Litlhoko tse khethehileng tsa li-bearing tsa enjene ea lifofane ke life, le mokhoa oa ho fihlela khanyetso le ho tlotsa mocheso o phahameng?

 

Taba ea pele, ha re utloisiseng maemo a ts'ebetso ea lienjine tsa lifofane:

 

1. Lebelo le phahameng, lebelo la enjene ea sefofane se akaretsang le feta 18000 rpm, 'me litlhoko tsa thepa li phahame haholo ka lebelo le phahameng hakana.

 

2. Mocheso o phahameng, mocheso o sebetsang oa enjene o phahame haholo, mocheso o sebetsang oa bearing o ka boela oa fihla ho 300 °C, thepa ea bearing e hloka ho khona ho mamella mocheso o phahameng.

 

3. Ho tšepahala ho hoholo, ebang ke sefofane sa sechaba kapa sefofane sa ntoa, litlhoko tsa ho tšepahala li phahame haholo, 'me phapang e nyane letamong ke taba ea bophelo ba motho.

 

Ka lebaka lamocheso o phahameng oa ts'ebetso oa bearing, lesale le ka ntle le entsoe ka thepa ea AISI M50 e nang le khanyetso e phahameng ea mocheso le botsitso bo phahameng ba mocheso, e ntseng e ka fihla ho thata ea 58HRC ho 300°C.

Ha e matha ka lebelo le phahameng, hobane lesale le ka hare la bearing le potoloha, matla a centrifugal a maholo haholo, 'me karolo e tšekaletseng ea lesale le ka hare la bearing e na le khatello ea ho hula ha sekotlo, kahoo ho ke ke ha e-ba le mapetso a manyenyane holim'a lesale le ka hare ho qoba ho ata ha mapetso tlas'a khatello ea ho hula, kahoo thepa ea AISI M50NiL hangata e sebelisoa e le lesale le ka hare.

 

Ka lebaka la lebelo le phahameng haholo, e le ho fokotsa mojaro o eketsehileng o tlisoang ke matla a centrifugal a bolo ea tšepe, thepa ea ceramic e nang le boima bo bobebe le ho thatafala ho hoholo, joalo ka silicon nitride (Si3N4) kapa titanium carbide (TiC), hangata e sebelisoa e le thepa ea bolo ea tšepe, 'me ka linako tse ling e le ho eketsa khanyetso ea ho tsofala ha masale a ka hare le a ka ntle a bearing le ho fokotsa khohlano, litsela tsa mabelo a ka hare le a ka ntle le tsona li fafatsoa ka li-ceramic.

 

Mocheso oa enjene o ka ba ho feta 300 °C, o phahameng ka ho fetisisa o feta 1500 °C, mokhoa oa ho mamella mocheso ke 300 °C feela, ena ke tlotla ea sistimi ea ho tlotsa, ha e le hantle, sistimi ea ho tlotsa e nang le bearing e boetse e na le mosebetsi o ka sehloohong ke ho pholile.

Karolo ea eona ke setlolo, setlolo se nang le enjene se tšoana le setlolo sa li-bearings tse akaretsang, hobane lebelo la bearings le phahame haholo, ha le khone ho sebelisa setlolo sa ho kopana, kahoo setlolo sa enjene ke mokhoa oa ho tiisa oa labyrinth, empa oli ea setlolo eo a e sebelisang e betere haholo, hobane mocheso oa ts'ebetso o phahame haholo, oli ea setlolo e akaretsang e bonolo ho e oxidation le ho senyeha, kahoo hangata e sebelisoa oli ea maiketsetso ea MIL-PRF23699HTS.
