Oil-free air compressor is an efficient and hygienic air compressor equipment, its working principle is to compress the air through the compressor and discharge it without lubricating oil. According to different classification standards, oil-free air compressors can be divided into the following categories:
1. Classification by compressor type:
- Screw oil-free air compressor: Screw oil-free air compressor is a more widely used type in the market. Its working principle is through the movement of two screws mesh with each other, the air is compressed and discharged. The screw type oil-free air compressor has the characteristics of simple structure, stable operation and low noise, which is suitable for large-scale industrial production fields.
- Piston oil-free air compressor: The piston oil-free air compressor compresses the air through the movement of the piston. Piston type oil-free air compressor has the characteristics of simple structure, dimension, etc., suitable for small industrial production field or home use.
2. Classification by use:
Industrial oil-free air compressor: Industrial oil-free air compressor is mainly used in industrial production fields, such as automobile manufacturing, chemical industry, food processing, etc. The oil-free air compressor for industrial use has the characteristics of high efficiency and energy saving, and can provide a stable air supply.
Household oil-free air compressor: household oil-free air compressor is mainly used in household use, such as inflatable tires, inflatable swimming pools, etc. Household oil-free air compressor is small in size, easy to operate and easy to carry.
3. Classified by work pressure:
Low pressure oil-free air compressor: Low pressure oil-free air compressor is suitable for occasions where the air pressure is not high, such as household inflation tools.
- Medium pressure oil-free air compressor: Medium pressure oil-free air compressor is suitable for occasions with high air pressure requirements, such as automobile manufacturing, mechanical processing, etc.
High-pressure oil-free air compressor: high-pressure oil-free air compressor is suitable for occasions with very high air pressure requirements, such as aerospace fields.
4. Classification by control mode:
- Constant frequency oil-free air compressor: The compressor running speed of constant frequency oil-free air compressor is fixed and cannot be adjusted according to actual needs.
- Variable frequency oil-free air compressor: The compressor running speed of variable frequency oil-free air compressor can be adjusted according to actual needs, which has energy-saving effect.
5. Classified by configuration mode:
- Single oil-free air compressor: single oil-free air compressor refers to an oil-free air compressor that works independently and is suitable for small industrial fields.
- Multi-unit oil-free air compressor: Multi-unit oil-free air compressor refers to the joint work of multiple oil-free air compressors, which is suitable for large-scale industrial fields.
In short, oil-free air compressor is a widely used air compressor equipment, which can be classified according to multiple classification criteria such as compressor type, use, working pressure, control mode and configuration mode. Each classification has its own characteristics and application areas, users can choose the right oil-free air compressor according to the actual needs.
