Chakr Innovation ITI Electrician Interview Questions and Answers

The hydraulic system is a technology that uses liquid to transmit power.

• Uses incompressible fluid to generate force

• Consists of a pump, fluid reservoir, valves, cylinders, and motors

• Commonly used in heavy machinery like excavators and hydraulic presses

Backlash is the clearance or lost motion between mechanical components, typically in gears or threads.

• Backlash is the amount of free movement or play between components in a mechanical system.

• It can be found in gears, threads, or any other mechanical connection where there is a gap between mating parts.

• Backlash can affect the accuracy and precision of a mechanical system.

• It is important to minimize backlash in precisio...read more

Why-why Analysis is a problem-solving technique that involves asking 'why' multiple times to get to the root cause of an issue.

• Involves asking 'why' repeatedly to uncover the underlying causes of a problem

• Helps in identifying the root cause of an issue rather than just addressing symptoms

• Commonly used in quality management and process improvement

• Example: If a machine breaks down - Why? Because a part failed - Why? Beca...read more

Backlash in axis refers to the clearance or play between mating components in a mechanical system.

• Backlash is the amount of movement or play between components in a mechanical system.

• It can affect the accuracy and precision of the system.

• Backlash can be minimized by using precision components or adjusting the system properly.

• For example, in a gear system, backlash can cause inaccuracies in positioning if not properly a

There are several types of bearings used in mechanical applications.

• Plain bearings

• Rolling element bearings (ball bearings, roller bearings)

• Thrust bearings

• Sleeve bearings

• Needle bearings

• Tapered roller bearings

• Spherical roller bearings

There are several types of hydraulic pumps, including gear pumps, vane pumps, piston pumps, and screw pumps.

• Gear pumps are simple and economical, but not very efficient.

• Vane pumps are more efficient and quieter than gear pumps.

• Piston pumps are highly efficient and can handle high pressures.

• Screw pumps are used for high viscosity fluids and can handle high pressures as well.
