Air compressor is a machine that converts mechanical energy into standard air pressure energy. According to the working principle, it can be divided into three types: volume type, turbine type and thermal type. Centrifugal air compressors, scroll air compressors and screw air compressors are common machines and equipment produced in factories.
1. Scroll air compressor: The scroll air compressor causes a large number of compression chambers according to the static scroll disk line and the gear teeth of the scroll disk, and compresses the gas according to two staggered spiral twisted dragon blades to complete the suction and compression of the gas. Because of its unique structure, scroll air compressor has simple structure, small size, low noise, robustness and durability, and strict sealing requirements.
2. Screw air compressor: At this stage, twin screw air compressors are the most used in the market. The operation of the double screw air compressor is mainly through the rotation of the rotor, and the volume of the tooth root is expanded. The steam body is pressed into the exhaust pipe end according to the gear teeth of the Yin and Yang rotor, and discharged according to the exhaust pipe. Because of its good stability, simple structure and, of course, good effect, there are also problems such as large noise, large weight and short cycle.
3. Centrifugal air compressor: centrifugal air compressor belongs to turbine compressor. Direct motor drive is usually used. Under the ultra-high speed rotation of the rotor, the impeller drives the steam body to run at high speed, and the interaction with the vortex shell causes the high-pressure and high-flow steam body to convert the mechanical energy into the kinetic energy of the steam body. Because of its simple structure, simple structure, small size, good sealing type, light weight and small vibration, it is called one of the promising air compression methods in the future under the advantages of good rated working conditions.
