both are same using for rotating the turbine initially
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.
Ljungstrom Turbine is a Radial Outflow Steam Turbine with two counter rotating discs. Blades are mounted in circles one bigger than the other. Blades of one rotor work as nozzles for the other rotor blades. This turbine design is very forgiving on wet steam. It is said that the turbine design had limitations on scaling up above 30 MW and hence could not compete with Axial Flow Turbines.

They are a press fit
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.

1. For lubrication the bearings 2. For controlling the turbine 3. For sealing
Wear and corrosion, especially in bearings.
yes
Rotating axial compressor.
Commodity bearings are used in rotating elements that have relatively low revolutions per minute and do not face extreme stresses.
