量不只可以节约之前使用调节阀门开关而损耗在内部阻力以及截流掉的能量，此外还可以减少因设备多次开启和暂停对整个系统的负面影响，弱化对整个电压的负面影响，防止设备猛然加速导致系统的喘振问题，可以全面解决现实问题。关键词：高层楼宇恒压供水变频调速PLCIIAbstractHigh-risebuildingconstructionhasaveryimportantsignificance,Alongwiththerapiddevelopmentofmodernsociety、economyUrbanconstructionscaleandFacingtheincreasinglyshortageoflandresources。Thetraditionalwatersupplysystemhasbeendifficulttosatisfyhigh-risebuildingwatersupplydemand.Alongwiththepeoplecontinuouslyimproveofwaterqualityandwatersupplysystemreliabilityrequirement.Throngssuingadvancedautomaticcontroltechnologydetection，sensortechnology，communicationtechnology，Designhighperformance，lowenergyconsumption，adaptingdifferentfieldsofconstantpressurewatersupplysystembecomesanecessarytrend，Underthebackgroundofinternationalsocialadvocacysavingenergyconsumption，andlowcarboneconomydevelopment。Humansdesignedasetofhigh-risebuildingsbasedonPLC，frequencyconstantpressurewatersupplysystem.Throughtheresearchandcomparethispaper.，Thiskindofsystemissafesystemwithenergysavingenvironmentalprotection.SystemsecurityandstabilityusingveryconvenientabouttheautomaticwatersystemandiscomposedbyconvenientusageandmaintenanceofwatersupplycontrolsystemwhichconsistsmainlyofPLC，frequencyconverter，pumpelectricalunits，pressuresensor，realizetheautomationofbuildingwatersupply.，Thesystemcanself-adjustoutputwaterpumpthroughthedifferentfeedbackpressurevalue，andalsocansavethetraditionaladoptionofregulatingvalvesopendegreeandconsumptioninthepipelineresistanceandinterceptingthelossofenergy，andsavebecauseofconstantspeedpumpoffrequentstart-stopnetsystemoftheimpactenergyandforgridvoltagefluctuationcausedbytheinfluenceofthemotor，avoidsuddenaccelerationcausedpumpsystemsurge，caneliminatewaterhammerphenomenonKeyword：High-riseBuilding，ConstantPressureWaterSupply，VariablevelocityVariablefrequency，PLCIII目录摘要................................................................................................................IAbstract.........................................................................................................II前言...............................................................................................................11高楼供水系统概述...................................................................................11.1本课题产生的背景和意义.............................................................11.2变频恒压供水的现况......................................................................11.2.1国内外变频供水系统现状....................................................11.2.2变频供水系统...
