Tam sim no, ntau lub Hoobkas tau koom nrog cov khoom siv rov ua dua tshiab thiab kho tshiab ntawm lawv cov kev cob qhia, thiab kev txhim kho cov cuab yeej thev naus laus zis. Thiab, tau kawg, muaj kev hloov dav dav ntawm phau ntawv arc vuam tshuab nrog cov tshuab uas ua tsis siv neeg vuam. Cov khoom siv rov ua dua no tso cai rau cov khoom lag luam nce ntxiv, thiab tseem muab sijhawm txaus rau kev kho dua tshiab ntawm cov khoom siv los ntawm cov txheej txheem kev lag luam hauv cov khoom lag luam. Tsis siv neeg submerged arc vuam feem ntau yog siv. Qhov no tso cai rau hardfacing ntawm qhov chaw, uas yog suav hais tias yog ib tug nqi-zoo tshuaj uas ua rau kom cov khoom tsim tau, thiab kuj txhim kho qhov zoo ntawm weld.
Yog tias tsis siv neeg vuam ntawm qhov chaw yog nqa tawm hauv qhov qhib cua, txawm li cas los xij, qhov no, cov dej ntws tau tso rau ntawm qhov tshwm sim, ces lawv hais tias lub arc hlawv hauv qhov chaw kaw. Qhov tshwm sim no tau piav qhia los ntawm qhov tseeb tias cov txheej txheem flux yog ib hom electrode txheej, uas txhais tau hais tias nws ua haujlwm los tiv thaiv qhov chaw vuam los ntawm cov teeb meem ntawm huab cua puag ncig. Tsis tas li ntawd, flux surfacing yog siv los tiv thaiv kev tawghlau molten.
Tsis siv neeg submerged arc vuam ib txwm siv nrog cov hlau tsis muaj hluav taws xob. Txoj kev no tshem tawm ib qho tseem ceeb ntawm qhov tsis txaus nyob hauv hluav taws xob arc vuam. Nyob rau tib lub sijhawm, cov hlau ntawm cov khoom yuav tsum tau welded ua ntau yam, uas txhim kho qhov zoo thiab qhov ntom ntawm cov vuam.
Yog tias koj ua tib zoo xav txog cov txheej txheem ntawm kev nkag mus ntawm qhov vuam tam sim no los ntawm cov khoom yuav tsum tau welded, koj yuav pom tias cov arc hlawv hauv qhov sib txawv me me ntawm cov hlau electrode thiab qhov yuav tsum tau welded. Ntawm chav kawm, nws yuav tsum tau muab sau tseg tias cov hlau no yog pub los ntawm ib tug spool, uas unwinds cia li thiab yog pub rau hauv lub vuam cheeb tsam li lub vuam kawg melts. Rau cov xwm txheej no, siv lub tshuab tshwj xeeb tsim rau hauv lub tshuab vuam. Yog li, qhov ntws ntawm flux los ntawm ib lub thawv me me - lub bunker. Ib feem me me ntawm nws yog yaj nyob rau hauv kev cuam tshuam ntawm hluav taws xob arc. Txawm li cas los xij, thaum lub vuam tau txias thiab khov kho, yav tas los melted flux tau yooj yim tshem tawm. Tsis siv rov qab mus rau hauv lub hopper kab noj hniav thiab yog siv nyob rau hauv cov txheej txheem welding tom ntej.
Tsis siv neeg vuam cuam tshuam nrog ntau txoj hauv kev los txhim kho nws qhov kev ua tau zoo.
1. Nce hauv vuam tam sim no. Nws yog siv los ua kom qhov tob ntawm vuam, qhov thiaj li hu ua qhov tob tob ntawm cov hlau. Hauv qhov no, nws yog ib qho tseem ceeb uas qhov dav ntawm qhov vuam xyaum tsis hloov.
2. Qhov loj ntawm qhov hla ntawm cov electrode. Qhov no, ntawm qhov tsis sib xws, ua rau muaj qhov nce hauv qhov dav thiab txo qis hauv qhov tob ntawm qhov vuam. Nyob rau hauv lem, thim rov qab transformations, i.e. txo ntawm cov hlau seem, entail sib sib zog nqus vuam thiab txo qhov dav ntawm weld.
3. Cov kev tshawb fawb tau pom tias txawm tias muaj qhov nce me ntsis ntawm qhov arc ua ntej, qhov siab ntawm cov hlaws hlau tso rau hauv qhov siab nce ntxiv, thaum qhov tob tob thiab qhov dav ntawm qhov vuam txo qis.
Yog li, nws tuaj yeem hais tau tias tsis siv neeg vuam yog qhov zoo tshaj plaws rau kev siv hluav taws xob vuam.
