Description of air compressor (air compressor)
An air compressor is a device for compressing gases. The air compressor is similar to a water pump. Most air compressors are reciprocating piston type, rotating blade or rotating screw. Centrifugal compressors are very large applications.
There are many kinds of air compressor.
1. According to the working principle, it can be divided into three categories: volumetric type, dynamic type (speed type or turbine type), and thermal type compressor.
2. According to the lubrication method, it can be divided into oil free air compressor and oil lubricated air compressor.
3. According to the performance, it can be divided into: low noise, variable frequency, explosion proof and other air compressor.
4, can be divided into: according to the use of refrigerator compressor, air conditioning compressor, refrigeration compressor, oil field with compressor, gas stations, rock drill, pneumatic tools, vehicle braking, Windows and doors opening and closing, textile machinery, the tyre, plastic machinery with compressor, mine compressor, Marine air compressor, medical compressor, sandblasting spray paint.
5. It can be divided into fixed type, mobile type and closed type.
Volumetric compressor - a compressor that directly increases the pressure of a gas by changing its volume.
Piston compressor - is a volume compressor, its compression element is a piston, in the cylinder reciprocating movement.
Rotary compressor - is a volumetric compressor, compression by the forced movement of rotating components.
Slide compressor - is a rotary variable capacity compressor, its axial slide on the same cylinder block eccentric rotor for radial sliding. The air trapped between the slides is compressed back out.
Liquid-piston compressors are rotary volumetric compressors in which water or other liquids act as pistons to compress gases and then expel them.
Rotz double rotor compressor - a rotary volumetric compressor in which two rotz rotors engage with each other to trap the gas from the inlet to the outlet. No internal compression.
Screw compressor, rotary positive displacement compressor, in which the two rotor with a helical gear meshing, the two rotor meshing volume from large to small, so the gas compression side by side. The screw compression component of screw compressor is made by using the most new type of CNC grinding machine. Its reliability and performance can ensure that the operating cost of the compressor is extremely low during the service period. Adjusting compressor, integral compressor and desiccant series are all new products in L/LS series compressor.
Velocity compressor - a rotary continuous flow compressor in which a rotating blade at high speed accelerates the gas passing through it, thereby converting speed into pressure. This conversion occurs partly on the rotating blade and partly on a fixed diffuser or reflector baffle.
Centrifugal compressor - a speed compressor in which one or more rotating impellers (blades usually on the side) accelerate the gas. The main flow is radial.
Axial flow compressor - a speed compressor in which gas is accelerated by a rotor equipped with a blade. The main flow is axial.
Mixed flow compressor - also a speed compressor. The shape of its rotor combines some characteristics of both centrifugal and axial flow modes.
Jet compressors - use a high speed gas or steam jet to take the inhaled gas and then turn the speed of the mixture into pressure in a diffuser.
Permanent magnet variable frequency compressor -- because the variable frequency screw air compressor makes use of the stepless speed regulation feature of frequency converter, it can start gently through the controller or PID regulator inside the frequency converter. It can adjust the response quickly when the fluctuation of air consumption is large.
Single pole compression screw air compressor - the head is a screw air compressor consisting of a pair of Yin and Yang rotors. This machine is currently widely used screw air compressor.
Bipolar compression screw air compressor, the nose is composed of two rotor of Yin and Yang, gas after primary compression after entering secondary compression, compression ratio is high, the power and compressed air compressor reduce a notch.
Double pole permanent magnetic variable frequency air compressor -- a new energy-saving product developed after 2014, combined with permanent magnetic variable frequency and bipolar compression technology, it has high energy saving efficiency.
