hot hose on compressor

updated thu 9 oct 08

 

Dolita Dohrman on sat 27 sep 08


I was using my pancake compressor the other day to spray about 10
bowls. It may have always been this way but I noticed that the hose
connecting the motor to the compressor was very hot. I was able to
touch it but not for long. Is this normal? I refer to the black box
on top of the compressor as the motor, perhaps that is the wrong
terminology but I hope you know what I mean.
Dolita - where it is hot and dry in Kentucky. We just went through
the remnants of Hurricane Ike without one drop of water but 75 mile
an hour winds. Ripped up Louisville pretty good. Compared to what
Ike did to other areas though, we can't complain.

Dolita dear...
Someone taught you wrong!

Pancakes do not need compressing. They cook that way naturally.
You might use a meat tenderizing mallet on them if they're thicker than
you like,
or simply run them over with the car.

I just give them a good whack with a 2X4, while Joe and the dogs run for
cover.
ROFL,
Wayne Seidl

Dolita,

I don't know what causes it, but my compressor does the same thing. My
brother lives down in the St James area and had trees down and no
electricity for a while. We didn't have much in Berea. I was at my
Mother's house in Lexington that day and they had some high winds, but
not much damage.

I'm guessin' that when you say "compressor," you are referring to the
flat-ish (hence "pancake") air tank on the bottom of the unit. And
that "black box" on top contains the motor and the compressor it drives.

It is normal that the hose (or tube) connecting the motor/compressor
to the tank will be hot--very hot!

The technical explanation is that air is claustrophobic and does not
like to be confined in small places. It becomes quite
hot-under-the-collar when forced to do so!

Hi Dolita,



When Air is compressed, heat results...

Air Compressors typically get quite hot around the Cylinder Head, and so
anything connected to the Cylinder Head will be conducting the heat also.

On small outfits such as yours, the fittings for the outlet Hose maybe close
enough to the Cylinder Head for it to get fairly warm.

Dolita,
all gases get hot when compressed.
The ideal gas law expresses it as a formula:
PV=nrT
where:
P stands for pressure
V stands for volume
n stands for the number of moles of gas present
r stands for the "ideal gas constant" ( a factor
used to make the calculations work)
T stands for the temperature in degrees Kelvin.
In a compressor, we increase P ( pressure) by
shoving more and more n ( moles of air) into a
tank of fixed size. Solving for T illustrates that
as a gas is compressed, its temperature rises.
Thus, there is nothing wrong with your compressor.

Thanks to all my buddies who responded. Learned a little something
new. Sorry I did not get back to y'all sooner but there is a little
rain in my life right now.
Dolita - in Louisville, where we did indeed get some rain last night,
finally!
