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.
Contact information of oil-free air compressor manufacturers: At present, the main brands of oil-free air compressors in China are Granklin and so on.
Principle of screw air compressor 1. Suction process: The screw-type intake side suction port must be designed so that the compression chamber can fully inhale, and the screw compressor does not have an intake and exhaust valve group. The opening and closing of a regulating valve is adjusted, when the rotor
Oil air compressor refers to the use of lubricating oil (synthetic oil or semi-synthetic oil) in the air compressor system to lubricate the machine and dissipate heat. This kind of air compressor, the compressed air will have a certain amount of lubricating oil, that is, the post-processing equipment is used for filtration, but it will still have
Oil-free air compressor, Granklin Group is engaged in the production of products. As one of the main products in the air compressor manufacturing industry, oil-free air compressor has been recognized by many customers. Many customers in the purchase of air compressors are as one of the campaign goals, so what are the advantages of oil-free air compressors?
Granklin water lubricated air compressor has a reasonable structure and an ideal force balance: both sides of the screw of the oil-free air compressor are equipped with a star wheel symmetrical structure, so that the oil-free air compressor not only has no unbalanced inertial force, but also The axial force and radial force on the screw cancel each other out, making it have an ideal force balance.
With the blockade of China's high-tech technology and equipment by the United States in recent years, such as the recent mention of advanced technology and equipment used in the semiconductor and chip industries: Japan's Shin-Yue, the United States Dow, Asmai, etc. However, the realization of the semiconductor and chip industry's gradual national
The medical air compressor must be controlled within 60 decibels, and the sound of the general household air-conditioning compressor (about 55 decibels), medical staff will not feel uncomfortable working in such an environment. In view of the relatively quiet environment required by the hospital, air compressors with noise higher than 60 decibels cannot be used in hospitals.
View detailsScrew compressor-is a rotary positive displacement compressor, in which two rotors with spiral gears mesh with each other, so that the volume of the two rotors meshing from large to small, thereby compressing and discharging the gas. Screw pressure in screw air compressors
Oil-free screw air compressors are divided into two types, one is a dry oil-free screw air compressor, and the other is a water lubricated oil-free screw air compressor. 1. dry oil-free screw air compressor is also called oil-free screw air compressor, mostly twin screw air compressor, refers to the rotor
1. operators must be familiar with the structure, performance, working principle, operating procedures and precautions of the air compressor. 2. operators must undergo technical training and safety training, and after passing the examination, they shall take up their posts with certificates and shall not operate without certificates.
