How about water lubricated oil-free screw air compressor

2026-04-13Views:

Water-lubricated oil-free screw air compressor is an efficient and environmentally friendly compressed air equipment. The following is a detailed description of the water lubricated oil-free screw air compressor, the product features of Shanghai Grankering Group:

1. working principle and structure

the water-lubricated oil-free screw air compressor is mainly composed of a cylindrical screw and two symmetrically arranged planar star wheels to form a meshing pair. In the working process, it uses water as the lubricating and cooling medium, and continuously injects lubricating water into the compression chamber and the bearing through the pressure difference generated by the compressor itself. This design allows the machine to operate without radial and axial forces, only with rotational forces, thus ensuring an ideal force balance.

2. performance characteristics

  1. oil-free compression: Water is used as the lubrication and cooling medium to completely avoid the contact between oil and compressed air, thereby ensuring the purity of compressed air. This feature makes it widely used in medicine, food industry, photovoltaic products, new energy, high-precision instruments and other industries.
  2. High efficiency: Because the specific heat of water is large and a large amount of compression heat can be absorbed during the working process, the water lubricated oil-free screw air compressor has high working efficiency. Compared with the traditional dry screw air compressor, its energy consumption is lower and more energy saving.
  3. Low noise and low vibration: The meshing auxiliary star wheel of the water-lubricated oil-free screw air compressor is made of polymer material, and the box plate is pasted with sound-absorbing material, so the operating noise is extremely small. At the same time, its superior power balance system can effectively control the vibration source and make the machine run smoothly.
  4. Environmental protection: Because oil is not used, the risk of oil pollution is reduced and it is more environmentally friendly. In addition, it is also equipped with a water gas separator to effectively remove the moisture in the compressed air and ensure the dryness of the compressed air.
  5. Low maintenance costs: Compared with traditional air compressors, water-lubricated oil-free screw air compressors save consumables such as lubricating oil and oil filters and oil-gas separation cores, thereby reducing maintenance costs.

3. applicable industry

due to its oil-free, high efficiency, environmental protection and other characteristics, water-lubricated oil-free screw air compressors are widely used in medicine, food industry, photovoltaic products and new energy, high-precision instruments and other factories that require high-quality compressed air.

In general, the water-lubricated oil-free screw air compressor of Shanghai Granklin Group has shown significant advantages and application prospects in many industries by virtue of its unique working principle and performance characteristics.
