  • The air storage tank is also one of the important parts of the air compressor. Its role in the air compressor system is: buffering, making the air supply more stable, reducing the frequent startup of the air compressor, and letting compressed air in the air storage tank Precipitation, in order to facilitate the dewatering and decontamination of the gas storage tank. So, what are the basic requirements for the selection of air storage tanks? 1. The volume of the air compressor storage tank should be controlled within the range of 10%-20% of the compressor displacement. We generally choose 15%. When the air volume is large, the volume of the air storage tank is also required. Properly increase, if the on-site gas consumption is small, it can be less than 15%, preferably not less than 10%. 2. The processing capacity of the filter and dryer should be consistent with the discharge capacity of the compressor. 3. The filter before the dryer should be equipped with an automatic drain. 4. When using an adsorption dryer, the compressor should reserve corresponding air consumption. 5. The dryer is installed before the gas storage tank, and the system can provide a larger peak ad

  • As the main air source for machinery manufacturing, screw air compressors have been widely used in all walks of life. But, do you know the structure principle and main features of screw air compressor? 1. The working cycle of a screw air compressor can be divided into three processes: suction, compression and exhaust. As the rotor rotates, each pair of mutually meshing teeth completes the same work cycle one after another. 2. Compared with ordinary air compressors, screw air compressors have different characteristics and advantages. how to say? Please see the following summary of the suction process, compression process and exhaust process of the screw air compressor. Inhalation process: When the rotor rotates, the tooth groove space of the main and auxiliary rotors is turned to the opening of the inlet end wall, and the space is relatively large. At this time, the tooth groove space of the rotor is connected with the free air of the air inlet. The air is sucked into the enclosed cavity composed of the yin and yang rotor and the shell. When the air fills the entire tooth groove, the air inlet end face of the rotor turns away from the air inlet of the casing, and the air between the tooth grooves is closed. Compression process: As the rotor rotates, the volume between the teeth decreases continuously due to the meshing of the rotor teeth. The volume occupied by the gas enclosed

  • From the point of view of oil content, the oily and non-oily air compressors generally refer to the oil content of the air discharged from the exhaust port of the air compressor. Generally, the oil content of oil compressors is relatively large, and the oil content of oil-free machines is 0.01ppm, so this oil content can be used to distinguish whether the air compressor is oily or oil-free. There is also a completely oil-free air compressor, which is not lubricated with oil, but with resin material lubrication, so the final gas discharged without oil is called a completely oil-free air compressor. From the structural point of view, the bearings of oil-free air compressors and oil-free air compressors are not much different. But in terms of working principle, there are obvious differences between the two. No oil is involved in the operation of oil-free air compressors, whether it is an oil-free piston engine or an oil-free screw compressor, they will generate a lot of high temperature during operation. If it is an air compressor with oil, the participation of oil will take away the high temperature generated during the compression process of the air compressor, thereby cooling the machine. However, oil-free air compressors do not have the participation of oil, and a large amount of high temperature is also generated during the compression process. How to solve the high temperature of the compressor to ensure the normal operation of the machine? In fact, oil-free air compressors use a kind of Teflon Or the special high-temperature resistant material of molybdenum disulfide replaces oil to solve the high temperature in the air compressor
