Cov kev cai tshwj xeeb rau cov kabmob cav dav hlau yog dab tsi, thiab yuav ua li cas thiaj ua tiav qhov kub thiab txias siab thiab lubrication?

 

Ua ntej tshaj plaws, cia peb nkag siab txog cov xwm txheej ua haujlwm ntawm cov cav dav hlau:

 

1. Kev kub ceev, qhov ceev ntawm lub cav dav hlau dav dav yog ntau dua 18000 rpm, thiab cov kev xav tau rau cov ntaub ntawv yog siab heev ntawm qhov ceev ceev.

 

2. Kub heev, qhov kub ua haujlwm ntawm lub cav siab heev, qhov kub ua haujlwm ntawm tus kabmob kuj tseem yuav ncav cuag 300 ° C, cov khoom siv ntawm tus kabmob yuav tsum muaj peev xwm tiv taus qhov kub siab.

 

3. Kev ntseeg siab siab, txawm tias nws yog lub dav hlau pej xeem lossis lub dav hlau sib ntaus sib tua, qhov yuav tsum tau ua kom ntseeg tau siab heev, thiab qhov sib txawv me ntsis hauv pas dej ua ke yog qhov teeb meem ntawm tib neeg lub neej.

 

Vim yog qhovkub ua haujlwm siab ntawm cov kabmob, lub nplhaib sab nraud yog ua los ntawm AISI M50 cov khoom siv nrog kev tiv taus kub thiab kev ruaj khov kub, uas tseem tuaj yeem ncav cuag 58HRC hardness ntawm 300 ° C.

Thaum khiav ntawm qhov ceev ceev, vim tias lub nplhaib sab hauv ntawm cov kabmob tig, lub zog centrifugal loj heev, thiab qhov seem ntawm lub nplhaib sab hauv ntawm cov kabmob dais lub zog tensile hoop, yog li tsis muaj qhov tawg me me ntawm qhov chaw ntawm lub nplhaib sab hauv kom tsis txhob muaj qhov tawg loj hlob hauv qab kev ntxhov siab tensile, yog li AISI M50NiL cov khoom siv feem ntau siv ua lub nplhaib sab hauv.

 

Vim yog qhov ceev heev, txhawm rau kom txo qhov hnyav ntxiv uas coj los ntawm lub zog centrifugal ntawm lub pob hlau, cov khoom siv ceramic nrog qhov hnyav sib dua thiab qhov nyuaj siab, xws li silicon nitride (Si3N4) lossis titanium carbide (TiC), feem ntau yog siv ua cov khoom siv pob hlau, thiab qee zaum txhawm rau ua kom muaj kev tiv thaiv hnav ntawm cov nplhaib sab hauv thiab sab nraud ntawm cov kabmob thiab txo qhov kev sib txhuam, cov nplhaib sab hauv thiab sab nraud kuj tau txau nrog cov khoom siv ceramic.

 

Qhov kub ntawm lub cav tuaj yeem ntau dua 300 ° C, qhov siab tshaj plaws yog ntau dua 1500 ° C, yuav ua li cas dais qhov kub tsuas yog 300 ° C, qhov no yog qhov credit ntawm lubrication system, qhov tseeb, lub cev lubrication system kuj muaj lub luag haujlwm tseem ceeb yog txias.

Ib feem ntawm nws yog lubrication, lub cav bearing lubrication zoo ib yam li lubrication ntawm cov bearings dav dav, vim tias qhov ceev ntawm lub bearing siab dhau, tsis tuaj yeem siv kev sib cuag sealing, yog li lub cav bearing yog labyrinth sealing txoj kev, tab sis cov roj lubricating uas nws siv zoo dua, vim tias qhov kub ua haujlwm siab dhau, cov roj lubricating dav dav yooj yim oxidized thiab lwj, yog li nws feem ntau siv cov roj hluavtaws MIL-PRF23699HTS.
