The purpose of compressed air, what are the things of compressed air

Compressed air is very versatile.

Pumping compressed air into the tires of cars and bicycles not only supports the weight of the car body and all objects on the car, but also makes the driver and cyclist feel stable and comfortable. Cars, walls and furniture can be painted with paint mixed with compressed air in cans. Spraying unclean masonry buildings with compressed air can wipe off the dirt on the surface of the masonry.

In addition, compressed air is used in many places such as hovercraft, nail guns, control of car door switches, construction, medical care, etc.

3: Compressed air can be used to paint cars, walls and furniture.

1. It can make some mechanical driving gases, such as air drills and air picks.

2. It is compressible and can be used as filler; For example, basketball, 3 can store energy, and the compressed gas stored in the cylinder can push the piston to do work

1.OK. Short.

Gas springs. 2.It can be done.

Pressurized air. Cannon (issued.) Infrasound.

3.It can be used on submarines as an escape air bag.

All of you are right. But it's a little too professional, it's not **, it's just an essay. Of course, the concept of compressed air is like this.

I'm adding some use. Blow dust. Hey!

In wastewater treatment, compressed air can be used for air flotation and degreasing.

In the process of air flotation, the fine bubbles first adhere to the suspended particles in the water, forming an overall density smaller than that of the umbrella"Bubbles - particles"complex, so that the suspension'The particles float to the surface of the water along with the bubbles.

To achieve air flotation separation, the following three basic conditions must be met: first, a sufficient number of fine bubbles must be generated in the water; Second, the pollutants to be separated must be formed into insoluble solid or liquid suspensions; Third, the bubbles must be able to adhere to the suspended particles. The focus here is on the formation of fine bubbles and their adhesion to suspended particles.

First, the compressed air is dissolved into the water, and when the pressure is reduced, the tiny air cannon presides out of the liquid and brings the oil to the surface, which can remove the oil from the water.

The compressed air stuff is as follows:1. Liquefied gas.

Second, the glass factory blows the cylinder.

3. Explosives are discharged from the mine opening.

Fourth, the production of plastic plants.

5. Rocket launches.

Sixth, the ball cheers.

Principle of Ball Pumping:Compressed air is injected into the ball, and the more air you have, the harder the ball becomes; When compressed air is injected into the tire, the tire can bear a certain weight. On large cars, with compressed air switches.

doors and brakes; The hydraulic press uses compressed air to pressurize the water, and in the factory, the compressed air is used to start the air hammer to strike the iron; In coal mines, it can drill holes with a pickaxe. It is also used for pipelining the transport of liquids and granular objects.

Non-ferrous metal smelting and manufacturing: mainly used for power execution, instrument gas, spraying, etc. Rubber & Plastic Products:

It is mainly used for power execution, instrument gas, and plastic is also used in the blowing process. Aerospace industry: Because compressed air can not only withstand radiation and high temperature, but also withstand large acceleration speed, it has been widely used in the control of aircraft, rockets and missiles in modern times.

Military and chemical enterprises: It has been widely used in the transportation of chemical raw materials, the filling of harmful liquids, the packaging of explosives, and the automatic control devices of torpedoes. <

Transportation industry: the application of pneumatic devices such as brake brakes of trains, lane change devices of rails, opening and closing of vehicle doors and windows, automatic control of subways, automation equipment of ships, maintenance of aircraft, inflation of automobile hovercraft, loading and unloading of wharves, etc.

Compressed air plays an important role in spraying operations.

In the current spraying operation, compressed air is mainly used as the power source, not only in the whole process with compressed air and spraying paint mixture mixed and sprayed directly, but also compressed air as a protective measure directly applied to the artificial respiratory system.

In a working environment dominated by manual spraying, industrial compressed air is filtered by a filter device and supplied to the manual sprayer to breathe air while wearing a gas mask.

In order to ensure that the air is oil-free, the selected compressor must obtain ISO8573-1:2010 compressor "zero content" certification. A slight positive pressure should be maintained in the respirator mask to isolate the gas from the working environment of manual spraying operations, and also to prevent external dust, paint mist and volatile solvent gases from entering.

Compressed air, i.e. air that has been compressed by an external force. Air is compressible, and the air after the air compressor does mechanical work to reduce its volume and increase the pressure is called compressed air.

The characteristics of compressed air: clear and transparent, easy to convey, no special harmful properties, no danger, not afraid of overload, can work in many unfavorable environments.

Compressed air principle: air occupies a certain space, but it does not have a fixed shape and volume. When pressure is applied to the air in a closed container, the volume of the air is compressed, increasing the internal pressure.

When the external force is withdrawn, the air returns to its original volume under the action of internal pressure.

If there is an object in the container that can move, when the air returns to its original volume, the object will be pushed outward by the pressure of the air inside the container. This principle is widely used in production and life. For example:

When compressed air is injected into the tire, the tire can bear a certain weight.
