Oil and no oil in the air compressor generally refers to the amount of oil content in the gas discharged from the exhaust port of the air compressor. Generally, the oil content of the oil machine is relatively large, and the oil content of the oil-free oil machine is 0.01ppm. Therefore, the oil content is used to distinguish the oil and no oil in the air compressor.
There is also a full oil-free air compressor, it is not the use of oil lubrication, but the use of water lubrication, so the final discharge of the gas does not contain oil called full oil-free air compressor.
oil-free water lubrication air compressor advantages:
1. the current water removal equipment such as refrigerated dryers, non-heat regenerative dryers, and micro-heat regenerative dryers, the water removal function is lost due to the oil in the compressed air. However, the clean oil-free gas compressed by the all-oil-water lubricating air compressor fully protects the water removal equipment and reduces the additional funds brought by the maintenance of the water removal equipment.
2. use of oil air compressor not only need to change lubricating oil but also need to change oil filter regularly. Take a 7.5KW high-quality oil air compressor as an example, it consumes a minimum of 5kg of lubricating oil per month, which will cost 60kg more in one year. At the same time, in order to remove oil from compressed gas, it is necessary to use high-efficiency oil filter and replace the filter core many times, which is also a big expense.
3. because of the high viscosity of the lubricating oil, the current oil removal equipment cannot be completely removed, so that the oil-free air compressor compressed gas does not contain oil.
4. oil-free air compressor is used to provide compressed gas to the outside, the motor load will not be greatly reduced due to the pressure loss caused by oil removal equipment, thus achieving energy saving effect. At present, the high-quality three-stage oil remover will produce a pressure loss of 1 to 1.2kg during use. A 7.5KW air compressor will pay an extra 600W of power loss for every 1kg of pressure increase, and 6 degrees of electricity for every working day (10 hours, for example), this is another long-term intangible expense.
The water lubricated air compressor produced by granklin group does not contain oil. it only needs to replace the air filter element and water filter element regularly according to the manufacturer's requirements and maintain the head of the water lubricated air compressor.
With the development of the times, air compressor as a popular use has become more and more common. The function and use of the air compressor is that the air compressor can provide power by encrypting the air. After the compressed air can not be used as power, mechanical and pneumatic tools, and control
When the air compressor needs oil-free air, it is usually selected from the micro-oil air compressor, dry air compressor and water lubricated air compressor. The temperature of the micro-oil is low, the gap between the yin and yang rotors is small, and the loss of gas is small. The dry-type oil-free yin-yang rotor has a large gap and large gas consumption. Because there is no oil, the airtight effect is not good. One of the functions of the oil in the micro-oil air compressor is the oil film, which plays a sealing role. Efficiency is better.

Screw compressor is a kind of power equipment widely used in the field of petrochemical and industrial production, and its safe and reliable operation is of great significance to ensure production, so it is necessary to focus on it. A screw compressor is arranged in parallel in the cylinder of the main engine.
Small air compressor common piston air compressor, screw air compressor, screw air compressor miniaturization integration in today is also very common. The 5.5KW screw air compressor is a small product. The small water-lubricated air compressor produced by Shanghai Grank Group has stable gas supply and no oil. Many small businesses, as well as laboratories and other users are very fond of purchasing small air compressors.
View detailsA biopharmaceutical company needs aerobic culture gas in the process of producing yeast culture, and the quality of the gas source required for biological fermentation is very high. However, customers do not understand the selection of air compressors, but have very high requirements for the quality of compressed air, and in order to avoid
Water lubricated oil-free air compressor is generally a single screw air compressor, single screw water lubricated oil-free air compressor is used for compressor lubrication medium is water, using water as a seal, completely oil-free, pure oil-free compressed air, completely changed the production environment of some industries.
When choosing an air compressor, when transitioning from an oil-injected screw air compressor to an "oil-free screw air compressor", we will always have doubts about unknown products that we do not understand ". After all, air compressor family after years of development, has produced many kinds of compressor. The "water-lubricated screw air compressor" produced by Shanghai Granklin Group is one of the "oil-free screw air compressors.
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. The lubrication part is water, pure water. Air contains absolutely no oil, but it contains water. In the field of high gas quality requirements, such as textile, metallurgy, food, chemical industry, petroleum and air separation and other places that need pure oil-free compressed air, oil-free screw compressor can provide high-quality compressed gas to meet various needs, so the application prospect is broad.
What is the difference between the power frequency screw air compressor and the permanent magnet variable frequency screw air compressor? The general screw air compressor when the power frequency of the rotor is how much is how much, the frequency of the air compressor can be adjusted according to the required air volume The number of revolutions is greatly reduced, saving energy and electricity.
