Nws yog feem ntau ua tau kom paub seb lub tshav kub exchanger foob yog tawm ntawm qhov kev txiav txim los ntawm dripping thaum lub sij hawm txias txav ntawm lub phaj kub exchanger los yog poob thaum lub sij hawm nres tsheb thiab txias, tab sis ib co phaj kub exchangers tam sim no muaj ib tug re-adjustable muaj nuj nqi, uas txhais tau hais tias. cov pab pawg neeg sib pauv cua sov tuaj yeem ntsia tau ua ke ob zaug thaum muaj qhov dej me me, kom ua tiav qhov kev ntxhov siab ntawm cov gaskets thiab daws qhov tshwm sim ntawm cov dej ntws hauv lub sijhawm luv luv. Hauv cov khoom siv hluav taws xob sib xyaw ua ke tshiab, qhov sib xyaw ua ke loj dua tuaj yeem siv tau thiab thaum muaj dej tshwm sim, cov pab pawg ntawm cov phaj kub hloov pauv tau nruj. Qhov siab tshaj plaws thiab qhov tsawg kawg nkaus qhov sib xyaw ua ke ntev yog feem ntau pom ntawm lub tshav kub exchanger nameplate. Nws yuav tsum tau muab sau tseg tias qhov tsawg kawg nkaus ua ke ntev yuav tsum tsis txhob tsawg tshaj li qhov tsawg kawg nkaus ua ke ntev loj. Thaum cov khoom sib xyaw ua ke mus txog qhov tsawg kawg nkaus qhov sib xyaw ua ke ntev thiab tseem drips, nws txhais tau tias lub gasket yuav tsum tau hloov. Cov yam tseem ceeb cuam tshuam rau lub neej kev pab cuam ntawm cov roj hmab gasket yog txoj kev sib hloov cua sov ua haujlwm, corrosive yam ntawm cov xov xwm thiab cov neeg ua haujlwm tu siv, qhov siab tshaj plaws ua haujlwm kub, siab tshaj plaws ua hauj lwm siab, siab zog ntawm elastic gasket vim ntau dhau thiab tsis sib npaug siab, thiab ntuj laus. Cov no yuav tsum tau khaws cia thiab muab kev pabcuam lossis hloov pauv hauv lub sijhawm zoo.
Cov kauj ruam tseem ceeb rau kev rov siv dua thiab hloov cov roj hmab gaskets yog
A, phaj kub exchanger rov qab siv ua ntej kev tshuaj xyuas thiab tu:
1, Tshawb xyuas cov phab ntsa thickness ntawm lub tshav kub exchanger thiab cov kav dej nyob rau hauv cov ntaub ntawv ntawm xav tias corrosion.
2, tshem tawm cov ntsaws ruaj ruaj, raws li cov av sib txawv, siv cov kua qaub thiab alkali rau tshuaj ntxuav, qhov chaw ntawm cov khoom ntxuav yuav tsis raug corroded los ntawm tshuaj lom neeg.
3, Tom qab cov tshuaj ntxuav tu, siv lub tshuab nqus tsev siab kom huv si tshem tawm cov tshuaj lom neeg tawm ntawm qhov chaw ntawm lub phaj kub exchanger thiab hauv cov kav dej.
4. Lub tshav kub exchanger phaj yog coated nrog ib tug fluorescent xeem tus neeg saib xyuas thiab xyuas rau cov me me tawg thiab corrosion qhov nyob rau hauv UV teeb thiab ntxuav dua.
5, tseem tsom rau kev tshuaj xyuas qhov xwm txheej ntawm qhov sib khi zawj, yog tias tsim nyog los txiav.
Thib ob, lub tshav kub exchanger sealing gasket rov qab siv ua ntej kev tshuaj xyuas thiab tu:
1, xyuas seb qhov chaw ntawm lub gasket yog daig nrog cov impurities uas tsis yog roj hmab, yog tias yuav tsum tau tshem tawm, thiab yuav tsum tsis txhob muaj kev puas tsuaj me ntsis rau lub gasket;
2, saib seb lub gasket puas pom tseeb indentation, los yog lub zos thickness yog obviously thinner tshaj lub zuag qhia tag nrho thickness, yog hais tias xws li tshwm sim, thov tso tseg tag nrho;
3, Sib piv lub gasket nrog lub gasket qhov, saib seb puas muaj qhov ntev ntawm ntau tshaj 8 hli, los yog qhov ntev ntawm 3mm tawm ntawm lub qhov gasket, yog tias koj pom cov xwm txheej zoo li no, thov tsis lees txais lawv txhua tus.
4, Rau cov nplaum nplaum, cov khoom seem yuav raug tshem tawm kom huv si thiab rov ua dua tshiab siv cov nplaum nplaum sib xyaw. Lub reassembled cua sov exchanger teeb yuav tsum clamped nyob rau hauv ib tug tshwj xeeb fixture los kho cov nplaum thiab rhuab nyob rau hauv ib tug kub preservation qhov cub kom ua tau zoo tshaj plaws nplaum nyhuv.
Thib peb, reassemble lub tshav kub exchanger unit.
Nyob rau hauv cov txheej txheem kev lag luam cov cuab yeej, lub phaj kub exchanger yog ib daim ntawm cov khoom uas muaj kev ruaj ntseg yuav tsum tau thiab thaum lub gasket puas lawm, sab nraud drips yog pom. Kev siv rov qab ua haujlwm ntawm Cov Hluav Taws Xob Hluav Taws Xob yog pib ua rau me me dripping thiab hauv cov txheej txheem cov khoom siv nrog kev kub ntxhov, cov xau loj tuaj yeem tshwm sim vim kev puas tsuaj rau gasket. Yog vim li cas rau qhov no yog tias nyob rau hauv lub siab muaj zog shocks lub gasket tej zaum yuav tawg tawm ntawm qhov tseeb phaj gasket zawj ntawm lub phaj kub exchanger, los yog nyob rau hauv mob hnyav txawm tuaj tawm ntawm lub tshav kub exchanger.
Nyob rau hauv tas li ntawd, lub tshav kub exchanger yuav tsum tau kaw tam sim ntawd thiab tso cai rau txias mus rau chav tsev kub tsis muaj siab. Yog hais tias lub gasket uas tau raug lub zog siab poob siab tau mus tas li deformed, lub gasket tsis tuaj yeem rov qab los rau nws qhov qub thiab loj thiab poob nws cov khoom sib khi, qhov twg nws yuav tsum tau hloov nrog lub gasket tshiab.
Yog tias tsis muaj cov roj gasket, qhov kev ntsuas kub ceev ib ntus yog tshem tawm cov gasket puas ntawm tag nrho cov phaj kub exchanger phaj thiab cov phaj uas nyob ib sab (ob daim hlau tag nrho), xyuas tag nrho cov gasket qhov chaw kom paub meej tias tsis muaj qhov cuam tshuam rau lub foob. xws li impurities, kab nrib pleb thiab lwm yam. thiab tom qab ntawd nruab qhov seem ntawm cov khoom siv hluav taws xob sib txawv raws li cov piv txwv hauv cov lus qhia ua haujlwm. Txhawm rau kom ntseeg tau tias cov khoom siv hluav taws xob tuaj yeem siv rau lub sijhawm luv luv, nws yog ib qho tsim nyog los xyuas kom meej tias muaj kev sib khi txaus. Qhov no yog ua los ntawm kev xam qhov tseeb clamping qhov ntev. General empirical qhov tseem ceeb yog
Clamping loj {{0}} (phaj tuab ntxiv rau gasket thickness) x tooj liab x 0.72
