Air compressors power...
(1) industrial equipment and (2) construction tools
Types of air compressors
(1) reciprocating;
(2) centrifugal;
(3) solar; and
(4) rotary
*Difference is the way in which they compress air
How do air compressors work
take the air in a room and force it into a container UNDER PRESSURE. The more
air forced into the container, the greater the pressure. Compressed air can be
discharged from the container at a controlled rate.
Most common air compressor
Reciprocating
, Air compressors are sometimes called
air pumps
Air compressors can be powered by:
(1) electric motors;
(2) internal combustion engines; or
(3) steam turbines
Explosions & air compressors
If there is a build up of flammable gases (ex: in service stations and
workshops), those gases are heavier than air and fall to the floor before
spreading outward. These gases are easily ignited by sparks and high
temperatures--which INCLUDES the heat generated by an air compressor.
To avoid explosions w/ air compressors
Raise air compressor at LEAST 5 feet above ground level so that no
flammable gases are drawn into the compressor. To meet the height
requirement you can place
compressor on a shelf or bench OR the air receiver tank may be turned and
stood on end w/ the air compressor bolted to the top of the tank.
Power to air compressor
entire unit is driven by an electric motor. Motor activates a series of drive
belts. Belts power the moving parts of the unit--like w/ power steering and
alternator in
automobile
