Membrane phab ntsa, tseem hu ua membrane dej-txias phab ntsa, siv cov hlab thiab cov hlau tiaj tus welded los tsim ib lub raj tshuaj ntsuam, thiab tom qab ntawd ntau pab pawg ntawm cov ntxaij vab tshaus cov ntxaij vab tshaus tau sib xyaw ua ke los tsim cov phab ntsa membrane.
Dab tsi yog qhov zoo ntawm cov phab ntsa membrane?
Lub membrane dej-txias phab ntsa ua kom zoo nruj ntawm lub qhov cub. Rau qhov tsis zoo siab boilers, nws muaj peev xwm txo tau cov cua to coefficient ntawm lub cub tawg, txhim kho cov combustion tej yam kev mob nyob rau hauv lub cub tawg, thiab ua rau kom lub zoo hluav taws xob cua sov cheeb tsam, yog li txuag steel noj. Membrane phab ntsa feem ntau yog siv nyob rau hauv daim nyias nyias phab ntsa chav generators. Lawv muaj qhov zoo ntawm cov qauv yooj yim, txuag steel, zoo dua rwb thaiv tsev thiab huab cua nruj.
Membrane phab ntsa raj tshuaj ntsuam melting tsis tshua muaj zog roj shielded tsis siv neeg vuam ntau lawm kab yog lub ntiaj teb no siab tshaj membrane phab ntsa raj screen manufacturing tshuab thiab khoom siv, los ntawm raj loading, ca steel uncoiling, xov, leveling, vuam, thiab lwm yam. Paub tsis siv neeg tswj. Cov phom welding sab saud thiab qis tuaj yeem welded tib lub sijhawm, qhov vuam deformation me me, thiab yuav luag tsis tas yuav tsum tau kho tom qab vuam, kom lub qhov ntev geometric ntawm lub raj vaj huam sib luag yog qhov tseeb, cov khoom siv vuam zoo zoo heev, cov duab zoo nkauj, vuam ceev yog ceev, thiab ntau lawm efficiency siab.
Nobeth chav generator muaj cov kab ntau lawm phab ntsa, thiab lub tshuab ua kom sov siv cov txheej txheem dej-txias phab ntsa sealing tshuab. Nyob rau hauv cov txheej txheem ntawm cov txheej txheem ntawm cov phab ntsa membrane, ob-sided ib txhij welding yog siv, kom lub workpiece yog rhuab ntau tusyees thiab lub raj vaj huam sib luag yog tsawg deformed; nws kuj tshem tawm qhov yuav tsum tau tig dua rau vuam, txo qhov kev ua haujlwm ntawm kev kho deformation tom qab vuam ntawm cov khoom, thiab txhim kho kev ua haujlwm zoo heev. Yog li ntawd, feem ntau cov membrane phab ntsa chav generators raug xa tawm tag nrho los ntawm lub Hoobkas, ua rau kev thauj mus los thiab kev teeb tsa yooj yim heev, thiab tus nqi ntawm kev teeb tsa ntawm qhov chaw xav tau los ntawm tus neeg siv tau txo qis heev.
(1) Cov phab ntsa membrane dej-txias muaj kev tiv thaiv zoo tshaj plaws ntawm phab ntsa rauv. Yog li ntawd, cov phab ntsa ntawm lub cub tawg tsuas xav tau cov ntaub ntawv rwb thaiv tsev es tsis txhob siv cov ntaub ntawv refractory, uas txo qhov tuab thiab qhov hnyav ntawm lub qhov cub phab ntsa, ua kom yooj yim rau cov phab ntsa ntawm lub cub tawg, thiab txo cov nqi ntawm cov phab ntsa ntawm lub cub tawg. Tag nrho boiler nyhav.
(2) Cov phab ntsa membrane dej-txias kuj muaj huab cua zoo nruj, tuaj yeem hloov kho raws li qhov yuav tsum tau muaj qhov zoo ntawm kev sib tsoo ntawm lub boiler, tsis yooj yim rau slagging, tsis muaj cua to, txo cov cua kub poob, thiab txhim kho cov thermal efficiency. lub boiler.
(3) Cov khoom siv tuaj yeem txuas tau los ntawm cov chaw tsim khoom ua ntej tawm hauv lub Hoobkas, thiab kev teeb tsa tau nrawm thiab yooj yim.
(4) Boilers siv cov phab ntsa membrane yog ib qho yooj yim thiab yooj yim los tswj, thiab kev pab cuam lub neej ntawm boiler tuaj yeem txhim kho zoo heev.
Vuam ntawm cov yeeb nkab vaj huam sib luag fillet welds
Tube screen welding txoj kev ntawm daim nyias nyias phab ntsa teeb yeeb nkab thiab tiaj steel qauv. Cov txheej txheem vuam siv nyob rau hauv daim nyias nyias phab ntsa lub teeb yeeb nkab thiab lub tiaj tiaj steel qauv feem ntau suav nrog cov hauv qab no:
1. Tsis siv neeg melting tsis tshua muaj zog roj shielded vuam
Cov sib xyaw ua ke ntawm cov roj tiv thaiv yog (Ar) 85% ~ 90% + (CO2) 15% ~ 10%. Nyob rau hauv cov khoom siv, cov yeeb nkab thiab cov hlau tiaj tiaj yog nias los ntawm cov yob sab sauv thiab qis thiab thauj mus rau pem hauv ntej. Ntau cov phom vuam siv tau los txav mus los. Vuam yog ua ib txhij.
2. Fine hlau submerged arc vuam
Cov cuab yeej no yog ib qho ruaj khov welding workstation. Cov cuab yeej siv lub tshuab muaj cov haujlwm ntawm cov yeeb nkab steel thiab tiaj tus hlau qhov chaw, clamping, pub, vuam thiab tsis siv neeg flux rov qab. Nws yog feem ntau nruab nrog 4 lossis 8 vuam phom kom tiav 4 lossis 8 txoj haujlwm kab rov tav tib lub sijhawm. Vuam ntawm fillet welds. Cov tshuab no yooj yim rau kev khiav lag luam thiab tsis muaj cov kev xav tau siab ntawm cov yeeb nkab thiab cov hlau tiaj tus. Txawm li cas los xij, nws tsuas tuaj yeem welded ntawm ib sab hauv txoj haujlwm kab rov tav thiab tsis tuaj yeem ua tiav ib txhij vuam ntawm sab saum toj thiab hauv qab.
3. Semi-automatic gas hlau arc vuam
Thaum vuam los ntawm txoj kev no, lub raj vaj huam sib luag yuav tsum tau tack-welded thiab ruaj ua ntej, thiab tom qab ntawd welded los ntawm kev ua haujlwm ntawm rab phom vuam. Txoj kev vuam no tsis tuaj yeem welding lub sab sauv thiab sab hauv tib lub sijhawm, thiab nws yog ib qho nyuaj rau kev ua tiav cov vuam txuas txuas thiab tsis sib xws ntawm ntau cov phom vuam, yog li nws nyuaj rau tswj cov vuam deformation. Thaum semi-automatic gas hlau arc vuam siv rau cov yeeb nkab vaj huam sib luag welding, yuav tsum tau them nyiaj rau qhov tsim nyog xaiv ntawm vuam ib ntus kom txo vuam deformation. Lub fillet welds rau sealing ca hlau nyob rau hauv lub zos qhib ntawm lub raj panels, raws li zoo raws li cov fillet welds rau tshwj xeeb-shaped raj panels xws li txias tshauv hoppers thiab burner nozzles, feem ntau welded los ntawm semi-automatic gas hlau arc vuam.
Membrane phab ntsa raj tshuaj ntsuam melting tsis tshua muaj zog roj shielded tsis siv neeg vuam ntau lawm kab yog lub ntiaj teb no siab tshaj membrane phab ntsa raj screen manufacturing tshuab thiab khoom siv, los ntawm raj loading, ca steel uncoiling, xov, leveling, vuam, thiab lwm yam. Paub tsis siv neeg tswj. Cov phom welding sab saud thiab qis tuaj yeem welded tib lub sijhawm, qhov vuam deformation me me, thiab yuav luag tsis tas yuav tsum tau kho tom qab vuam, kom lub qhov ntev geometric ntawm lub raj vaj huam sib luag yog qhov tseeb, cov khoom siv vuam zoo zoo heev, cov duab zoo nkauj, vuam ceev yog ceev, thiab ntau lawm efficiency siab.
