Lloyds Metals And Energy Assistant Manager Interview Questions and Answers

Motor protection settings are parameters set to protect the motor from damage due to overcurrent, overload, overheating, etc.

• Motor protection settings include overload relay, thermal overload relay, circuit breaker, fuses, etc.

• These settings are crucial for preventing motor damage and ensuring safe operation.

• Examples of motor protection settings include setting the overload relay to trip at a certain current level, set...read more

A gear box is a mechanical device that uses gears to provide speed and torque conversions from a rotating power source to another device.

• Gear boxes are commonly used in vehicles to transfer power from the engine to the wheels.

• They can also be found in industrial machinery to control speed and direction of rotation.

• Gear boxes consist of multiple gears of different sizes that mesh together to provide the desired output.

• T...read more

Types of pumps include centrifugal, positive displacement, and axial flow pumps.

• Centrifugal pumps use a rotating impeller to increase the pressure of a fluid.

• Positive displacement pumps move fluid by trapping a fixed amount and forcing it through the discharge.

• Axial flow pumps move fluid parallel to the impeller shaft.

• Examples include centrifugal pumps in HVAC systems, diaphragm pumps in chemical processing, and axial

Blast furnace is a metallurgical process used to extract iron from its ore through reduction reactions.

• Iron ore, coke, and limestone are fed into the furnace

• Hot air is blown into the furnace to ignite the coke and initiate the reduction process

• The iron ore is reduced to molten iron, which is tapped off at the bottom of the furnace

• Slag, a byproduct of the process, is also tapped off and used in construction

• The process i...read more

Turbocharger increases the power output of the engine in a mechanical shovel.

• Turbocharger compresses the air entering the engine, allowing more fuel to be burned and increasing power output.

• It helps the shovel to work more efficiently and effectively.

• Without a turbocharger, the engine would need to be larger and heavier to produce the same amount of power.

• Turbochargers are commonly used in heavy machinery like excavato

Blast furnace operation involves the process of smelting iron ore to produce iron.

• Blast furnace is a large structure used to extract iron from iron ore.

• The process involves heating iron ore with coke and limestone in a continuous flow of hot air.

• The intense heat melts the iron ore, separating the impurities and producing molten iron.

• The molten iron is then tapped from the bottom of the furnace and further processed for...read more
