Advantages of oil-free and water-lubricated screw air compressors—Shared by Sollant

Oil-free water-lubricated screw air compressor is a compressor with ideal force balance and high efficiency. It has a reasonable structure and good symmetry, so that the oil-free air compressor has no unbalanced inertial force, and at the same time, the axial force and radial force of the star wheel on the screw also cancel each other out, so that it has an ideal force balance.

The oil-free water-lubricated screw air compressor adopts a high-efficiency design, which can provide 100% oil-free compressed air. The single unit has a large capacity, isothermal compression, and the displacement range is 2.3-21.3m³/min. Because water cooling outperforms lubricating oil, the compression process can be more effectively controlled, lowering the temperature and bringing the compressed air closer to the suction temperature.

The oil-free water-lubricated screw air compressor adopts the real oil-free lubrication technology, using water instead of lubricating oil for lubrication, cooling, sealing and noise reduction, providing high-quality oil-free air without pollution. At the same time, the cold dryer and the suction dryer can dry the compressed air, filter out the water, and the discharged water meets the environmental protection requirements without special treatment.

The oil-free and water-lubricated screw air compressor also has the characteristics of low noise and small vibration. Its superior dynamic balance system can effectively suppress vibration and has no special requirements for the foundation. The star wheel is customized with polymer materials, the working chamber is sprayed with lubricating water, and the intermediate transmission gear is made of resin material, which reduces the noise of the air compressor by about 3 to 7 decibels during operation.

The main engine of the oil-free and water-lubricated screw air compressor has a long service life, the symmetry of the structure and the reliability of the orifice setting make the rotor bearing load small, and can run for 50,000 hours, and the star wheel made of resin material can be used for 20,000-30,000 hours. , The service life of the air compressor is as high as 30 hours.

The power cost of the oil-free and water-lubricated screw air compressor is relatively low, which can be reduced to 44.3% through frequency conversion operation. In addition, due to the water lubricating oil method, the water itself has a certain cleaning effect, which can extend the maintenance cycle of the equipment and save maintenance costs. In addition, since no lubricating oil is required, the cost of lubricating oil is also saved.
