Introduction to air compressor 1000769549

Basic principle
Positive displacement compressor: Increases gas pressure by directly changing gas volume, such as reciprocating compressor, which relies on the reciprocating motion of the piston in the cylinder to compress gas; rotary compressor achieves compression through the forced motion of rotating elements, including sliding vane compressor, liquid piston compressor, twin-rotor compressor, screw compressor, etc.
Speed ​​compressor: Uses high-speed rotating blades to convert the kinetic energy of gas molecules into gas pressure energy, thereby increasing the pressure of compressed air, such as centrifugal compressor, axial flow compressor, mixed flow compressor, etc.
 

Purpose of air compressor 1000769549
1. Providing power: Compressed air can be used as a power source to drive various pneumatic machinery and tools, such as rock drills, pneumatic picks, pneumatic wrenches, etc. It is also widely used in instrument control and automation devices, vehicle braking, door and window opening and closing, etc.
2. Gas transportation and storage: Used for pipeline transportation and bottling of gas, such as long-distance coal gas and natural gas transportation, and filling of oxygen cylinders, acetylene cylinders, etc.
3.Refrigeration and gas separation: Gas can be liquefied after being compressed, cooled, and expanded by an air compressor and used for artificial refrigeration; if the liquefied gas is a mixed gas, the components can also be separated in the separation device to obtain qualified Various gases of different purity, such as pure oxygen and pure nitrogen can be obtained by liquefying and separating air.
4. Industrial production: In the chemical, petroleum, metallurgy, mining and other industries, air compressors provide the high-pressure gas required for chemical reactions to promote the progress of chemical reactions. They are also used for oil well fracturing, high-pressure air blasting coal mining, metal smelting and other operations.
5. Other fields: such as the use of compressed air to stir slurry in the food and pharmaceutical industries, the use of compressed air to blow weft yarn in jet looms, as well as the sinking and floating of submarines, salvaging of sunken ships, submarine oil exploration, hovercraft, tire inflation, spray painting, bottle blowing machines, air separation industries, the production of high-pressure air for cooling and drying of processed parts, etc.
