A umsiki we-plasma iyithuluzi elisika insimbi lisebenzisa igesi elishiselwa emazingeni okushisa aphezulu kakhulu futhi eline-ionized kakhulu. Idlulisela amandla e-arc kucezu lokusebenza. Izinga lokushisa eliphakeme lincibilikisa i-workpiece futhi liyiphephule, lenze isimo sokusebenza sokusika kwe-plasma. Khona-ke, insimbi iyancibilika kusetshenziswa i-plasma arc njengomthombo wokushisa.
Ukusika kwe-Plasma kubhekisela ekukhishweni kwegesi engasebenzi ngesivinini esiphezulu noma igesi ecindezelwe esuka kubhobho ukuze kwakhe i-plasma, encibilikisa insimbi ukuze isikwe. Ngenxa yokuthi i-plasma ayizikhiqizi izinsimbi njengamalangabi, imishini yokusika i-plasma ingasika izinsimbi ezihlukahlukene okunzima ukuzisika ngomoya kanye namagesi asebenzayo ahlukene.

Ikhwalithi Engcono Yokusika
Amalahle, indawo ethinteke ukushisa, i-top edge fillet, kanye ne-engeli yokusika yizinto ezimbalwa ezinkulu ezithinta ikhwalithi yokusika. Ikakhulukazi ezicini ezi-2 ze-scum kanye nendawo ethinteke ukushisa, ukusika kwe-plasma kuphakeme kakhulu kunokusika ilangabi. Ngokuyisisekelo akukho scum osele onqenqemeni lokusikwa kwe-plasma, futhi indawo ethinteke ukushisa incane kakhulu.
Umkhuhlane
Inqubo ye-plasma isebenzisa igesi eshisayo, eshajwa ngogesi ukuze incibilikise insimbi futhi ivuthele insimbi encibilikisiwe isuke endaweni esikiwe. Ukusika ilangabi kusebenzisa ukusabela kwamakhemikhali phakathi komoyampilo nensimbi ukusika, ngaleyo ndlela kukhiqiza insimbi ebomvu ye-slag noma i-scum. Ngenxa yalomehluko wenqubo, ukusikwa kwe-plasma kukhiqiza amanyela amancane, futhi amanyela anamathela kuwo kulula ukuwakhipha. Lo doti ungasuswa kalula ngaphandle kokusahlabathi noma ukufosholo, kunciphisa kakhulu isikhathi esidingekayo ekusebenzeni kwesibili, okuholela ekukhiqizeni okuphezulu ngokusebenza kokusahlabathi okumbalwa.
Ukusebenza Okuphezulu
Ngaphezu kwesikhathi esilondolozwe ekushiseni kwangaphambili nasekucutshungulweni kwesibili, ijubane lokusika nokubhoboza le-CNC plasma lingafinyelela izikhathi ezifika ku-8.5 zokusika ilangabi, futhi ukwanda okukhulu kokusebenza kahle kokukhiqiza kungaletha izinzuzo ezinkulu.
Izindleko Eziphansi
Lapho uhlaziya izindleko, kubalulekile ukuqonda umehluko phakathi kwezindleko zokusebenza nezindleko zokusebenza ngengxenye ngayinye noma imitha. Ngakho-ke unquma kanjani izindleko zangempela zokusika ingxenye? Izindleko zokugijima imitha ngayinye yizindleko zakho konke ukusika ngehora kuhlukaniswe ubude obuphelele (amamitha) obungasikwa ngehora elilodwa. Izindleko ezihilelekile ekusikeni zihlanganisa izinto ezisetshenziswayo, ugesi, igesi, abasebenzi kanye ne-overhead eqhubekayo. Izindleko ngengxenye yingqikithi yobude bokusika obudingekayo ukuze kukhiqizwe ingxenye yezindleko zokugijima imitha ngayinye. Amasistimu e-plasma anqamula ngokushesha futhi akhiqize izingxenye ezengeziwe esikhathini esithile, okuholela ezindlekweni eziphansi kakhulu ngokusikwa kwengxenye ngayinye. Ngokusika okubanjwa ngesandla, ukubala izindleko zomsebenzi ngamunye noma umsebenzi kunikeza isilinganiso esingcono sokonga. Izindleko zehora eziphindwe ngenani eliphelele elidingekayo ukuze kuqedwe umsebenzi zilingana nezindleko zomsebenzi. Ukusika i-oxyfuel, kubalulekile ukufaka isikhathi sokushisa ngaphambi kwesikhathi kanye nesikhathi eside sokucubungula sesibili sibe yisikhathi esidingekayo.
Inzuzo Ephakeme
Izindleko eziphansi ngengxenye ngayinye yohlelo lwe-plasma zihumusha ngokuqondile ekwenzeni inzuzo ethuthukisiwe. Ukusika ingxenye ngayinye konga imali, okwandisa izilinganiso zenzuzo. Uma usika izingxenye eziningi ngehora, uzokwandisa inzuzo yakho yonke.
Kulula Ukusebenzisa
Kubasebenzisi be-oxyfuel, kuthatha isikhathi ukufunda nokuzijwayeza ukukwazi ukusetha imingcele yekhemistri yomlilo kanye nokugcina ikhemistri yomlilo. Kodwa-ke, uhlelo lokusika i-plasma kulula ukulufunda futhi luyingcweti, futhi lunokuzinza okuphezulu nokusebenza okulula ngesikhathi sokusika izingcezu zomsebenzi. Okuhlangenwe nakho okuningi okubalulekile okusendaweni kuhlanganiswe nomsebenzi wenqubo yokulawula ukusika, ophelele ekusebenzeni futhi kulula ukuyisebenzisa.
Ukuguquguquka Okuphakeme
Izinhlelo ze-Plasma zingasika noma iyiphi insimbi eqhubayo, okuhlanganisa insimbi engagqwali, i-aluminium, ithusi nethusi. Imishini yokusika amalangabi isebenzisa ukusabela kwamakhemikhali phakathi kwe-oxygen ne-iron ensimbi enekhabhoni ephansi ukusika, ngakho-ke ingasetshenziswa kuphela ukusika insimbi ephansi (ikhabhoni). Ngaphezu kwalokho, izinhlelo ze-plasma zingasetshenziselwa ukugoba, ukumaka noma ukusika insimbi egqwalile, ependiwe noma enqwabelene. Akukhona lokho kuphela, kodwa ungakwazi futhi ukugoba noma ukusika insimbi eyandisiwe ngesistimu ye-plasma, okunzima ukuyenza nge-oxyfuel.
Ukuphepha Okuphakeme
Uphethiloli osetshenziswa ekunqumeni ilangabi ingxube ye-oxygen negesi. Amagesi kaphethiloli asetshenziswa kakhulu yi-acetylene, propane, MAPP, propylene kanye negesi yemvelo. Okuvame ukusetshenziswa kakhulu kulezi yi-acetylene ngoba ikhiqiza izinga lokushisa eliphezulu lelangabi kanye nokubhoboza ngokushesha kunamanye amagesi. Kodwa-ke, i-acetylene iyigesi engazinzile futhi evutha kakhulu ezwela kakhulu engcindezini eyeqile, izinga lokushisa, ngisho nogesi omile. Ukuqhuma kwe-acetylene kungabangela izinkulungwane zamadola emonakalweni wempahla kanye nokulimala kanzima kubantu abaseduze. Amanye amasistimu e-plasma ngokuvamile asebenza emoyeni ocindezelwe futhi awadingi ukusetshenziswa kwamagesi avuthayo.
Zonke izinhlobo zokusika ezishisayo zizokhiqiza iphunga elithile nomsindo, njengokusika okushisayo usebenzisa itafula lokusika kanye nomshini we-CNC plasma cutting machine system ungakhetha umbhede wokusika amanzi, onganciphisa kakhulu iphunga nomsindo. Ukusika amalangabi amaningi akufanele kwenziwe ngaphansi kwamanzi ngenxa yengozi yokuqhuma.
bawo
Kodwa akukho mishini engenasici, futhi umshini wokusika i-plasma usathuthukiswa, futhi nawo unokushoda. Ngenxa yokuthi ukukhanya kwayo kwe-arc kunamandla kakhulu, inokungcola okuthile. Ngaphezu kwalokho, umsindo owenziwe ngesikhathi sokucubungula ukhulu kakhulu, futhi kusenothuli oluningi, ngakho-ke lokhu akulungile kakhulu ekuvikelweni kwemvelo. Kufanele kushiwo ukuthi izinkinga ezihlobene nokuvikelwa kwemvelo zinkulu kakhulu. Manje njengoba okokusebenza kuthuthukiswa kancane kancane, silindele futhi ukuthi kube nokubukeka okusha nokuphelele.
• Ukusika kwe-Plasma kuzokhiqiza igesi eyingozi kanye ne-arc: Umgomo wokusika i-plasma unquma ukuqina kwe-arc, umsindo nothuli phakathi nenqubo yokusika, okuzongcolisa imvelo ngezinga elithile. Ukusika i-plasma engaphansi kwamanzi kuvame ukusetshenziselwa amapuleti aphakathi nendawo nawugqinsi, ngakho-ke ubukhulu bokusika bukhawulelwe.
• Ukuphakama kwendawo yokusika akulungile: uhlangothi olulodwa lwendawo yokusika luzoba ne-bevel enkulu, futhi ukuphakama kumpofu.
• Ngesikhathi sokusika, i-slag eyengeziwe yokusika ikhiqizwa ebusweni benqubo yokusika. Njengoba ikhwalithi yenqubo ingathinteki, i-slag ngemva kokusika kufanele ibe phansi, okwandisa nezindleko zabasebenzi.
• Ukusika i-Plasma kunendawo enkulu ethinteke ekushiseni kanye ne-kerf ebanzi. Ayifanele ukusika amashidi amancane njengoba ishidi lizokhubazeka ngenxa yokushisa.
• Izinto ezisetshenziswayo njengemimese zidliwa ngokushesha. Manje imibhobho yokusika incike kakhulu ekuthengeni kwamanye amazwe, futhi izindleko ziphakeme kakhulu.
