I-graphite Rotor

I-graphite rotor ne-graphite impeller zenziwe nge-high-purity graphite. Ubuso buphathwa nge-anti-oxidation ekhethekile, futhi impilo yesevisi icishe ibe kathathu kunaleyo yemikhiqizo ejwayelekile. It is kabanzi aluminium ingxubevange ekubunjweni umkhakha.

Inqubo yokuhlanzwa kwe-liquid aluminium alloy iyindlela esemqoka yokuthuthukisa ukusebenza okuphelele kwe-aluminium alloy. Enqubeni yokuhlanzwa, indlela yokuxuba igesi yokuhlanzwa kanye ne-solvent kanye nokufafaza i-graphite rotor ku-aluminium melt yokuhlanzwa kuyindlela yokwelashwa esezingeni eliphakeme kakhulu emhlabeni. Umgomo osebenzayo we-graphite rotor uwukuthi: i-Rotor ejikelezayo iphula i-nitrogen (noma i-argon) eshaywa ku-aluminium incibilika ibe yinani elikhulu lamabhamuza ahlakazekile futhi ayihlakaza ensimbi encibilikisiwe. Amagwebu ancibilikayo ancike ekuhlukeni kwengcindezi ngokwengxenye yegesi kanye nomgomo wokukhishwa komhlaba ukumunca i-hydrogen kule melt, adsorb oxidized slag, futhi ikhishwe endaweni encibilikayo njengoba amagwebu ekhuphuka, ukuze ukuncibilika kuhlanzwe. Ngenxa yokuthi amabhamuza mancane futhi ahlakazekile, ahlanganiswa ngokulinganayo nokuncibilika okujikelezayo, bese ephenduka esimweni sokuvunguza ukuze antante kancane. Isikhathi sokuxhumana nokuncibilika side, futhi ukugeleza komoya okwenziwe ngokunyuka okuqhubekayo komugqa ngeke kwakhiwe, ngaleyo ndlela kususwe i-hydrogen eyingozi ku-melt aluminium. Impumelelo yokuhlanzwa.

Okwezisekelo ze-aluminium alloy nezimboni zomkhiqizo we-aluminium, kubaluleke kakhulu ukunciphisa izindleko zokucubungula. Mayelana nalokhu, ama-graphite rotors akhiqizwa inkampani yethu angaletha izinzuzo ezilandelayo. 1. Nciphisa izindleko zokucubungula 2. Nciphisa ukusetshenziswa kwegesi engena ngaphakathi 3. Nciphisa okuqukethwe kwe-aluminium esilahleni 4. Nciphisa izindleko zabasebenzi 5. Thuthukisa ukusebenza, umjikelezo omude wokufaka okunye esikhundleni 6. Thuthukisa ukwethembeka futhi wehlise izindleko zokuyigcina.

Ngoba imininingwane yama-rotor graphite asetshenziswa kulayini ngamunye wokukhiqiza noma wokulingisa awufani. Okokuqala, ikhasimende lihlinzeka ngemidwebo yokuqala yokuklama futhi ligcwalise ifomu lenhlolovo yemvelo eliphelele le-graphite rotor field. Bese kuthi, ngokusho kwemidwebo, kuhlanganiswe nesivinini se-graphite rotor, isiqondiso sokuzungeza kanye nokuma kwaso okulinganiselwe nezinga le-aluminium liquid, ukuhlaziywa kobuchwepheshe kuyenziwa, futhi kuphakanyiswa ukumelana nokuguguleka okufanelekile. Uhlelo lokwelashwa kwe-oxidation.

Umsizi ojikelezayo we-graphite rotor wenziwe nge-high-purity graphite. Ngaphezu kokubheka isidingo sokuqeda amabhamuza, isakhiwo sombhobho sisebenzisa amandla we-centrifugal akhiqizwe ngokunyakazisa i-aluminium alloy melt ukwenza ukuncibilika kungene embhobho futhi kuhlangane ngokulinganayo negesi ekhishwe ngokuvundlile ukwakha igesi / I-jet ketshezi kufuthwe ukuze kwandiswe indawo yokuxhumana nesikhathi sokuxhumana sebhamuza ne-aluminium alloy liquid, futhi kuthuthukise umphumela wokuhlanzwa kwe-degassing.

Ijubane le-graphite rotor lingalungiswa ngokungenantambo ngokulawulwa kwejubane lokuguqula isivinini, kuze kufike ku-700r / min. Incazelo ye-graphite rotor yi-Φ70mm ～ 250mm, futhi incazelo ye-impeller yi-mm85mm, 350mm. I-high-purity anti-oxidation graphite rotor inezici zamandla aphezulu, ukumelana nokushisa okuphezulu, kanye ne-aluminium flow corrosion resistance. Enkambisweni yokuhlanzwa nokugcotshwa, ubuso bolwelwesi lwe-aluminium alloy ebhokisini lumbozwe nge-nitrogen ukuvikela, ukuze ingxenye yerotite ye-graphite evezwe kuketshezi lwe-aluminium ingaphakathi kwegesi engenawo amandla ukuvimbela ukushisa okuphezulu kwe-oxidation i-Rotor futhi yelula impilo yenkonzo ye-Rotor.

Ukuma kwempepho kuhlanjululwa, okunganciphisa ukumelana ngesikhathi sokushintshana, namandla okuxabana nawokushayisana phakathi kwempepho ne-aluminium alloy liquid mancane. Ukuze izinga lokususa ingaphezulu kwama-50%, lifinyeze isikhathi sokuncibilikisa futhi lehlise izindleko zokukhiqiza.
