FDNY A-35 QUESTIONS AND ANSWERS
1. Air compressors are on occasion known as - ANSWER-air pumps
2. Air compressors can be powered via: - ANSWER-(1) electric powered vehicles;
(2) inner combustion engines; or
(3) steam mills
3. Air compressors allow... - ANSWER-(1) efficient restore of all styles of motors; and
(2) facilitate their safe operation on public thoroughfares
4. Air compressors strength... - ANSWER-(1) business device and (2) creation
equipment
5. Air consumption valve - ANSWER-safety component.
Fitted w/ an air clear out which prevents dust from being drawn into compression
cylinder. Dust within the compressor ought to bring about hearth in the cylinder
b/c of warmth inside the cylinder. Fire should case harm to air compressor.
This is why its essential to make sure clear out is constantly smooth and securely
linked to the compressor.
6. Air Reciever Operation - ANSWER-When air pressure reaches a sure stage, it forces
open a DISCHARGE VALVE (that's spring loaded). This releases compressed air
into air reciever (aka air tank), that's what supplies compressed air whilst wished.
7. As air is compressed it turns into - ANSWER-heated.
This is why in a multi degree air compressor there may be an intercooler between
stages of compressor.
8. Automatic Control Device - ANSWER-Attached to receiver.
Shuts down compressor whilst stress in receiver is ok and restarts whilst greater
pressure wanted.
9. CF Responsibility - ANSWER--visually investigate
-remain in place for a few minutes after compressor began
-do now not function at speeds above advocated ranged
10.Cleaning Compressor - ANSWER-most effective the use of cleaning soap and water
solution.
NEVER use benzene, kerosene or other mild oils for this reason. They might also
purpose an explosion when mixed w/ air under pressure.
Both oil and water can motive an explosion if they clearly input the compressor
tank.
11.Compliance w/ Lockout/Tagout - ANSWER-prevents a hundred and twenty fatalities
and 50,000 injuries every 12 months.
, Workers lose a mean of 24 workdays for restoration from exposure to dangerous
strength.
12.Compression Chamber operation - ANSWER-Air is compressed in compression
chamber which consists of a PISTON interior a CYLINDER. Piston moves up and
down.
When piston actions down -->attracts air into cylinder, thru INTAKE VALVE (valve
robotically opens while piston moves down).
When piston movements up-->air is compressed (intake vale routinely closes to
avoid air escaping from cylinder).
13.Constant Speed Control Switch - ANSWER-safety aspect.
Used while constant/consistent demand for compressed air.
If demand drops extra compressed air is released through pressure launch valve.
14.Cooling gadget - ANSWER-protection element.
Compression chamber and compressed air ought to be cooled to keep away from
overheating.
Small compressors are air-cooled (fan).
Large compressors are water-cooled.
15.Examples of device powered by air compressor - ANSWER-pneumatic wrenches, lifts
in vehicle provider stations, paint spray cubicles
16.Exception to unmarried stage/multi level distinction - ANSWER-CAVEAT: there are air
compressors with more than one pistons and cylinders that are unmarried degree
but those are best the ones where each cylinder discharges at once into air
receiver (in contrast to a real multi level air compressor).
17.Explosions & air compressors - ANSWER-If there's a building up of flammable gases
(ex: in provider stations and workshops), those gases are heavier than air and fall
to the ground earlier than spreading outward. These gases are without difficulty
ignited through sparks and high temperatures--which INCLUDES the heat
generated with the aid of an air compressor.
18.Filter & Moisture Separator Assembly (FMSA) - ANSWER-protection thing.
Moisture may be a problem; this filter out gets rid of moisture from compressed
air.
Installed between compressor and receiver.
Drain cock attached to FMSA to empty water and dust.
19.Heat & Compressor - ANSWER--never region flamable materials nearby;
