Graphite gaskets yog dav siv nyob rau hauv ntau yam lag luam vim lawv zoo heev sealing kev ua tau zoo, kub tsis kam, thiab tshuaj stability. Raws li tus kws tshaj lij Graphite Gasket tsum, kuv muaj kev paub dhau los hauv daim teb no. Hauv qhov blog no, kuv yuav qhia qee qhov kev ceeb toom tseem ceeb rau graphite gaskets kom ntseeg tau tias lawv qhov kev ua tau zoo.
Kev npaj nto
Thawj thiab qhov tseem ceeb tshaj plaws hauv kev txhim kho graphite gaskets yog npaj cov mating nto kom zoo. Txhua yam av, xeb, lossis khib nyiab ntawm qhov chaw tuaj yeem tiv thaiv lub gasket los ntawm kev ua kom nruj. Siv cov tshuaj ntxuav kom tsim nyog kom tshem tawm tag nrho cov kab mob ntawm qhov chaw. Tom qab ntxuav, qhuav qhov chaw kom huv si kom tsis txhob muaj cov dej noo uas tuaj yeem cuam tshuam rau lub gasket qhov kev ua tau zoo.
Nws tseem yog ib qho tseem ceeb los xyuas qhov flatness ntawm mating nto. Txawm tias ib qho me me sib txawv ntawm flatness tuaj yeem ua rau qhov tsis sib xws ntawm kev faib tawm ntawm lub gasket, uas ua rau kom muaj dej. Yog hais tias qhov chaw tsis tiaj tus, lawv yuav tsum tau machined los yog hauv av kom ua tau raws li qhov yuav tsum tau flatness. Qhov roughness ntawm ib ncig ntawm 3.2 - 6.3 micrometers feem ntau pom zoo rau graphite gaskets.
Kev xaiv Gasket
Xaiv txoj cai graphite gasket rau daim ntawv thov tshwj xeeb yog qhov tseem ceeb. Xav txog yam xws li kev khiav hauj lwm kub, siab, tshuaj ib puag ncig, thiab flange hom. Rau siab - kub daim ntawv thov, nthuav graphite gaskets yog ib qho kev xaiv nrov vim lawv tuaj yeem tiv taus qhov kub txog li 550℃hauv oxidizing cua thiab txawm siab dua nyob rau hauv tsis yog - oxidizing atmospheres.
Yog tias daim ntawv thov cuam tshuam rau cov tshuaj corrosive, xyuas kom meej tias cov graphite gasket muaj cov tshuaj lom neeg tsim nyog. Qee cov graphite gaskets yog impregnated nrog cov ntaub ntawv tshwj xeeb los txhim kho lawv cov tshuaj tiv thaiv. Tsis tas li ntawd, qhov loj thiab thickness ntawm lub gasket yuav tsum phim lub flange qhov ntev precisely. Ib qho mob - fitting gasket tuaj yeem ua rau xau thiab tuaj yeem ua rau lub flange puas.
Kev tuav lub Gasket
Graphite gaskets yog qhov tsis yooj yim piv rau lwm hom gaskets. Thaum tuav lawv, ceev faj tsis txhob khoov, quav, lossis khawb lub gasket. Txhua yam kev puas tsuaj rau lub gasket tuaj yeem cuam tshuam nws lub peev xwm sealing. Ib txwm siv cov hnab looj tes huv los tswj lub gasket kom tsis txhob muaj cov pa paug los ntawm cov roj lossis av ntawm koj txhais tes.
Ua ntej kev teeb tsa, tshuaj xyuas lub gasket kom pom qhov tsis xws luag xws li tawg, kua muag, lossis qhov chaw tsis sib xws. Yog tias pom muaj teeb meem, tsis txhob siv lub gasket. Rov qab mus rau tus neeg muag khoom kom hloov pauv.
Txheej txheem installation
Positioning lub Gasket: Muab cov graphite gasket ua tib zoo rau ntawm qhov chaw flange, kom ntseeg tau tias nws yog nruab nrab thiab ua kom zoo. Lub gasket yuav tsum npog tag nrho cov sealing cheeb tsam ntawm lub flange yam tsis muaj overlapping los yog ncua tshaj lub flange npoo.
Bolt Tightening: Thaum zawm cov bolts, ua raws li kev nruj nruj. Ib txoj hauv kev zoo tshaj plaws yog siv lub hnub qub - zoo li tus qauv los yog lub voj voog nruj kom paub meej tias txawm tias qhov kev faib tawm ntawm lub gasket. Pib los ntawm nruj tag nrho cov bolts maj mam nyob rau hauv ib theem zuj zus, thiab maj mam nce lub torque nyob rau hauv ob peb kis.
Nws yog ib qho tseem ceeb uas yuav tau siv qhov tseeb torque tus nqi rau cov bolts. Tshaj - zawm lub bolts tuaj yeem ua rau lub gasket extrude, thaum nyob rau hauv - zawm tuaj yeem ua rau tawg. Xa mus rau cov chaw tsim khoom flange cov kev qhia tshwj xeeb lossis cov qauv kev lag luam rau qhov pom zoo torque qhov tseem ceeb. Piv txwv li, rau tus qauv 1 - inch diameter bolt hauv daim ntawv thov flange, tus nqi torque yuav nyob ntawm 20 - 40 Nm nyob ntawm cov khoom thiab qhov loj ntawm flange.
Zam Kev Twisting: Thaum lub sij hawm installation, xyuas kom meej tias lub gasket tsis twist. Twisting tuaj yeem ua rau qhov tsis sib xws ntawm kev faib tawm thiab ua rau kom xau. Yog hais tias lub gasket pib twist, nres lub installation, rov - tso lub gasket kom raug, thiab tom qab ntawd txuas ntxiv mus.
Ncej - Kev Tshawb Fawb
Tom qab lub gasket raug ntsia thiab cov bolts tau nruj, ua ib qho kev soj ntsuam tom qab - installation. Tshawb xyuas cov cim qhia ntawm gasket extrusion lossis misalignment. Tsis tas li, ua qhov kev ntsuas siab yog tias ua tau kom ntseeg tau tias lub gasket sealing zoo. Yog tias muaj qhov xau, txheeb xyuas qhov ua rau thiab ua kom raug. Nws tuaj yeem yog vim kev teeb tsa tsis raug, tsis raug xaiv gasket, lossis muaj teeb meem nrog cov mating nto.
Compatibility nrog lwm yam Cheebtsam
Graphite gaskets tuaj yeem cuam tshuam nrog lwm cov khoom hauv lub cev, xws li bolts, txiv ntseej, thiab flanges. Xyuas kom meej tias cov khoom no sib xws nrog cov graphite gasket. Piv txwv li, qee cov hlau yuav hnov mob nrog graphite nyob rau hauv tej yam kev mob, ua rau corrosion los yog degradation ntawm lub gasket. Hauv cov xwm txheej zoo li no, xav txog kev siv cov txheej txheem tsim nyog lossis cov khoom siv rau lwm cov khoom siv los tiv thaiv cov teeb meem kev sib raug zoo.
Cia
Kev khaws cia zoo ntawm graphite gaskets kuj tseem ceeb kom tswj tau lawv qhov zoo. Khaws cov gaskets nyob rau hauv ib qho chaw qhuav, huv si kom deb ntawm qhov chaw tshav ntuj ncaj qha thiab tshav kub. Tsis txhob khaws cia rau hauv thaj chaw uas muaj cov av noo siab vim tias cov av noo tuaj yeem cuam tshuam rau kev ua haujlwm ntawm lub gasket. Khaws cov gaskets nyob rau hauv lawv cov thawj ntim los yog nyob rau hauv ib lub thawv kaw kom tsis txhob muaj kab mob.
Yam khoom
