What's the use of an air compressor?. Where can I use an air compressor?
The air occupies a certain space, but it has no definite shape and volume. When the pressure is applied to the air in the closed container, the volume of the air is compressed and the internal pressure is increased. When the external force is withdrawn, the air will recover to its original volume under the influence of internal pressure. If there is a movable object in the container, when the air returns to its original volume, the object will be pushed out by the pressure of the air in the container. This principle is widely used in production and life. For example: the ball into the compressed air, the more gas, the harder the ball; the tire into compressed air, the tire can bear a certain weight. In a large car, with compressed air brake and door switch; compressed air to water pressurized by the hydraulic pressure machine in the factory, the compressed air is used to drive the hammer blacksmith; in the coal mine, it can use hammer drilling. Compressed air is also used to transport liquids and granular objects in pipes.
Low pressure (several thousand PA) are mainly combustion supporting, such as boiler blowers, wind, replacement, such as checking containers, cooling, such as summer fans.Compressed air has a very wide range of uses. Moving compressed air into the tires of cars and bicycles can not only support the weight of the car body and all the objects on the car, but also make the driver and cyclist feel smooth and comfortable. Paint in cars, walls, and furniture can be painted with paint mixed with compressed air in cans. The use of compressed air to spray clean masonry buildings can wipe away the dirt on the bricks and stones. In addition, compressed air is used in many places, such as hovercraft, nail gun, car door switch control, building and medical treatment.
High pressure is mainly industrial applications.(1) air separation, used in the preparation of high concentration oxygen (combustion and chemical reactions), nitrogen (protective agents and raw materials).(2) as an air source for air transportation.(3) directly as a raw material in the nitrogenous fertilizer industry.(4) the air source (4-7MPa) of the industrial control institution.(5) the power of pneumatic tools (such as picks)
