Kirloskar Group Interview Questions, Process, and Tips

Pumps are used to move fluids or gases from one place to another.

• Pumps are used in various industries such as water treatment, oil and gas, and manufacturing.

• They can be used to transfer liquids, create pressure, or circulate fluids.

• Examples include centrifugal pumps, diaphragm pumps, and vacuum pumps.

I am familiar with pumps through my experience managing inventory and equipment in previous roles.

• Managed inventory of pumps in previous job

• Coordinated maintenance and repairs for pumps

• Trained staff on proper use and maintenance of pumps

Frictional loss in pump refers to the energy lost due to friction between the moving parts of the pump.

• Frictional loss increases with higher flow rates and viscosity of the fluid being pumped.

• It can be reduced by using smoother surfaces, proper lubrication, and minimizing bends in the piping system.

• Examples of pumps where frictional loss is a concern include centrifugal pumps and positive displacement pumps.

CNC works on a computer numerical control system.

• CNC machines are controlled by a computer program that dictates the movement and operation of the machine.

• The system uses numerical data to control the cutting tools and other machinery in the manufacturing process.

• Examples of CNC machines include milling machines, lathes, and laser cutters.

Armature reaction refers to the effect of the magnetic field produced by the armature current on the main magnetic field of a DC motor.

• Armature reaction causes distortion in the main magnetic field of the DC motor

• It leads to a shift in the neutral plane of the motor

• Compensating windings are used to counteract the effects of armature reaction

• Armature reaction can affect the performance and efficiency of the motor
