Thaum tshav kub kub exchanger yog dav siv nyob rau hauv cov cua sov thiab cua txias tshuab, ntau hom ntawm tshav kub exchangers yog tsuas yog plhaub thiab raj, volumetric, kauv, phaj, casing hom kub exchanger. Phaj kub exchanger tshwj xeeb corrugated zoo ntawm cov hlau phaj qauv, kom lub cev muaj zog turbulence, muaj peev xwm ntxiv dag zog rau ob sab ntawm cov kua kub hloov, nrog ib tug high heat hloov coefficient, adaptability, compact qauv, tu thiab dismantling ntawm yooj yim, saj zawg zog los ua ke zoo.
1 phaj kub exchanger qauv nta luv luv
Phaj kub exchanger feem ntau muaj xws li cov phaj kub exchanger, gasket, tsau npog, clamping bolts thiab lwm yam loj Cheebtsam.
Thaum tshav kub kub exchanger phaj yog ib txheej ntawm ib txwm mesh txaus phaj, hloov tau nrog ib leeg, cov phaj ntau muaj zigzag, kheej kheej, ncaj waveforms, thiab hais txog. Nruab nrab ntawm lub phaj los ntawm lub gasket rau kev sib cais, ob hom kua (kua A, kua B) nyob rau hauv lawv cov kav dej ntws thiab cov cua kub pauv ntawm lub tshav kub exchanger phaj.
2 phaj kub exchanger txheej txheem kev teeb meem tshwm sim
Phaj kub exchanger yog dav siv, high efficiency, tab sis cov qauv ntawm cov khoom kuj ua rau lub tshav kub exchanger phaj ntawm qhov nqaim yooj yim los thaiv, phaj puas, gasket kev pab cuam lub neej thiab lwm yam teeb meem, ua rau txo efficiency, muaj kev ruaj ntseg txaus ntshai. Plate heat exchanger hauv kev siv cov teeb meem uas tshwm sim feem ntau suav nrog cov ntsiab lus hauv qab no.
Gasket puas, kev laus. Feem ntau cov phaj gasket rau roj hmab thiab lwm yam ntaub ntawv, kev siv mus sij hawm ntev yuav tsum tau hloov tsis tu ncua, txwv tsis pub nws yuav ua rau cov roj hmab aging, sealing tsis nruj, cov kua dej ua kua tshwm sim.
Cov khoom xoob xws li daim npog ruaj ruaj thiab cov ntsia hlau clamping tuaj yeem ua rau cov kua dej tawm.
Scaling nyob rau hauv lub phaj. Scale ntawm lub phaj kub exchanger phaj hloov hluav taws xob muaj kev cuam tshuam zoo rau cov dej zoo tsis tsim nyog, cov kua dej hauv magnesium, calcium, carbonate thiab lwm yam kev cuam tshuam los tsim cov precipitates txuas rau muab tshuaj txhuam rau ntawm lub phaj, los yog muaj cov khoom tsis huv. tuaj yeem ua rau scaling hauv lub phaj.
Phaj tawg. Thaum tshav kub kub hloov cov kua yuav muaj cov khoom loj ntawm impurities, xws li xuab zeb, xeb, thiab lwm yam. uas txuas mus rau hauv lub phaj thiab gasket, tej zaum yuav yog vim muaj kev hloov pauv ntawm lub zog siab, kua corrosion los yog qaug zog tawg ntawm cov phaj hlau thiab lwm yam. on, ua rau lub tshav kub hloov phaj breakage.
Cov yeeb nkab corrosion. Phaj cua sov exchanger feem ntau muaj cov kua dej kub thiab tsis tshua muaj kub, feem ntau nrog kev txhim kho corrosion yog lub teeb, kev ua haujlwm ntev ntawm cov pob qij txha, cov kav dej sab nrauv yuav tshwm sim corrosion, yuav tsum tsis tu ncua nqa cov kav dej tiv thaiv corrosion thiab kev saib xyuas ntawm cov rwb thaiv tsev sab nrauv.
Kev ua haujlwm tsis raug ntawm tus neeg teb xov tooj. Tsis nruj me ntsis raws li cov txheej txheem, xws li cov cuab yeej disassembly gasket installation, lub tshav kub exchanger phaj piece misinstallation yuav ua rau ib tug poob ntawm efficiency.
3 phaj kub exchanger tu thiab txij nkawm piv txwv
3.1 Cov xwm txheej tseem ceeb ntawm qhov project
Tsev khaws puav pheej ntawm Science thiab Technology ntawm Tuam Tshoj phaj kub exchanger tag nrho ntawm 3, ntsia nyob rau hauv thawj pem teb tub yees chav tsev, cua kub exchanger kua ntawm ob sab: glycol tov ntshuam thiab export kub yog 2.5 degree / 11.3 degree, chilled dej ntshuam thiab export kub tau 13.3 degree / 4.5 degree, cov cuab yeej siv tau zoo phaj 423 daim. Txhawm rau kom ntseeg tau tias cov cuab yeej ua haujlwm ib txwm muaj thiab ua haujlwm tau zoo, kev sib xyaw ua ke ntawm kev tu txhua hnub thiab kev tu xyuas tsis tu ncua tau txais yuav. Lub siab thiab qhov kub thiab txias ntawm cov kua dej sab ntawm cov cuab yeej raug kaw tsis tu ncua txhua hnub.
3.2 Kev tu tsis tu ncua
(1) Cov txheej txheem ntxuav: ntxuav tus neeg saib xyuas → disassembly → tu → ziab → sib dhos → commissioning.
(2) Cov ntsiab lus ntawm kev siv tshuab ntxuav.
Kev xaiv tus neeg saib xyuas tu. Xaiv tus neeg saib xyuas kom tsim nyog, cov txheej txheem tu tus neeg saib xyuas yuav tsum tsis txhob ua kom puas, rhuav tshem lub gasket thiab stainless hlau phaj daim ntawv nto passivation zaj duab xis, yuav tsum tsis txhob siv chlorinated acid (xws li hydrochloric acid) tu cov cuab yeej, descaling pickling yuav siv nitric acid thiab thiaj li. ntawm.
Disassembly. Ua ntej disassembling lub phaj kub exchanger chav tsev, lub system siab nyem yuav tsum tau ua kom tiav, thaum lub sab hauv dej kub ntawm lub phaj kub exchanger yog txo kom qis dua 40 degree. Thaum disassembled lub phaj kub exchanger phaj daim yuav tsum khaws cov kab pheeb ces kaum nyob rau hauv thawj txoj hauj lwm, thiab ces tshem tawm cov seem bolts, cov khoom yog disassembled thaum lub taag compression phaj thiab movable compression phaj thiab lub phaj bundle tsis sib cais. Cov phaj yog npaj kom zoo thiab sau npe tom qab tshem tawm kom yooj yim rau kev sib dhos tom qab.
Ntxuav. Cov phaj tuaj yeem muab yaug nrog lub tshuab ntxhua khaub ncaws siab, txhuam txhuam, thiab lwm yam. Tsis muaj kev sib txhuam nyuaj xws li xuab zeb yuav tsum tau siv. Soak lub phaj hauv cov tshuaj ntxuav rau li 12h kom tshem tawm cov nplais tuab. Yaug thiab ntxuav nrog dej tom qab immersion. Cov kua uas siv los ntxuav cov khib nyiab yuav tsum tau thauj mus rau qhov chaw uas tau muab pov tseg.
Qhuav. Tom qab cov phaj tau muab tso rau kom qhuav tag, cov gaskets tau haum thiab lub rooj sib txoos tsuas yog nqa tawm tom qab ntawd.
Kev sib dhos. Ua ntej sib sau ua ke, xyuas kom cov gaskets ruaj ntseg ntsia, tias cov phaj raug ntxuav, thiab cov phaj tsis puas. Sib dhos thiab nias raws li daim ntawv lo ntawm lub phaj, thiab tiv thaiv kev sib dhos rov qab.
Kev ua haujlwm. Tshawb xyuas cov dej xau ua ntej pib. Txawm hais tias muaj me me ntawm cov dej xau thaum lub sijhawm pib pib, qhov xau yuav nres tom qab ua haujlwm li qub.
3.3 Kev hloov khoom siv
Txhawm rau tiv thaiv cov kua dej tawm thiab lwm yam tsis ua haujlwm, nws yog ib qho tsim nyog yuav tsum tau hloov txhua lub sijhawm ntawm cov gaskets thiab lwm yam khoom siv, thiab hloov cov phaj, bolts thiab lwm yam hnav thiab corroded raws li qhov chaw.
3.4 Rwb thaiv tsev thiab tiv thaiv corrosion
Phaj cua sov exchanger kav thiab cov khoom siv yuav tsum tau them rau hauv txheej rwb thaiv tsev sab nraud kom txo tau cov cua sov thiab tiv thaiv condensation ntawm sab nraud. Kev tshuaj xyuas txhua hnub ntawm kev rwb thaiv tsev, tiv thaiv corrosion thiab tiv thaiv txheej, dismantling ntawm cov khoom siv tom qab lub hauv paus hlau thiab thav duab los tiv thaiv corrosion thiab xeb tshem tawm, thermal rwb thaiv tsev thiab txias rwb thaiv tsev siv B1 qib roj hmab rwb thaiv tsev paj rwb, txheej tiv thaiv tuaj yeem siv nrog ib lub thickness ntawm 1.2 hli dov aluminium phaj.
4 Kev xaus
Txhawm rau kom tsis txhob muaj teeb meem xws li cov kua dej tsis zoo ntawm kev ua haujlwm ntawm cov khoom siv hluav taws xob sib pauv kev nyab xeeb thiab kev ua haujlwm zoo, Tuam Tshoj Science thiab Technology Tsev khaws puav pheej phaj kub exchanger ntawm ob sab ntawm cov kua hauv cov dej txias uas siv cov dej kho softened, glycol tov siv 25% glycol thiab 75% dej distilled, tab sis qhov tseeb disassembly thiab txij nkawm ntawm lub tshav kub exchanger phaj phaj yog tseem pom nyob rau ntawm ib tug me me ntawm nplai, sludge thiab mechanical impurities thiab lwm yam khib nyiab, tus neeg phaj tshwm nyob rau hauv lub qhov muag ntawm cov xuab zeb, sab nrauv. ncej hlau cheeb tsam ntawm cov khoom siv corrosion. Corrosion nyob rau hauv cov hlau cheeb tsam ntawm lub thav duab txheej ntawm cov khoom.
Raws li cov txheej txheem kev khiav hauj lwm rau kev ua haujlwm kom raug ntawm lub phaj kub exchanger, nkag siab txog cov khoom siv tsis ua haujlwm, kev tu tsis tu ncua, hloov gasket thiab kev saib xyuas yog tsim nyog.
