Steel-forged Steam Turbine Marine Shaft
- HHF
- China
- 2 months
- 200pcs per month
THE SHAFT connects the turbine to the generator, turning at the same speed as the turbine.
Product Introduction
The shaft is the essential mechanical connector between the turbine and the generator, spinning in step with the turbine's rotation to supply mechanical energy that will then be transformed into electrical power. As an important part of the system, it is subjected to severe working conditions, therefore it must be made with the utmost precision, have strong structural resistance, and perform well under all conditions in order to guarantee continuous and high-efficient power supply.
