Exam 6: Turbines and Motors

The lube oil system in a steam turbine lubricates bearings and gears, cools lubricated parts and acts as a hydraulic medium for the governor.

A typical governing system is divided into all of the following parts except:

Steam entry pressures into a steam turbine reach:

Turbines convert __________ __________ into useful mechanical energy that is used to drive rotating equipment.

A device used to connect the drive shaft of a motor or steam turbine to a pump, compressor or generator.

Identify the main parts of a gas turbine.

Modern turbine technology includes _____ or more stages linked axially along a horizontal shaft.

When a steam turbine speeds up or slows down while the controller searches for the correct operating speed is called:

In a steam turbine, the rotation of the blades in response to the steam is called:

Shaft seals are located at the ends of each casing to minimize outward leakage of steam under pressure and enhance inward air leakage.

A safety device used to shutdown a turbine when it exceeds rotational limits is called a:

The bearing that keeps the shaft from moving from side to side is called the:

Modern turbine design _________ the size of each stage giving the turbine a _________ shape.
