I-rotor yegraphite yokuphosa i-aluminium

Intshayelelo yeMveliso:

Umgaqo wokusebenza we-ai-rotor yegraphitekukuba i-rotor ejikelezayo iphula i-nitrogen (okanye i-argon) ivuthelwe kwi-aluminium inyibilika ibe ngamaqamza amaninzi ahlakaziweyo kwaye iwasasaze kwisinyithi esityhidiweyo. Amaqamza akwiqondo lokunyibilika afunxa i-hydrogen ekunyibilikeni okusekwe kumgaqo-siseko womahluko woxinzelelo oluyinxenye yerhasi kunye ne-adsorption yomphezulu, i-adsorb oxidation slag, kwaye ikhutshwa kumphezulu onyibilikayo njengoko amaqamza enyuka, nto leyo eyenza ukuba inyibilika icocwe. Ngenxa yokusasazwa kakuhle kwamaqamza, axuba ngokulungeleleneyo nenyibiliko ejikelezayo kwaye athi chu ukudada ukuya phezulu kwimilo ejikelezayo. Banexesha elide lokudibanisa kunye nokunyibilika kwaye musa ukwenza umoya oqhubekayo othe tye ukuya phezulu, ngaloo ndlela ususa i-hydrogen enobungozi kwi-aluminium inyibilika kunye nokuphucula kakhulu umphumo wokucoca.

Iimpawu zeemveliso ze-graphite rotor:

1. I-graphite rotor ejikelezayo i-nozzle yenziwe ngegraphite ephezulu. 2. Emva konyango oluphezulu, ubomi benkonzo bumalunga namaxesha amathathu eemveliso eziqhelekileyo, kwaye isetyenziswa ngokubanzi kwi-aluminium alloy casting industry.

Ngokoqoqosho lwegraphite rotor:

Kwiimveliso ze-aluminium alloy kunye neefektri zemveliso ye-aluminium, kubalulekile ukunciphisa iindleko zokusebenza. Kule nkalo, iirotor zegraphite eziveliswe yinkampani yethu zinokuzisa ezi zibonelelo zilandelayo:

1. Ukunciphisa iindleko zokusebenza

2. Ukunciphisa ukusetyenziswa kweegesi ze-inert

3. Ukunciphisa umxholo we-aluminium kwi-slag

4. Ukunciphisa iindleko zabasebenzi

5. Ukusebenza, umjikelo omde wokutshintshwa

6. Ukuphucula ukuthembeka nokunciphisa iindleko zokugcina.

Uyilo kunye nolandelelwano lweerotha zegraphite:

Ngenxa yeenkcazo ezahlukeneyo ze-graphite rotors ezisetyenziselwa ukuphosa okanye umgca wokuvelisa. Okokuqala, umthengi uya kubonelela ngemizobo yoyilo lwangaphambili kunye nefomu epheleleyo yovavanyo lwendawo yokusetyenziswa kwendawo yegraphite rotor. Emva koko, ngokusekelwe kwimizobo, uhlalutyo lobugcisa luya kuqhutywa ukudibanisa isantya, isalathiso sokujikeleza, kunye nendawo ehambelanayo kunye nenqanaba le-aluminium engamanzi ye-graphite rotor, kunye nesicwangciso esifanelekileyo sonyango lokulwa nokhukuliseko luya kuphakanyiswa.

I-graphite rotor ejikelezayo umlomo wenziwa ngegraphite ephezulu. Ukongeza ekuthatheni ingqalelo imfuneko yokusasaza amaqamza, ubume bombhobho bukwasebenzisa amandla e-centrifugal aveliswa ngokushukumisa ingxubevange ye-aluminiyam enyibilikayo ukuze ixube ngokulinganayo inyibilika kumlomo kunye nerhasi etshizwe ngokuthe tye, yenze irhasi/ulwelo lokuhamba ukutshiza ngaphandle. , ukwandisa indawo yoqhagamshelwano kunye nexesha lokudibanisa phakathi kweebhubhu kunye ne-aluminium alloy liquid, kunye nokuphucula i-degassing kunye nefuthe lokucoca. Isantya se-rotor yegraphite sinokuhlengahlengiswa ngaphandle kwenyathelo ngolawulo lwesantya sokuguqula isantya, ukuya kuthi ga kwi-700? R/min. Ukucaciswa kwe-graphite rotor ngu-Φ 70mm ~ 250mm, kunye neenkcukacha ze-impeller ye-Φ 85mm ~ 350mm, i-rotor ye-graphite ecocekileyo ineempawu ezifana namandla aphezulu, ukumelana nokushisa okuphezulu, kunye ne-aluminium flow flow corrosion resistance. Ngexesha lokuhlanjululwa kunye nenkqubo yokukhupha, i-nitrogen iqaliswa ukugubungela umphezulu we-aluminium alloy liquid ngaphakathi kwebhokisi yokukhusela, ukugcina indawo evelele ye-graphite rotor kwi-gas inert ukukhusela i-oxidation ephezulu ye-rotor kunye nokwandisa inkonzo yayo. ubomi. Ubume be-impeller buhlanjululwe, obunokunciphisa ukuchasana ngexesha lokujikeleza, kunye ne-friction kunye ne-rosion force eyenziwa phakathi kwe-impeller kunye ne-aluminium alloy liquid nayo incinci. Oku kukhokelela kwisantya sokukhupha umoya esingaphezulu kwe-50%, ukunciphisa ixesha lokunyibilikisa, kunye nokunciphisa iindleko zemveliso.
