What is the oil-free screw air compressor used?

In recent decades, the research on oil-free screw air compressor has become increasingly active, and many countries and enterprises have begun to explore the road of oil-free screw air compressor on the basis of the original oil-injected screw air compressor. In the field of high gas quality requirements, such as textile, metallurgy, food, chemical industry, medicine, petroleum and air separation and other places that need pure oil-free compressed air, oil-free screw air compressor can provide high-quality compressed gas to meet various needs, so the application prospect is broad.

Application field of water-lubricated oil-free screw air compressor

oil-free screw air compressor classification and major manufacturers oil-free screw air compressor including dry screw air compressor and water lubrication screw air compressor two categories. The dry screw air compressor is mainly a twin screw air compressor, and the water jet screw air compressor includes a twin screw air compressor and a single screw air compressor.

In the food manufacturing and packaging industry, when the oil-injected screw air compressor is used to prepare compressed gas, the performance of the lubricating oil in the air compressor has been greatly reduced and acidic after many times of high-temperature oxidation and condensation emulsification in the production process, which not only fails to lubricate the subsequent equipment, but also destroys the normal lubrication. The use of oil-free screw air compressor can avoid the negative impact of failed lubricating oil on the equipment.

in pharmaceutical and biological engineering, the pollution of bacteria and bacteriophage in compressed gas can not be ignored. The pure compressed gas provided by oil-free screw air compressor can avoid the breeding of bacteria and bacteriophage in the gas.

In the electroplating industry, there are some problems in the production process, such as the surface of the coating, burning, pinhole, crack and so on. Therefore, oil-free screw compressors have been used to prepare pure gas for electroplating.

In the automotive spray industry, impure gases often result in inferior coatings. If the compressed air contains oil, there are some scattered or concentrated small bumps on the surface of the coating. These blisters are generally produced in a coating under the topcoat. The blisters are caused by water vapor or pollutants under the coating. In addition, oily compressed air may also lead to the appearance of dot-like distribution of small potholes on the surface of the wet coating, forming crater-like silica pits, and sometimes visible substrates at the bottom of the pits, commonly known as fish eyes. Nowadays, the automobile spraying industry has begun to apply oil-free screw air compressors to prepare pure gas for spraying, so that the spraying level of domestic automobiles has been improved.

In the textile industry, air-jet looms require dry and oil-free compressed air. In the production process, the fine nozzle will blow compressed air to the line to form a vortex, thereby giving the yarn shape, elasticity and elasticity. The pure compressed air provided by the oil-free screw air compressor can ensure the quality of the finished cloth.
