The advantages of water lubricated oil-free screw air compressor

Water lubricated oil-free screw air compressor ensures that compressed air is oil-free, pure and dry, efficient and energy-saving, environmentally friendly and low maintenance through water lubrication, sealing and cooling. It is suitable for industries such as food and medicine that require high-quality air.

1. Ideal force balance: The oil-free air compressor is equipped with a star wheel symmetrical structure on both sides of the screw, which not only eliminates unbalanced inertial forces, but also cancels out the axial and radial forces used on the screw, making it have ideal force balance.

2. Oil free compression: By using soft water and purified water as lubrication and cooling media, the contact between oil and compressed air is avoided, ensuring the purity of the compressed air. Replacing oil with water achieves the four major functions of lubrication, cooling, sealing, and noise reduction, providing high-quality 100% oil-free air that is pollution-free. The discharged water does not require special treatment and meets environmental requirements, reducing the risk of oil pollution and making it more environmentally friendly.

3. Water gas separation: Equipped with a water gas separator, it effectively removes moisture from the compressed air, ensuring the dryness of the compressed air.

4. Multi stage cooling: Due to the lack of oil cooling effect, pre coolers, intercoolers, and post coolers are usually configured to perform multi-stage cooling of compressed air to achieve the specified exhaust temperature.

5. Excellent shaft seal: Use high-performance shaft seals on the rotor shaft to prevent lubricating oil from leaking into the compressed air and ensure oil-free compression effect.

6. High precision machining: The rotor adopts precision gear matching, excellent machining technology, and high-precision machining equipment to ensure that the male and female rotors mesh without direct contact.

7. Low noise and low vibration: The superior power balance system of the oil-free air compressor can effectively control the vibration source, and the operation is extremely balanced. There are no special requirements for the foundation. The star wheel is made of specially customized polymer material, and the working chamber is sprayed with lubricating water. There is no transmission gear in the middle, so the operating noise is extremely low.

8. High performance materials: The rotor is usually made of all stainless steel to ensure excellent mechanical properties and corrosion resistance.

9. High efficiency: In theory, oil-free air compressors have no clearance capacity and a large single machine capacity. Ideal isothermal compression, due to the good thermal conductivity of water, when lubricating water is injected into the compression chamber, the temperature will drop to 45 ℃, close to the suction temperature.

10. Low maintenance cost: Water lubrication reduces dependence on oil, eliminating expensive lubricants and filters, thereby reducing maintenance costs and workload.

11. Long service life of the host: The symmetry of the structure and the setting of the return hole enable the radial and axial forces generated during the operation of the compressor to be balanced. Therefore, the rotor bearing has extremely low load and can operate for 50000 hours; The star wheel made of resin material can be used for 25-30000 hours, and the design life of the compressor can reach up to 300000 hours.

12. Suitable for special industries: Due to the oil-free nature of compressed air, water lubricated oil-free screw air compressors are suitable for industries that require extremely high air quality, such as food, medicine, electronics, chemicals, beverages, semiconductors, etc.

The characteristics of water lubricated oil-free screw air compressors make them advantageous in specific applications, especially in situations where oil-free, dry, and clean compressed air is required.
