Plant Technician Interview Questions and Answers

A reciprocating compressor or pump is a type of machine that uses a piston to compress gas or liquid.

• Reciprocating compressors and pumps use a piston to compress gas or liquid.

• The piston moves back and forth inside a cylinder to create pressure.

• These machines are commonly used in refrigeration, air conditioning, and oil and gas industries.

• Examples include reciprocating air compressors, reciprocating refrigeration compressors, and reciprocating pumps for water or oil.

The Haber process for ammonia production requires a temperature of 450°C and a pressure of 200 atmospheres.

• The temperature required for the Haber process is 450°C.

• The pressure required for the Haber process is 200 atmospheres.

• These conditions are necessary for the reaction to occur efficiently.

• The high pressure helps to increase the yield of ammonia.

• The high temperature helps to speed up the reaction rate.

Reciprocating pumps use a piston or plunger to move fluid, while centrifugal pumps use a rotating impeller to create a flow.

• Reciprocating pumps are better suited for high-pressure, low-flow applications.

• Centrifugal pumps are better suited for low-pressure, high-flow applications.

• Reciprocating pumps are more efficient at handling viscous fluids.

• Centrifugal pumps are more efficient at handling low-viscosity fluids.

• Examples of reciprocating pumps include piston pumps and diaphra...read more

Working principles in lathe machine

• Lathe machine operates on the principle of rotating the workpiece against a cutting tool.

• The workpiece is held in a chuck or a spindle and rotated at a desired speed.

• The cutting tool is held in a tool post and moves along the workpiece to remove material.

• The cutting tool can be fed manually or automatically to achieve the desired shape and size.

• Lathe machines can perform various operations like turning, facing, drilling, boring, etc.

• The spee...read more
