Thaum lub sijhawm ua haujlwm ntawm cov chav turbine, lub siab-siab inlet yeeb nkab ntawm cov zog hluav taws xob siab ua lub luag haujlwm. Lub luag haujlwm tseem ceeb ntawm cov kab hluav taws xob no yog los thauj cov hluav taws xob kub thiab ua haujlwm siab ua haujlwm rau lub rotor, ua haujlwm ntawm lub tshuab hluav taws xob kom tig thiab tsim hluav taws xob nrawm. Vim yog lub siab kub siab heev thiab kub ntawm cov yeeb nkab, lub siab inlet yeeb nkab thiab nws cov bolts yuav tsum muaj peev xwm tiv thaiv txhua yam los ntawm kev nthuav dav ntawm thermal expansion thiab condaction.

Cov ntsia liaj qhov rooj ntawm lub siab-siab inlet yeeb nkab ntawm cov khoom siv siab siab yog qhov tseem ceeb ntawm lub tog raj hluav taws xob kom txuas rau lub zog siab siab thiab qhov dej siab. Yog li ntawd, kev xaiv ntawm bolt cov ntaub ntawv yog qhov tseem ceeb heev. 45CR1MOV yog ib qho kev ua tau zoo alloy steel dav siv rau hauv lub tshuab raj loj loj ua rau nws cov tshuab hluav taws xob siab thiab kub ua hauj lwm zoo.

45CR1Mov steel khoom muaj cov khoom siv zoo thiab cov cua sov tsis zoo thiab yog siv ntau rau kev tsim cov khoom siv kom muaj kub thiab cov khoom siv siab. Nyob rau hauv cov nqe lus ntawm corrosion tsis kam, 45cr1mov muaj qee qib ntawm corrosion tsis kam, tab sis nws tsis yog cov khoom siv tshwj xeeb rau kev xeb ib puag ncig. Yog li ntawd, nyob rau hauv ib puag ncig corrosive heev, tshwj xeeb tshaj yog nyob rau hauv muaj cov tshuaj lom neeg cov khoom siv tshuaj lom neeg, cov xeb tsis zoo ntawm 45 yam khoom siv rau cov khoom ntawd tshwj xeeb rau cov khoom muaj kev xeb.

Hais txog lub neej ua haujlwm, 45cr1mov cov khoom tuaj yeem tswj cov khoom siv zoo thiab cov qauv ruaj khov nyob hauv ib puag ncig kub thiab cov roj muaj peev xwm muaj lub neej muaj txiaj ntsig ntev dua. Txawm li cas los xij, lub neej pabcuam tiag yog cuam tshuam los ntawm ntau yam los ntawm ntau yam, suav nrog corrosion, qaug zog, thiab lwm yam. Yog li ntawd, hauv cov ntawv thov siv, nws yog qhov tsim nyog los tshawb xyuas thiab tswj cov bolts raws li kev ua haujlwm tshwj xeeb thiab hloov lawv tau raws li xav tau.

Hauv cov ntsiab lus, kev xaiv thiab kev xaiv ntawm cov khoom siv hluav taws xob siab rau cov khoom siv tshuab hluav taws xob muaj ntau yam zoo li cov khoom siv tshuab hluav taws xob, cov khoom siv hluav taws xob tsis kam, thiab kev pabcuam lub neej. Cov txheej txheem xaiv kom raug thiab nruj kev tsim qauv tuaj yeem ua kom muaj kev nyab xeeb, txuag, thiab txhim khu kev qha ua haujlwm ntawm cov huab cua turbines nyob rau hauv cov xwm txheej huab.

Yoyik tuaj yeem muab ntau yam khoom xa rau cov ntoo fais fab raws li hauv qab no:
