Makina odulira gasi ndi okwera kwambiri, olondola kwambiri komanso odalirika kwambiri opangira matenthedwe omwe amayendetsedwa ndi makompyuta, makina olondola komanso ukadaulo wamagetsi.
Ubwino wa makina odulira gasi ndi chiyani?
Momwe mungathanirane ndi zolakwika zomwe zimachitika pamakina odulira Gasi?
Kodi mfundo yogwirira ntchito ya makina odulira gasi ndi chiyani?
Ubwino wa makina odulira gasi ndi chiyani?
Makina odulira gasi ali ndi ubwino wolemera pang'ono, mphamvu zambiri, kukana kwa dzimbiri, kamangidwe kakang'ono, ntchito yabwino komanso kugwiritsa ntchito bwino. Makina odulira gasi amagwiritsa ntchito acetylene yapakatikati komanso mpweya wothamanga kwambiri pantchito yodula. Imatha kudula mbale zachitsulo ndi makulidwe opitilira 8 mm, makamaka kudula mzere wowongoka, komanso kudula kozungulira ndi mainchesi opitilira 200 mm, komanso kudula kwa bevel ndi V. Itha kugwiritsanso ntchito mphamvu ya makina odulira Gasi ndi zida zofananira zowonjezera kuti azimitsa moto ndi kuwotcherera pulasitiki. Kukula kwamphamvu kwa mbale yachitsulo yodulidwa kumatha kufika 12.5. Nthawi zambiri, palibe kudula pamwamba komwe kungachitike mutadula.
Momwe mungathanirane ndi zolakwika zomwe zimachitika pamakina odulira Gasi?
1. Kuwonongeka kwa nsonga yodulira ndi electrode: Ngati nsonga yodula ya makina odulira Gasi imayikidwa molakwika, osamangika, kapena tochi yodulira madzi yamadzi sikugwirizana ndi dongosolo lozizira, kutayika kwa nsonga yodula kudzawonjezeka.
Yankho: Sinthani zida zolondola za zida molingana ndi magawo ofunikira a chodulira chodulira, ndikuwona ngati nyali yodulira ndi bubu lodulira zidayikidwa mwamphamvu; tochi yodulira madzi yoziziritsidwa iyenera kuzungulira madzi ozizira pasadakhale.
2. Mpweya wolowetsa mpweya ndi wokwera kwambiri: ngati kulowetsedwa kwa mpweya wa makina odulira Gasi kuli kwakukulu kuposa 0.45MPa, kutuluka kwa mpweya ndi kupanikizika kwakukulu pambuyo pa kupangidwa kwa plasma arc kudzawomba chingwe cha arc, kufalitsa mphamvu ya ndime ya arc ndikufooketsa mphamvu yodulira ya plasma arc.
Yankho: Yang'anani ngati kusintha kwa mpweya wa compressor kwasinthidwa bwino, ndipo muwone ngati kupanikizika kwa mpweya wa compressor kumagwirizana ndi kupanikizika kwa valve yochepetsera mpweya. Sinthani kusintha kosinthira kwa valavu yochepetsera fyuluta ya mpweya pakugwira ntchito kwa compressor ya mpweya. Ngati choyezera kuthamanga kwa mpweya sichikusintha, zikutanthauza kuti valavu yochepetsera fyuluta ya mpweya ili kunja kwa dongosolo ndipo iyenera kusinthidwa panthawi yake.
Kodi mfundo yogwirira ntchito ya makina odulira gasi ndi chiyani?
Kudula kwamafuta olekanitsa lawi lopangidwa ndi kuyaka kosakanikirana kwa mpweya woyaka ndi mpweya, womwe umadziwikanso kuti kudula kwa okosijeni kapena kudula lawi. Panthawi yodula gasi, lawi lamoto limatenthetsa zinthuzo mpaka poyatsira pamalo odulira, kenako amabaya mpweya wa okosijeni kuti zinthu zachitsulo ziwotche mwamphamvu ndikuwotcha, ndipo chitsulo chopangidwa ndi oxide chimawombedwa ndi mpweya kuti apange kudula. Kuyera kwa okosijeni komwe kumagwiritsidwa ntchito pamakina odulira Gasi kuyenera kukhala kwakukulu kuposa 99%; mpweya woyaka nthawi zambiri umagwiritsa ntchito mpweya wa acetylene, komanso amatha kugwiritsa ntchito mafuta amafuta, gasi wachilengedwe kapena malasha. Kudula bwino ndi mpweya wa acetylene ndipamwamba kwambiri, khalidwe ndilabwino, koma mtengo wake ndi wapamwamba.
