Plastiblends India Senior Mechanical Maintenance Engineer Interview Questions and Answers

Cooling towers are used to remove heat from a building or industrial process by transferring it to the atmosphere.

• Cooling towers are used in HVAC systems to cool water that has been heated by air conditioning systems or industrial processes.

• They work by evaporating a small portion of the water to remove heat, which lowers the overall temperature of the remaining water.

• The cooled water is then circulated back into the s...read more

1 mtr = 1000 mm

• 1 meter is equal to 1000 millimeters

• To convert meters to millimeters, multiply by 1000

• For example, 2 meters is equal to 2000 millimeters

1 inch is equal to 25.4 millimeters.

• 1 inch = 25.4 mm

• To convert inches to millimeters, multiply by 25.4

• Commonly used conversion in engineering and construction

Reactors can be made of various materials depending on the application and requirements.

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

• It is possible that these terms are specific to a certain industry or company.

• Please clarify the question so that a proper answer can be given.

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
