• 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...

  • 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...

  • Common failures of air compressors and analysis of frequency conversion reformation
    • 2021-08-27

    Due to the lack of understanding of air compressors by some business managers, the continuous operation of the air compressor is based on the principle of keeping the equipment in good condition and not repaired, resulting in long equipment running time but lack of maintenance, and failures may occur at any time. 1. The subjective cause of the accident The management of the equipment supervisor is...

  • How to extend the service life of your screw air compressor?
    • 2021-08-27

    Many factories believe that the maintenance of screw air compressors is maintenance of 3 filters and 1 engine oil in 2000hrs. But this is only basic maintenance. In-depth maintenance is divided into 5 stages. If you can do a good job of deep maintenance. Then your air compressor can have a longer service life. Maintenance time and content of the air compressor.   1. Maintenance time and ...
