oil-free air compressor is divided according to whether the compressed air contains oil, which corresponds to oil air compressor or micro-oil air compressor. Oil-free air compressors are distinguished according to different compression forms or different host structures. Several common oil-free air compressors are: oil-free piston air compressors, oil-free dry screw air compressors, oil-free water lubrication air compressors (oil-free water lubrication single screw air compressors), centrifugal air compressors.
Compared with other forms of oil-free air compressor, oil-free water lubrication air compressor has obvious advantages:
1, the use of water as a compression seal, cooling medium, the use of low cost.
Through advanced sealing and isolation technology, the compressed air is cleaner and can be pure oil-free.
3, the volumetric efficiency is higher, more energy-saving, more than two dry twin screw energy saving more than 15%, more than a dry twin screw energy saving more than 36%.
4, to avoid frequent dry screw, high host maintenance, more stable and reliable.
5, lower noise, single screw axial and radial force balance, star wheel in the water film lubrication with the screw free rotation, so the host components in low load smooth operation, to ensure low noise and durability.
6, compared with the traditional air compressor to save lubricating oil and oil filter and oil and gas separation core and other consumables, thereby reducing maintenance costs (one year is the traditional micro-oil air compressor 1/5 maintenance costs)
7, no oil, so the use of more environmentally friendly.
Applicable industry
(1) Medicine.
(2) The food industry.
3, photovoltaic products and new energy.
4. High precision instrument.
5 The hospital.
Other factories that require high-quality compressed air.
Features of 1. oil-free screw air compressor:
1, the world's most advanced screw compressor technology, the use of water as a compression seal, cooling medium, the use of low cost, than the dry twin screw, to ensure 100% compression.
2. Through advanced sealing and isolation technology, the compressed air is cleaner, and the parts of the air compressor are completely free of lubricating oil and can be pure.
3, the volumetric efficiency is higher, more energy-saving, more than two dry twin screw energy saving more than 15%, more than a dry twin screw energy saving more than 36%.
4. The compressor has few parts and no wearing parts, so it runs reliably and has a long life. Avoid dry screw frequent, high host maintenance, more stable and reliable.
5, lower noise, single screw axial and radial force balance, star wheel in the water film lubrication with the screw free rotation, so the host components in low load running smoothly, to ensure low noise and durability, with the characteristics of forced gas, volume flow is almost not affected by the exhaust pressure, in a wide range of speed can maintain high efficiency..
6, compared with the traditional air compressor to save lubricating oil and oil filter and oil and gas separation core and other consumables, thereby reducing maintenance costs (one year is the traditional micro-oil air compressor 1/5 maintenance costs)
7, a high degree of automation, comes with the latest generation of microcomputer controller has a perfect self-management function, the operator does not have to go through a long period of professional training, can achieve unattended operation.
8. Compared with the traditional oil machine and dry air compressor, the air compressor has lower maintenance cost, and only needs to replace the water, water filter element and air filter element.
9. There is no unbalanced inertial force, it can run smoothly at high speed, and can realize no basic operation. It is especially suitable for mobile compressors with small size, light weight and less floor space.
2. why air compressors are generally single screw, rather than twin screw?
The reason is that when the single screw is running, the screw and the star wheel have a speed difference, one-way compression, air is easy to compress, and the speed is low.
The twin-screw is co-extrusion, which requires high speed, and the lubrication of water is not enough compared to the oil density, and the compressed air is easy to flow backwards.
Need to pay attention to two points
1. The lubrication part is water, preferably pure water.
Air contains absolutely no oil, but it contains water.
