Maintenance of screw air compressor filter element

Maintenance of screw air compressor filter element

In production, air compressors are still widely used and can be seen almost everywhere. However, at present, most air compressors have a lot of energy waste, especially in the air compressor filter element. Through reasonable management, it can help enterprises save energy consumption every year, and can indirectly reduce CO2 emissions. economic, environmental and social benefits. In the daily troubleshooting of the air compressor, the common faults are high exhaust temperature and high fuel consumption, and the common causes of high exhaust temperature are the blockage of the oil filter element, the use of air compressor oil overtime and The surface of the cooler is too dirty or blocked, and the common cause of high oil consumption is the rupture of the oil filter element. Among them, the oil filter element and the oil fine separator element are all vulnerable spare parts of the air compressor. In addition, there are air filter elements, and the air compressor oil needs to be replaced regularly.

(1) The recommended running time of the air filter element is 1500h, and it needs to be cleaned regularly. Generally, it should be purged once every 2 to 4 weeks, and an air source below 2kg should be used for purging.

(2) It is recommended to run the air compressor oil for 2000h for sampling and analysis, and decide whether to replace it according to the test results.

(3) It is recommended to replace the oil filter element after running for 3500h, or when the oil injection pressure is lower than 0.25mpa.

(4) It is recommended to replace the oil filter element after running for 5000h, or if the oil partial pressure difference exceeds 0.055mpa, it is recommended to replace it. The air compressor filter element is the core component of the filter. It is made of special materials and is a wearing part. It needs special maintenance and maintenance. When the filter has been working for a long time, the filter element has intercepted impurities, which will cause pressure When the flow rate increases, the flow rate decreases, so it needs to be cleaned in time; when cleaning, be careful not to deform or damage the filter element.

Generally, the service life of the filter element is different according to the different raw materials used, but with the extension of the use time, the impurities in the water will block the filter element, so generally speaking, the PP filter element needs to be replaced in three months; the activated carbon filter element needs to be replaced in six months. ; The fiber filter element is generally placed at the back end of the PP cotton and activated carbon because it cannot be cleaned, which is not easy to cause blockage; the ceramic filter element can usually be used for 9-12 months. The filter paper in the equipment is also one of the keys. The filter paper in the filter equipment is usually made of ultra-fine fiber paper filled with synthetic resin, which can filter impurities and has strong dirt storage capacity. According to relevant statistics, a passenger car with an output power of 180 kilowatts travels 30,000 kilometers, and the impurities filtered out by the filter equipment are about 1.5 kilograms. In addition, the equipment also has great requirements for the strength of the filter paper. Due to the large flow of air, the strength of the filter paper can resist the strong airflow, ensure the efficiency of filtration, and prolong the service life of the equipment.
