Diesel generator teeb bearings yuav muab faib ua yaw bearings, pitch bearings, kis kab mob system bearings (lub ntsiab ncej thiab gearbox bearings). Lub tshuab hluav taws xob teeb bearings feem ntau yog siv rau hauv cov khoom siv cua turbine, txhua cov khoom siv cua turbine siv ib txheej ntawm yaw bearing thiab peb pawg ntawm cov kabmob. Yog li cas cov neeg siv xaiv bearings rau diesel generator teeb tam sim no? Tus txheej txheem tshiab zoo li cas?
1. Cov txheej txheem yuav khoom tshiab tau teev tseg tias vim lub zog quab yuam ntawm cua turbine yaw thiab pitch bearings, thiab qhov cuam tshuam thiab kev vibration ntawm cov bearings yog qhov loj, nws yuav tsum tau hais tias cov bearings tuaj yeem tiv taus ob qho tib si thiab kev thauj khoom loj. Lub neej ntawm cov cua turbine lub ntsiab cav yuav tsum tau 20 xyoo, thiab tus nqi ntawm cov kabmob installation kuj loj, yog li lub neej ntawm lub yaw thiab suab bearings yuav tsum mus txog 20 xyoo. Nyob rau hauv txoj kev no, lub hardness ntawm bearing nplhaib puag yog 229HB-269HB, uas muaj peev xwm tiv taus tej yam tsis muaj yas deformation. Nyob rau tib lub sijhawm, qhov quenching hardness ntawm qhov kev sib tw nce mus txog 55HRC-62HRC, uas tuaj yeem ua rau kom muaj kev sib cuag qaug zog thiab ua kom lub neej ntev ntawm cov kabmob.
2. Qhov tseeb ntawm kev sib kis ntawm lub tshuab hluav taws xob diesel teeb bearings tsis siab, thiab txoj kab uas hla ntawm lub nplhaib iav yog qhov loj, thiab cov iav modulus kuj loj heev. Yog li, qhov tseeb ntawm cov iav feem ntau yuav tsum yog qib 9 lossis 10 hauv GB / T10095.2---2001. . Txawm li cas los xij, vim muaj kev cuam tshuam ntawm pinion iav thiab bearing nplhaib iav nyob rau hauv kev ua hauj lwm, cov hniav nto ntawm cov kabmob nplhaib iav yuav tsum tau quenched, thiab hardness ntawm pinion iav hniav nto yog feem ntau 60HRC. tsis tsawg dua 45HRC.
3. Rau lub yaw bearing, qhov cuam tshuam ntawm lub suab bearing yog qhov loj, thiab cua tshuab mus rau cov hniav thiab kev co kuj loj, yog li qhov kev tshem tawm ntawm lub suab bearing yuav tsum yog xoom lossis me ntsis tsis zoo. Nws tuaj yeem txo qhov fretting hnav ntawm cov kabmob.
4. Tsawg kub cuam tshuam lub zog xav tau rau yaw thiab pitch turntable bearing rings: -20 degree Akv tsis tsawg dua 27J. Cua turbines tuaj yeem ua haujlwm nyob rau hauv qhov chaw txias heev, qhov kub ntawm qhov nruab nrab yog qis li -40 bar, qhov ua haujlwm kub ntawm cov kabmob yog nyob ib ncig ntawm -20C, thiab cov kabmob yuav tsum muaj peev xwm tiv taus qhov poob siab loj hauv qhov kub thiab txias. Yog li ntawd, lub nplhaib bearing yog yuav tsum tau. Tom qab quenching thiab tempering, cov khoom siv yuav tsum raug rau qhov ntsuas kub ntawm qhov ntsuas hluav taws xob tsawg, thiab ib feem ntawm lub nplhaib bearing yog coj los ua cov qauv lossis cov qauv uas muaj kev ua haujlwm zoo ib yam thiab kev kho cua sov tib yam li lub nplhaib, thiab qhov kev cuam tshuam yog ua nyob rau hauv ib puag ncig ntawm -20C Kev Ntsuas Hluav Taws Xob.
Yog li ntawd, nyob rau hauv tus txheej txheem ntawm kev xaiv cov kabmob ntawm lub tshuab hluav taws xob teeb, peb xaiv cov kabmob uas ua tau raws li tus qauv rau lub sijhawm uas siv lub tshuab hluav taws xob. Kev xaiv ntawm cov kabmob ntawm lub tshuab hluav taws xob diesel teeb cuam tshuam rau kev ua haujlwm ruaj khov ntawm lub tshuab hluav taws xob teeb tsa rau qee qhov, yog li ceev faj thaum xaiv.
