Yuav ua li cas tuav lub phaj kub exchanger gasket kom paub meej tias nws ua haujlwm zoo
Nyob rau hauv cov txheej txheem kev lag luam cov cuab yeej, phaj kub exchanger yog ib yam khoom uas muaj kev ruaj ntseg siab. Thaum lub gasket puas lawm, sab nraud drip yog pom. Thaum tshav kub kub exchangers thiab cov cua kub exchangers yuav muaj me ntsis to thaum pib, thiab nyob rau hauv cov txheej txheem cov khoom uas muaj kev cuam tshuam loj heev, cov dej xau loj yuav tshwm sim vim kev puas tsuaj ntawm lub sealing ncoo.
Txawm tias phaj kub exchanger, yuav muaj teeb meem nyob rau hauv lub chav kawm ntawm kev siv nyob rau hauv ib lub xyoo, yuav tsum tau kho, tshwj xeeb tshaj yog nws cov ntsaws ruaj ruaj, saib seb nws puas tau xoob. Daim ntawv no yuav qhia cov ntsiab lus rau kev saib xyuas ntawm cov phaj kub exchanger gasket.
Phaj heat exchanger yog ib qho tseem ceeb hauv kev sib pauv hluav taws xob ntawm cov txheej txheem kev lag luam. Lub elastic gaskets kaw ntawm txhua lub phaj kub dab dej yog ib yam ntawm cov khoom tsis zoo, thiab nyob rau hauv tej yam ntuj tso tej yam kev mob kuj yog ib yam ntawm cov yooj yim rau aging qhov chaw.
Nws lub neej kev pab cuam muaj qhov cuam tshuam tseem ceeb rau lub neej kev pab cuam ntawm phaj kub exchanger. Yog hais tias cov ntsaws ruaj ruaj yog hardened thiab poob qhov qub elasticity, lub tshav kub exchanger yuav tsis ua hauj lwm ib txwm.
Cov hauv qab no muaj feem cuam tshuam rau lub neej kev pab cuam ntawm lub elastic gasket:
■ Ua hauj lwm hom ntawm cov cua kub exchanger (nruam los yog tsis tu ncua)
■ Corrosivity ntawm cov xov xwm txias thiab cov tshuaj ntxuav siv siv
■ Ua haujlwm kub siab tshaj plaws
■ Ua haujlwm siab tshaj plaws
■ Kev ntxhov siab ntawm elastic gasket ntau dua vim qhov siab dhau thiab tsis sib npaug
■ Ntuj laus
Lub softening ntawm elastic gaskets muaj feem xyuam rau lub siab thiab kub. Thaum lub gasket poob nws elasticity, lub tshav kub exchanger yuav to.
Hauv qee cov khoom, txhawm rau daws qhov tshwm sim los ntawm kev laus ntawm lub sealing ncoo, tso cai rau kho qhov kev sib khi ntawm cov khoom siv hluav taws xob, uas yog, zawm lub ntsia liaj qhov rooj ntawm cov phaj sib xyaw ua ke dua, kho lub zog compression ntawm lub elastic sealing ncoo ntawm txhua lub tshav kub exchanger, los daws cov teeb meem drip. Nyob rau ntawm daim hlau ntawm cov khoom siv hluav taws xob nrog cov haujlwm no, qhov siab tshaj plaws thiab qhov tsawg kawg nkaus tso cai rau kev ntxhov siab feem ntau tau muab.
Rau cov ntaub ntawv hloov hluav taws xob tshiab, qhov tsawg kawg nkaus tso cai yuav tsum tau siv rau kev sib txuas thiab kho. Nyob ntawm seb tus naj npawb ntawm cov ntawv sib hloov hluav taws xob hauv txhua lub teeb, lub zog nruj ntawm cov khoom siv hluav taws xob tuaj yeem hloov kho ib zaug lossis ntau zaus. Txhua qhov nruj, koj tuaj yeem ntsia hlau ntsia hlau hauv 3 hli, thiab ib txwm ua tib zoo saib xyuas cov kev ntxhov siab ntawm cov phaj tswj thaum lub sijhawm ua kom nruj. Ntxiv mus, tsuas yog lub tshav kub exchanger uas tsis ua hauj lwm siab yog tso cai rau kho lub zawm quab yuam ntawm chav tsev kub kom tsis txhob poob.
Rau lub phaj kub exchanger uas nws txoj kev ntxhov siab ntau yam tsis tau muab rau hauv daim ntawv teev npe, qhov kev ntxhov siab feem ntau yog muab rau hauv qhov kos duab. Thaum nruj no hom phaj kub exchanger, lub zawm torque yuav tsum tsis txhob qis dua tus nqi teev nyob rau hauv daim duab nyob rau hauv txhua rooj plaub. Vim tias nws muaj feem xyuam rau kev sib dhos zoo thiab deformation ntawm phaj kub exchanger. Thaum lub torque nruj mus txog qhov yuav tsum tau ntawm tus nqi teev, lub elastic gasket tuaj yeem hloov tau raws li kev npaj.
Rau phaj kub exchangers siv nyob rau hauv neutralizing corrosive xov xwm ntawm cov khoom tseem ceeb ntau lawm, nws yog pom zoo kom muaj ib tug txheej ntawm spare seals. Thaum lub warehouse kub yog 18 degree, cov ntsaws ruaj ruaj ntawm phaj kub exchanger yuav khaws cia rau li 3 xyoos nyob rau hauv pob tshab ntim yas.
Fixation ntawm cov ntsaws ruaj ruaj
Raws li txoj cai, kev kho cov ntsaws ruaj ruaj tuaj yeem muab faib ua ob pawg: kev kho cov nplaum thiab tsis nplaum. Cov duab ntawm lub gasket yuav tsum ua raws li cov duab ntawm lub phaj kub exchanger foob. Nws yuav tsum raug sau tseg tias txoj kev kho cov nplaum nplaum tsis muaj qhov cuam tshuam rau kev sib khi ua haujlwm.
Tsis-adhesive seal
■ Kev sib dhos: Muab lub nplhaib sib khi rau hauv qhov chaw
■ Muab tso rau hauv: Ua kom lub nplhaib sealing nkag mus rau hauv qhov sib khi kom raug
■ Nias kom ruaj khov: hauv lub tank kaw. Ib tug zawj qauv nrog ib tug txo tus ntoo khaub lig seem. Yog li ntawd lub nplhaib foob yog positioned kom raug
Adhesive hom foob
Raws li lub hom phiaj ntawm gasket thiab sealing zoo yuav tsum tau, sib txawv manufacturers ntawm blended sealant thiab non-blended sealant yuav siv tau. Ua ntej kev sib txuas, cov nplaum nplaum thiab cov seem gasket yuav tsum tau muab tshem tawm kom huv si los ntawm kev sib koom ua ke siv cov pa cua.
Rau kev sib xyaw sealant sib txuas, cov nplaum nplaum thiab cov seem seem ntawm cov khoom sib txuas ntawm cov phaj kub exchanger yuav tsum tau hlawv tawm. Rau qhov ntau ntawm kev sib txuas, lub pas dej ua kua nitrogen rau cov ntsaws ruaj ruaj thiab lub qhov cub cua sov kom qhuav lub phaj kub exchanger nrog lub sealing ncoo yuav tsum tau npaj ntawm qhov kub thiab txias ntawm 160 degree. Yog hais tias ua tau, lub phaj kub exchanger yuav tsum tau muab ntxuav kom huv si kom paub meej tias lub gasket ntawm cov nplaum seem nyob rau hauv lub sib koom nto ntawm lub phaj kub exchanger yog kiag li tshem tawm.
Raws li cov muv chamber soj ntsuam qhov ntawm phaj kub exchanger kom paub seb lub installation ntawm gasket puas yog
Kev sib txuas ntawm cov phaj kub hloov pauv yuav tsum tau ntxuav nrog cov tshuaj ntxuav (xws li acetone). Ib yam li ntawd, cov tshuaj ntxuav tes yuav tsum tau siv los tshem tawm cov softener thiab anti-adhesion txheej bonded ntawm lub sealing gasket, thiab cov nplaum yog siv rau hauv nruab nrab ntawm txhua qhov sib txuas.
Qhov dav ntawm cov nplaum yuav tsum yog hais txog qhov dav ntawm qhov sib tw, nyob ntawm qhov dav ntawm lub gasket. Tom qab ntawd, siv cov txhuam hniav kom nthuav tawm cov nplaum sib npaug thoob plaws tag nrho cov khoom sib txuas kom siv tag nrho cov khoom sib txuas. Raws li qhov sib txawv ntawm cov nplaum nplaum, tos rau qee qhov cua thiab ziab lub sij hawm, thiab tom qab ntawd muab tso rau hauv lub sealing ncoo, ntau lub phaj kub exchangers yog stacked ua ke, nruj nrog ib tug tensioning ntsia hlau, los yog nias rau ntawm stacked heat exchanger pawg. nrog hnyav hnyav.
Lub sij hawm hardening yog li ntawm 8-20 teev nyob ntawm seb hom nplaum. Rau cov nplaum sib xyaw, cov ntsia hlau nro thiab cov cua sov cua sov yuav tsum tau nqa tawm.
