Air filter replacement time Air filter replacement time is greatly affected by the surrounding environment. Due to the geographical location of Dagang Oilfield, the wind and sand is relatively large, the air filter is easy to block, and it needs to be regularly inspected and replaced. According to the experience of several years, the air The filter needs to be checked once every 500h. The step of cleaning the air filter is to gently tap the two end faces of the filter element against a flat surface to remove most of the heavy dry dust, and then blow it out from the inside of the air filter element with 23 kg/cm 2 of dry air. The purged pipe is at least 30 mm away from the folded paper to prevent the folded paper from being blown. After several purgings of the air filter, the new air filter needs to be replaced after the running time reaches 2000h.

Oil and gas separator filter replacement time The oil separator filter needs to be replaced with a new filter after 8000h. Before replacing, remove the oil return pipe on the compressor, loosen the screw of the top cover of the oil separator, remove the top cover, carefully lift the oil separator filter and take it to the outside of the cylinder to check whether the sealing ring of the top cover and the cylinder is damaged. A new seal must be replaced for damage. After installing the new filter element, tighten the nut to prevent leakage of the top cover and the barrel seal, and connect the return line.

Lubricating oil inspection and replacement of the GA22P10 screw compressor if using the Atlas supplied by the manufacturer. Copco special oil, can be replaced every 4000h. The air-cooler fin cleaning GA22P10 screw compressor uses air cooling, which requires regular cleaning of the fin dust. If the fins are not blown, the heat dissipating surface is covered by dust, which affects the cooling effect, causing the temperature of the oil and gas to rise. When the exhaust gas temperature exceeds 110, the unit will give an alarm. The dust of the fins can be blown with dry air. If the fins are oily, the fins need to be removed from the machine and the fins cleaned with solvent.

Concluding remarks (1) Strengthen the fine management of air compressors, formulate practical reward and punishment measures to improve the enthusiasm and responsibility of post operators; (2) Strengthen the daily operation adjustment and maintenance of air compressors, and do daily maintenance of unit operation Work, find the hidden dangers and solve them in time.
