What is absolute expansion of steam turbine?
it's the thermal expansion in the casing of hp or ip turbine can be noticed by journal or thrust bearing when moving <<
What is use of thrust pad in steam turbine?
Thrust pads are used to protect the steam turbine rotor from damage due to axial displacement due to axial thrust created by entry of steam in the turbine. generaly the pads clearence is 0.45mm for a bearing size 250mm.
Angle of contact between journal and bearing?
0 degree
What is the function of a turbine bearing?
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.
Is journal bearing the same as sleeve bearing?
yes, just different namesNo.A sleeve bearing relies on contact to support the load. These bearings can carry large loads for their size and cost. But, they are very limited with regard to speed. They are also the best bearing for joints that do not turn a full 360° or continuous rotation. Example: Door HingeA journal bearing relies on a film of oil to keep the two parts from making contact. They work on a dynamics basis; that is the rotation of the journal (shaft) pulls the oil through the high pressure zone via the viscosity of the oil. Unlike sleeve bearings, journal bearings like speed. They do not do well if they are moving too slowly. They are the most durable bearing known. Example: Engine crank shaft, piston connecting rod to crank.Joey Lloyd, PE
Why journal bearing used in steam turbine?

What is turbine thrust bearing active and inactive temperature?
Turbine thrust bearing active and inactive temperature is the blade in the turbine trust bearing is actual temperature change, which mitigates the active or inactive bearing.
What are the types of bearings used in a steam turbine?

What is another name for rod journal?
bearing journal
What is bearing crush?
Interference between journal bearing to bearing housing is called bearing crush.
Did hydrodynamic journal bearing use in connecting rod bearing?
hydrodynamics is the study of fluids in motion. Your question needs to be reworded to make more sense.
Why journal is fitted inside a bearing?
engineering application of fitted bearing
What is a steam turbine jacking oil system?
at the time of turbine start up, the shaft journals are in contact with the white metal of the bearings due to the weight of the rotor. The low pressure of the lubricating oil supply when the set is stationary is insufficient to stop the metal to metal contact between journals and bearing shells. In order to prevent the metal to metal contact between journal and bearing shell during start up, which is damaging in the long term, an oil pocket machined into the bottom shell of the journal bearing is supplied with oil under high pressure. This lifts the shafting system slightly and it floats on a film oil. this is called jacking oil system of turbine
