The decrease of compressed air quality of screw air compressor is mainly manifested by the increase of oil content and impurities such as dust in compressed air. The former is one of the most common phenomena.
The result that the air quality of screw air compressor decreases easily is as follows:
As we all know, the product of compressor is compressed air. Whether it is used as power or as gas source, the quality of compressed air is one of the most concerned problems for users. Therefore, once the compressed air quality falls, it will not only cause the compressed air quality not up to the standard and can not be used, damage the compressed equipment, but also cause explosion because of the high oil content in the air. Therefore, for a long time, how to effectively improve the compressed air quality of the air compressor is an important research object.
How to improve the quality of compressed air in screw air compressor?
Because of the above hazards, people constantly hope that the higher the compressed air quality of the air compressor, the better. At present, in order to improve the quality of compressed air, the most commonly used methods are as follows:
1. Loading air filter equipment to achieve the purpose of improving and tightening air quality. For example, screw air compressor device air filter, oil and gas separator, etc.
2. Control the quantity of smooth oil. As the oil content in the compressed air increases easily when the smooth oil is excessive, the demand to control its content within a reasonable range can not be too low or too high.
3. Check the throttle hole of one-way valve, oil-gas separator, minimum pressure valve spring and other components to see if they can be obstructed or damaged. Once it is found that these components are not working properly, they must be stopped for disposal.
4. Check the exhaust pressure. The exhaust pressure of screw air compressor is too low, which will also lead to the reduction of compressed air quality. Therefore, we need to ensure that the set value of unloading pressure of air compressor is within an appropriate range.
