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 s...read more

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.
