Compressor Fundamentals Flashcards
What does 0° rankine equate to in Fahrenheit
-460°F
what is Boyles law
P1xV1. P2xV2
——- = ——-
T1. T2
What does 0° Kelvin equate to in Celsius
-273°C
Two types of positive displacement compressors
Rotary
Reciprocating
How can you increase pressure in a compressor
Add a second stage
What opens and closes the reciprocating compressor valves
Pressure differential
What is the function of a crosshead and guides
The crosshead and guides keeps the piston rod straight thus allowing it to seal the pressure upon both sides of the piston
Can you have multi cylinders on the single stage compressor and if so what is it for
Yes for volume
What is the main purpose of an intercooler
Cooling the air with thus improving efficiency
What are the effects of high altitude on a compressor
The air is less dense that’s alarming to compressor to work easier but has to work longer to achieve the desired pressure
After coolers are used for what
To remove moisture after compression is completed
What three things that a receiver must have
The gauge
Drain
Safety relief valve
In a compressor system the pressure relief valve can be set no higher then
Lowest pressure reading of a part in the system
Define Clarence volume
The space between the piston and cylinder head
Define clearance pockets
With reciprocating compressors sometimes the capacity needs to be reduced The clearance pocket increases the clearance volume to reduce the compressors efficiency
