Power Mech Projects Mechanical Engineer Interview Questions, Process, and Tips

A lathe is a machine tool that rotates a workpiece about an axis of rotation to perform various operations such as cutting, sanding, drilling, knurling, or deformation.

• Lathe is used to shape and cut materials such as wood, metal, and plastic.

• It rotates the workpiece on its axis and a cutting tool is applied to the workpiece to remove material.

• Lathe can perform various operations such as turning, facing, drilling, borin...read more

Boiler drum is a cylindrical container which is used to store water and steam produced in a boiler.

• It is a vital component of a boiler system.

• It is usually made of steel and is located at the top of the boiler.

• It acts as a reservoir of water/steam and helps to separate steam from water.

• It also helps to regulate the pressure and temperature of the steam.

• The level of water in the drum is maintained by a feedwater control...read more

Types of gear boxes and gears commonly used in mechanical engineering include spur gears, helical gears, bevel gears, and worm gears.

• Spur gears: most common type, straight teeth parallel to the gear axis

• Helical gears: angled teeth for smoother and quieter operation

• Bevel gears: used to change the direction of rotation

• Worm gears: used for high reduction ratios and high torque applications

Types of conveyors include belt, roller, chain, screw, and pneumatic. Maintenance involves regular inspection, cleaning, lubrication, and replacing worn parts.

• Types of conveyors: belt, roller, chain, screw, pneumatic

• Maintenance tasks: regular inspection, cleaning, lubrication, replacing worn parts

• Examples: Belt conveyor used in manufacturing plants, roller conveyor in warehouses

Troubleshooting blowers and compressors involves identifying and resolving issues with their operation.

• Start by checking for any unusual noises or vibrations coming from the blower or compressor.

• Inspect the filters and ensure they are clean and not clogged, as this can affect performance.

• Check for any leaks in the system, as this can lead to a decrease in efficiency.

• Verify that all connections and components are secure...read more

Overhauling gear boxes and fans compressors involves disassembling, inspecting, repairing, and reassembling the components to ensure optimal performance.

• Disassemble the gear boxes and fans compressors carefully to inspect for any wear or damage

• Replace any worn out or damaged parts with new ones

• Clean and lubricate all components before reassembling

• Perform tests to ensure proper functioning after overhaul

• Document the ove
