1. Cov qauv qauv thiab kev faib tawm: Tsim Logic rau kev yoog raws kev ua haujlwm txawv
Lub pob tawb sab nraud yog cov khoom siv cougelines uas cuam tshuam rau cov pob tawb ntawm kev tshem tawm pob tawb {0} zoo li cov tshuab lim. Nws cov ntsiab lus tseem ceeb suav nrog lub cev lub tog raj kheej, cov pob tawb lim, xaus npog, thiab blowdown chaw nres nkoj. Cov qauv tsim ncaj qha ncaj qha txiav txim siab nws cov xwm txheej uas muaj feem xyuam, thiab nws feem ntau muab faib ua peb hom tseem ceeb:
Ncaj -} los ntawm hom: Cov inlet thiab qhov hluav taws xob tau teem rau hauv kab rov tav ncaj kab, muaj kev sib cav flasing channel nrog lub siab poob feem ntau tsawg dua 0.02mpa. Nws yog qhov haum rau loj {2} eg thiab dn5000 caliber) thiab yog hom uas nyiam tshaj plaws hauv kev lag luam petrochemical thiab kev lag luam fais fab.
Siab - qes pob tawb hom: Cov inlet thiab qhov hluav taws xob yog misaligned nyob rau hauv qhov siab, uas tuaj yeem phim cov kev txwv ntsug ntawm - chaw xa xov. Raws li qhov tsis - Txheem customized hom, nws feem ntau siv nyob rau hauv chav {} kev tsim kho cov chav tsev lossis cov pipeline kev tsim kho qub.
-}} QHIB HOM: Qhov kawg npog tau txuas nrog bolts qhov muag thiab Lifting ceev, tso cai qhib yam tsis muaj tag nrho cov fastenemling. Tu lub tshuab lim ntim tsuas yog siv ob peb feeb, ua rau nws tsim nyog rau kev ua haujlwm cov ntsiab lus thiab kev saib xyuas tsis tu ncua (piv txwv li, zaub mov slurry pom).
Cov tub ntxhais lim lub caij - lub pob tawb "lim" feem ntau yog welded los ntawm stainless hlau xees roj (feem ntau 304 / 316L) thiab hlau ncej. Tus ntxaij suav txog kev tshuaj ntsuam txiav txim siab qhov kev txiav txim siab: 10-30 mesh (pore loj 0.6-2 hli) yog siv los sib txuam xws li vuam slag thiab sediment; 40-100 mesh (0.15-0.4mm) yog tsim nyog rau kev lag luam kev lag luam dav dav; 100-300 mesh (0.05-0.15mm) tuaj yeem ua tau raws li qhov xav tau zoo ntawm cov tshuaj thiab kev lag luam hluav taws xob.
2. Kev Xaiv Tseem Ceeb thiab Cov Khoom Xaiv: Cov Qauv Hauv Paus Rau Kev Ua Haujlwm Kev Ua Haujlwm
Qhov ua tau zoo yoog raws li lub pob tawb txoj kev sib txawv yog nyob ntawm parameter txuam. Cov ntsiab lus tseem ceeb thiab xaiv cov laj thawj yog li nram qab no:
2.1 Cov Tub Ntxhais Kawm Ua Haujlwm Tsis Txaus
Chav Kawm Siab: Cov Qauv Qauv Them PN0.25 {{pn2.5 (chav kawm ntawv siab customized qauv tuaj yeem tiv toj PD42MPA. Lub khauj khaum lub hau kev ntsuas siab yuav tsum yog 1.5 zaug ntawm cov huab cua nrawm yuav tsum yog 1.1 npaug ntawm cov nominal siab.
Qhov ntsuas kub ntau: Qhov kub siab tshaj plaws kuj yog txiav txim siab los ntawm cov khoom siv - carbon hlau shells yog haum rau {10℃rau 450 degree; Stainless hlau plhaub tuaj yeem txuas ntxiv rau {4 4}}} 196 qib (tsawg-kub ua haujlwm); PTFE-lined cov ntaub ntawv tsuas yog txwv tsis pub dhau 150 degree.
Av {{{}}} tuav lub peev xwm: Cov ntim ntawm lub tawb tawb yog 3 {-} preatends lub peev xwm ntxuav thiab txo qis downtime.
2.2 Cov Lus Qhia Xaiv
Kev xaiv cov khoom yuav tsum tau ua kom haum nrog cov yam ntxwv nruab nrab, uas yog qhov tseem ceeb kom tsis txhob muaj cov cuab yeej siv corrosion thiab ua tsis tiav:
Me ntsis corrosive media (dej, huab cua): Nrum hlau lossis cov hlau ua hlau lossis cov hlau nyiam, ntsuas tus nqi thiab kev coj ua, thiab haum rau HVAC thiab kev ntsuas dej hauv nruab siab.
Cov kua qaub tsis muaj zog - puag / khoom noj xov xwm: 304 lossis 316 Stainless hlau yog siv los ntsib corrosion tsis kam thiab kev ua kom huv; Lub tsev tshuaj kev lag luam yuav tsum muaj kev ua raws li GMP.
Cov xov xwm muaj cov xov xwm (concentrated acids, chloride -} muaj cov kev daws teeb meem): 316L Stainless hlau lossis PTFE - Txoj kev lined (cam khwb cia steel plhaub + PTFE hauv ob sab phlu) tau saws; 2205 Duplex Stainless hlau yuav siv tau rau cov khoom siv marine engineering.
High - viscosity / yooj yim-- solids, cov roj hnyav): Cov ris tsho rwb thaiv tsev rwb thaiv tsev yuav tsum tau, thiab cov roj hloov cua sov siv rau cov cua sov los tiv thaiv cov solidification thiab lim thaiv.
3. Raug ntawv thov cov xwm txheej: "thawj kab ntawm kev tiv thaiv" rau kev tiv thaiv cov khoom tseem ceeb
Cov tseem ceeb ntawm cov pob tawb cov lus dag hauv kev tiv thaiv cov khoom siv thev naus laus zis, thiab lawv ua ib qho kev lag luam ua ntej ua ntej kev lag luam hauv ntau yam kev lag luam:
Petrochemical Kev Lag Luam: Nruab rau ntawm cov inlets ntawm cov roj teeb roj hmab roj av thiab reactors los cuam tshuam gravel, catalyst hais, thiab xa cov khoom corrosion corrosion.
Fais Fab System: Siv nyob rau hauv pem hauv ntej theem ntawm theem boiler
Cov Khoom Noj Khoom Haus Thiab Dej Haus: Cuam tshuam cov txiv hmab txiv ntoo seem thiab cov khoom ntim hauv syrup thiab txiv hmab txiv ntoo cov kua txiv ntau lawm kab; Huv 316L Cov Qauv Khoom Siv tuaj yeem hloov kho kom cov tshuab ntxuav tu kom tsis txhob muaj cov khoom paug.
Dej Kho Teb: Ua haujlwm ua ntej - kev tiv thaiv rau RO WICBranes thiab ion sib pauv cov khoom lag luam thiab cov dej sib zog ua kom muaj kev txhim kho kev ua tau zoo.
Piv nrog lwm cov neeg sib zog, pob tawb txoj kev sib zog muaj qhov tseem ceeb ntawm tib lub cal6 {1} {{1} {} ntev - lub sij hawm tu cov nqi.
4. Txhim Kho thiab Kev Ua Haujlwm & Kev Txij Nkawm: Cov Ntsiab Lus Cov Ntsiab Lus thiab Cov Lus Qhia Kev Nyab Xeeb
4.1 Cov Ntsiab Tseem Ceeb Cov Lus Qhia
Kev teeb tsa yuav tsum ua raws li qhov ntsuas nruab nrab ntws; ncaj -}} los ntawm cov hom yuav tsum tau muab khawm tav toj nrog cov lim pob tawb qhib upward; Siab - Cov khoom siv tawb ntau yuav tsum nruj me ntsis sib txawv qhov qhov siab txawv ntawm cov raj xa hluav taws xob thiab qhov hluav taws xob.
Flange kev sib txuas yog nyiam rau txoj kev sib txuas; Taub qab vuam txuas tau raug pom zoo rau cov nqi hluav taws xob loj (DN300 thiab siab dua); Tsis - nws yuav tsum tau muab tshem tawm thaum lub tshuab vuam txhawm rau tiv thaiv kev puas tsuaj los ntawm overheating.
Siab - h siab lossis cov haujlwm ua haujlwm txuas ntxiv yuav tsum tau nruab nrog lub pob ntawm lub pob lossis rooj vag
4.2 Cov ntsiab lus hauv kev ua haujlwm & txij nkawm
Kev Txiav Txim ntawm Tu Sijhawm: Kev tu yog yuav tsum tau ua thaum inlet - o} o} o rov ua rau lub siab 0.1-0.15mpa; Ib nrab tuaj yeem tau nqus ua ntej dhau los hauv qab BlooDown Plug, tom qab ntawd qhov kawg npog qhib kom tshem tawm cov lim lim.
Cov kab hauv qab rau kev ua haujlwm zoo: Lub kaw lus yuav tsum muaj kev nyab xeeb tag nrho ua ntej qhib qhov kawg npog los tiv thaiv kev tshaj tawm xov xwm ntawm kev txau thiab ua rau raug mob; Zam kev nyuaj khoom los tsoo lub lim screen thaum tu; Yog tias mesh deformation lossis puas yog pom, hloov nws tam sim ntawd.
Ntev -} Lub Tswv Yim Kev Txij Nkawm: Rau cov lim pob tawb tu, siab {{}} cov phom dej dej ntws los yog cov pa hluav taws xob tau zoo dua; nruab nrab cov kuab tshuaj tuaj yeem siv rau cov roj -} Raws impurities; Cov gaskets tshiab (fluororubber lossis cov khoom siv fluororubber lossis hloov kho cov duab graphite
5. Coj kom tsis txhob xaiv qhov Pitfalls: 3 qhov tseem ceeb txiav txim siab
Precision Matching: Xaiv raws li lub tshuab hlab me me uas cov khoom siv hauv dej ntws tawm ntawm cov twj tso kua mis, thiab 100-150 ntawm cov khoom siv twj tso kua mis, thiab 100 teev
Txaus kev xam: Lub Strainer Caliber yuav tsum tsis txhob me dua cov inlet ntsuas hluav taws xob, thiab 20%}} sij hawm overload.
Chaw Adjustation: Ceev {{-}}}}} qhib hom yog qhov xav tau qhov chaw qhib kev ua haujlwm zoo kom tsis txhob qhib qhov chaw zoo nkauj- xov} xov} xov} hom kawg npog; Los nag cov ntaub thaiv yuav tsum teeb tsa rau sab nraum zoov teeb tsa los tiv thaiv cov plhaub corrosion.
Ua ib qho cuab yeej nrog cov qauv yooj yim tab sis cov qauv kev xaiv ua haujlwm zoo, thiab kev xaiv kom raug "
