Ingcaciso yeMveliso

 I -Wind Turbine Main Shaft yokuBhengeza iNdlu licandelo lesiseko kwi-horizontal-axis iiinjini zomoya, ezinoxanduva lokuxhasa i-rotor shaft kunye nokuhambisa imithwalo ye-aerodynamic kwisakhelo se-nacelle. Isebenza phantsi komthwalo oqhubekayo wokulayishwa kwebhayisikile, ukuhluka kobushushu obugqithisileyo, kunye neemfuno zeminyaka engama-20+ yobomi benkonzo, eli candelo lifuna amandla akhethekileyo okudinwa, ukuzinza komda, kunye nesandi sesinyithi. 
 I-Ningbo Ruican ivelisa le ndlu ngokuchithwa kotyalo-mali oluchanekileyo lwe-QT700-2 yentsimbi ye-ductile, ilandelwa yi-5-axis CNC machining yemigangatho yesihlalo esibalulekileyo, iipateni zomngxuma webholithi, kunye nokunyuka kojongano. Imveliso yethu edibeneyo iqinisekisa ukulandeleka okupheleleyo ukusuka kwimathiriyeli ekrwada ukuya kwinxalenye egqityiweyo.
