Kev haus luam yeeb muaj pes tsawg leeg thiab cov yam ntxwv
Welding cov pa roj carbon monoxide yog ua los ntawm oxidation thiab hws ntawm vapors generated los ntawm cov hlau thiab cov khoom tsis muaj xim nyob rau hauv tej yam kev mob loj. Yog li ntawd, cov khoom siv tshuaj ntawm lub vuam fwj yog nyob ntawm cov khoom siv (vuam hlau, welding pas nrig, flux, thiab lwm yam.) Thiab cov lus sau ntawm cov khoom yuav tsum tau welded thiab nws evaporating nyuaj. Vuam cov khoom sib txawv ntawm cov khoom sib txawv thiab cov khoom siv los ua welded yuav tsim ntau cov khoom sib txuas ntawm cov vuam fwj thaum lub vuam siv.
Cov yam ntxwv ntawm vuam pa taws yog:
(1) Lub plua plua plav yog qhov me me, cov hmoov av yog nyob rau hauv daim ntawv ntawm cov khoom tawg, thiab qhov loj me me li ntawm 1 μm.
(2) Vuam cov pa taws ua pa heev.
(3) Qhov kub ntawm vuam cov pa yog qhov siab. Nyob rau hauv cov pa roj carbon monoxide thiab lim caij, cua kub yog 60 ~ 80 ° C.
(4) Tus nqi ntawm cov plua tshauv thaum lub vuam txheej txheem yog loj. Feem ntau, tus nqi ntawm cov khoom ua tau ua los ntawm ib qhov chaw ua haujlwm 1d yog txog 60 ~ 150g. Ob qho vuam siv (txiav), ntau npaum li cas plua plav ib feeb thaum welding (thaum txiav) thiab ntau npaum li cas hmoov av ib kilogram ntawm vuam khoom
Plua plav tus nqi ntawm txoj hlua
Cov tshuaj carbon dioxide welding
Khoom hlau (inch 1.6mm) 450 ~ 650 5 ~ 8
Flux cored hlau (inch 1.6mm) 700 ~ 900 7 ~ 10
Cov pa roj carbon dioxide ua kom muaj pa taws ntau
Cov pa phem nyob rau hauv CO2 roj thaiv cov hlua ntawm qhov vuam tsoo raug faib ua ob pawg: tshuaj lom neeg muaj kuab lom thiab lub cev muaj kuab paug.
tshuaj lom neeg lom neeg
Tshuaj lom neeg ua paug tuaj yeem hais txog cov pa roj carbon monoxide poov xab thiab cov khoom tsim tawm thaum CO2 roj thaiv cov hlua. Thaum ua CO2 roj thaiv cov hlua, qee qhov teeb meem cov khoom tsim muaj nyob rau ntawm kab hauv qhov chaw vuam.
Cov tshuaj phem tsim tawm los ntawm CO2 roj shield welding yuav muab faib ua ob pawg, ib qho yog cov teeb meem roj, carbon dioxide (CO2), carbon monoxide (CO), nitrogen dioxide (NO2) thiab ozone (O3). Ib hom yog lub pob zeb, thiab nws lub ntsiab ntawm lub cev yog cov oxide (Fe2O3), silicon dioxide (SiO2), thiab manganese oxide (MnO). Cov teeb meem no, tshwj tsis yog carbon dioxide, yog siv los tiv thaiv lub arc thiab lub pas dej ua ke. Lub welding yog nqa tawm ntawm lub vuam tsoo. Lub vuam yog tsis siv thiab nyob ib ncig ntawm qhov chaw welding. Cov khoom seem uas yog tsim los ntawm lub vuam arc thiab lub pas dej ua ke.
Lub cev tsis huv
Lub cev muaj paug muaj xws li: ultraviolet light thiab infrared rays generated los ntawm high-temperature arc lub teeb ntawm CO2 roj shielded welding.
Cov pa roj carbon dioxide ua kom siv pa tawm
ntuj qhov cua
Cartridge ntaus mobile welding pa taws.
Kev siab tsis zoo siab vuam pa plua plav collector
Qhov txiaj ntsig ntawm lub cev yog qhov qis tshaj plaws, tsuas yog siv cov kev ntshiab li qub, txo cov ntsiab lus ntawm cov vuam tsom rau hauv qhov kev kawm uas qhib qhov rais thiab qhov cua.
Filter cartridge type mobile welding pa luam yeeb purifier, aiming universal xuas caj npab ntawm qhov chaw uas cov pa taws ua pa taws. Cov plua tshauv thiab cov pa roj carbon monoxide yog tsim los ntawm cov pa roj carbon dioxide hauv cov vuam tsom ntim rau hauv lub tshuab fais fab. Cartridge mobile vuam fume purifiers muaj ntau hom kev siv. Nws yog qhov yooj yim thiab yooj ywm thiab yooj yim txav. Muaj peev xwm ua tau raws li ntau txoj haujlwm ua haujlwm zoo.
Qhov siab tsis zoo siab vuam fume extractor mas txuas lub 50 hli inch hose ncaj qha mus rau lub taub hau taub hau. Thaum lub chaw ua haujlwm ua haujlwm, cov hmoov av ua haujlwm ua haujlwm, thiab cov hmoov av plua plav nres thaum tus welder nres. Qhov no saib xyuas zoo ntawm kev siv vuam cov pa taws thaum siv cua ntim tsawg kawg nkaus. Tsis tas li ntawd, qhov vuam fume precipitator tau txuas nrog lub hose txog li 20m, uas tuaj yeem raug txuas mus rau lub taub hau vuam tsis siv neeg. Tshaj kom tsis muaj txhij txhua ntawm phau ntawv xuas phom xuas tes xuas tes tshem tawm ntawm txoj haujlwm. Nws tab tom ua kom zoo nkauj, thiab cov khoom nyhav thiab kev huv huv yog qhov zoo tshaj plaws.
