Innovassynth Technologies Mechanical Maintenance Officer Interview Questions and Answers

pH range measures the acidity or alkalinity of a solution, typically from 0 (acidic) to 14 (alkaline).

• pH 0-6: Acidic solutions (e.g., hydrochloric acid).

• pH 7: Neutral solutions (e.g., pure water).

• pH 8-14: Alkaline solutions (e.g., sodium hydroxide).

• pH affects chemical reactions, biological processes, and material properties.

The permissible drop for a reactor refers to the allowable decrease in reactor coolant flow or temperature during operation.

• Permissible drop is typically defined by safety regulations and operational guidelines.

• For example, in pressurized water reactors, a drop of 10-15% in coolant flow may be acceptable under certain conditions.

• Exceeding permissible drop can lead to overheating and potential safety hazards.

Alignment of pump coupling is done by using alignment tools and techniques to ensure proper alignment of the pump shaft and motor shaft.

• Use alignment tools such as dial indicators, laser alignment tools, or straight edges.

• Check and adjust the parallel and angular alignment between the pump shaft and motor shaft.

• Ensure that the coupling hubs are properly aligned and tightened to the shafts.

• Perform alignment checks after...read more
