  • How to choose dryer based on Screw air compressor

    Compressed air is the most important power source in the production industry today, and the compressed air system of Screw Air Compressor is very important for the production enterprise.The correct use of screw air compressor purification equipment dryer and filter in the system, can improve the service life of the pneumatic control system, reduce control system failure and fault, has important significance to improve the work efficiency and economic benefit.

    So how to choose dryer based on Screw Air compressor ?According to the following two side :

    1.Type of screw air compressor

    If using oil lubricated screw air compressor, its oil content indicator >15mg/m3 should be equipped with high efficiency and precision filter and select the external heating type micro-heat regeneration dryer.

    2.Exhaust temperature and exhaust pressure of screw air compressor

    According to the exhaust temperature and exhaust pressure of screw air compressor, the drying device and supporting equipment can be selected.

    When the exhaust temperature above 35 ℃, consideration should be given before the drying machine and oil removal filter equipment after cooler, the gas temperature drop to below 35 ℃.When low exhaust pressure is lower than 0.5mpa, no heat regeneration and micro-heat regeneration dryer should be used, and the external heating, residual heat and internal heat regeneration and drying device should be used with large filling volume and deep adsorption.When the exhaust pressure below 0.2 MPa, again after freeze drying machine should be treated with hot regeneration secondary drying device to get to 40 ℃ under good drying effect.

  • Three steps of type selection of screw air compressor

    Selection of Screw Air Compressor: first step: determining working pressure
    When the air compressor is selected, we must first determine the working pressure needed by the air end, add the allowance of 1-2 bar, and then choose the pressure of the air compressor. Of course, the size of the pipe path and the number of turning points are also the factors that affect the pressure loss. The greater the pipe path and the less turning point, the smaller the pressure loss, and vice versa, the pressure. The greater the loss.
    Therefore, when the distance between the air compressor and each gas end pipeline is too far away, the path of the main path should be properly enlarged. If the environmental conditions conform to the installation requirements of the air compressor and the conditions permit, it can be installed near the gas end.
    Second steps of air compressor selection: determining corresponding volume flow rate
    1, when selecting the air compressor, we should first understand the volume flow of all the gas consuming equipment, and multiply the total volume of the flow by 1.2.
    2, to understand the volume flow parameters of gas consumption equipment and select the type of air compressor.
    3. The transformation of air compressor station can refer to the original parameter value and the actual gas consumption.
    Third steps of air compressor selection: determine power supply capacity
    When the power is constant, when the speed changes, the volume flow and the working pressure also change correspondingly. The speed is reduced, and the exhaust is correspondingly reduced, and so on.
    The selection power of screw air compressor is to meet the working pressure and volume flow capacity, and the power supply capacity can meet the power used by the matching driving motor.
  • Advantages of Oil-free Screw Air Compressor.

    Because of oil-free Screw Air Compressor screw on the compression process, the whole host of lubrication, sealing and cooling by water, as a result, the letter but oil-free air compressor is oil-free compressed in the true sense.

    1) unlubricated structure: the whole machine has no oil to participate in, and the lubricant we use is water, so it can provide users with very clean compressed air.Operation and maintenance costs are extremely low (no air compressor oil, oil fine separation core, oil filter).

    2) ideal isothermal compression: because the water cooling performance is far higher than that of air compressor oil, we only 40 ℃, the machine running temperature close to the suction temperature, achieve ideal isothermal compression efficiency.

    3) real environmental protection products: because there is no lubricating oil, there is no oil pollution, and all the parts are made of anti-rust materials, such as stainless steel, copper alloy, ceramic and carbon fiber, etc.High precision water filter ensures that the water is kept clean.

    4) high efficiency: the pure water used by the BEST-F(N) series air compressor has three functions: sealing, cooling, and lubrication, which is 20% higher than the normal dry compressor.

The company mainly produces and operates engineering, mining, agricultural machinery, piston and screw air compressors, down-the-hole drilling rigs, etc.
