Kev ceev faj rau kev siv LAP flanges
Jul 28, 2025| Ib ceg tawv flange (tseem hu ua khau khiab ...-} ntawm flange) yog lub bolted, kuj rotatable flange qauv. Nws yog feem ntau siv nyob rau hauv cov kav dej uas nquag disassembly lossis thermal exporsion them yog yuav tsum tau. Nws qhov hloov tau yooj yim thiab yooj yim ua rau nws siv dav hauv kev lag luam xws li tshuaj lom neeg, roj av, thiab hluav taws xob kev lag luam. Txawm li cas los xij, cov kev ceev faj hauv qab no yuav tsum pom nruj me ntsis pom thaum kev teeb tsa thiab siv kom muaj kev nyab xeeb thiab kev ntseeg tau.
1. Cov khoom siv thiab cov lus qhia tshwj xeeb
Cov khoom ntawm ceg tawv pojniam (xws li cov hlau steel, stainless hlau, lossis alloy steel hlau) yuav tsum phim cov kev ua haujlwm nruab nrab, kub thiab kev ntsuas siab ntawm cov raj txheej txheem. Kev xaiv tsis raug cai yuav ua rau corrosion, deformation, lossis xau. Tsis tas li ntawd, cov kabinal lub diaminal thiab siab li pn10 lossis chav kawm 150) ntawm flange yuav tsum tsis txhob muaj kev nyab xeeb rau kev nyab xeeb tsis meej.
2. Kev teeb tsa muaj kev teeb tsa
Thaum lub sij hawm teeb tsa, ua ntej ntxig lub ceg tawv taub hau rau ib qho kawg ntawm cov yeeb nkab, tom qab ntawd txuas nws rau cov flange flange (lossis khoom siv sib cuam tshuam) nyob rau lwm qhov kawg. Bolts yuav tsum tau ua kom nruj cov pheeb ces kaum, los ua ib kauj ruam, kom ntseeg tau tias lub zog hluav taws xob thiab tiv thaiv flange lub ntsej muag defection lossis gasket puas tsuaj. Yuam kev sib dhos yog nruj me ntsis txwv kom tsis txhob muaj kev puas tsuaj rau cov xov los yog cov chaw sib khi.
3. Gasket xaiv thiab txij nkawm
Xaiv cov gaskets tsim nyog (xws li roj hmab, graphite, lossis muab cov pa tawm kom paub tseeb, thiab ua kom cov gaskets yog cov khawb hauv, kev laus, lossis lwm yam tsis xws luag. Tom qab siv txuas ntxiv, nquag tshuaj xyuas cov gaskets thiab hloov lawv kom sai yog tias txeej lossis deformation raug kuaj pom.
4. Anti {{{{{}} xoob thiab anti - corrosion ntsuas
Bolts tuaj yeem daws tau yooj yim hauv qhov siab - kub lossis vibrating ib puag ncig. Nws raug nquahu kom siv lub caij nplooj ntoo hlav lossis rov - zawm lawv tsis tu ncua. Nyob rau hauv ib puag ncig sab nraum zoov lossis kev txhim kho flange, yuav tsum kho nrog ove {4}
5. Kev Ua Haujlwm thiab Txij Nkawm Cov Lus Qhia
Thaum lub sijhawm kuaj xyuas, kuaj xyuas cov dej xau thiab xoob xoob thiab xoob hauv qab pob qij txha, thiab sau cov kev ua haujlwm tsis sib xws. Zam kev ua phem rau thaum lub sij hawm disassembly los tiv thaiv kev deformation flatation. Khaws rau hauv qhov chaw qhuav thiab cua kom tsis txhob muaj xeb.
Ua raws li cov kev ceevfaj no yuav ua kom zoo ua kom muaj kev nyab xeeb thiab ruaj khov ntawm ceg tawv nqaij thiab ua haujlwm ruaj khov ntawm cov kav dej.
