What can an air compressor do? A full story

let's take an example first.

You can think of an air compressor as a factory "Lungs".

People breathe by the lungs and send oxygen to the whole body; factories rely on air compressors to "breathe" and send compressed air to every corner. Where strength is needed, where blowing is needed, and where control is needed, there is compressed air.

It is not exclusive to a particular industry, basic equipment that is inseparable from almost all industries..

1. to the equipment "hard"-power source

this is the most common usage. Compressed air is like an invisible hand, which can push, pull, twist and clamp.

• Pneumatic wrench: It is very fast to turn screws. Automobile factories and furniture factories rely on it.
• Pneumatic clamp: Clamp the workpiece so hard that it will not deviate during processing.
• Pneumatic valve: The switch in the pipeline is pushed by gas, and the response is very fast.
• Cylinder: Push things straight, simple, durable, not afraid of blocking

why not use electricity to drive it? Because compressed air soft strength, no overshoot, touching things will not damage the delicate workpiece. Moreover, pneumatic tools are much lighter than electric tools, and workers are not tired after taking them for a day.

2. blow things away-cleaning and conveying

compressed air is the most "silly and rough" usage, but it is also the most inseparable.

• Soot blowing and chip blowing: After the machine is finished, iron filings, dust and slag will be blown away by a stream of air.
• Blow-dry: After the parts are washed, blow dry with air, ten times faster than wiping with cloth
• material conveying flour mills, cement factories, pharmaceutical factories, powdery things are blown by air, from one workshop to another, and the pipes are connected.

When you go to the flour mill, the whole workshop is white. The flour is "blown" from the mill to the packaging machine by compressed air, and there is no need to move it.

3. help process "play with"-control and auxiliary

many production processes do not rely solely on brute force, but also require fine coordination. Compressed air is a "supporting role" here ".

• Paint spray gun: Mist the paint and spray it evenly on the surface of the product. Cars, furniture, and mobile phone cases all rely on this
• spraying dry powder: Give a layer of protective film on the metal surface to prevent corrosion and rust
• pneumatic stirring: In the chemical reaction kettle, gas is used to stir, which is more uniform than mechanical stirring and is not afraid of corrosion.
• bubbling aeration: In the sewage treatment plant, cheer up the water and let the dirt in the water be "eaten" by microorganisms"

especially the painting, the compressed air cleanness directly determines the quality of paint. If a little oil or water is mixed in the gas, the sprayed paint will have shrinkage and blistering, and the whole batch of products will be scrapped.

4. brakes and safety-life-saving work

• train brake: Have you ever been on a train? The train brakes rely on compressed air, and as soon as you step on the brakes, the air puts the brake shoes on the wheels, and the car stops.
• mine ventilation: The fresh air breathed by underground miners is brought in by air compressors.
• Airbag: The one that pops up to protect you when the car collides, and the compressed air is released instantly behind it.

There is no room for any mistakes in these places, so the air compressor high reliability requirements-- Can't stop, can't break, can't oil.

5. refrigeration and cooling-invisible air conditioning

compressed air becomes cold when it expands, and this principle is used in many places:

• equipment cooling: When cutting, the tool heats up, and when a stream of air blows over, it will cool down.
• Environmental cooling: In some high-temperature workshops, it is much cheaper to use compressed air for local cooling than to turn on the air conditioner.
• Instrument air cooling: The precision instrument in the factory relies on compressed air to dissipate heat to ensure accurate readings

6. special industry-I can't do without it.

Some industries to the air requirements to the "abnormal" degree, but it is inseparable from the compressed air.

Food Industry

bread fermentation needs gas to stir, packaging needs gas to blow, filling needs gas to push. But the food is most afraid of oil and dirty things mixed in, so must use compressed air clean enough to drink.

Pharmaceutical industry

tablets, capsule filling, liquid delivery, all by pneumatic equipment. But the drug can not have any pollution, the air in the oil mist, bacteria, particles are taboo.

Electronic industry

as mentioned earlier in chip manufacturing, hundreds of processes cannot be separated from compressed air, and require cleaner than the operating room..

Textile Industry

the shuttles of the loom fly around on compressed air. One loom uses a lot of gas in a minute, and hundreds of looms in the whole workshop run at the same time, which is frightening.

Why are water-lubricated air compressors becoming more and more popular in these scenes?

You may have found that many of the above scenes have a common pain point: the air cannot be dirty..

Traditional air compressor by oil lubrication, no matter how good the seal, a long time there will always be a trace of oil running into the air. Just like your range hood, no matter how good it is, there will be a little smoke running out.

And water-lubricated air compressor from the root to solve this problem:

• lubrication is with water, not oil therefore, there is no oil mist in the compressed air, and the cleanliness level is directly increased to a higher level.
• Water will not age deterioration the oil of the traditional air compressor will become sticky, sour and produce sludge after being used for a long time. Water does not have this problem at all, and the quality of the air will be the same after being used for three years and five years.
• Water can also help to dissipate heat, The heat generated during the compression process is directly taken away by water, the machine is not easy to burn, the efficiency is higher, and the electricity consumption is less
• no waste oil to dispose, The traditional air compressor needs to change the oil several times a year, and the waste oil has to be treated at a cost. For water lubrication, only normal water supply is required, and maintenance is much simpler.

For food, medicine, electronics and other industries with high air quality requirements, water lubricated air compressors are simply "tailor-made"-- the air coming out is clean, the machine itself is also worry-free, and the filtering equipment at the back can be installed several times less.

No oil and water lubrication air compressor is suitable for where?

There is another way to go without oil and water lubrication-- simply without any lubricating medium, Relying on precise mechanical structure and special materials, the rotors can rotate without contact or friction.

Its benefits are:

• there is neither oil nor water in the air, clean to the extreme
• behind the dry burden is particularly light because the water content of the gas itself is very low
• especially suitable for occasions that are also sensitive to moisture, such as the production of certain precision electronic components.

Water lubrication and oil-free water lubrication are like two roads, one with water and one without anything, but the destination is the same: let the compressed air work cleanly.

One sentence summary

there are countless uses for air compressors-hard work, soot blowing, painting, braking, ventilation, cooling, transportation, and almost every industrial scene you can think. And the higher the air quality requirements, the more water-lubricated air compressors and oil-free water-lubricated air compressors can be used-- keep oil and dirt out of the door from the source, so that every wisp of compressed air is clean and complete its mission.
