What does the air displacement on the air compressor nameplate mean
air compressor nameplate on the "displacement" is what does that mean?
a word to understand
the displacement is how much compressed air this air compressor can "spit" out per minute.
You can think of it as the water outlet speed of a water pipe-the greater the displacement, the more compressed air the machine can produce per minute, and the more "vigorous" the work ".
For example, you will understand.
Suppose you take a big bucket to pick up the air from the air compressor:
- A large displacement machine & rarr; Can fill several large barrels in a minute
- machines with small displacement & rarr; Only one keg can be filled in one minute
the number written on the nameplate tells you: how much gas can this machine produce in a minute.
What is the relationship between water lubricated air compressor?
Now some air compressors use water lubrication technology that is, water is used instead of oil to participate in the compression work.
When working, water flows inside the machine to help seal between the rotors and take away heat. The entire compression process is completed by water.
then how to calculate its displacement?
Exactly the same reasoning.
Whether you use oil or water, the displacement is-- how much compressed air can this machine finally send out per minute. Water is just a way to help the machine complete the compression work, but the concept of "how much gas is produced in a minute" remains unchanged.
Why care about displacement?
| Your needs | how much displacement to choose |
|---|---|
| supply air to a small pneumatic tool | choose a small displacement is enough |
| at the same time to drive several equipment to work | choose a large displacement to move |
the choice is small & rarr; Not enough air, equipment "out of breath"
the choice is big & rarr; Waste of electricity, waste of money
simple summary
displacement = how much gas the air compressor can produce per minute
whether it is an air compressor lubricated with oil or lubricated with water, looking at the exhaust volume is equivalent to looking at the "air outlet speed" of the machine. The right choice is enough and not wasteful.
