Phaj tshav kub exchanger nyob rau hauv lub sij hawm ntev, lub lubrication ntawm tshav kub hloov nyob rau hauv ib tug loj heev xov xwm tsis corrosive, tsis tas yuav txhawj txog phaj kub exchanger phaj corrosion thiab roj hmab gaskets los tsim o, laus thiab lwm yam mob. Tab sis cov tshuaj phaj kub exchanger daim ntawv thov nruab nrab, ntxiv rau cov dej, feem ntau ntawm cov neeg pluag, nplua nuj kua thiab sodium hydroxide, sulfuric acid thiab lwm yam chemical media, yooj yim los ua phaj kub exchanger phaj corrosion thiab roj hmab gasket o, aging, yog li lub tag nrho cov txheej txheem ntawm kev xaiv ib txwm them sai sai rau lub phaj thiab cov khoom siv roj hmab gasket yog qhov tsim nyog rau nws qhov nruab nrab, sealing rubber gasket khoom xaiv yog qhov tseem ceeb tshwj xeeb.
Plate heat exchanger phaj xaiv cov khoom siv
1, dej huv, dej ntws, roj noj, roj ntxhia thiab lwm yam xov xwm, cov khoom siv phaj feem ntau yog xaiv stainless hlau (AISI 304, AISI 316, thiab lwm yam).
2, seawater, dej ntsev, saline thiab lwm yam xov xwm, phaj cov ntaub ntawv feem ntau xaiv titanium thiab titanium-palladium (Ti, TiPd).
3, dilute sulfuric acid, dilute sulfur ntsev aqueous tov, inorganic aqueous tov thiab lwm yam xov xwm, phaj xaiv 20Cr, 18Ni, 6Mo (254SMO) thiab lwm yam alloys.
4, kub siab, siab concentration ntawm caustic soda media, phaj khoom xaiv ntawm nickel Ni.
5, concentrated sulfuric acid, hydrochloric acid, phosphoric acid nruab nrab, phaj khoom xaiv HASTELLOY alloy (C276, D205, B20).
Phaj kub exchanger roj hmab gasket khoom xaiv
Feem coob ntawm cov neeg nkag siab txog cov roj hmab sealing gasket feem ntau siv rau EPDM, roj hmab nitrile, hydrogenated nitrile roj hmab, fluorine roj hmab thiab lwm yam.
EPDM: kev siv kub -25 ~ 180 degree, haum rau cov kua nruab nrab kub dej, dej vapour, atmospheric ozone, uas tsis yog-petroleum-based lubricants, tsis muaj zog acids, tsis muaj zog bases, ketones, cawv, esters thiab hais txog.
Nitrile roj hmab NBR: kev siv kub -15 ~ 130 degree, haum rau cov kua nruab nrab lub teeb thiab hnyav roj roj thiab lwm yam roj ntxhia roj, lubricants, tsiaj thiab zaub roj, dej kub, dej ntsev thiab lwm yam.
Hydrogenated nitrile roj hmab HNBR: kev siv kub yog -15 ~ 160 degree, haum rau cov kua nruab nrab kub kub dej, roj crude, sulfur-muaj roj thiab organic sulfur tebchaw, ib feem ntawm lub tshav kub hloov roj, lub tshiab refrigerant R134a, ozone ib puag ncig.
Fluorine roj hmab FKM: kev siv kub -15 ~ 200 degree, haum rau cov kua nruab nrab concentrated sulfuric acid, caustic soda, tshav kub hloov roj, roj uas muaj cawv, acidic roj, high-temperature dej vapor, dej chlorine , phosphate, thiab lwm yam.
Cov txheej txheem kev lag luam tshuaj lom neeg hauv nruab nrab yog qhov nyuaj dua, tshwj xeeb tshaj yog muaj ntau yam tshuaj lom neeg sib xyaw nrog cov kua nruab nrab, nyob rau hauv ib qho kub, siab tej yam kev mob yuav tshwm sim nyob rau hauv cov tshuaj tiv thaiv los tsim cov tshuaj tshiab.
Thaum tsis muaj roj hmab sealing gasket nyob rau hauv ib tug tej yam sib tov ntawm cov xov xwm nyob rau hauv kev siv ntawm kev paub, yuav tsum tau ua ntej mus sawv ntawm lub gasket immersion xeem, cov roj hmab sealing gasket raus nyob rau hauv nruab nrab los ntsuas qhov expansion ntawm lub gasket, hardness thiab rhiab heev. rau chemical corrosion. Raws li ISO 15547-1-2005 Cov Lus Qhia Ntxiv Ib Daim Ntawv Qhia Ntxiv, qhov kev ntsuam xyuas nrog qhov siab tshaj plaws ntawm 8 hli tuab cov khoom siv gasket nyob rau hauv lub gasket ntawm qhov kub thiab txias ntawm qhov kev xeem, qhov tsawg kawg nkaus lub sij hawm ntawm kev xeem rau 15 hnub. Txiav txim siab seb cov roj hmab sealing gasket hauv nruab nrab puas haum rau tus qauv: roj hmab sealing gasket khoom hardness hloov tsis tshaj 10 IRHD (fluorine roj hmab gasket hardness yuav tsum tsis pub tshaj 15 IRHD) (IRHD rau lub thoob ntiaj teb roj hmab hardness unit), lub ntim hloov yuav tsum tsis pub tshaj 15 feem pua.
Tab sis vim tias tam sim no kev lag luam xav tau rau roj hmab gaskets hnyav, thiab xyoo no, cov roj hmab hluavtaws, carbon dub thiab lwm yam khoom siv raw cov nqi, muaj qee cov khoom lag luam gasket kom muaj sia nyob zoo dua yog tsis kho cov nqi, tsuas yog txo cov nqi yuav tsis poob nyiaj, tsuas yog qhov thib ob zoo tshaj plaws, ntxiv rau qee cov tshuaj ntxiv yuav ua rau cov khoom siv raw ntawm cov nroj tsuag tshuaj, nws yog cov muaj pes tsawg leeg ntawm gasket thiab cov txheej txheem ntawm kev ua tau zoo ntawm cov kev cai nruj kom ntseeg tau tias nws ncav cuag cov tshuaj nrog lub phaj kub exchanger ua haujlwm. kev cai thov kev cai.
Cov no yog cov tshuaj phaj kub exchanger xaiv los them tshwj xeeb rau qhov chaw, yuav tsum tau xaiv scientific thiaj li yuav xyuas kom meej cov kev siv ntawm cov tom ntej phaj kub exchanger khoom!
