cavitation usually, or a thrown blade on the impeller.
Insufficient lubrication and failure of Babbitt material causes cavitation prolem
because of the resonance speed
Yes . . .in order to reduce blade vibration and improved airflow characteristics . .
This relationship is the reason advances in turbines and axial compressors often find their way cutaway showing an axi-centrifugal compressor gas turbine.
in a radial flow turbine the steam enters the turbine in the direction of its radius and leaves it in the direction of the axis of the shaft. in a axial flow turbine the steam enters the turbine in the direction of the axis of the shaft and leaves the turbine in the same direction.
Turbine is the correct spelling.
becouse this steam is use repetdly for the turbine
What are the main reason of turbine blade failure?
Yes . . .in order to reduce blade vibration and improved airflow characteristics . .
2 main reasons: 1. Imbalance of the turbine, 2. Shock waves from the air (if it's spinning fast enough)
Shrouding serves toconfine steam to the passage of the turbine blades. It also helps to stiffen the blades against vibration.
It will be unbalanced and unable to run without heavy vibration as a result.
Paul Larvin has written: 'Static testing and modelling of a small turbine rotor to identify its vibration characteristics'
The TSI system is Turbine Supervisory Instrumentation system, consists of multiple instruments, including speed sensors, speed monitors and so on. The system continuously monitors the steam turbines of all important parameters, such as: rotational speed, overspeed protection, eccentricity, shaft vibration, cover vibration, axial displacement, differential expansion, and thermal expansion. The system helps to improve the availability of steam turbine unit.
Interlock system is in turbine for protect the turbine. different types of interlocks in turbine 1. high vibration, 2. Bearing oil Temp,3. vacuum related, 4. over speed, 5. differential expansion, 6. casing expansion, 7. lube oil header Pressure. 8. Axil shift. etc... . this interlocks is keep the turbine in safe mode in any abnormalities.
