Zithini iimfuno ezikhethekileyo zeebheringi zeenjini zeenqwelo-moya, kwaye ungafikelela njani ekuxhathiseni nasekuthambiseni amaqondo obushushu aphezulu?

 

Okokuqala, masiqonde iimeko zokusebenza kweenjini zeenqwelo-moya:

 

1. Isantya esiphezulu, isantya senjini yenqwelo-moya ngokubanzi singaphezulu kwe-18000 rpm, kwaye iimfuno zezinto zokwakha ziphezulu kakhulu ngesantya esiphezulu kangaka.

 

2. Ubushushu obuphezulu, ubushushu bokusebenza kwenjini buphezulu kakhulu, ubushushu bokusebenza kwebheriya bunokufikelela kwi-300 °C, izinto zebheriya kufuneka zikwazi ukumelana nobushushu obuphezulu.

 

3. Ukuthembeka okuphezulu, nokuba yinqwelo-moya yoluntu okanye inqwelo-moya yokulwa, iimfuno zokuthembeka ziphezulu kakhulu, kwaye umahluko omncinci echibini ngumbandela wobomi bomntu.

 

Ngenxa yeubushushu obuphezulu bokusebenza kwebhereyitha, isangqa sangaphandle senziwe ngezinto ze-AISI M50 ezinokumelana nobushushu obuphezulu kunye nozinzo lobushushu obuphezulu, ezisenokufikelela kubunzima be-58HRC kwi-300°C.

Xa isebenza ngesantya esiphezulu, kuba iringi yangaphakathi yebheri iyajikeleza, amandla e-centrifugal makhulu kakhulu, kwaye icandelo elinqamlezileyo leringi yangaphakathi yebheri lithwala uxinzelelo lokuxinana olujikelezayo, ngoko ke akunakubakho mikroskopu kumphezulu weringi yangaphakathi ukuze kuthintelwe ukwanda kwemiqhekezo phantsi koxinzelelo lokuxinana, ngoko ke izinto ze-AISI M50NiL zihlala zisetyenziswa njengeringi yangaphakathi.

 

Ngenxa yesantya esiphezulu kakhulu, ukuze kuncitshiswe umthwalo owongezelelweyo oziswa ngamandla e-centrifugal ebhola yentsimbi, izinto zeseramikhi ezinobunzima obuphantsi kunye nobunzima obuphezulu, njenge-silicon nitride (Si3N4) okanye i-titanium carbide (TiC), zihlala zisetyenziswa njengezinto zebhola yentsimbi, kwaye ngamanye amaxesha ukuze kwandiswe ukumelana nokuguguleka kweendandatho zangaphakathi nezangaphandle zebheri kunye nokunciphisa ukungqubana, iindlela zomdyarho zangaphakathi nezangaphandle nazo zitshizwa ngeeseramikhi.

 

Ubushushu benjini bunokuba ngaphezulu kwama-300°C, obona buphezulu bungaphezulu kwama-1500°C, indlela yokuthwala ubushushu yi-300°C kuphela, le yimali exabisekileyo yenkqubo yokuthambisa, eneneni, inkqubo yokuthambisa ethwalayo inomsebenzi ophambili kukupholisa.

Inxalenye yayo kukuthambisa, ukuthambisa okuthwala injini kufana nokuthambisa kweebheringi ezibanzi, kuba isantya sokuthambisa siphezulu kakhulu, asinakusebenzisa ukutywina okuchukumisayo, ngoko ke ibheringi yenjini yindlela yokuthambisa ye-labyrinth, kodwa ioli yokuthambisa ayisebenzisayo ingcono kakhulu, kuba ubushushu bokusebenza buphezulu kakhulu, ioli yokuthambisa eqhelekileyo kulula ukuyithambisa kwaye yonakale, ngoko ke isetyenziswa ngokubanzi ioli yokwenziwa i-MIL-PRF23699HTS.
