Turbine Operator Interview Questions and Answers

Vacuum is needed in turbines to create a pressure difference that drives the turbine blades and generates power.

• Vacuum creates a pressure difference that drives the turbine blades.

• The pressure difference causes the blades to rotate, converting kinetic energy into mechanical energy.

• The mechanical energy is then used to generate power.

• Vacuum is necessary for efficient turbine operation and power generation.

Barring gear is a mechanism used in turbines to rotate the rotor during maintenance or inspection.

• Barring gear is typically used in steam turbines and gas turbines.

• It consists of a gear system that connects to the rotor shaft.

• The gear system allows for controlled rotation of the rotor.

• Barring gear is used when the turbine is shut down and the rotor needs to be turned manually.

• It is commonly used for maintenance tasks such as blade inspection or cleaning.

• Barring gear helps pre...read more

Oil pressure is the pressure of oil in the lubrication system of the turbine.

• Oil pressure is important for proper lubrication of the turbine's moving parts.

• Low oil pressure can cause damage to the turbine's components.

• High oil pressure can indicate a blockage in the lubrication system.

• Oil pressure is typically measured in pounds per square inch (PSI).

An instrument mechanic is a skilled technician who installs, maintains, and repairs various instruments and control systems.

• Instrument mechanics work with a wide range of instruments and control systems, including pressure gauges, temperature sensors, flow meters, and control valves.

• They are responsible for installing and calibrating instruments to ensure accurate readings and proper functioning.

• Instrument mechanics troubleshoot and diagnose issues with instruments and contro...read more
