Sodexo Mechanical Technician Interview Questions and Answers

Main parts of a pump include impeller, casing, shaft, bearings, and seals.

• Impeller: Rotating component that generates the flow of fluid.

• Casing: Encloses the impeller and directs the flow of fluid through the pump.

• Shaft: Transfers the rotational energy from the motor to the impeller.

• Bearings: Support the shaft and reduce friction.

• Seals: Prevent leakage of fluid at the shaft.

The play of ball nut refers to the amount of axial movement allowed between the ball nut and the screw in a ball screw mechanism.

• Play of ball nut is important for ensuring smooth operation and preventing binding in the ball screw system.

• It is typically specified by the manufacturer and should be within a certain tolerance range.

• Excessive play can lead to backlash and reduced precision in the system.

Machine geometry is achieved by ensuring precise measurements and alignments of components to meet design specifications.

• Use precision measuring tools such as calipers, micrometers, and dial indicators to measure dimensions accurately.

• Check and adjust alignments of components using alignment tools like straight edges and squares.

• Follow design specifications and tolerances closely to ensure proper machine geometry.

• Perfo...read more
