Screw air compressor as a wide range of general machinery, is used in all aspects of production. According to the different lubrication methods can be divided into oil-free air compressor and 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 contains less oil, 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 water lubrication, so the discharge of the 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. How to reduce the occurrence of high temperature failure?
In fact, the oil-free air compressor uses water to replace the oil to solve the high temperature in the air compressor compression process, 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.
When starting the air compression system, it is usually recommended to turn on the air compressor first, and then turn on the dryer. This is because the air compressor is the source of compressed air, and only by starting the air compressor first can compressed air be generated for the dryer to process. If you turn on the dryer first, and not
Special air compressors for the environmental protection industry are widely used in the environmental protection industry, mainly for the following aspects: Sewage treatment: In the sewage treatment process, the air compressor can provide gas to increase the oxygen content, which helps bacteria more effectively Degradation of sewage
Scroll air compressor and screw air compressor have their own advantages and applicable scenarios, the specific choice of which type depends on the actual needs and the use of the environment. The following is a comparative analysis of the two air compressors: 1. scroll air compressor Advantages: simple structure
Screw air compressor can work continuously without stopping, especially some specific models, such as water-lubricated oil-free screw air compressor, can run for a long time. When the pressure reaches the set value, the air compressor can automatically stop, and the permanent magnet variable frequency air compressor will run at low speed. In addition, the snail
The reasons for the slow air intake of the screw air compressor may involve many aspects. The following is a detailed analysis of these possible reasons: First, there may be problems with the air intake filter of the air compressor. If the filter is too dirty or blocked, it will severely limit the inflow of air, resulting in
There are significant differences between screw and scroll compressors in terms of structure, working principle, performance characteristics and application fields. The following is a detailed comparison of the two: 1. working principle and structure Screw compressor Scroll compressor
The frequency conversion screw machine can work continuously in theory. This type of air compressor is designed to run for a long time, and usually has a twenty-four hour operation capacity. When the air pressure is insufficient, the air compressor will automatically load, and when the air pressure reaches the preset value, it will automatically load.
When choosing an air compressor, oil-free air compressor and oil-free air compressor have their own advantages and disadvantages, and the specific choice depends on the application requirements and working environment. Oil-free air compressor: Advantages: The compressed air produced is completely oil-free, suitable for high air quality requirements
The oil content of oil-free air compressors is usually 0.01ppm. This is a very low oil content, so that the air produced by the oil-free air compressor during the compression process is almost free of oil. In some special applications, such as hospitals, laboratories, schools and other institutions, due to the air
The buffer tank of the air compressor belongs to the pressure vessel. The buffer tank is one of the important parts of the air compressor. Its main function is to reduce the pulsation in the exhaust process of the air compressor, convert the pressure energy of the gas into kinetic energy, and reduce the vibration of the pipeline. To achieve this effect, the buffer tank
