1 Kev tshuaj xyuas qhov ua rau lub foob tsis ua haujlwm thiab cov kev tiv thaiv muaj feem xyuam
Cov laj thawj tseem ceeb ntawm kev foob tsis ua haujlwm yog siab, qhov kub thiab txias, lub sijhawm thiab kev ua haujlwm.
1.1 Siab
Phaj kub exchanger hom muaj tshem tau, kaw, xws li phaj tshem tawm cov cua sov exchanger nyob rau hauv lub rated ua hauj lwm siab, to, ntxiv rau cov khoom nyob rau hauv kev tsim zoo, feem ntau nrog rau lub cev muaj ib tug txawv txav load, uas tsis yooj yim rau tus neeg teb xov tooj. nrhiav qhov tshwm sim. Kev poob siab tshwm sim los ntawm kev nce siab sai sai, lub siab yuav siab dua li qhov qub siab 1 mus rau 3 zaug, yog li ntawd lub installation ntawm lub phaj kub exchanger nyob rau hauv lub sealing gasket tshem tawm, ua rau lub foob tsis ua hauj lwm. Thiab vim tias cov khoom siv ntawm cov khoom siv hluav taws xob hloov hluav taws xob yog tsim los ntawm daim ntawv ib zaug, lub thickness ntawm 0.5 ~ 0.8mm, sealing lub rigidity, bearing kuj tsis zoo, thiab muaj Thaum tshav kub kub exchanger phaj periphery ntev dua, kev cuam tshuam kuj tsis zoo, piv rau lwm yam kub exchangers xws li tubular yuav ntau dua.
Hauv qhov no, kev ceev faj tsim nyog yuav tsum tau ua: nyob ntawm qhov kev ua haujlwm siab, ua kom lub siab tsim ntawm cov khoom siv rau kev siv lub siab 1.5 ~ 2 zaug; siv yuav tsum tau sim kom tsis txhob muaj kev cuam tshuam tshwm sim hauv lub cev; Cov xwm txheej tshwj xeeb los ntsuas kom nce lub thickness ntawm lub phaj.
1.2 Kub
Kev hloov ceev ntawm qhov kub thiab txias kuj ua rau lub foob tsis ua haujlwm. Thaum qhov kub hloov pauv sai heev, qhov nthuav dav coefficient ntawm lub gasket tsis sib haum nrog lub elastic deformation thiab lub preload ntawm lub foob, kom lub preload ntawm lub foob txo qis, uas ua rau lub peev xwm ntawm cov cuab yeej tiv taus tsawg tshaj li qhov ntsuas ua hauj lwm siab. .
Qhov no yuav tsum tau siv cov kev ntsuas hauv qab no los daws: hauv kev ua haujlwm ntawm cov khoom siv yuav tsum qeeb li sai tau kom nce siab thiab kub; nyob rau hauv lub clamping bolt tsim los compress lub preload caij nplooj ntoos hlav los them rau cov kev hloov nyob rau hauv preload quab yuam.
1.3 Sijhawm
Phaj kub exchanger siv lub sij hawm teeb meem, nrog rau kev loj hlob ntawm kev siv lub sij hawm, lub sealing gasket cov ntaub ntawv kuj yuav aging. Ua rau kev siv sealing nyhuv, cuam tshuam cov nyhuv sealing ntawm lub phaj kub exchanger.
Hauv qhov no, raws li cov yam ntxwv ntawm cov khoom siv, xaiv cov khoom tsim nyog sealing washer, thiab raws li kev siv cov xwm txheej sib txawv, kev siv cov sealing sib txawv.
1.4 Cov xwm txheej ua haujlwm
Cov xwm txheej sib txawv ntawm cov txheej txheem nruab nrab tuaj yeem ua rau lub foob tsis ua haujlwm. Xws li qhov kub ntawm lub oversaturated chav rau ib lub sij hawm luv luv yuav ua rau lub foob tsis ua hauj lwm. Thiab tib qhov kub thiab txias saturated chav tuaj yeem tsim cov yeeb yaj kiab dej ntawm qhov chaw ntawm lub gasket, lub gasket tuaj yeem ua lub luag haujlwm tiv thaiv.
Xaiv qhov txheej txheem nruab nrab rau kev ua haujlwm zoo kuj yog ib txoj hauv kev los xyuas kom meej tias cov phaj kub hloov pauv tau tiv thaiv tsis ua haujlwm.
Duab
2 Plug thiab fouling tsis ua hauj lwm yog vim li cas tsom xam thiab coj los tiv thaiv kev ntsuas
2.1 Plug
Phaj hluav taws xob sib txawv ntawm qhov sib txawv me me, txog 2.5 ~ 6mm, txoj kab uas hla ntau dua 1.5 ~ 3mm cov khoom thiab cov khib nyiab yooj yim los thaiv cov channel, kom lub siab poob hauv cov cuab yeej hloov pauv ntau, kev ncig yog txo, qhov kub hloov pauv tau zoo. txo qis, yooj yim ua rau cov khoom siv tsis ua haujlwm. Kev tiv thaiv kev tiv thaiv tuaj yeem teeb tsa hauv cov lim dej tawm hauv xov xwm lossis cov twj tso kua mis, kev tu tsis tu ncua lossis ua haujlwm.
2.2 Scaling
Phaj kub exchanger tom qab siv, vim lub tshav kub hloov los yog txias ntawm qhov nruab nrab, ua rau scaling, scaling yuav ua rau lub phaj kub exchanger tshav kub hloov coefficient yog txo, thiab nyob rau hauv mob hnyav kuj yuav thaiv cov phaj channel. Phaj tshav kub exchanger tsim nrog ib tug loj tus naj npawb ntawm cov kev pab cuam tiv tauj, tsim los txhawb lub ndlwg ntawm xov xwm siab txhawb lub luag hauj lwm, cov kev mob tshwm sim ntawm uas yog ua kom cov kua dej tsim nyob rau hauv lub zos stagnant ntws thiab tsim ntawm fouling, nrog rau lub sij hawm thiab ntawm qhov tsim nyog. qhov kub thiab txias, dej txias calcium thiab magnesium ions nag lossis daus, thiab nce, tsim ntawm honeycomb scaling.
Clogging thiab scaling nyob rau hauv qhov ua rau txawv, tab sis qhov cuam tshuam yog tib yam. Kev tiv thaiv kev tiv thaiv yog: phaj kub exchanger yuav tsum tsis txhob siv cov khoom qias neeg los yog yooj yim rau scale; Tsis txhob siv cov dej tsis muaj dej ua kom txias, thiab qhov kub thiab txias yuav tsum yog qhov yuav tsum tau ua, kom tsis txhob muaj calcium thiab magnesium ions nag lossis daus ntawm thaj chaw kub ntxhov. Tsis tas li ntawd, thaum lub kaw lus tshiab tau muab tso rau hauv kev ua haujlwm, cov khoom siv hluav taws xob yuav tsum tau muab cais tawm ntawm qhov system rau lub sijhawm rau kev ncig, thiab tom qab ntawd muab cov khoom siv hluav taws xob tso rau hauv qhov system siv.
3 Kev soj ntsuam ntawm qhov ua rau corrosion tsis ua hauj lwm thiab kev tiv thaiv kev ntsuas
Phaj kub exchanger corrosion tsis ua hauj lwm hom pitting, crevice corrosion, kev nyuaj siab corrosion cracking, uniform corrosion thiab lwm yam corrosion tsis ua hauj lwm, corrosion yog ib tug complex tshuaj phenomenon, xws li xeb nyob rau saum npoo ntawm lub phaj los yog tsub zuj zuj ntawm scale pitting; nyob rau hauv lub sealing ntawm lub gasket zawj hauv qab los yog lub phaj kaw los tsim crevice corrosion; tag nrho los yog feem ntau ntawm cov hlau nto nyob rau hauv kev sib cuag nrog nruab nrab yog corroded los ntawm corrosion uniform corrosion thiab thiaj li nyob.
Hauv qhov no, cov kev tiv thaiv zoo hauv qab no yuav tsum tau ua: kev xaiv kom raug ntawm cov khoom siv phaj; kev tu cov av tsis tu ncua los rhuav tshem cov xwm txheej thiab kev txhim kho corrosion; kev xaiv ntawm cov tsis muaj chlorine-muaj cov ntsiab lus ntawm cov binder.
4 Tsim, tsim khoom thiab teeb tsa cov laj thawj rau kev txheeb xyuas thiab ntsuas
Vim yog cov yam ntxwv ntawm cov phaj kub exchanger high efficiency thiab lub zog txuag, dav siv nyob rau hauv ntau lub teb, kev soj ntsuam nrog ntau yam kev tshaj tawm, nyob rau hauv kev siv cov txheej txheem ntau lawm, txawm tias ntau yam kev mob yog txawv thiab ntau haiv neeg. Kev xaiv ntawm gaskets yog qhov tseem ceeb, yog tias qhov kev xaiv tsis tsim nyog, cov khoom siv tsis ua raws li lub cev ntawm cov txheej txheem kev tshaj tawm, elasticity tsis zoo, hauv kev siv, muaj de-padding, elongation, deformation, laus, tawg thiab yog li ntawd.
Phaj nyob rau hauv cov txheej txheem tsim, stamping nyob rau hauv lub residual kev nyuaj siab, siv nyob rau hauv corrosive ib puag ncig, yuav tsim kev nyuaj siab corrosion, ncaj qha kev puas tsuaj rau lub phaj.
Qhov saum npoo ntawm lub phaj tsis tiaj tus, cov khoom siv hauv kev teeb tsa thiab siv, kev saib xyuas, nws tsis yooj yim rau nruab rau hauv nruab nrab, ua rau lub zog compression tsis sib xws, cuam tshuam rau lub foob, ua rau kom tawg.
Nyob rau hauv no hais txog, nyob rau hauv lub installation yuav tsum tau sim rau nruab qhov chaw, thiaj li hais tias lub compression quab yuam yog uniform, thiaj li yuav tswj lub compression nyob rau hauv kev siv, tsis muaj to.
5 Kev xaus
Rau cov phaj kub exchanger tsis ua hauj lwm ntawm cov laj thawj rau kev tsom xam, thiab muab tso rau hauv kev tiv thaiv kev ntsuas, nyob rau hauv tus txheej txheem ntawm kev siv, yuav tsum tau siv rau ntau yam ntawm cov phaj kub exchanger siv los tsim kom tsim nyog txij nkawm thiab kev tiv thaiv kev ntsuas, thiaj li hais tias nws plays nws lub luag haujlwm.
