    What is the working principle of air filter?

      General filter core is medium, by fiber filter, sponge, such as material composition, compressed air of solid and liquid particles (drop) after filtering material of interception, condensed in the filter surface (inside and outside).Accumulate in the droplets on the surface of the filter and magazine via gravity settling to the bottom of the filter and then the automatic drainer or artificial.

  • Air compressor labeling method

    Air compressor labeling method
    In the 21st century air compressor market competition is intense, consumers in the choose and buy products, often will be included in the purchase of standard machine quality and price.Therefore, will be on the market of various labeling method, also a common movement as a force to protect consumers.
  • The characteristics and the types of air compressor

    The characteristics and the types of air compressor
    Compressor main types of columns, the following is the definition of all kinds of compressor.CAM type, diaphragm and the diffusion pump compressor is not included, because they use special and relatively small size.
    Positive displacement compressor, is to a certain amount of continuous airflow limitation in a closed space, make the pressure.
    Reciprocating compressor - is a positive displacement compressor, the compression components is a piston, within the cylinder for reciprocating motion.
    Rotary compressor - is a positive displacement compressor, compression is implemented by forcing movement of rotating components.
    Sliding vane compressor, rotary varactor is compressor, its axial sliding vane with radial sliding cylinder block on the eccentricity of the rotor.Intercept the vane and the air is compressed between the back out.
    Liquid - piston compressor, rotary positive displacement compressor, in which water or other liquid as the piston to compress gas, then the gas discharge.
    Roots double rotor compressor, rotary positive displacement compressor, in which the two roots rotor meshing with each other in order to stop the gas, and from inlet to outlet.No internal compression.
    Screw compressor, rotary positive displacement compressor, in which the two rotor with a helical gear meshing, and the gas compression side by side.
    Speed type compressor is rotary continuous air compressor, in which the high-speed rotating blade through its gas acceleration, thereby will speed can be converted into pressure.This transformation occurs on the rotor blades, part the diffuser in fixed or back panel.
    Centrifugal compressor, speed type compressor, in one or more rotating impeller (blade usually on the side) accelerates a gas.The main air flow is radial.
    Axial flow compressor, speed type compressor, in which the gas by bladed rotor speed.The Lord is axial airflow.
    Mixed flow compressor, speed type compressor, its the shape of the rotor is a combination of some characteristics of both centrifugal and axial flow.
    Gas or steam injection compressor - using high-speed take suction gas jet stream, and then in the diffuser will be the speed of the mixed gas is converted to pressure.
