Characteristics of Water Lubricated Screw Air Compressor

The main features of the water lubricated screw air compressor are: reasonable structure, ideal force balance; no radial and axial force during operation, only rotational force. Single-stage compression ratio is high, the shape of the structure size is small: high speed light load, easy to establish hydrodynamic lubrication.

Water-lubricated single-screw air compressor is an oil-free air compressor series, which uses water as a lubricant to fundamentally solve the lubrication problem.

the possible pollution of oil to the environment. Compared with other oil-free air compressors, it has the advantages of simple and compact structure: low speed, low vibration and noise: low exhaust temperature: high thermal efficiency: stable and reliable performance, and low specific power. It is the development trend of new oil-free oil machines.

Its working principle is to continuously inject lubricating water into the compression chamber and the bearing during the compression process through the pressure difference generated by the compressor itself. This design has the following features:

1. The injected lubricating water can form a water film with certain rigidity between the rotor, star wheel and casing;

2. The star wheel is directly driven by the main rotor, and the lubricating water directly cools the self-lubricating bearings at both ends of the star wheel;

3, the injection of lubricating water can achieve airtight effect, this role is better than the general dry screw compressor;

4. The lubricating water can absorb a large amount of compression heat, improve the compression efficiency, and avoid the possibility of friction or jamming due to different thermal expansion coefficients between the rotor, star wheel and casing;

5, lubricating water can also reduce the noise generated by high frequency compression.
