Introduction of air compressor
1. What is an air compressor
An air compressor is a machine that produces compressed air by compressing a gas. Typically, a compressor can compress air to 0.1 MPa (about 1.0 kgf/cm2) or higher. (Reference: Products with discharge pressures less than 10 kPa are called fans, and those with discharge pressures between 10 kPa and 0.1 MPa are called blowers.)
The typical place for compressors is factories, and it is no exaggeration to say that almost all factories use compressors. It is widely used to drive products such as machine tools and presses, as a power source for various manufacturing processes, etc. For example, for metalworking-only machine tools, air compressors are also used for various purposes: tool removal, chip discharge, driving tool change rotation and mechanism spindle rotation, etc.
When the supply of compressed air stops, the plant production will also stop, so the compressor is also compared to the “heart of the plant” and plays a very important role in the production site.
2. Types of air compressors
First of all, the compression method of air compressors can be broadly divided into volumetric and turbine types. Volumetric is a type of compression in which the gas is confined to a fixed space and the volume is reduced by an external force to obtain pressure.
The turbine type is a compression method that gives the flow rate to the gas and converts the flow rate into pressure. The volumetric type can be divided into the reciprocating type and the rotary type.
The reciprocating type is suitable for obtaining high-pressure air, while the turbine type is suitable for obtaining large volumes of low-pressure air. The rotary type is somewhere in between, and the screw type in particular is the most popular type for general industrial use.
| Types | Picture | Principle | Features |
|---|---|---|---|
| Reciprocating type |  | Compress air by changing the volume of air through the reciprocating motion of the piston. | Low-speed rotation, high sound, and vibration. Cheap price. |
| Scrolling type |  | A combination of 2 spiral rotors that compress air according to the volume change of the space they separate. | Excellent silent performance. Not suitable for long continuous operation. |
| Screw type |  | The air is compressed by rotating a pair of screw rotors that change the volume produced in the threaded grooves. | Common oil-fed compressor construction. Less noise and vibration, highest efficiency in the medium class. |
| Turbine type |  | By rotating the impeller at high speed, it imparts speed and energy to the air, thereby increasing the pressure. | It is not as good at capacity adjustment as a volumetric compressor, so it is suitable for large-capacity base load machines. |
Secondly, from the point of view of “quality of discharged air”, turbine type can be roughly divided into oil-cooled type (oil-fed type) and oil-free type.
Oil-cooled compressors use oil for cooling during the compression process, and therefore, the discharged air may contain traces of oil. They are widely used in industrial applications where traces of oil can be mixed with the discharged air.
The reciprocating type (structure) is commonly used for small compressors, and the screw type is commonly used for medium-sized and above compressors. On the other hand, oil-free compressors are used for high cleanliness air output. They are widely used in industries and applications such as food and beverage, pharmaceutical, electronics, semiconductor, automotive, iron making, chemical, etc. Small compressors mainly use reciprocating and scroll type, medium compressors use screw type, and large compressors use turbine and screw type.
