Pumps can be classified based on their casings as follows: volute casing, axial split casing, and radial split casing.

• Volute casing pumps have a spiral-shaped casing that gradually expands to the discharge outlet.

• Axial split casing pumps have a casing split along the horizontal centerline of the pump.

• Radial split casing pumps have a casing split along the vertical centerline of the pump.

Air compressor works by compressing air to increase its pressure and decrease its volume.

• Air is drawn into the compressor through an intake valve.

• The air is then compressed using a piston or rotating impeller.

• Compressed air is stored in a tank or released directly for use.

• Examples of air compressors include reciprocating, rotary screw, and centrifugal compressors.

Control system is a system that manages, commands, directs or regulates the behavior of other devices or systems.

• Control system is used to manage and regulate the behavior of other devices or systems

• It involves the use of sensors, actuators, and controllers to maintain a desired output

• Examples include HVAC systems, traffic lights, and industrial automation systems

• Process control is a type of control system that is used...read more
