Oil-free screw air compressor is a typical type of positive displacement air compressor. The volume change in the main engine of the air compressor realizes the compression of gas. The change in volume relies on the rotation of the rotor in the screw air compressor. The following precautions should be taken when using an oil-free screw air compressor.
- Oil-free screw air compressors do not require oil for lubrication. The rotors of oil-free screw air compressors generally only require water for lubrication. Therefore, air compressor users do not need to add lubricating oil to oil-free screw air compressors.
- The user should set up a protective grounding wire for the oil-free screw air compressor to ensure that the metal shell of the air compressor is in good contact with the ground, and the grounding resistance should meet the standards.
- The oil-free screw air compressor should be placed in a ventilated and stable air compressor room and cleaned regularly.
- When the air compressor makes serious abnormal noise, air leakage and odor, the operation of the air compressor should be stopped immediately, and the cause can be found and the fault is eliminated before it can be operated again.
- When starting the oil-free screw air compressor again after an abnormal shutdown, pay attention to whether the pressure inside the air compressor has been cleared to avoid starting under pressure and causing the air compressor to trip.
- The filter element (foam sponge or felt) in the air compressor filter should be cleaned every three months to blow off the dust on the medium. Or clean the attached impurities with water.
- Routine maintenance of the air compressor includes simple dust cleaning, tightening loose bolts, checking parts for damage and aging, and regular maintenance of the air compressor main unit to ensure good performance of the air compressor.
The above are the precautions for the use of oil-free screw air compressors. Air compressor users must strictly implement them to ensure stable operation of the air compressor and extend the life of the air compressor.
