Plant Machinery Engineer Interview Questions and Answers

Engines typically use engine oil as a lubricant, which is circulated through the engine by a pressurized lubrication system.

• Engines typically use engine oil as a lubricant to reduce friction between moving parts

• The lubrication system in engines includes components such as oil pumps, oil filters, and oil passages

• There are different types of lubrication systems such as splash lubrication, pressure lubrication, and dry sump lubrication

• Examples of engine lubricant brands include ...read more

Turbocharger, intercooler, cooling system, and lubrication system are components used in machinery to enhance performance and efficiency.

• Turbocharger is a device that increases the efficiency and power output of an engine by forcing extra air into the combustion chamber.

• Intercooler is used to cool the compressed air from the turbocharger before it enters the engine, increasing its density and performance.

• Cooling system helps regulate the temperature of the engine to prevent o...read more

A broken conveyor belt can be jointed using various methods depending on the type of belt and the extent of damage.

• Assess the extent of damage and determine the appropriate jointing method.

• Clean the damaged area and remove any debris or contaminants.

• Apply adhesive or vulcanizing solution to the damaged area and the replacement patch.

• Position the patch over the damaged area and apply pressure to ensure a strong bond.

• Allow the joint to cure according to the manufacturer's instr...read more
