Constant Speed Control Switch - ANSWERS-safety
component.
Used when steady/constant demand for compressed air.
If demand drops excess compressed air is released through
pressure release valve.
Cooling system - ANSWERS-safety component.
compression chamber and compressed air must be cooled
to avoid overheating.
,Small compressors are air-cooled (fan).
Large compressors are water-cooled.
Low Oil Level Indicator Switch - ANSWERS-safety
component.
automatically shut down compressor if oil is low.
Serious damage can be caused if compressor is operated w/
low oil
Maintenance & Repairing Compressor- General
Requirements - ANSWERS--always follow guidelines
outlined by manufacturer.
Repair:
-always turned off
-electrical supply shutdown
-air drained
-made by qualified technician
, How do air compressors work - ANSWERS-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 - ANSWERS-Reciprocating
Air compressors are sometimes called - ANSWERS-air pumps
Air compressors can be powered by: - ANSWERS-(1) electric
motors;
(2) internal combustion engines; or
(3) steam turbines
Explosions & air compressors - ANSWERS-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.
