Thirumalai Chemicals Maintenance Engineer Interview Questions and Answers

A compressor is a mechanical device that increases the pressure of a gas by reducing its volume.

• Types of compressors include reciprocating, rotary screw, centrifugal, and scroll compressors

• Reciprocating compressors use pistons to compress gas

• Rotary screw compressors use two rotating screws to compress gas

• Centrifugal compressors use a rotating impeller to create high-velocity gas flow

• Scroll compressors use two interleav

There are three types of vessels entry: Confined Space Entry, Hot Work Entry, and Cold Work Entry.

• Confined Space Entry involves entering a space that is enclosed and has limited access points.

• Hot Work Entry involves entering a space where welding, cutting, or other heat-producing activities are being performed.

• Cold Work Entry involves entering a space where maintenance or repair work is being done that does not involve...read more

Blowers can be classified into centrifugal, positive displacement, and regenerative types. PM stands for Preventive Maintenance.

• Centrifugal blowers use centrifugal force to increase air pressure

• Positive displacement blowers use a mechanical means to trap and transport air

• Regenerative blowers use a rotating impeller to create air flow

• PM is a maintenance strategy that involves regular inspections and repairs to prevent e
