Precautions for maintenance of compressed air supply system

①A dust filter must be installed at the air inlet of the compressor

Since all the air entering the compressor must pass through the air inlet of the compressor, in order to prevent tiny particles of various solid impurities and corrosive dust from entering the cylinder of the compressor, causing excessive wear on the inner wall of the cylinder, piston rings and valves, it is necessary to Install a dust filter at the air inlet of the compressor. The filter element of the dust filter is made of microporous material or felt material with strong adsorption capacity. Commonly used felt filter materials include acrylic fiber, polyester staple fiber filter cotton, glass fiber, coconut palm, activated carbon, honeycomb paper material, etc., which can ensure that small dust particles and abrasive debris in the air will not enter the cylinder of the compressor. This prevents excessive wear of cylinder walls, piston rings and pistons. It can also be used in combination with the dust filter and the muffler, which not only reduces the pollutants in the air, but also eliminates the noise generated at the air inlet. In addition to felt filters, sieve filters and Oil Bath filters can also be used. In order to improve the filtration efficiency of the sieve filter, the filter screen should be soaked in oil to make the screen have a certain viscosity, and dust and other particles will be stuck when passing through the filter screen. The Oil Bath filter is to let the air pass through the oil or pass through the oil surface to filter out the dust. In order to maintain the efficiency of the filter, the filter should be cleaned and replaced frequently.

②The volume of the air storage container used with the Air Compressor should be appropriate

If the volume is too small, the compressor will start frequently, if it is too large, it will take up a lot of space unnecessarily, and the compressor will have to work for a long time to make it reach the required pressure.

③The distribution system is the key to the connection of the compressed air system

The distribution system includes flexible hoses or fixed pipes, joints, valves, air filters, oil-water separators, air pressure regulators, instrument lubricators and other air control devices of appropriate specifications. It must be carefully checked regularly to make their performance meet the requirements. requirements . The pipes and accessories connecting the compressor and the gas storage container must withstand pressure. For gas pipelines that do not need to be moved, it is generally better to use copper pipes or galvanized iron pipes. If the compressor needs to be lubricated with oil, the air hose used must not only be pressure-resistant, but also oil-resistant.
