i-rotor yegraphite

1. Ii-rotor yegraphiteisebenza ngokuqhubekayo kwi-aluminium inyibilika malunga ne-750 ° C ngesantya se-200r / min ~ 400r / min, kwaye ubomi benkonzo jikelele bufunekayo ukufikelela ngaphezu kwenyanga enye.Iigraphite i-rotoryenkampani yethu yenziwe ngegraphite ecocekileyo.Umgangatho wegraphite ngokwawo unempembelelo ebalulekileyo kubomi benkonzo ye-rotor.Ngelo xesha, i-anti-oxidation yokukhusela i-coating ifakwe phezu komhlaba, kwaye ubomi benkonzo bunokwandiswa kwiintsuku ezingama-50-60.

2. Umgaqo osebenzayo we-graphite rotor:

I-rotor yegraphite yenziwe ngentonga ye-rotor kunye ne-nozzle.Inkqubo yokuhambisa iqhuba i-rotor yegraphite ukuba ijikeleze, kwaye i-argon okanye i-nitrogen ivuthelwa kwi-aluminium inyibilika ngentonga ye-rotor kunye ne-nozzle.I-rotor ye-graphite ejikelezayo ephezulu iqhekeza i-argon okanye igesi ye-nitrogen engena kwi-aluminium inyibilika ukuze yenze amaqamza amancinci amaninzi, awasasaze kwintsimbi etyhidiweyo.Xa amaqamza adibene, amaqamza akunyibiliko axhomekeke kumohluko werhasi yoxinzelelo oluyinxenye kunye nomgaqo wobume beadsorption ukufunxa ihydrogen ekunyibilikeni, i-adsorb oxidized slag, kwaye ikhutshwe kumphezulu onyibilikayo njengoko amaqamza enyuka ukuze ahlambuluke. ukunyibilika.

Ukusetyenziswa kunye nokugcinwa kwerotha yegraphite:

1. Umbhobho ojikelezayo wenziwa ngegraphite ecocekileyo.Ukongeza ekuqwalaseleni ubume bombhobho wokwaphula amaqamza omoya, ikwasebenzisa amandla ecentrifugal aveliswa ngokushukumisa ingxubevange yealuminiyam enyibilikayo ukuze inyibilike ingene emlonyeni kwaye idibanise nerhasi ekhutshwa ngokuthe tye ukwenza irhasi.or ukuhamba kwamanzi kukhutshiwe ukunyusa indawo yoqhagamshelwano kunye nexesha loqhagamshelwano phakathi kwamaqamu kunye ne-aluminium alloy liquid, kunye nokuphucula i-degassing kunye nesiphumo sokucoca.

2. Imfuno yobomi benkonzo ngokubanzi ingaphezulu kwenyanga enye.Ukuqina kumaxesha angama-3-4 angcono kune-rotor engeyona i-oxidizing.Inokuhlala ukuya kwiintsuku ezingama-55-65 malunga ne-700 °C, kwaye inokuhlala ukuya kwiintsuku ezingama-25-35 kumaqondo obushushu angaphezu kwe-1000 °C.Ngokhuselo oluchasene ne-oxidation ebusweni, ubomi benkonzo bunokwandiswa ukuya kwiintsuku ezingama-50-60.

3.Ngaphambi kokuntywila i-rotor ye-graphite kwi-aluminium liquid, yitshise imizuzu emi-5 ukuya kwimizuzu eyi-10 malunga ne-100 mm ngaphezu kwendawo yamanzi ukuze ugweme impembelelo yokupholisa ngokukhawuleza kwizinto eziphathekayo;Ngaphambi kokuba i-rotor ifakwe kwi-liquid, igesi kufuneka idlule; Ukunikezelwa komoya kunokumiswa kuphela emva kokuba i-rotor iphakanyiswe kwinqanaba le-liquid, ukwenzela ukukhusela umgodi womoya we-rotor nozzle ukuba uvaliwe.

4. Isizathu esiyintloko somonakalo we-graphite rotor yi-oxidation ephezulu yokushisa: icandelo eliphambili legraphite yikhabhoni, kunye negraphite inokubonakala i-oxidized phantsi kweemeko zomoya ezidlula i-600 ° C. Iimveliso ze-carbon oxidation reactions yi-CO kunye ne-CO2 gases, leyo ayikwazi ukukhusela i-rotor.Ngokuqhelekileyo, ibhokisi ye-degassing ayikwazi ukutywinwa ngokupheleleyo, kwaye ininzi yebhokisi yangaphakathi yebhokisi ayigcwaliswanga ngegesi ekhuselayo, ngoko ke i-oxidation ye-graphite rotor ayinakuphepheka.Ngenxa ye-oxidation yayo, i-shaft diameter ye-rotor shaft iyancipha ngokuthe ngcembe ide iphule kwaye ikhutshwe.
