The water-lubricated single-screw air compressor is a series of oil-free air compressors. Water is used as a lubricant to fundamentally solve the pollution problem that the lubricating oil may cause to the environment. Compared with other oil-free air compressors, it has a simple and compact structure: low speed, low vibration and noise: low exhaust gas temperature: high thermal efficiency: stable and reliable performance, low specific power, etc. It is the development trend of new oil-free machines.
The working principle is that the pressure difference generated by the compressor itself is continuously injected into the compression chamber and the bearing during the compression process. The design has the following characteristics:
The injected lubricating water can form a water film with a certain rigidity between the rotor, the star wheel and the casing, and the star wheel is directly driven by the main rotor. Lubricating water directly lubricates the graphite bearings at both ends of the star wheel.
The injected lubricating water can achieve airtightness, which is superior to the general dry screw compressor.
Lubricating water can absorb a large amount of heat of compression, improve the compression efficiency, and avoid the possibility of friction or jamming between the rotor, the star wheel and the casing due to different thermal expansion coefficients.
Lubricating water also reduces the noise generated by high frequency compression.
