Qhov laj thawj tiag UPVC tsis haum rau RO Membrane Siab Vessels

Rov qab osmosis (RO) yog siab - cov txheej txheem sib cais siab uas yuam cov dej los ntawm ib nrab -permeable membranes kom tshem tawm cov khoom tawg. Txawm nyob rau hauv kev lag luam me me, RO membranes feem ntau xav tau aKev khiav hauj lwm siab tsawg kawg yog ib ncig ntawm 5 bar (72 psi)kom ua tiav cov txheej txheem permeate ntws. Hauv kev lag luam brackish- daim ntawv thov dej, qhov siab feem ntau ncav cuag10-18 bar, thiab seawater systems yuav ua haujlwm siab li55-70 hli. (1Mpa=10bar ≈ 145psi)

Hauv ibmembrane siab hlab ntsha, no hydraulic load yog nruam, pulsating, thiab unevenly faib. Thaum lub siab - lub twj tso kua mis pib, lub nkoj muaj kev kub ntxhov ceev; Thaum lub sijhawm ua haujlwm, kev vibrations thiab ntws turbulence ntxiv cyclic mechanical stress. Qhov no txhais tau tias cov khoom siv rau RO membrane vaj tse yuav tsum tiv taus:

• Tsis tu ncua lub siab sab hauv
• Rov ua dua kev poob siab
• Ntev -lub sij hawm nkees nkees
• Qhov kub thiab txias -txog nthuav thiab contraction
• Tshuaj raug los ntawm cov tshuaj ntxuav

Yog li, thawj qhov kev xav tau ntawm engineering rau ib qho RO membrane vaj tsev yogsiab compressive thiab tensile lub zog. Cov ntaub ntawv uas tsis tuaj yeem ntseeg tau los tuav cov khoom no ua rau muaj kev pheej hmoo ua haujlwm loj.

Unplasticized PVC (UPVC) yog dav siv nyob rau hauv qis - cov kav dej siab vim nws yog corrosion-resistant, qis- nqi, thiab yooj yim rau nruab. Txawm li cas los xij, UPVC cov khoom siv kho tshuab txwv nws lub peev xwm los tswj cov hlab ntsha siab.

Cov kev txwv tseem ceeb ntawm cov khoom muaj xws li:

• Tensile zogntawm UPVC tsuas yog nyob ib puag ncig45-50 psi, qis dua FRP lossis stainless hlau.
• Nruam siabntawm UPVC cov kav dej txo qis nrog qhov kub thiab txias; saum toj 30 degree, nws lub zog poob qis heev.
• UPVC yognkaws, ua rau nws rhiab heev rau kev cuam tshuam, kev vibration, thiab cyclic siab.

Tseem ceeb heev,UPVC tsis tuaj yeem ua haujlwm ruaj ntseg siab dua 3-4 bar hauv siab- nkoj- hom ntawv thov, nyob ntawm thickness thiab tsim. Txij li thaumRO daim nyias nyias yuav tsum muaj tsawg kawg yog 5 bar raws li qhov tsawg kawg nkaus ua haujlwm siab, UPVC vaj tse ntsib ib qho kev pheej hmoo ntawm:

• Kev tawg
• Sudden kev puas tsuaj rupture
• Cov dej ntws hauv qab siab
• Cov qauv tsis ua hauj lwm tshwm sim los ntawm lub twj tso kua mis cycling

Qhov no mismatch ntawmRO ua haujlwm siabthiabUPVC mechanical txwvyog vim li cas UPVC yuav tsum tsis txhob siv rau RO membrane siab hlab ntsha.

Kev siv cov khoom siv tsis tuaj yeem tiv taus RO kev ua haujlwm siab ua rau muaj ntau yam txaus ntshai:

1) Kev Nyab Xeeb Kev Nyab Xeeb

Lub tsev UPVC tawg tuaj yeem tso siab - dej siab tam sim ntawd. Cov neeg ua haujlwm sawv ze ze yuav ntsib:

• Lacerations los ntawm shattering UPVC fragments
• Siab -kev raug mob hauv dej siab
• Hluav taws xob muaj kev phom sij yog tias cov dej txau rau ntawm cov tswj vaj huam sib luag

UPVC tsis ua hauj lwm feem ntau yognkaws, txhais tau hais tias nws tawg tawg ntau dua li maj mam deforming.

2) Kev puas tsuaj rau RO Membranes

Kev tawg tam sim ntawd tuaj yeem ua rau puas tsuaj:

• Membrane ntsiab
• End caps
• Brine foob
• Interconnectors

Qhov no ua rau permeability poob, ntsev to, los yog ua tiav daim nyias nyias.

3) Ntau lawm Downtime

Thaum lub tsev tsis ua haujlwm, tag nrho RO system yuav tsum raug kaw:

• Unplanned downtime
• Cov nqi kho mob xwm txheej ceev
• Hloov cov khoom siv ntau yam
• Muaj peev xwm dej nyab

4) Kev poob dej thiab cov nqi khiav lag luam

Los yog rupture tshwm sim nyob rau hauv:

• Dej pov tseg
• Pump inefficiency
• Kev siv hluav taws xob ntau ntxiv

Hloov lub UPVC vaj tsev ua tsis tau zoo yog ib txwm kim dua li xaiv cov khoom tsim nyog txij thaum pib.

Xaus:
UPVC tsis tuaj yeem ua tau raws li qhov xav tau ntawm kev ua haujlwm RO, thaumFRPtseem yog tus txheej txheem thoob ntiaj teb rau kev lag luam thiab kev lag luam membrane vaj tsev.

Tau kawg,stainless hlau membrane Housingkuj tseem ceeb hauv qee yam kev siv tshwj xeeb. Rau cov lus pom zoo tshwj xeeb, sab laj nrog koj tus neeg muag khoom raws li koj qhov kev lag luam.

Txhawm rau kom muaj kev nyab xeeb, ua haujlwm tau zoo, thiab ua haujlwm ntev - lub sijhawm ua haujlwm, cov neeg yuav khoom-tshwj xeeb yog OEMs thiab cov koom ua ke cog qoob loo- yuav tsum txheeb xyuas:

1. Kev ntsuas siab

Paub meej tias ob qho tib si:

• Qhov siab tshaj plaws ua haujlwm siab (MOP)
• Kev ntsuas kub siab

Piv txwv li, FRP vaj tsev feem ntau muaj MOP kev ntsuam xyuas los ntawm 300 psi (20 bar) txog 1200 psi (82 bar).

2. Daim ntawv pov thawj & Cov qauv

Tshawb xyuas kev ua raws li cov qauv xws li:

• ASME Sec. X
• ISO 9001 cov txheej txheem tsim khoom
• NSF / ANSI 61 rau cov dej haus
• CE daim ntawv pov thawj rau European lag luam

Xi'an Ink-blue Environmental Protection Technology Co., Ltd.muaj ua tiav ASME, NSF, CE, ISO, thiab lwm yam ntawv pov thawj.

3. Kev sib haum xeeb

Xyuas kom cov vaj tse sib tw:

• Membrane caij ntev (4040, 8040, thiab lwm yam)
• Hom kev sib txuas (sab chaw nres nkoj / kawg chaw nres nkoj)
• O- cov khoom siv nplhaib

4. Kev Pabcuam Chaw Tsim Tshuaj Engineering

Vim tias RO system tsim ncaj qha cuam tshuam rau kev ua tau zoo, xaiv cov neeg muag khoom uas tuaj yeem:

• Muab cov kev ntsuas kev ntsuas siab
• Muab cov duab 3D
• Customize lub kaus mom kawg thiab cov chaw nres nkoj
• Txhawb kev taw qhia kev teeb tsa

Cov tuam txhab uas muag nrog engineering pab pawg xa cov txiaj ntsig zoo dua.

Ib tus neeg siv khoom los ntawm Pakistan tau hu rau Xi'an Ink -blue Environmental Protection Technology Co., Ltd. nrhiav kev yuav1,000 units ntawm 4080 membrane vaj tserau qhov tshiab RO system. Txhawm rau txo cov nqi khoom, tus neeg siv khoom tau hais kom sivUPVCraws li cov khoom siv vaj tse.

Peb pab neeg engineering tam sim ntawd qhia rau cov neeg siv khoom tias UPVC yogtsis haumrau RO membrane siab hlab ntsha vim nws tsis tshua muaj siab kam rau ua. Tus neeg siv khoom, txawm li cas los xij, tseem ruaj khov thiab thov cov ntaub ntawv pov thawj.

Txhawm rau kom pom tseeb, peb cov engineers tau ua thiab sau ahigh -kev ntsuas siabtshwj xeeb rau UPVC vaj tsev. Cov txiaj ntsig tau pom meej meej cov khoom siv cov kev txwv:

• Ntawm4bar ua, UPVC vaj tse twb tshwm simsiab - siab ceeb toom teeb liab.
• Ntawm4.5bar ua, lub tsev muaj kev paubkev puas tsuaj loj, nrog lub plhaub rupturing dheev.

Peb muab cov neeg siv khoom nrogkev ntsuam xyuas siab, tiag test footage, thiab kev sib piv ntawm FRP, stainless hlau, thiab UPVC siab ua haujlwm. Raws li cov ntaub ntawv thiab cov lus piav qhia tshaj lij, tus neeg siv khoom thaum kawg tau lees paub qhov kev pheej hmoo thiab xaivFRP daim nyias nyias, uas muab ob qho tib si txhim khu kev qha thiab tus nqi -sib npaug zoo rau nruab nrab -siab RO systems.

Xi'an Ink-blue Environmental Protection Technology Co., Ltd.tsim, tsim, muag, thiab installation. Peb cov khoom lag luam suav nrog kev kho dej ua kom tiav, RO daim nyias nyias, cov khoom siv membrane, FRP siab hlab ntsha, lim cartridges, thiab cov khoom siv OEM customized.

Peb pab neeg ua haujlwm engineering tuaj yeem tsim cov phiaj xwm kev kho dej raws li koj txoj kev xav tau, lossis tsim cov khoom raws li koj cov duab kos thiab cov qauv.
