Air compressors power... - ANS>> (1) industrial equipment and
(2) construction tools
Examples of equipment powered by air compressor - ANS>>
pneumatic wrenches, lifts in auto service stations, paint spray
booths
Air compressors enable... - ANS>> (1) efficient repair of all
types of vehicles; and (2) facilitate their safe operation on public
thoroughfares
Permit is required for air compressor - ANS>> that compresses
air above 100 PSI
Types of air compressors - ANS>> (1) reciprocating;
(2) centrifugal;
(3) solar; and
(4) rotary
*Difference is the way in which they compress air
How do air compressors work - ANS>> 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 - ANS>> Reciprocating
Air compressors are sometimes called - ANS>> air pumps
Air compressors can be powered by: - ANS>> (1) electric
motors;
(2) internal combustion engines; or
(3) steam turbines
Explosions & air compressors - ANS>> 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 - ANS>> 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 - ANS>> 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
