Umshini wokusika i-Plasmaisebenzisa ukugeleza komoya okunesivinini esikhulu okhishwe ku-nozzle ukuze i-ionize yakhe i-conductor kagesi.Lapho i-current idlula, umqhubi wenza i-arc ye-plasma ephezulu yokushisa.Ukushisa kwe-arc kuncibilikisa kancane insimbi ekusikeni kwendawo yokusebenza.Inqubo lapho kukhishwa khona insimbi encibilikisiwe ukuze kwakheke isikwele.I-arc encane futhi ezinzile ye-plasma eyakhiwe ubuchwepheshe bokugeleza kwegesi ye-annular ingaqinisekisa ukusika okubushelelezi nokonga kwanoma iyiphi insimbi eqhubayo.Kulula ukuyiqonda ngemva kokwazi isimiso sokusebenza somshini wokusika we-plasma onamandla aphezulu bese ufunda izinyathelo zokuphepha zokusebenza.
Okokuqala, nquma kusukela onqenqemeni, ungabhobozi ukusikwa.Khomba umbhobho ngokuqondile emaphethelweni ocezu lokusebenza ngaphambi kokuqala i-arc ye-plasma, usebenzisa unqenqema njengendawo yokuqala yokwelula impilo yezinto ezisebenzisekayo.I-nozzle kanye ne-electrode kusetshenziswa ngokushesha okukhulu lapho uqala i-arc, ngakho-ke qiniseka ukuthi ubeka ithoshi ngaphakathi kwebanga lokuhamba lensimbi yokusika ngaphambi kokuqala ukunciphisa isikhathi sokuqala se-arc esingadingekile.
Okwesibili, ungalayishi kakhulu umlomo wombhobho.Uma umthwalo weqiwe, i-nozzle cishe izolimala.Ngokuvamile, umfutho wamanje ungama-95% wamanje osebenzayo wombhobho.Ibanga phakathi kwe-nozzle yokusika kanye nobuso be-workpiece kufanele ibe nengqondo.Ngokuvamile, kufaneleka kakhulu ukusebenzisa kabili ibanga elivamile lokusika, noma ukuphakama okuphezulu okungadluliswa yi-plasma arc.
Ubukhulu be-perforation kufanele bube phakathi kwebanga elishiwo umshini wokusika we-plasma wamandla aphezulu.Uma idlula ubukhulu bokusika obucacisiwe, umphumela wokusika oyifunayo awukwazi ukufezwa.Imvamisa, ukujiya kwembobo kungu-1/2 wogqinsi olujwayelekile lokusika.Lapho ushintsha izingxenye ezisebenzisekayo, hlanza uthuli nokungcola okungaphezulu ukuze ugcine ingaphezulu lezingxenye ezisebenzisekayo lihlanzekile.Futhi hlola intambo yokuxhuma yethoshi njalo, bese uhlanza indawo ethinta i-electrode kanye nombhobho ngesihlanzi esisekelwe kwi-hydrogen peroxide.
Ukusebenza okulungile kuphela komshini wokusika i-plasma wamandla aphezulu kungaqinisekisa ukusebenza okuvamile kwemishini kanye nomsebenzi ophezulu kanye nokusebenza kahle.Esigabeni esilandelayo, umhleli uzokwethula ubuhlobo phakathi kwejubane lokusika kanye nekhwalithi yokusika yemishini yokusika i-plasma enamandla amakhulu.Siyakwamukela esigabeni sezindaba sewebhusayithi yethu esemthethweni ukuze ufunde kabanzi mayelana nemishini yokusika!
