Turbines can rotate without traditional bearings by utilizing magnetic levitation (maglev) technology. In this system, powerful magnets create a magnetic field that lifts and stabilizes the rotor, allowing it to spin freely without physical contact. This eliminates friction, reducing wear and tear and increasing efficiency. Additionally, advanced designs may use air or fluid film lubrication to maintain a gap between moving parts, further enhancing performance.
A turbine bearing supports the rotating shaft of a turbine, allowing it to spin smoothly while minimizing friction and wear. It helps to maintain proper alignment and stability of the shaft during operation, which is crucial for efficient energy conversion. Additionally, turbine bearings can absorb vibrations and loads, contributing to the overall reliability and longevity of the turbine system. Proper lubrication and maintenance of these bearings are essential for optimal performance.

Rotating axial compressor.
turbo blower is an equipment where a turbine is attached with the blower part. steam enters through the turbine inlet and expands through the blades and goes to the outlet which helps the turbine shafts to rotate. this turbine shaft is attached with the shaft of blower that makes the blower rotating.
It is oil used to lubricate the bearings on the turbine. Typically designated AW32 oil, it is a high purity clear amber 300 ssu viscosity mineral oil with anti-wear additives. It is also used to operate the turbine's controls, such as the governor, trip mechanisms and admission valves.

Vibration in a turbine can occur due to various reasons such as imbalance in rotating components, misalignment of shafts, or worn out bearings. These factors can lead to uneven forces acting on the turbine, causing it to vibrate. Monitoring and addressing these issues promptly is important to prevent damage to the turbine and ensure efficient operation.
A jacking oil pump is used in turbine applications to provide lubrication and cooling to the bearings during startup and shutdown. It operates by delivering oil at a low flow rate to create a hydrodynamic film between the rotating shaft and the bearings, preventing metal-to-metal contact and reducing wear. Once the turbine reaches operational speed, the main lubrication system takes over, allowing the jacking oil pump to shut down. This process is crucial for ensuring the longevity and reliability of the turbine components.
