Rotor Wheel Machining Stage 7
Customer: ENGIE Chile
Site: Central Termoeléctrica Tocopilla
Specialized machining of the rotor wheel for turbine stage 7 was performed under strict quality and dimensional accuracy standards. The service included inspection, measurement, and restoration of critical surfaces through high-precision machining, contributing to operational reliability and extending the equipment’s lifespan.
Balancing drum seal cuts
Customer: Central Termoeléctrica Norgener
Siter: AES Chile
The service involves the controlled removal of existing balance drum seals using specialized cutting and machining processes, ensuring the protection of base surfaces and preventing damage to adjacent components. This stage includes an initial dimensional inspection and measurements to determine the degree of wear present in the housings and reference surfaces.
Installation new seals
Controlled Machining
Once the mounting surfaces are restored, the new seal segments are manufactured or fitted, followed by their installation and alignment. During this phase, critical parameters such as concentricity, parallelism, and axial positioning are verified, ensuring compliance with the equipment’s technical specifications and applicable quality standards.
Check clearence and final dimensioning
Finally, the final machining of the installed seals is carried out to achieve the operational clearances defined by engineering. This activity optimizes the hydraulic and thermodynamic performance of the system, reducing internal losses, improving operational efficiency, and contributing to the reliability and availability of the generating unit.
