Oil-free air compressors are a type of compressed air equipment widely used in various industrial and commercial fields. Compared with traditional oil air compressors, oil-free air compressors do not require the use of lubricating oil to cool and lubricate compressor components, so they can produce cleaner compressed air and avoid product pollution and environmental problems caused by oil pollution. The classification of oil-free air compressors can be carried out according to different working principles, application fields and technical characteristics.
First, classification according to the working principle:
1. Reciprocating oil-free air compressor: Reciprocating oil-free air compressor is one of the most common types of oil-free air compressor. It uses a reciprocating piston design that compresses air through the up and down movement of the piston. This type of oil-free air compressor is usually suitable for low pressure and small flow application scenarios, such as household tools and small factories.
2. Screw type oil-free air compressor: Screw type oil-free air compressor is a high-efficiency oil-free air compressor. It uses a screw rotor to compress air, has a high compression ratio and a large flow range. Oil-free screw compressors are suitable for medium and high pressure applications such as industrial production and manufacturing.
3. Centrifugal oil-free air compressor: centrifugal oil-free air compressor uses centrifugal force to compress air, and its working principle is similar to that of a centrifugal fan. This type of oil-free air compressor usually has a higher flow rate and a lower compression ratio, and is suitable for occasions where a large amount of compressed air is required, such as chemical plants and power plants.
1. Industrial oil-free air compressor: industrial oil-free air compressor is widely used in various industrial production and manufacturing fields, such as automobile manufacturing, electronic manufacturing, food processing and textile industry. They provide clean compressed air, ensuring product quality and production efficiency.
2. Medical oil-free air compressor: Medical oil-free air compressor is used in medical fields, such as hospital operating rooms and dental clinics. They are able to provide clean compressed air for medical equipment, ensure the normal operation of surgical procedures and medical equipment, and avoid patients.
3. Pharmaceutical oil-free air compressor: Pharmaceutical oil-free air compressor is used in the pharmaceutical industry to ensure a clean and sterile environment for drug production. They provide clean compressed air that meets pharmaceutical manufacturing standards, avoiding product contamination and cross-use.
Iii. Classification according to technical characteristics:
1. Ultrafiltration oil-free air compressor: ultrafiltration oil-free air compressor uses ultrafiltration technology to filter small particles and liquid pollutants in the air. They provide cleaner compressed air and are suitable for industries with high air quality requirements, such as electronics manufacturing and food processing.
2. Adsorption oil-free air compressor: Adsorption oil-free air compressor uses adsorption materials to remove pollutants and moisture in the air. They provide dry compressed air and are suitable for applications where dry air is required, such as spraying and instrumentation.
As a kind of hygienic and efficient compressed air equipment, oil-free air compressor is gradually replacing the traditional oil-free air compressor and is widely used in various fields. In the future, with the continuous progress and innovation of technology, oil-free air compressors will increasingly meet various special needs and play a more important role in health and energy saving.
