Air compressor flow is what meaning

sentence explanation

the air compressor flow rate is how much gas this machine can spit out per minute. You can understand it as the water output of the faucet, but it is not water, but compressed air.

Traffic Two Common Sayings

the first is called free air flow, which is how much volume of air the machine sucks in, compresses and spits it out. Because the volume of air becomes smaller after it is compressed, the amount spit out looks less than the amount sucked in, but the actual work ability is the same. This statement is more true and can reflect the actual working ability of the machine.

The second type is called exhaust flow, which is how much compressed air the machine spits out. This number will vary depending on the degree of compression, so looking at this number alone can sometimes make people confused about how powerful the machine is.

Traffic in the end with what relationship

the size of the flow is mainly related to three things.

The first is the size of the internal rotor or piston of the machine. Just like you drink water with a thick straw and drink water with a thin straw, a thick straw can suck up more water in a minute. The same is true for air compressors. The larger the internal space, the more air can be processed per minute.

The second is how many revolutions the machine makes per minute. The faster you turn, the more air you swallow and the more natural you spit out.

The third is the degree of compression. The more compressed, the smaller the volume of gas that appears to be, but the actual amount of air contained is the same. Therefore, when looking at the traffic, it is necessary to find out under what conditions it is measured.

traffic is large?

many people think that it is always right to choose a larger flow, but this is not the case. The flow selection is too large, and the machine is often in a state of insufficient food, just like asking a Hercules to move a feather, which wastes electricity and the machine is prone to problems.

Moreover, the frequency of starting and stopping the air compressor with excessive flow will become very frequent, which is not good for the life of the machine.

traffic is small?

the smaller the traffic selection, the more troublesome it will be. Your equipment needs 30 liters of gas per minute. As a result, the air compressor can only produce 25 liters per minute. Then there will be insufficient gas supply.

It shows that the equipment moves slowly, the cylinder thrust is not enough, and the pneumatic tools cannot turn. In severe cases, the machine will always run at full capacity, with severe fever and a rapid shortening of life.

How do you calculate how much traffic you need?

the simplest way is to add up all the equipment that uses gas. For example, if you have three cylinders, the first one needs ten liters per minute, the second needs eight liters, and the third needs twelve liters, which adds up to 30 liters per minute.

Then leave some more margin on this basis, because the pipeline will be lost, the joint may leak, and the equipment cannot run at full load all the time. Generally, it is enough to leave more than 20% to 30%.

Water lubricated air compressor flow has what special place

when the air compressor is lubricated with water, the concept of flow is actually the same, but there are some places that need attention.

The water-lubricated air compressor uses water instead of oil for lubrication and sealing, and its internal operation mode is somewhat different from that of ordinary machines. The lubrication effect of water and oil is not the same, so in the same volume, the actual air efficiency of water-lubricated air compressor may be slightly different from ordinary machines.

However, this does not mean that the flow rate of the water-lubricated air compressor is not allowed, but that when you calculate the amount of flow you need, you should take the free air flow rate actually marked by the water-lubricated air compressor as the standard, and do not take the experience of ordinary machines.

In addition, during the working process of the water-lubricated air compressor, the water will take away part of the heat generated by the compression, and the machine will run more smoothly. This smoothness makes its flow output more uniform, not as big and small as some machines. For those occasions that require high gas stability, this characteristic of water lubricated air compressor is an advantage.

One more important point. The gas produced by the water-lubricated air compressor does not contain oil, so you can be a little easier when calculating the burden of subsequent filtration and drying equipment. Because there is no oil to deal with, the efficiency of the entire gas system will be higher, and the actual amount of gas reaching the gas consumption point will be closer to the nominal flow rate of the air compressor.

A confusing place

many people confuse flow and pressure. The flow rate is how much gas is produced per minute, and the pressure is how tight the air pressure is. These two are completely different things.

For example, the flow is like the thickness of a water pipe, and the pressure is like how tight the faucet is. No matter how thick the water pipe is, there is no water coming out when the faucet is turned off. No matter how big the faucet is, the water pipe is too thin to produce much water.

Therefore, when selecting an air compressor, both the flow rate and the pressure should be seen, which is indispensable. Just look at the flow without looking at the pressure, or just look at the pressure without looking at the flow, will choose the wrong machine.

To sum up

the flow rate of the air compressor is how much compressed air can be produced per minute, which is the core reference when selecting the machine. When calculating, add up the requirements of all the gas-using equipment and leave some margin. If the air compressor is lubricated with water, its flow output is more stable, the output gas is cleaner, and the actual efficiency of the whole system will be higher. If you know what traffic means, you won't be confused by various numbers when choosing a machine.
