Stainless hlau bellows muaj kev xav tau siab heev rau vuam. If lub vuam tshuab tsis paub tab, nws yuav ua rau muaj teeb meem xws li perforation, dej leakab thiab xeb ntawm lub tshuab. Muaj coob tus neeg tsis paub yuav ua li cas stainless hlau bellows yog welded. Hnub no peb yuav piav qhia rau koj.
Stainless hlau bellows vuam tshuab yog muab faib ua TIG vuam (tsis yog-melting polar gas tungsten shielded vuam) thiab MIG vuam (melting polar gas shielded vuam). Qhov sib txawv ntawm ob qhov lus dag hauv cov khoom siv hauv cov txheej txheem vuam. MIG siv Hlau, thaum TIG siv tungsten electrodes nyob rau hauv lub teeb, lwm yam tshaj li, tsis muaj ntau qhov sib txawv ntawm ob.
TIG welding: TIG vuam muaj cua nruj dua. Qhov chaw tshav kub yog DC arc, qhov ua haujlwm voltage yog 10-95 volts, thiab tam sim no tuaj yeem ncav cuag 600 amps. Nws feem ntau yog siv rau nruab nrab-tuab ua haujlwm.
MIG welding: arc vuam txoj kev uas siv cov roj sab nraud ua qhov nruab nrab arc thiab tiv thaiv cov tee hlau thiab cov hlau kub kub hauv cheeb tsam vuam.
Stainless hlau vuam tuaj yeem muab faib ua tsib kauj ruam:
Thawj kauj ruam: Qhov loj ntawm cov yeeb nkab. Thaum vuam, koj yuav tsum ntsuas qhov ntev ntawm cov yeeb nkab ua ntej, thiab tom qab ntawd siv cov yeeb nkab cutter los txiav qhov loj ntawm cov yeeb nkab.
Cov kauj ruam thib ob: ntxuav cov kav dej. Txij li thaum lub raj xa dej yog cov khoom siv hlau, qee cov khoom pov tseg yuav raug tsim nyob rau hauv lub raj, thiab qee qhov pov tseg yuav cuam tshuam rau cov khoom siv vuam. Yog li ntawd, thaum peb siv daim ntaub emery los yog ntawv los zom cov khib nyiab pov tseg hauv cov yeeb nkab ua ntej vuam.
Kauj Ruam 3: Siv lub raj txhuam txhuam los ntxuav cov fittings. Ntxuav cov fittings tso cai rau lub vuam hose kom huv si thiab tinned sib koom.
Kauj Ruam 4: Ua lub sijhawm vuam. Feem ntau hais lus, ntev npaum li cas koj yuav tsum tau welding lub raj xa dej, koj xav tau qhov ntev ntawm solder.
Kauj Ruam 5: Siv lub teeb hluav taws xob kub. Lub teeb hluav taws xob cov yeeb nkab yog feem ntau los xyuas kom meej tias qhov vuam ntawm cov yeeb nkab yog sib npaug. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias thaum siv lub teeb ci, xyuas kom cov nplaim hluav taws nyob ze txaus los npog tag nrho txoj kab uas hla ntawm cov yeeb nkab.
Thaum lub raj sab hauv yog welded, qhov kub yuav tsum tsis txhob siab dhau. Yog tias nws siab dhau lawm, cov khoom yuav hloov thiab xeb yooj yim. Lub raj sab nrauv yuav tsum muaj qhov ntsuas cua txias thaum lub sijhawm vuam. Yog tias qhov kub thiab txias dhau lawm, lub raj sab hauv yuav raug cuam tshuam. Yog li ntawd, kev ntsuas cua zoo yog qhov tseem ceeb heev.
Ntxiv nrog rau cov cuab yeej siv vuam, cov roj sib xyaw kuj tseem yuav tsum tau ua qhov nruab nrab rau ob txoj kev vuam, nrog rau 90 feem pua argon ntxiv rau 20 feem pua carbon dioxide. Nws tuaj yeem pom tau tias qhov vuam ntawm stainless hlau bellows cia siab rau kev siv tshuab thiab kev saib xyuas.
Welded stainless steel bellows muab kev ua haujlwm siab cushioning thiab meej resilience piv rau conventionally tsim bellows, yog li lawv muaj peev xwm muab tau ntau dua resilience thiab tswj nyob rau hauv tsawg tshaj plaws ntawm qhov chaw. Ntug-welded stainless hlau bellows yog tsim los ntawm vuam sab hauv thiab sab nraud txoj kab uas hla, thiab vim lub ductility ntawm cov khoom, tus naj npawb thiab cov duab ntawm bellows convolutions rau cov tsoos forming yog txwv, yog li ntug-welded bellows tuaj yeem xaiv ntau yam khoom siv. .
