I-Silicon Nitride Degassing Rotor kwi-Degassing Machine ye-Aluminiyam Foundry
Izinto Zokomelela Okuphakamileyo
Ukumelana nokuNxitywa okuphezulu
Ukuxhathisa okuPhezulu kokuMnyama
Iimpawu eziphambili
I-silicon nitride degassing rotor, ene-silicon nitride njengeyona nto iphambili, idibanisa uyilo lwe-ultra-high-isantya kunye nolawulo oluchanekileyo lolwakhiwo, ukufezekisa impumelelo kwinkqubo yokukhupha i-aluminiyam. Iimpawu zayo eziphambili zezi zilandelayo:
I. Izinto eziluncedo: ukuxhathisa iqondo lobushushu, ukuNxiba ukuNxitywa, kwaye akukho ngcoliseko.
- I-Inherent Superiority Over Graphite: I-rotor kunye ne-impeller zenziwe nge-silicon nitride. Ukuchaneka kwayo kunye namandla ayodlula kude ezo zegraphite, exhasa i-ultra - high-speed rotation (ukuya kuthi ga kwi-8,000 rpm) kunye nokwandisa kakhulu ubomi benkonzo.
- I-High-Temperature Oxidation Resistance: Kukho phantse akukho oxidation kwiindawo eziphezulu zokushisa, ukuphepha ngokupheleleyo ingxaki "yokungcolisa i-aluminium etyhidiweyo" kunye nokuqinisekisa ukucoceka kwemveliso.
- Ukungangeni kweMichiza: Ayisebenzi nge-aluminiyam etyhidiweyo, igcina ngokuzinzileyo isiphumo sokukhupha umoya ixesha elide. Akukho mfuneko yakukhathazeka malunga nokuthotywa kwezinto ezichaphazela ukusebenza.
II. Ukuchaneka koLwakhiwo: UZinzile oPhezulu-Ukusebenza ngesantya, iFlat Molten Surface
- I-Ultra - I-High Concentricity: I-concentricity ye-rotor ilawulwa ngokungqongqo ngaphakathi kwe-0.2 mm (apho i-1 "silk" = 0.01 mm). Ngexesha lokujikeleza kwesantya esiphezulu, ukungcangcazela kuncinci kakhulu, kususa ukuguquguquka komphezulu wolwelo okubangelwa kukunyaniseka.
- Inkqubo yoQhagamshelwano oluchanekileyo: Intloko ye-rotor kunye ne-shaft yokudibanisa yenziwe ngensimbi engenasici, kunye nokuchaneka kokucubungula ukufikelela kwinqanaba le-0.01 - mm. Idityaniswe ne-high-precision assembly, “concentric high-speed drive” iphunyeziwe, inciphisa ukuguquguquka komphezulu otyhidiweyo we-aluminiyam nokuqinisekisa uzinzo lwemveliso.
III. Ukuphuculwa kokuSebenza: Ukusebenza kakuhle, ukuthembeka, kunye nokuNcitshiswa kweendleko
- Uxinaniso oluPhezulu + lwamandla aphezulu: Ezi zakhiwo zimbini ziqinisekisa ukuthembeka kwesakhiwo kwaye akukho mngcipheko wokuguqulwa ngexesha le-ultra - high-speed operation, okwenza kube lula kwiimeko zokusebenza ezigqithiseleyo.
- Izinto eziNgcono zokuthelekisa ezicacileyo: Xa kuthelekiswa ne-graphite rotors, kuthatha ukhokelo olubanzi kubomi benkonzo, ukuchasana nongcoliseko, kunye nokuguquguquka kwesantya esiphezulu. Inciphisa ukuphindaphinda kokugcinwa kokuvala kwaye ngokungathanga ngqo iphucula ukusebenza kakuhle kwemveliso.

Indlela yokukhetha i-Degassing Impeller?
Uhlobo lwe-F Rotor Φ250×33
Ngenxa yoyilo olukhethekileyo lwegrooves yayo kunye namazinyo angaphandle angaphandle, udidi F lubumba amaqamza amancinci. Ubukhulu bayo be-impeller enkulu bongeza ukusasazwa kwi-aluminiyam etyhidiweyo, ngelixa i-impeller ebhityileyo inciphisa ukuguquguquka komphezulu wokunyibilika.
Isicelo: Ifanelekile kwi-ingot enkulu ye-flat kunye nemigca yokunyibilika kwebar ejikelezayo (i-double - rotor okanye i-triple-rotor degassing systems).
Uhlobo B Rotor Φ200×30
Ulwakhiwo lwe-impeller yoHlobo lwe-B luvelisa uxinzelelo olwaneleyo lokudala amaqamza amancinci, afanayo ngelixa unciphisa ukothuka kwe-thermal.
Isicelo: Ifanelekile ukuphosa ngokuqhubekayo kunye nemigca yokunyibilika (i-single -rotor degassing systems).
Uhlobo lwe-D Rotor Φ200×60
Uhlobo D lubonisa isonka esiphindwe kabini - uyilo lwevili olumile, luvumela ukusasazwa okugqwesileyo kunye nokusasazwa kwamaqamza.
Isicelo: Ifanelekile kwimigca yokunyibilika okuphezulu (i-double - rotor degassing equipment).

I-Silicon Nitride Izinto zeCeramic ezicacileyo eziluncedo
Ubomi benkonzo ende kunye neendleko zokugcina eziphantsi
Ngenxa yamandla aphezulu obushushu, ukuxhathisa ukothuka kwe-thermal, kunye nokumelana okuhle kokutya kwe-silicon nitride ceramics, ubomi babo benkonzo ngokubanzi bufikelela ngaphezulu konyaka omnye, ngaloo ndlela behlisa iindleko zokutshintsha kunye nokugcina.
Akukho ngcoliseko kwialuminiyam etyhidiweyo
I-Silicon nitride inobumanzi obuphantsi kwiintsimbi ezityhidiweyo kwaye ayifane isabele ngealuminiyam etyhidiweyo. Ngoko ke, akuyi kubangela ungcoliseko lwesibini kwi-aluminium etyhidiweyo, eluncedo kakhulu ekuzinziseni umgangatho weemveliso ezityhidiweyo.
Ufakelo olulula kunye nokugcinwa
I-Silicon nitride ceramics inokugcina amandla aguquguqukayo angaphezulu kwe-500MPa kunye nokumelana nokothuka kwe-thermal ngaphantsi kwe-800 ℃. Ngaloo ndlela, ubukhulu bodonga lwemveliso bunokwenziwa buncinci. Ukongezelela, ngenxa yokumanzisa kwayo okuphantsi kwiintsimbi ezityhidiweyo, akukho mfuneko yokufaka i-coating surface, eyenza ukufakwa kunye nokugcinwa kwezixhobo kube lula.
