Taw qhia:
Flange kev sib txuas yog ib qho tseem ceeb ntawm ntau yam kev lag luam, kom ntseeg tau tias cov kav dej thiab cov khoom siv tau ruaj khov ua ke. Txawm li cas los xij, kev sib txuas flanges kom raug yog qhov tseem ceeb los tiv thaiv kev xau, tswj kev ua haujlwm siab, thiab ua kom muaj kev nyab xeeb tag nrho ntawm kev ua haujlwm. Nyob rau hauv phau ntawv qhia no, peb yuav tshawb nrhiav qhov zoo tshaj plaws thiab tsis zoo flange kev twb kev txuas koj yuav tsum paub. Txawm hais tias koj yog ib tus kws tshaj lij lossis nyuam qhuav pib, kev paub txog kev sib txuas ntawm flange yog qhov tseem ceeb rau kev ua haujlwm tiav.
1. Nkag siab txog Flange Connection Method:
Flange kev twb kev txuas yog ib tug dav siv cov txheej txheem uas muaj kev txuas ntawm ob lub flanges cais nrog bolts, tsim ib qho kev sib koom ua ke. Cov flanges ua raws li cov khoom sib txuas, muab cov ntaub ntawv pov thawj thiab ruaj khov ntawm cov kav dej lossis cov khoom siv. Ua ntej pib txoj kev sib txuas, nws yog ib qho tseem ceeb uas yuav tau xaiv cov flange uas tsim nyog, suav nrog lub ntsej muag, lub ntsej muag tiaj tus, lossis lub nplhaib sib koom ua ke, thiab xyuas kom meej tias lawv nyob hauv qhov zoo.
2. Flange Connection txheej txheem piav qhia:
Thaum nws los txog rau kev sib txuas flanges kom raug, ua raws li cov txheej txheem ua haujlwm yog qhov tseem ceeb tshaj plaws. Ua ntej thiab qhov tseem ceeb tshaj plaws, xyuas kom meej tias qhov chaw flange huv si thiab tsis muaj cov kab mob los yog cov khib nyiab. Tom qab ntawd, kho cov ntsia liaj qhov rooj ntawm ob lub flanges thiab ntxig cov bolts, kom ntseeg tau tias lawv phim cov ntsia liaj qhov rooj zoo kawg nkaus.
Tom ntej no, siv lub sealing zoo ntawm ob lub ntsej muag flange. Kev xaiv ntawm cov khoom siv gasket nyob ntawm cov kev cai tshwj xeeb, xws li siab, qhov kub thiab txias, thiab tshuaj lom neeg sib raug zoo. Tighten lub bolts maj mam nyob rau hauv ib tug ntoo khaub lig-hom, tswj ib tug txawm tis ntawm load ntawm lub flange kev twb kev txuas. Nws yog ib qho tseem ceeb kom ua raws li cov chaw tsim khoom cov lus qhia rau bolt nruj torque qhov tseem ceeb kom tsis txhob dhau-tightening los yog under-tightening.
3. Feem ntau yuam kev kom zam:
Thaum txuas flanges, nws yog ib qho tsim nyog yuav tsum tau ceev faj txog qhov muaj peev xwm pitfalls uas yuav cuam tshuam qhov kev sib koom ua ke. Ib qho yuam kev feem ntau yog siv cov khoom siv gasket tsis raug lossis rov siv cov khoom qub qub, ua rau cov dej xau. Ib txwm xaiv lub gasket uas tsim nyog rau kev ua haujlwm tshwj xeeb ntawm koj daim ntawv thov thiab hloov nws thaum twg tsim nyog.
Lwm qhov yuam kev tseem ceeb yog kev faib tsis sib npaug ntawm cov ntsia liaj qhov rooj thaum lub sijhawm zawm. Kev nruj nruj tsis sib xws tuaj yeem tsim cov xau thiab ua rau flanges rau warp lossis deform thaum lub sijhawm. Kev cob qhia kom raug thiab ua raws li qhov ntsuas torque yuav pab kom tsis txhob muaj qhov pheej hmoo no. Tsis tas li ntawd, kev siv cov ntsia liaj qhov rooj tsis raug lossis qhov sib xyaw metric thiab cov qauv bolts yuav tsum raug zam ntawm txhua tus nqi.
4. Qhov tseem ceeb ntawm Flange Connection Integrity:
Qhov tseeb flange txuas txheej txheem ncaj qha cuam tshuam rau tag nrho kev ncaj ncees thiab kev ua tau zoo ntawm txhua qhov system. Los ntawm kev ua kom ntseeg tau qhov tseeb thiab tsis muaj flange kev sib txuas, koj tiv thaiv txhua yam kev phom sij lossis kev pheej hmoo cuam tshuam nrog cov kua dej poob, kev sib kis ntawm ib puag ncig, lossis kev cuam tshuam cov cuab yeej ua haujlwm. Ib qho kev sib txuas flange txhim khu kev qha ua rau txo qis txij nkawm thiab txhawb kev ua haujlwm zoo, txhawb nqa tag nrho cov nqi-zoo.
5. Xaus:
Mastering cov kos duab ntawm kev sib txuas flanges tsis tsuas yog ua kom muaj kev sib koom ua ke txhim khu kev qha thiab tsis muaj paug, tab sis kuj lav qhov kev nyab xeeb thiab kev ua haujlwm ntawm ntau yam kev lag luam. Los ntawm kev nkag siab txog txoj kev sib txuas ntawm flange thiab zam kev ua yuam kev, koj tuaj yeem tsim kom muaj kev sib txuas ruaj khov uas tiv taus qhov kev sim ntawm lub sijhawm. Nco ntsoov xaiv hom flange tsim nyog, siv cov khoom siv gasket kom raug, thiab ua raws li cov chaw tsim khoom cov lus qhia rau bolt zawm. Nrog rau kev cob qhia kom raug thiab ua tib zoo saib xyuas kom meej, koj yuav paub txog kev sib txuas flanges kom raug, cuam tshuam rau kev ua tiav thiab kev ncaj ncees ntawm koj cov haujlwm.
