Tete'e La'ei Maualuga
Tete'e A'a Maualuga
Vaega Autu
Ole silicon nitride degassing rotor, fa'atasi ai ma le silicon nitride e fai ma ana mea autu, fa'atasi ai le ultra-maualuga-saosaoa mamanu ma le fa'atonu tonu o le fa'atonuga, fa'ataunu'uina fa'ataunu'u fa'atinoga i le fa'agasologa o le fa'agasologa o alumini. O ona uiga autu e faapea:
I. Mea Lelei: Tete'e o le vevela, La'ei Tetee, ma Leai Fa'aleaga
- Tulaga Sili i luga o le Graphite: O le rotor ma le impeller e faia i le nitride silicon. O lona fa'agaioiga sa'o ma le malosi e sili mamao atu nai lo le graphite, lagolago i le ultra-maualuga-saosaoa suiga (e o'o atu i le 8,000 rpm) ma fa'ateleina le ola tautua.
- Maualuluga - Temperature Oxidation Resistance: E toetoe lava a leai se faʻamaʻi i totonu o le maualuga - vevela siosiomaga, aloese mai le faʻafitauli o le "faʻaleagaina o alumini uʻamea" ma faʻamautinoa le mama o oloa.
- Chemical Inertness: E le tali atu i le alumini uʻamea, faʻamautu lelei le faʻaleagaina o le faʻaogaina mo se taimi umi. E leai se mea e popole ai e uiga i mea faʻaleagaina e aʻafia ai le faʻatinoga.
II. Fa'atonu Fa'atonu: Fa'amaumau Maualuluga - Saosaoa Fa'agaioiga, Fa'asaga Mafolafola
- Ultra - High Concentricity: O le concentricity o le rotor e matua pulea i totonu ole 0.2 mm (lea 1 "siliki" = 0.01 mm). I le taimi maualuga-saosaoa suiga, o le vibration e matua laʻititi lava, faʻamutaina le fesuiaiga o luga o le vai e mafua mai i le faʻalavelave.
- Faiga Feso'ota'iga Sa'o: O le ulu o le rotor ma le 'au fa'afeso'ota'i o lo'o faia i le u'amea u'amea, fa'atasi ai ma le fa'agaioiga sa'o e o'o atu i le 0.01 - mm maualuga. Fa'atasi ma le fa'apotopotoga maualuga, "fa'ato'a maualuga le ta'avale saosaoa" e maua, fa'aitiitia ai le fesuisuia'i o luga ole alumini fa'ameamea ma fa'amautinoa le mautu o le gaosiga.
III. Fa'aleleia o Fa'atinoga: Lelei, Fa'amaoni, ma Fa'aitiitiga Tau
- Maualuga Maualuga + Malosi Maualuga: O nei mea e lua e faʻamautinoa ai le faʻatuatuaina o le faʻatulagaina ma leai se faʻalavelave faʻalavelave i le taimi o le ultra-high-speed operation, e mafai ai ona fetuunai i tulaga ogaoga o galuega.
- Tulaga Eseese Faatusatusa: Faʻatusatusa i graphite rotors, e manaʻomia se taʻitaʻia atoatoa i le olaga tautua, faʻaleagaina o le faʻaleagaina, ma le maualuga-saosaoa fetuutuunai. E fa'aitiitia ai le tele o taimi e tapunia ai le tausiga ma fa'alilolilo le fa'aleleia lelei o le gaosiga.

Fa'afefea ona Filifili le Degassing Impeller?
Ituaiga F Rotor Φ250×33
Ona o le mamanu faʻapitoa o ona tootoo faʻamalosi ma nifo pito i fafo, o le Ituaiga F e fai ai ni pupuni laiti. O lona lapopoa o le impeller e faʻaleleia ai le faʻasalalau i le alumini uʻamea, ae o le impeller manifinifi e faʻaitiitia ai fesuiaiga o luga ole liusuavai.
Fa'aoga: E talafeagai mo laina fa'afefeteina mafolafola lapopo'a ma laina lapotopoto (faalua - rotor po'o le tolu - rotor degassing systems).
Ituaiga B Rotor Φ200×30
O le fa'apipi'i fa'apipi'i o le Ituaiga B e fa'atupuina ai le mamafa e fa'atupu ai ni pupuni la'ititi, tutusa ma fa'aitiitia ai le te'i vevela.
Fa'aoga: Fa'aoga mo le fa'aauauina o le lafo ma le ta'avale laina fa'afefeteina (tasi - rotor degassing systems).
Ituaiga D Rotor Φ200×60
O le Ituaiga D o lo'o fa'aalia ai se fa'ailoga uili fa'apipi'i fa'alua-lua, e mafai ai ona lelei le fa'avevesi ma le fa'asalalauina o pulu.
Fa'aoga: E talafeagai mo laina fa'afefeteina maualuga (faalua-rotor degassing equipment).

Silicon Nitride Ceramic Materials E manino lelei le lelei
Umi le tautua ma tau tausiga maualalo
Ona o le maualuga o le malosi o le vevela, teteʻe malosi o le vevela, ma le lelei o le corrosion resistance o le silicon nitride ceramics, o lo latou ola tautua e masani lava ona sili atu ma le tasi le tausaga, ma faʻaitiitia ai le tau sui ma le tausiga.
Leai se filogia i alumini liusuavai
Silicon nitride e maualalo le susu i u'amea u'amea ma seasea tali atu i alumini u'amea. O le mea lea, o le a le mafua ai le faʻaleagaina lona lua i le alumini uʻamea, lea e fesoasoani tele mo le faʻamautuina o le lelei o oloa lafo.
Faʻafaigofie le faʻapipiʻiina ma le tausiga
Silicon nitride ceramics e mafai ona faatumauina le malosi faʻafesoʻotaʻi e sili atu i le 500MPa ma lelei le teteʻe o le vevela i lalo ole 800 ℃. O le mea lea, o le mafiafia o le puipui o le oloa e mafai ona sili atu ona manifinifi. E le gata i lea, ona o le maualalo o le susu i uʻamea uʻamea, e le manaʻomia le faʻaogaina o se faʻapipiʻi luga, lea e faʻafaigofie ai le faʻapipiʻiina ma le tausiga o masini.
