Non Negative Pressure Water Supply Improve Water Supply for Residents

Product Name: Non Negative Pressure Water Supply Improve Water Supply for Residents Model NO.: WFY-01 Theory: Axial Flow Pump Performance: Automatic Pump Media: Air Pump Industry: Air Conditioning Pump Application: Submersible Pump, Clarified Water Pump, Sewage Pump, Slurry Pump, Oil Transfer Pump, Chemical Pump Type: Positive-Displacement Pump Start Up: Electric Pump Power: Hydraulic Assembly: Pipeline Pump Structure: Multistage Pump Material: Stainless Steel Driving Type: Motor Max.Capacity: >400 L/min Max.Head: 110m-150m Trademark: SDCHENUXAN Transport Package: Wooden Case Specification: 1 Origin: China Product Description NonnegativepressurewatersupplyThebidirectional compensatorstartstowork,the high-pressure water pump outler to the higeh-pressure chamber end to water, when the liquid nitrogen increased gradually ,with pressure being squeezed back to the energy storage device,thus completing the process of the low peak to the tank water,whenthe peak of water drop or municipal pipe network pressure,the release of energy storage device extrusion high pressure chamber water,together with the constant pressure cavity to the user with municipal water replenishment,thus completing the process of peak water to users.3energystorageNitrogenenergystoragebuiltinpreloadingarenotsolubleinwater, whenthepeakofwater,energyreleaseI highpressureI chamberwaterpressuretotheextrusioncavitynetwork, makefulluseoftheprincipleofthelawofconservationofenergy,toachievethepeakwaterusers, toensurethewaterinthepotto thegreatestdegreeI of compensationI tothe user in the network,suppressionofnegativepressuregenerated, guaranteeIwithoutaffecting themunicipal pipenetwork.3controlpointseditcontroltechnologyNonnegativepressurewatersupplysystemissettoaconstant pressurevalue, ifthepipepressureishigher than theset pressurevalue, thepressure transmitter pipelinepressure feedbacktothefrequencyconversioncontrolcabinet,tapwaterbydirectsupplypipelinedirectlytotheuserontheuserwatersupplypipenetwork.

Through the vacuumcompensation system and the I fully enclosed struc ture, the equi pment real izes the direct connection with the water pipe ne twork, and overcomes the adverse influence on the pipe ne twork. The device through the pipe pressure gauge, vacuum and water level signal, and the steady flow compensator in a vacuum suppressor compensator in the test device I for collecting real-time feedback through the microcomputer control device, special vacuum suppressor and the steady f low compensator, suppression Of negative pressure generated, ensure I that the equipment does not affect the city network.The system is directly connected with the municipal water supply network , and the water supplu will not cause negative pressure to the municipal water supply network. When the municipal pipe network pressure drops even without water , the pump unit can still work ,and out of the water until the time variation of the steady flow compensator in the negative (watchdog) or by a simple low level control mode when the water pressure decreases to elctrically contact the set lower limit pressure after the automatic shutdown, automatic starting after the runoff . When the power failure occurs, the water pump unit stops working, and the tap water can enter the use's pipe network through a through pipe , When calling ,the unit will automatically turn on and resume normal water supply .Automatic pressure compensation techniqueAccording to the system resistance characteristic , when the flow rate is bigger, In order to meet the system in maximum water when there is enough head to overcome the resistance of the system general manufacturers in setting the system pressure only by the maximum flow tate of the pressure required to set up ,when the small flow fo water pressure caused by excessive waste of energy. According to the set pressure automatic regulating system with the change of water , running at low pressure value in the small flow of water ,along with the incresse of water consumption , the system according to the hydraulic characteristics , the use of the system pressure increases gradually .Thus , the electric energy is saved to the maximum extent.4 scope of application edit1 , the user original pressurization system energy conservation ,consumption reduction transformation .2, various types of reclaimed water , sewage and wastewater treatment plants;3, all types of waterworks ,feed pressure pump station;Constant pressure oil system4,oil pipelines, oil depots , oil pump station ,oil etc ;5,non negative pressure water supply equipment is also applicable to all kinds of industrial and mining enterprises production water ( such as circulating cooling water ,industrial boiler water, industrial boiler water supply system and so on ,need constant pressure production water );6, hige-rese buildings, residential areas ,enterprises and institutions ,such as life ,fire water supply system ,HVAC, centeal air conditioning cycle and separation5, advantages and disadvantages ,editng advantages1., make full usd of the city pipe network pressure ,greatly save energy.2 . avoid the two plllution of water .3. save floor space.4. save investment .5. convenient maintenance6. save operating costs7. keep constant pressure8. blackouts,continuous water.Shortcoming Nonnegativepressurewatersupplyhascertainshortcomings,becauseno nonnegativepressurewatertankcanstore water, buttheamountisverysmall,whenthemunicipalpipenetworkwater, userswillsoonwithoutwateruse, sointhe choiceof non negative pressure water supply, canalsoconsider nonnegativepressurewatersupplyequipmentbox, stainlesssteel water tank assemblyincreasebased onnonnegat1vepressurewatersupplytheunitisavailable fromafewtothousands ofthe reserves, to meetthedifferentneedsof customers.6otherwatersupplysevenedit1. pollution:tapwatermustfirstintothepoolor watertank, poor sealingperformance,arealwayscontaminatedbydebris, dirt andevenanimaI carcasses, willproducescaleandbacteria,seriouslyaffectsIthehealthofusers.2.,highinvestment:theneedtobuildpoolorwatertank,highconstructioncosts.3., large land: the need to build a pool or water tank, equi pmentcoversaIargespace,willoccupyalargenumberofcommercialland,reducerevenue. 4.,highenergyconsumption:becausethetapwatermustbeputIintothe pool orwatertank, andthenpressurized, resulting inmunicipal pipenetwork pressureutilizationis zero,seriouslywastingenergy.5.,waste serious: mostof thepooluseof civilstructure, oftenoccurseepage,running,leakageandotherphenomena,dueIto seriouspollution, but also needtousealargenumber of regular waterI forcleaning, waste serious.6.installation:tobuildcomplexwatertankorpool,complexIinstallation,longconstructionperiod.7.,highmaintenancecosts: regularcleaning,disinfectionand othermaintenancework, latecleaningand maintenancecosts.
