Plhaub thiab raj kub exchangersyog cov neeg ua haujlwm ntawm kev lag luam thermal hloov tshuab, dav siv hauv roj & roj, kev ua tshuaj lom neeg, tsim hluav taws xob, thiab HVAC kev lag luam. Lawv txoj haujlwm txhim khu kev qha ncaj qha cuam tshuam rau kev siv hluav taws xob, kev tsim khoom txuas ntxiv, thiab cov nqi ua haujlwm. Lub qhov dej zoo- tuav lub plhaub thiab lub raj cua sov tuaj yeem txuas ntxiv nws txoj sia ntawm qhov nruab nrab 10-15 xyoo mus rau 20+ xyoo, thaum kev saib xyuas tsis zoo feem ntau ua rau muaj kev puas tsuaj tsis tu ncua, txo cov cua sov ua haujlwm, thiab hloov ntxov ntxov. Hauv qab no yog cov kws tshaj lij-rov qab saib xyuas thiab tu cov lus qhia kom ua kom lub neej ntev ntawm koj lub plhaub thiab lub raj cua kub exchanger, curated los ntawm GNEE tus kws tshaj lij thermal system.
1. Routine Preventive Maintenance: Lub Foundation of Lifespan Extension
Kev tiv thaiv kev saib xyuas yog qhov tseem ceeb rau kev txheeb xyuas cov teeb meem muaj peev xwm ua ntej lawv nce mus rau qhov ua tsis tau zoo. Tsim kom muaj lub sijhawm tshuaj xyuas raws li koj qhov kev ua haujlwm (xws li, siab -kub, corrosive media yuav tsum tau kuaj xyuas ntau zaus).
Ua ntej, saib xyuas cov haujlwm tseem ceeb txhua hnub. Taug qab qhov kub thiab txias sib txawv ntawm cov kua dej nkag thiab qhov hluav taws xob, lub siab poob thoob plaws lub plhaub thiab lub raj sab, thiab qib kev co. Kev poob siab tsis zoo feem ntau qhia tau tias fouling lossis blockages, thaum tsis muaj kev vibrations yuav qhia tau tias cov ntaub ntawv xoob xoob lossis cov baffles puas. Siv cov cuab yeej saib xyuas ntse rau tiag tiag - sijhawm sau cov ntaub ntawv - qhov no yuav pab saib xyuas kev kwv yees thiab zam lub sijhawm tsis tau npaj tseg.
Qhov thib ob, tshuaj xyuas cov gaskets thiab cov ntsaws ruaj ruaj tsis tu ncua. Leaks hauv gaskets tsis tsuas yog txo cov kev hloov hluav taws xob, tab sis kuj ua rau hla - cov kua dej paug, ua rau corrosion. Hloov cov roj hmab uas hnav lossis tawg nrog cov khoom siv siab- zoo, sib xws (xws li, EPDM rau tshuaj tiv thaiv, Viton rau qhov kub thiab txias) los xyuas kom meej lub foob kaw ntom nti. GNEE pom zoo kom kuaj xyuas gaskets txhua 3-6 lub hlis, nyob ntawm kev ua haujlwm siab thiab kub.
Thib peb, lubricate txav qhov chaw (yog tias tsim nyog). Rau cov khoom siv hluav taws xob sib hloov nrog cov baffles kho tau lossis cov khoom sib hloov, cov roj lubrication tsis tu ncua tiv thaiv kev sib txhuam- vim hnav. Siv cov roj nplua nyeem uas sib haum nrog cov txheej txheem dej thiab kev ua haujlwm ib puag ncig kom tsis txhob muaj kab mob.
2. Cov tswv yim tu kom zoo: Tiv thaiv Fouling thiab Corrosion
Fouling-sau ntawm cov deposits (scale, sludge, organic teeb meem) ntawm lub raj nto- yog tus yeeb ncuab loj tshaj ntawm lub plhaub thiab lub raj kub exchangers. Nws txo cov cua sov hloov coefficient, nce lub zog noj, thiab ua kom corrosion. Kev xaiv ntawm kev ntxuav yog nyob ntawm hom fouling thiab exchanger tsim.
ib. Tshuaj ntxuav
Kev ntxuav tshuaj yog zoo tagnrho rau tshem tawm cov nplai thiab cov organic fouling. Xaiv cov tshuaj ntxuav tau haum rau cov khoom siv raj (xws li, carbon steel, stainless hlau, titanium). Piv txwv li, cov tshuaj ntxuav kua qaub (hydrochloric acid-raws li) muaj txiaj ntsig zoo rau cov pob zeb hauv av, thaum cov tshuaj ntxuav alkaline ua haujlwm zoo rau cov organic deposits. Ib txwm ua qhov me me - ntsuas ntsuas ua ntej kom tsis txhob muaj cov khoom puas. Tom qab ntxuav cov tshuaj, ntxuav kom huv si nrog dej kom tshem tawm cov tshuaj seem - qhov no tiv thaiv corrosion ntxiv.
b. Kho tshuab ntxuav
Kev tu neeg kho tshuab yog tsim rau hnyav fouling lossis thaum tshuaj ntxuav tsis tau. Cov txheej txheem feem ntau suav nrog kev txhuam cov raj, rodding, thiab siab - tso dej siab. Rau cov raj finned, siv cov txhuam hniav kom tsis txhob ua rau cov fins puas. Siab -dej siab dav hlau (10,000-20,000 psi) yog qhov zoo rau kev tshem tawm cov ntaub ntawv nyuaj yam tsis muaj kev puas tsuaj rau lub raj. Xyuas kom tseeb tias cov cuab yeej ntxuav yog qhov loj me me rau cov raj kom tsis txhob khawb, uas tuaj yeem ua rau corrosion.
c. Tsis tu ncua tu zaus
Cov zaus ntxuav nws txawv raws li kev ua haujlwm. Rau cov txheej txheem kev lag luam nrog cov kua dej siab (piv txwv li, dej hiav txwv, roj av), ntxuav txhua 3-6 lub hlis. Rau cov ntawv thov tsawg dua (piv txwv li, HVAC cov tshuab dej tshiab), kev tu txhua xyoo yog txaus. Ua ib daim ntawv tu kom taug qab qhov ua tau zoo ntawm txhua qhov kev tu thiab kho lub sijhawm kom haum.
3. Tiv thaiv corrosion: Tiv thaiv cov khoom tseem ceeb
Corrosion yog ib qho tseem ceeb ua rau tsis ua hauj lwm ntxov hauv lub plhaub thiab lub raj cua kub exchangers. Txhawm rau tiv thaiv corrosion, pib nrog xaiv cov khoom tsim nyog rau qhov chaw ua haujlwm. Piv txwv li, siv stainless hlau los yog titanium rau corrosive kua (piv txwv li, acids, ntsev), thiab carbon steel rau tsis siv corrosive (xws li, huab cua, dej tshiab).
Siv cov tshuaj tiv thaiv rau lub plhaub thiab lub raj nplaim. Epoxy los yog polyurethane coatings tsim ib qho kev tiv thaiv corrosive media, ncua lub neej ntawm cov exchanger. Tsis tu ncua tshuaj xyuas cov txheej txheej rau cov kab nrib pleb lossis tev thiab kov raws li xav tau.
Tswj cov kua dej chemistry. Rau cov dej-raws li systems, tswj qhov tseeb pH theem (7-9) thiab siv corrosion inhibitors (xws li, chromates, phosphates) kom txo tau corrosion. Tshem tawm cov pa oxygen los ntawm cov kua dej (siv cov deaerators) los tiv thaiv cov pa oxygen-induced corrosion, uas muaj ntau hauv boiler feedwater systems.
4. Kev soj ntsuam thiab kho dua tshiab: Ua kom lub sijhawm ntev- Kev ntseeg tau ntev
Ntxiv nrog rau kev saib xyuas niaj hnub, teem caij kho dua tshiab txhua 2-3 xyoos. Kev kho dua tshiab suav nrog kev tshuaj xyuas cov ntawv raj rau cov kab nrib pleb, tshuaj xyuas cov raj kev ncaj ncees (siv tsis yog - txoj kev kuaj kev puas tsuaj xws li eddy tam sim no kuaj), thiab hloov cov hlab puas los yog baffles. GNEE pab pawg ntawm cov kws tshaj lij uas muaj ntawv pov thawj muab rau ntawm - qhov chaw thiab cov kev pabcuam kho dua tshiab, kom ntseeg tau tias koj lub tshuab hloov hluav taws xob ua tau raws li cov qauv kev lag luam thiab ua haujlwm ntawm qhov ua tau zoo tshaj plaws.
