1. Lub hom phiaj ntawm rail lubrication yog dab tsi?
Lubrication txo lub log -rail kev sib txhuam, txo suab nrov thiab hnav. Cov txheej txheem suav nrog:
Onboard lubrication systems: Txau cov roj nplua nyeem los ntawm cov tsheb ciav hlau.
Cov roj lubricator: Kho cov khoom siv nyob ze ntawm cov kab nkhaus.
2. Dab tsi yog lub neej ntev ntawm cov ntsia hlau?
Nyob ntawm cov tsheb thauj khoom thiab ib puag ncig, cov tsheb ciav hlau kawg10-20 xyoo. Hnyav-cov kab los yog cov nkhaus nkhaus nrawm nrawm, yuav tsum tau hloov ua ntej.
3. Cov txheej txheem rau kev hloov tsheb ciav hlau yog dab tsi?
Vertical hnav> 6mm (rau 60kg / m rails).
Sab hnav> 10mm.
Extensive spalling los yog internal tawg.
4. Lub hom phiaj ntawm kev sib tsoo tsheb ciav hlau yog dab tsi?
Kev sib tsoo rov ua kom txoj kev tsheb ciav hlau du du, tshem tawm corrugation thiab micro - tawg. Nws suav nrogtiv thaiv kev sib tsoo(regular) thiabkho kev sib tsoo(rau kev puas tsuaj).
5. Dab tsi tshwj xeeb yuav tsum tau siv rau txoj kab ntawm txoj kab nkhaus?
Kev ntsuas dav dav: Txo flange hnav.
Superelevation: Counters centrifugal quab yuam.
Txhim kho fastening: Tiv thaiv kev txav mus rau sab nraud.
