Screw air compressor as a wide range of general machinery, is used in all aspects of production. According to the different lubrication methods, it can be divided into oil-free air compressor and oil-free air compressor. What is the difference between the two?
1. to different oil contents, oil-free and oil-free air compressors generally refer to the oil content of the gas discharged from the exhaust port of the air compressor. Generally, oil-free air compressors have a large oil content. Oil-free oil is not free, but the oil content is relatively small, about 0.01ppm. Therefore, this oil content can be used to distinguish oil-free and oil-free air compressors. There is a full oil-free air compressor, it is not the use of oil lubrication, but the use of resin material lubrication, so the exhaust gas does not contain oil called oil-free air compressor.
2. works differently. From a structural point of view, there is no difference between the bearings of oil-free air compressor and oil-free air compressor. But from the working principle, there are obvious differences between the two. Oil-free air compressor in the process of operation is not involved in the oil, whether it is oil-free piston machine or oil-free screw air compressor, they will produce a lot of high temperature in the process of operation, if there is oil air compressor oil The participation will take away the high temperature generated in the compression process of the air compressor, thereby cooling the machine.
3. oil-free air compressor is not involved in the oil, and in the process of compression may produce a lot of high temperature, easy to cause high temperature failure. In fact, the oil-free air compressor uses a special high temperature resistant material called Teflon or molybdenum disulfide, which replaces the oil to solve the high temperature in the compression process of the air compressor, thus achieving the purpose of oil-free compression.
Oil-free air compressor because of its water to lubricate the compressed gas is cleaner than the oil injection air compressor. So the food, medical and other industries often use oil-free screw air compressor.
The main difference between air compressor power frequency and frequency conversion is reflected in the following aspects: 1. start characteristics power frequency air compressor start mode: usually use direct start or star triangle step-down start. Starting current: the starting current is large, generally 5 to 7 times of the rated current, which is very important for the power grid.
Granklin water lubricated screw air compressor cooling system configuration shows that Granklin water lubricated screw air compressor adopts innovative water lubrication technology to realize lubrication and cooling of compression cavity through water film. In response to users' doubts about whether the equipment needs to be equipped with water towers
If the oil-free air compressor does not stop and continue to run, the following situations may occur: The temperature is too high: During the long-term operation of the oil-free air compressor, the internal temperature of the machine will rise due to the pressure generated by friction and compression. Excessive temperature will damage the inside of the machine
During the operation of the air compressor, condensed water will be generated due to air compression and temperature changes. If it is not properly treated, it may cause pipeline corrosion, equipment wear and pollution at the gas end. The following from the moisture generation mechanism,
Medical air compressor is the key equipment used to provide compressed air in the medical field Secondary specialized school door. Its core function is to provide stable, clean and medical standard compressed air for all kinds of medical equipment, surgical operation, ward nursing and hospital infrastructure. The following is medical.
The main difference between the power frequency and frequency conversion of the air compressor lies in the operation control mode and energy efficiency performance, which directly affects the applicable scene and energy saving effect of the equipment. The power frequency air compressor is driven by a fixed frequency power supply, and the motor runs at a constant speed. The output of compressed air is determined by starting and stopping or
In food enterprises, compressed air is an important "role", it is like a "little assistant" on the food production line, helping our food to be better produced. However, this little assistant also has to abide by some"
Air compressor with water is a common problem, which may affect the quality of compressed air and the normal operation of equipment. The following is the general method to deal with the water in the air compressor: check and exclude the external water source: make sure that the air inlet of the air compressor is not covered by rainwater or its
Compressed air regulations and standards mainly refer to national or regional regulations, codes and standards related to the design, installation, operation, maintenance and safety of compressed air systems. These standards are designed to ensure the energy efficiency, reliability, safety and safety of compressed air systems.
Permanent magnet frequency conversion screw air compressor integrates a variety of advanced technologies, showing many significant advantages: high efficiency and energy saving: permanent magnet frequency conversion technology enables the motor to maintain high efficiency during operation and reduce energy waste. Through frequency conversion control, the air compressor can be based on the actual
