Insiders watch the doorway while laymen watch the excitement. Precautions for the use of oil-free air compressor include installation environment, operating conditions, raw material quality, maintenance, etc. In addition to these, you must understand the following exhaust pressure, compressed air quality, equipment exhaust volume, etc.

1、 Discharge pressure of oil-free air compressor

In the precautions for oil-free air compressor, the higher the exhaust pressure, the more energy consumption. The sum of the service pressure, pipeline resistance loss and the pressure drop of the supporting equipment is set as the lower limit of the rated exhaust pressure of the selected screw air compressor. In general, the diameter of the gas transmission pipeline should be larger to reduce the resistance loss and achieve the purpose of reducing energy consumption during long-term operation. The higher the discharge pressure of the compressor, the more energy consumption. Therefore, do not select compressors with high exhaust pressure

（1） Compressed air quality

According to the requirements of industrial gas equipment for compressor gas, screw air compressor and supporting equipment should be appropriately selected. The following points need to be considered:

1) To reduce the oil content in the compressed air, the oil removal purifier can be used. If you want to achieve a higher treatment effect, you can use multi-level treatment, which can effectively reduce the oil content in the air.

2) To reduce the moisture in the compressed gas, supporting water removal equipment, such as condenser, oil filter or cyclone, can be used. These devices help to remove moisture from the gas and reduce the probability of equipment or system failure.

（3） Air displacement of oil-free air compressor

Calculate the actual total gas consumption × 1.1-1.2 coefficient, and use it as the model with exhaust capacity. If the selection is too low, it cannot reach the specified value of the gas consumption equipment. If the selection is too large, it will cause large energy consumption and uneconomical load reduction operation. At the same time, the purchase cost of large exhaust screw air compressor is high.

Besides the installation environment and sub-branch conditions, other core factors that affect the use of oil-free air compressor are listed above. Be careful to collect them. The long-term use of any equipment cannot be separated from careful maintenance and attention, so it is really important to start from details. The handling of details often determines the operation effect of the whole system, so we must pay special attention to it so as not to ignore the details.
