The advantages of oil-free and water-lubricated screw air compressor mainly include:
Low cost of use: This type of air compressor uses water as the medium for compression and sealing, replacing the traditional lubricating oil, thus reducing the cost of use.
Pure compressed air: Through advanced sealing and isolation technology, the oil-water lubricated screw air compressor can provide pure compressed air to ensure that there is no oil in the compression process, which meets the application requirements for high air quality.
High efficiency and energy saving: The oil-water lubricated screw air compressor has higher volumetric efficiency, and its energy-saving effect is significantly improved compared with the traditional dry twin-screw air compressor. Specifically, it is more than 15% more energy-saving than the two-stage dry twin-screw and more than 36% more energy-saving than the first-stage dry twin-screw.
Stable and reliable: Due to the frequent occurrence of dry screws and the high maintenance of the main engine, the oil-water lubricated screw air compressor is more stable and reliable during operation.
Low-noise operation: The axial and radial forces of the single screw are balanced, and the starwheel rotates freely with the screw under water film lubrication to ensure the smooth operation of the main engine components under low load, thereby reducing the operating noise and improving the durability of the equipment.
Zero emission of environmental protection: only the lubricating water similar to the drinking water standard in the machine participates in the cooling, sealing and lubrication in the compression process, and there is no “three wastes” emission in the whole operation process, which meets the requirements of environmental protection.
Long service life: Due to the fact that the interior is made of high-quality materials and has an anti-rust treatment, the service life of the oil-water lubricated screw air compressor is relatively long.
To sum up, the oil-water lubricated screw air compressor has been widely used and recognized in many industrial fields for its high efficiency, environmental protection, stability and low noise.
