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.
The following is the technical schematic diagram:
There must be internal wear and aging during the long-term operation of the screw air compressor. Therefore, it is very important to regularly maintain and replace consumables in time. Most users are not very clear about consumables. The following is a detailed introduction of the consumables of the screw air compressor. What are the screw air compressor consumables we often say?
View detailsFrom the oil content point of view, the oil and no oil in the air compressor generally refers to the amount of oil in the exhaust port of the air compressor. There is also a completely oil-free air compressor, which is not lubricated by oil, but by water, so the final discharged gas does not contain oil.
The air compressor is to provide air source power. It is the core equipment of the pneumatic system. The main body of the electromechanical air source device. It is a device that converts the mechanical energy of the driving force (usually an electric motor or a diesel engine) into gas pressure energy. It is a compressed air. Pressure generator.
Precautions for dry oil-free air compressor: 1. Safety matters must be observed during use to prevent fire, electric shock, personal injury and other accidents. 2, keep the workplace clean; chaos can easily lead to accidents. 3, pay attention to the workplace environment: air compressor can not let the wind and rain, do not work in damp and dark places, do not work in the storage of flammable and explosive liquid gas and dusty places.
For medicine, food, semiconductor, chemical industry, fermentation and other industries, oil-free and clean compressed air must be the first choice. Oil-free oil-free screw air compressor, water-lubricated oil-free screw air compressor, oil-free scroll air compressor and oil-free centrifugal air compressor are common oil-free.
Air compressors that can be used in medical systems need to be oil-free, and the air cannot contain any grease. In the production process of medicines and medical devices, air products containing oil and gas are unqualified.

The benefits of "fixed screw air compressor" are stable, high efficiency, and can achieve higher displacement and pressure. Routine maintenance is also less. "Fixed screw air compressor" in the leader "water-lubricated air compressor" series, "Shanghai Granklin Group" production of "oil-free air compressor" products. Durable, oil-free air, simple maintenance, is a high-quality "fixed screw air compressor". To do a good job in products is the voice of all the factory people of granklin group. Let users rest assured, no worries, better use of "oil-free compressed gas".
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, and manufacturers often choose suitable models according to actual needs. Several common oil-free air compressors are: oil-free piston air compressor, no
The air filter element is replaced every 1000-1500 hours under normal conditions. For places where the environment is particularly harsh, such as mines, ceramic factories, cotton mills, etc., it is recommended to replace the air filter element every 500 hours. When cleaning or replacing the air filter element, the components must be matched one by one to prevent differences.
