Oil-free air compressors are a common type of air compression equipment that does not require the use of lubricating oil to keep the machine running smoothly. Oil-free air compressors have higher work efficiency and lower maintenance costs because they are oil-free, making them widely used in many fields. According to their different working principles and application fields, oil-free air compressors can be divided into the following categories.
1. Rotary oil-free air compressor: Rotary oil-free air compressor adopts rotary motion to compress air. The most common of them are screw type oil-free air compressors and turbine type oil-free air compressors. Oil-free screw air compressor realizes air compression through screw rotation, which is suitable for small and medium-sized industrial and commercial fields. The turbine type oil-free air compressor uses high-speed rotating turbine blades to compress air, which is suitable for large-scale industrial fields.
2. Reciprocating oil-free air compressor: reciprocating oil-free air compressor adopts reciprocating movement to achieve air compression. Reciprocating oil-free air compressors are suitable for smaller compressed air requirements, such as home and office use.
3. Film type oil-free air compressor: Film type oil-free air compressor realizes air compression through a series of diaphragm vibration. Film type oil-free air compressor has the characteristics of simple structure, low noise, easy maintenance, etc., which is suitable for some places with high noise requirements.
4. Centrifugal oil-free air compressor: centrifugal oil-free air compressor uses centrifugal force to compress the air, which is suitable for some occasions requiring high pressure, such as the petroleum and chemical industry.
5. Variable frequency oil-free air compressor: Variable frequency oil-free air compressor adopts frequency conversion technology, which can adjust the speed and output power according to actual needs to achieve higher energy efficiency and energy-saving effects.
6. Other types of oil-free air compressors: In addition to the above common types, there are some other types of oil-free air compressors, such as ion fans, acoustic compressors, etc., which have their own characteristics and advantages according to different working principles and application fields.
In summary, the classification of oil-free air compressors can be divided from many angles such as motion form, working principle and application field. Each type of oil-free air compressor has its own applicable occasions and advantages, and users should make reasonable choices according to specific needs when choosing.
