Regular maintenance of air compressor

Regular maintenance of air compressor plays an important role in service life and operation reliability

Maintenance of air filter: the air filter is a part to filter the air dust and dirt, and the filtered clean air enters the screw rotor compression chamber for compression. Because the internal clearance of screw machine only allows particles within 3 μ m to filter out. If the air filter element is blocked and damaged, a large number of particles larger than 3 μ m will enter into the internal circulation of the screw machine, which will not only greatly shorten the service life of the oil filter element and the oil-gas separation core, but also cause a large number of particles to directly enter the bearing cavity, accelerate the bearing wear, increase the rotor clearance, reduce the compression efficiency, and even kill the rotor. Therefore, it is very important to replace the air filter element.

Maintenance of oil filter: it is strictly forbidden to use the oil filter element beyond the time limit. Otherwise, due to the serious blockage of the filter element and the pressure difference exceeding the bearing limit of the bypass valve, the bypass valve will open automatically, and a large number of dirt and particles will directly enter the screw main engine with the lubricating oil, causing the wear of the main engine.

Maintenance of oil-gas separation filter element: oil-gas separator is a component to separate screw lubricating oil and compressed air, so the separation core must be replaced every other year or when the monitor pressure difference alarm.

Maintenance of lubricating oil: the quality of the lubricating oil has a decisive impact on the performance of the air compressor. Please make sure to use the original accessories of the factory to ensure the operation stability and maximize the operation life of the unit; when the oil temperature is above 60 ℃, the viscosity will be reduced and will not be hot, and the residual oil of the unit will be drained. Therefore, when changing the oil, if the oil is cold, start the machine and run for 2-3 minutes to heat the oil before changing it.
