I-rotor ye-graphiteukukhishwa kwe-aluminium iyisisetshenziswa esibalulekile embonini yokuphonsa ingxubevange ye-aluminium, umsebenzi wayo uwukuhlanza ukuncibilika kwe-aluminium nokuthuthukisa ikhwalithi nokuzinza kwe-aluminium alloy casting. Lesi sihloko sizocubungula isimiso sokusebenza, izinzuzo, izici, kanye nezixazululo ezenziwe ngokwezifiso zama-graphite rotor zokuphonswa kwe-aluminium, ukuze kusizwe abantu abaningi baqonde ukubaluleka nezinkambu zokusetshenziswa zale divayisi engukhiye.
Umgomo wokusebenza: ukhiye wokuhlanza i-aluminium encibilikayo
Umsebenzi oyinhloko we-graphite rotor for aluminium casting ukujova i-nitrogen noma i-argon gas ku-aluminium encibilika ngokuzungeza, ukuphula igesi ibe inombolo enkulu yamabhamuza ahlakazekile futhi iwahlakaze ensimbi encibilikisiwe. Bese, i-graphite rotor isebenzisa ukucindezela kwegesi okuhlukile kwamabhamuza ekuncibilikeni kanye nomgomo wokukhanga komhlaba ukuze umunce igesi ye-hydrogen kanye ne-oxidation slag ekuncibilikeni. Lawa mabhamuza akhuphuka kancane kancane ngokujikeleza kwe-graphite rotor futhi asuse amagesi ayingozi nama-oxide adsorbed ebusweni bokuncibilika, ngaleyo ndlela abambe iqhaza ekuhlanzeni ukuncibilika. Ngenxa yokusabalalisa okuncane nokufana kwama-bubbles ekuncibilikeni, okuxubene ngokulinganayo nokuncibilika futhi kungakhi umoya oqhubekayo, igesi ye-hydrogen eyingozi ekuncibilikeni kwe-aluminium ingasuswa ngokuphumelelayo, ithuthukise kakhulu umphumela wokuhlanza.
Izinzuzo nezici ze-graphite rotor
Amarotha e-graphite okwenziwa kwe-aluminium anezinzuzo eziningi nezici ekubunjweni kwe-aluminium alloy, okuwenza athandwe kakhulu. Okokuqala, i-nozzle ejikelezayo ye-graphite rotor yenziwe nge-graphite ephakeme kakhulu enokwelashwa okukhethekile kwendawo, ngakho-ke impilo yayo yesevisi ngokuvamile iphindwe kathathu kunemikhiqizo evamile. Lokhu kusho ukuthi ama-graphite rotor angasebenza ngokuzinzile isikhathi eside, anciphise imvamisa yokushintsha kanye nezindleko zabasebenzi.
Okwesibili, ama-graphite rotor anganciphisa izindleko zokucubungula, ukusetshenziswa kwegesi engasebenzi, kanye nokuqukethwe kwe-aluminium ekuncibilikeni kwe-aluminium. Ngesikhathi senqubo yokukhipha nokuhlanza, ngesakhiwo se-nozzle esiklanywe ngokunengqondo, i-graphite rotor ingakwazi ukuhlakaza amabhamuza futhi iwaxube ngokulinganayo noketshezi lwe-aluminium alloy, ikhulise indawo yokuxhumana nesikhathi phakathi kwamabhamuza noketshezi lwe-aluminium alloy, ngaleyo ndlela ithuthukise ukukhishwa kwegesi. kanye nomphumela wokuhlanza.
Ngaphezu kwalokho, ijubane le-graphite rotor lingalawulwa ngokulawulwa kwesivinini sokuguqula imvamisa, ukufeza ukulungiswa okungenasinyathelo, ngenani eliphakeme lika-700 r/min. Lokhu kunikeza lula ukusebenza nokulawula phakathi nenqubo yokukhiqiza, okwenza izinga lokususa umoya lifinyelele ngaphezu kwama-50%, kuphinde kufinyeze isikhathi sokuncibilikisa futhi kwehlise nezindleko zokukhiqiza.
Isixazululo ngokwezifiso: ukuhlangabezana nezidingo ezahlukene
Ngokuklanywa nokuhleleka kwama-graphite rotor okwenziwa kwe-aluminium, ngenxa yemininingwane ehlukene yama-graphite rotor asetshenziswa emigqeni ehlukene yokukhiqiza, ukuhlaziya lobuchwepheshe kudingeka kwenziwe ngokusekelwe emidwebeni yokuqala yokuklama ehlinzekwe yikhasimende kanye nohlu lwemibuzo lwendawo yokusetshenziswa kwesayithi. wama-graphite rotor agcwaliswe. Phakamisa uhlelo olufanelekile lokwelapha ukuguguleka okusekelwe ezintweni ezifana nesivinini sokuzungeza, isiqondiso sokuzungeza, nendawo ehlobene nendawo ewuketshezi ye-aluminium ye-graphite rotor. I-nozzle ejikelezayo ye-graphite rotor yenziwe nge-high-purity graphite, futhi isakhiwo sayo asibheki nje kuphela umsebenzi wamabhamuza ahlakazayo, kodwa futhi sisebenzisa ngokugcwele amandla ase-centrifugal akhiqizwa ngokushukumisa i-aluminium alloy alloy ukuze enze ukuncibilika kungene emlonyeni futhi ngokulinganayo. xuba negesi efuthwe ngokuvundlile, wenze ukugeleza kwegesi-uketshezi bese ufafaza ngaphandle, ukhulise indawo yokuxhumana kanye nesikhathi sokuxhumana phakathi kwamabhamuza kanye noketshezi lwe-aluminium alloy, ngaleyo ndlela kuthuthukiswe umphumela wokuqeda nokuhlanza.
I-graphite rotor inezinhlobo eziningi zokucaciswa futhi ifanelekileΦ 70mm ~ 250mm rotor futhiΦ I-impeller enobubanzi obungu-85mm kuya ku-350mm. Ukuhlanzeka okuphezulu kwe-graphite rotor inezici zamandla aphezulu, ukumelana nokushisa okuphezulu, nokumelana nokugqwala kwe-aluminium, okungasebenza ngokuzinza ezindaweni ezinokushisa okuphezulu.
Cukufakwa
Kafushane, ama-graphite rotor okwenziwa kwe-aluminium adlala indima ebalulekile ekubunjweni kwe-aluminium alloy, ukuthuthukisa ikhwalithi nokuzinza kokusakazwa kwe-aluminium alloy ngokuhlanza incibiliko ye-aluminium. Ama-graphite rotor anempilo ende yesevisi kanye nokusebenza kahle kokukhipha umoya nokuhlanza okuphezulu, okunganciphisa izindleko zokucubungula, ukusetshenziswa kwegesi engasebenzi, nokuqukethwe kwe-aluminium ku-slag, ukuthuthukisa ukusebenza kahle kokusakaza kanye nezindleko zokukhiqiza. Ngokuklama okunengqondo nokukhethwa kwezicaciso ezifanele, ama-graphite rotor angahlangabezana nezidingo zemigqa yokukhiqiza ehlukene ye-aluminium alloy casting, ehlinzeka ngokusekela okuthembekile kanye nesiqinisekiso sokuthuthukiswa kwemboni ye-aluminium alloy casting. Ngenqubekelaphambili eqhubekayo yobuchwepheshe bokukhiqiza, ama-graphite rotor okukhishwa kwe-aluminium azoqhubeka nokudlala indima ebalulekile emkhakheni we-aluminium alloy casting, ukushayela ukuthuthukiswa okuqhubekayo kanye nokusha kwale mboni.
