Sambandam Spinning Mills Interview Questions and Answers

An internal combustion engine (IC engine) is a heat engine where the combustion of fuel occurs inside the engine.

• IC engines are commonly used in vehicles, generators, and other machinery.

• They convert chemical energy into mechanical energy through combustion.

• There are two main types of IC engines: spark-ignition engines (petrol engines) and compression-ignition engines (diesel engines).

Engine cooling in CI engines is essential to maintain optimal operating temperatures and prevent overheating.

• Ensure proper circulation of coolant throughout the engine

• Regularly check coolant levels and quality

• Monitor engine temperature using gauges

• Clean and inspect radiator for any blockages

• Consider using additives to improve cooling efficiency

CI engine uses coolant circulation for cooling, while IC engine is where fuel burns inside the cylinder.

• CI engine cools through coolant circulation in engine case and radiator

• IC engine is where fuel burns inside the cylinder

• Coolant exchange helps in dissipating heat from the engine

AC motors are classified into different types based on their construction and operation, such as induction motors, synchronous motors, and brushed DC motors.

• Induction motors are the most commonly used type of AC motor and work on the principle of electromagnetic induction.

• Synchronous motors operate at a constant speed determined by the frequency of the AC power supply.

• Brushed DC motors use brushes and a commutator to s...read more

Transformer works on the principle of electromagnetic induction to transfer electrical energy between two or more circuits.

• Transformers have two coils - primary and secondary, which are magnetically coupled.

• When an alternating current flows through the primary coil, it creates a changing magnetic field.

• This changing magnetic field induces a voltage in the secondary coil, transferring electrical energy.

• Transformers are ...read more

A transformer is a device that transfers electrical energy between two or more circuits through electromagnetic induction.

• Transformers work on the principle of electromagnetic induction

• They consist of primary and secondary coils wound around a core

• Step-up transformers increase voltage while step-down transformers decrease voltage

• Efficiency of a transformer is determined by its core material and design

Heat exchangers are devices used to transfer heat between two or more fluids, without them mixing together.

• There are three main types of heat exchangers: shell and tube, plate, and finned tube.

• Shell and tube heat exchangers consist of a shell with tubes running through it, allowing one fluid to flow through the tubes while another flows over the tubes.

• Plate heat exchangers use plates to separate the fluids and transfer...read more

Distillation is a process used to separate components of a liquid mixture based on their boiling points.

• Types of distillation include simple distillation, fractional distillation, and steam distillation.

• Simple distillation is used to separate components with a large difference in boiling points.

• Fractional distillation is used for components with closer boiling points, using a fractionating column to achieve better sepa...read more
