Non oil water lubrication air compressor
The principle of operation is to inject lubricating water into the compression chamber and bearing through the pressure difference produced by the Bristol compressor. The design has the following characteristics:The lubricating water injection can have a certain stiffness of the water film is formed between the rotor and the star wheel, a wheel directly driven by the main rotor. Graphite bearing lubrication water lubrication wheel ends.The injected lubricating water can achieve the air tight function, which is better than the ordinary dry screw compressor.The lubricating water can absorb large amounts of heat compression, improves the compression efficiency, avoid between rotor and wheel, casing because of different thermal expansion coefficient and friction or may be stuck.The water can also reduce the noise due to high frequency compression.Bristow compressor company water lubrication air compressor use for the use of standard water purity, the use of parts and materials is the international standard brand 304, 316 stainless steel.Bristow compressor, nano silicon carbide and ceramic bearings are lubricated with water directly. They have good oxidation resistance, corrosion resistance and good lubricity.
Brief introduction of Bristol water lubricated oil-free screw compressorThe main characteristics of bestcopco non oil lubricated screw air compressor are reasonable structure, ideal force balance, no radial and axial force in operation, and only rotational force. The single-stage compression ratio is high, the structure size is small: high speed light load, easy to build fluid power lubrication.Bestcopco water lubricated single screw air compressor is a kind of oil-free air compressor series. Water is used as lubricant, which fundamentally solves the possible environmental pollution caused by lubricating oil. Relative to other oil free air compressor, it has the advantages of simple structure, compact structure, low speed, low noise, low exhaust temperature, high thermal efficiency, stable and reliable performance, low power, is the development trend of the new bestcopco oil free air compressor.
No oil lubrication of the machine, pay attention to the following, 1, lubricating part is water and pure water, pure water is preferable; 2, definitely not oily, but containing water; 3, water lubrication are single screw air compressor, dry oil-free machine cheaper than a tiny bit. 4, more than 55kW, the best use of water-cooled air compressor; water cooled, no oil or oil, need to set up a simple cooling tower, cooling effect of course should be strictly better than air-cooled.
