• Selection Guide for Screw Air Compressor
    • 2021-04-01

    1. Selection of working pressure (exhaust pressure): When the user is preparing to purchase an air compressor, first determine the working pressure required by the air end, plus 1-2 The margin of bar, and then select the pressure of the air compressor, (the margin is to consider the pressure loss from the installation location of the air compressor to the actual gas end pipeline distance, and the ...

  • How does a screw compressor work?
    • 2021-04-08

    The screw compressor cylinder is equipped with a pair of intermeshing spiral female and male rotors. Both rotors have several concave teeth, and the two rotate in opposite directions. The main rotor (also called a male rotor or a convex rotor) is driven by an engine or an electric motor (mostly driven by an electric motor), and the other rotor (also called a female rotor or a female rotor) is driv...

  • PSA Oxygen Generator System and Oxygen Flushing Cylinder System Suitable for Hospitals

    PSA Oxygen Generator System and Oxygen Flushing Cylinder System Suitable for Hospitals

    Air contains 21% oxygen, 78% nitrogen, 0.9% argon and 0.1% other trace gases. PSA oxygen generator uses zeolite molecular sieve as adsorbent. Use two containers with zeolite molecular sieves (two towers, four towers or six towers) as adsorbents, using the principle of pressure adsorption and decompression desorption to adsorb and release oxygen from the air, thereby separating the oxygen from the ...

  • The principle, characteristics and application fields of PSA oxygen generator
    • 2021-06-18

    The working principle of PSA oxygen generator: The normal air composition is: nitrogen (N2) accounts for about 78.1%, oxygen (O2) accounts for about 20.9%, and rare gases account for about 0.939% (helium He, neon Ne, argon Ar, krypton Kr, xenon Xe, radon Rn), Carbon dioxide (CO2) accounts for about 0.031%, and other gases and impurities account for about 0.03% PSA (Pressure Swing Absorption) oxyge...

  • What is the difference between a permanent magnet screw air compressor and a soft starter?
    • 2021-06-18

    Soft Starter Air Compressor:A soft starter is actually a motor control device with motor soft start, soft stop, light load energy saving and multiple protection functions. It is mainly a three-phase parallel thyristor and its electronic control circuit connected in series between the power supply and the controlled motor. By controlling the conduction angle of the three-phase parallel thyristor, t...

  • Analysis of oil failure of oil injected screw air compressor
    • 2021-07-02

    Generally, the oil content of the compressed air of the oil injected screw air compressor is not more than 3ppm. When the oil content of the compressed air exceeds this standard, we usually call it high fuel consumption, commonly known as running oil or flying oil. Air compressor oil running is a headache problem that has plagued manufacturers, distributors and users for a long time, and it is als...

  • Why is the frequency conversion screw air compressor frequently loaded and unloaded? How to deal with it?
    • 2021-07-02

    Compared with conventional screw air compressors, variable frequency screw air compressors use adjustable air volume and smooth start-up. The air supply pressure is more stable than conventional screw air compressors , but sometimes variable frequency screw air compressors like power frequency compressors appear: Frequent loading and unloading situations. According to the analysis of this phenomen...

  • What is a VSD screw air compressor? What are the benefits of using it?
    • 2021-07-21

    (Variable Speed Drive) VSD Air Compressor Variable Speed Driver , usually abbreviated as VSD, is a symbol of the compressed air field. The air compressor equipped with VSD can automatically adjust its operating speed to accurately match the compressed air demand in real time. Considering that the biggest aspect of the total cost of ownership of an air compressor is the power it consumes, not the p...

  • How to deal with the high temperature shutdown of the air compressor?
    • 2021-07-21

    There are many reasons for the abnormal shutdown of the air compressor. Excessive temperature is an important reason. Excessive temperature will cause some parts of the air compressor to fail to operate normally, resulting in shutdown. Reason analysis of high temperature of screw air compressor: ① Insufficient amount of lubricating oil, incorrect specifications of lubricating oil, different viscos...

  • Reasons and solutions of screw air compressor not pumping up and insufficient pressure
    • 2021-07-21

    The main manifestations of air compressor not pumping up and insufficient air pressure are as follows: the air compressor does not discharge air under pressure and when the main engine is running and the air compressor is inflating the air tank, the barometer indicates the starting pressure value of the air pressure. A: General reasons and solutions for the air compressor not pumping up when loade...

  • What maintenance should be done during the decommissioning of pressure vessels?
    • 2021-08-06

    The maintenance content of the pressure vessel in the air compressor system during the outage period is as follows: 1.Keep the pressure vessel dry and clean to prevent atmospheric corrosion. Scientific practice has proved that dry air generally does not corrode carbon steel and other ferroalloys. Corrosion starts only when there are dust, dirt or old corrosion products on the metal surface when we...

  • Analysis on the Causes of the Tripping Failure of the Safety Valve of the Screw Air Compressor
    • 2021-08-06

    Recently, I have encountered the same problem as a customer inquiries: the safety valve of the air compressor frequently jumps and the oil is sprayed. I don't know where the problem is? Through many years of service experience, it is concluded that the main factors of the safety valve take-off failure of the screw air compressor are the following four aspects: 1. The large oil partial pressure dif...
