i-graphite rotor
1. Ii-graphite rotorisebenza ngokuqhubekayo ekuncibilikeni kwe-aluminium cishe ku-750 ° C ngesivinini esingu-200r/min~400r/min, futhi impilo yesevisi evamile iyadingeka ukuze ifinyelele ngaphezu kwenyanga eyodwa.Ii-graphite i-rotoryenkampani yethu yenziwe nge-high-purity graphite.Ikhwalithi ye-graphite ngokwayo inomthelela omkhulu empilweni yesevisi ye-rotor.Ngesikhathi esifanayo, i-anti-oxidation protective coating isetshenziswa ebusweni, futhi impilo yesevisi inganwetshwa ezinsukwini ezingu-50-60.
2. Umgomo wokusebenza we-graphite rotor:
I-graphite rotor yenziwe nge-rotor rod kanye ne-nozzle.Isistimu yokudlulisela ishayela i-graphite rotor ukuthi ijikeleze, futhi i-argon noma i-nitrogen ivuthelwa ku-aluminium inyibilika nge-rotor rod kanye nozzle.I-graphite rotor egijima ngesivinini esiphezulu iphula i-argon noma igesi ye-nitrogen engena ku-aluminium encibilikayo ukuze kwakhe amabhamuza amaningi amancane, awahlakaze ensimbi encibilikisiwe.Uma amabhamuza ethintana, amabhamuza ekuncibilikeni ancike kumehluko wegesi ingxenye yengcindezi kanye nomgomo wokukhanga kwendawo ukuze amunce i-hydrogen ekuncibilikeni, i-adsorb oxidized slag, futhi akhishwe endaweni encibilikayo njengoba amabhamuza ekhuphuka ukuze ahlanzeke. ukuncibilika.
Ukusetshenziswa nokugcinwa kwe-graphite rotor:
- Umbhobho ojikelezayo wenziwa nge-high-purity graphite.Ngaphezu kokucabangela ukwakheka kombhobho ukuze kunqamuke amabhamuza omoya, iphinde isebenzisa amandla aphakathi nendawo akhiqizwe ukuncibilika kwe-aluminium alloy ukuze inyibilike ingene emlonyeni bese ixubana negesi ekhishwe ngokuvundlile ukuze yakhe igesi.or ukugeleza koketshezi kukhishwa ukuze kwandiswe indawo yokuxhumana kanye nesikhathi sokuxhumana phakathi kwamabhamuza noketshezi lwe-aluminium alloy, futhi kuthuthukiswe umphumela wokukhipha umoya nokuhlanza.
2. Imfuneko yempilo yesevisi evamile ingaphezu kwenyanga eyodwa.Ukuqina kungcono izikhathi ezi-3-4 kune-rotor engeyona oxidizing.Ingahlala izinsuku ezingama-55-65 cishe ku-700 °C, futhi ingahlala izinsuku ezingama-25-35 emazingeni okushisa angaphezu kuka-1000 °C.Ngesivikelo se-anti-oxidation ebusweni, impilo yesevisi inganwetshwa ibe yizinsuku ezingama-50-60.
3.Ngaphambi kokucwilisa i-graphite rotor oketshezini lwe-aluminium, yishise kuqala imizuzu emi-5 ukuya kweyi-10 cishe ngo-100 mm ngaphezu kwendawo ewuketshezi ukuze ugweme umthelela wokupholisa ngokushesha ezintweni;ngaphambi kokuba i-rotor icwiliswe oketshezini, igesi kufanele idlule; Ukunikezwa komoya kungamiswa kuphela ngemva kokuba i-rotor iphakamisile iphuma ezingeni le-liquid, ukuze kuvinjwe imbobo yomoya ye-rotor nozzle ukuthi ingavinjelwa.
4. Isizathu esiyinhloko sokulimala kwe-graphite rotor i-high-temperature oxidation: ingxenye eyinhloko ye-graphite yi-carbon, futhi i-graphite ingabonakala i-oxidized ngaphansi kwezimo zomoya ezingaphezu kuka-600 ° C. Imikhiqizo yokusabela kwe-carbon oxidation yi-CO ne-CO2 gases, okuyinto ayikwazi ukuvikela i-rotor.Ngokuvamile, ibhokisi le-degassing alikwazi ukuvalwa ngokuphelele, futhi ingxenye enkulu yangaphakathi yebhokisi ayigcwaliswa ngegesi evikelayo, ngakho-ke i-oxidation ye-graphite rotor ayinakugwenywa.Njengomphumela we-oxidation yayo, ububanzi be-shaft ye-rotor shaft buyancipha kancane kancane kuze kube yilapho buphuka futhi buchithwa.
