Atmastco Mechanical Maintenance Engineer Interview Questions and Answers

An ejector system is a device that uses a high-velocity fluid to draw in and mix with a secondary fluid or gas.

• Ejector systems work based on the Venturi effect, where a high-velocity fluid stream creates a low-pressure zone that draws in the secondary fluid or gas.

• They are commonly used in applications such as steam turbines, refrigeration systems, and vacuum systems.

• Ejector systems are efficient and reliable, with low...read more

The number of stages of turbine blades varies depending on the specific turbine design and application.

• Turbine blades are used in various applications such as gas turbines, steam turbines, and wind turbines.

• The number of stages in a turbine refers to the number of sets of rotating and stationary blades.

• Each stage of turbine blades helps to extract energy from the fluid passing through the turbine.

• Gas turbines typically...read more

The total number of bearings in a turbine varies depending on its design and size.

• The number of bearings in a turbine can range from a few to several dozen.

• The main purpose of bearings in a turbine is to support rotating components and reduce friction.

• Different types of bearings, such as ball bearings or roller bearings, may be used in a turbine.

• Large turbines, such as those used in power plants, typically have more be...read more

Steam enters the turbine at the high-pressure stage.

• Steam enters the turbine at the high-pressure stage to maximize energy extraction.

• The high-pressure steam is directed into the turbine blades, causing them to rotate.

• The steam then passes through multiple stages of the turbine, gradually losing pressure and expanding.

• At each stage, the steam's energy is converted into mechanical work to drive the turbine.

• Finally, the ...read more
