Nws yog ib qho yooj yim rau to, tawg, laus, deformation, thaum phaj kub exchanger tom qab siv ntev los yog tsis tu ncua.thaum tus neeg siv pom cov xwm txheej no, peb yuav tsum hloov lub gasket kom raws sij hawm, thiaj li tsis mus. ua rau muaj txim loj dua. Nyob rau tib lub sij hawm, tus neeg siv nyob rau hauv kev siv niaj hnub ntawm phaj kub exchanger, tab sis kuj yuav tsum tsis tu ncua ntxuav lub internal roj hmab ncoo, uas yuav ncua nws cov kev pab cuam lub neej, txo qhov tshwm sim ntawm tsis ua hauj lwm. Tom ntej no, kuv yuav muab cov hais mav hais tias phaj kub exchanger pad hloov thiab tu cov kauj ruam:
Raws li cov phaj kub exchanger daim ntawv thov teb tau nthuav dav, rau cov xov xwm sib txawv thiab cov txheej txheem muaj qhov sib txawv ntawm qhov kub, siab thiab corrosion kuj. Xav siv lub "universal" gasket kom haum rau txhua qhov xwm txheej, pom tseeb tsis yooj yim sua, thiab yuav tsum tau siv rau cov xwm txheej sib txawv nrog cov khoom sib txawv gasket. Feem ntau siv gasket cross-section zoo rau lub hexagon. Feem ntau siv hom gaskets yog cov roj hmab ntuj, neoprene roj hmab, butyl roj hmab, EPDM roj hmab, silicone roj hmab, fluorine roj hmab, asbestos fiber ntau thiab lwm yam. Phaj heat exchanger gaskets yuav tsum tau hloov raws sij hawm yog tias muaj kev sib tsoo, tawg, kev laus, thiab lwm yam tshwm sim thaum siv. Kev hloov pauv yuav tsum tau ua raws li hauv qab no.
Tshem lub gasket pov tseg. Ceev faj tsis txhob khawb qhov gasket zawj thaum tshem tawm. Siv acetone, butanone lossis lwm cov kuab tshuaj ketone, tshem tawm cov nplaum seem ntawm lub qhov gasket. So lub shim zawj thiab shim nrog ib daim ntaub huv si los yog paj rwb gauze. Siv cov nplaum sib npaug rau qhov gasket zawj. Siv lub shim tshiab huv si rau lub rooj tsavxwm. Lub phaj nrog gasket affixed yuav tsum muab tso rau hauv ib lub tiaj, txias thiab ventilated qhov chaw kom qhuav rau 4h ua ntej installation thiab siv.
Cov roj hmab qub tshem tawm thiab ntxuav cov txheej txheem
Cov phaj feem ntau yog ntxuav los ntawm txhais tes thiab tshuaj, thiab yuav tsum tsis txhob shoveled nrog cov cuab yeej ntse kom tsis txhob khawb cov phaj. Kev txhim kho thiab kev saib xyuas kom raug yog ib feem tseem ceeb ntawm kev ua kom muaj kev nyab xeeb thiab ua haujlwm ntawm cov cua sov. Piv txwv li, herringbone corrugated phaj yuav tsum tau xaiv sib txuas los yog buckle hom gasket thiab sib txawv, kev xaiv ntawm buckle hom gasket yuav pab tau kom tsis txhob cov kua nplaum yuav muaj chloride ions ntawm corrosion ntawm lub phaj, thiab cov khoom disassembly thiab installation yog yooj yim dua. Txawm li cas los xij, vim tias lub phaj kub hloov pauv qhov chaw hla ntu me me, xws li kev saib xyuas raws sij hawm, tej zaum yuav raug tsim los ntawm scaling blockage, cuam tshuam rau kev siv cov khoom siv thiab kev siv ib txwm muaj. Tsis tas li ntawd, koj tuaj yeem xaiv los siv lub tshuab hluav taws xob cua sov, tab sis yuav tsum nruj me ntsis tswj cov nplaim taws mus rau hauv qab ntawm phaj ntu ntawm 10-15cm, aluminium alloy phaj yuav tsum tau them sai sai rau!
