Correct use of air compressor three filter maintenance method

The maintenance method of the three filters of the air compressor:

Air compressor brands: Atlas, Ingersoll Rand, Sullair, Fusheng, Fidelity, Compair, etc.

 

The three filters of the air compressor mainly refer to the air filter, oil filter, and oil-gas separator. Routine maintenance has a great impact on the service life and maintenance cost of the air compressor.

Xinxiang Lifelt filter reminds you that the maintenance of the three filters of the air compressor mainly pays attention to the following items:

1. Maintenance of intake air filter

 

        The air filter is a component that filters out air dust and dirt, and the filtered clean air enters the screw rotor compression chamber for compression. Due to the internal clearance of the screw machine, only particles within 15u are allowed to filter out. If the air filter element is clogged and damaged, a large number of particles larger than 15u will enter the internal circulation of the screw machine, which will not only greatly shorten the service life of the oil filter element and oil-fine separator, but also cause a large amount of particles to directly enter the bearing cavity, which will accelerate bearing wear and increase the rotor clearance. The compression efficiency is reduced, and even the rotor is dry and seized.

2. Maintenance of oil filter

 

        After the new machine runs for 500 hours for the first time, the oil element should be replaced, and the oil filter element should be removed by reverse rotation with a special wrench. Before installing the new filter element, it is better to add screw oil. It is recommended to replace the new filter element every 1500-2000 hours. It is better to replace the oil filter element at the same time when changing the oil. When the environment is harsh, the replacement cycle should be shortened. It is strictly forbidden to use the oil filter element beyond the time limit, otherwise, due to the serious clogging of the filter element, the pressure difference exceeds the tolerance limit of the bypass valve, the bypass valve will automatically open, and a large amount of stolen goods and particles will directly enter the screw host with the oil, causing serious consequences. The replacement of the diesel engine oil filter element and the diesel filter element of the diesel-driven screw engine should follow the maintenance requirements of the diesel engine, and the replacement method is similar to that of the screw engine oil element.

 

3. Maintenance of oil and gas separator

        The oil-air separator is a component that separates the screw lubricating oil from the compressed air. Under normal operation, the service life of the oil-air separator is about 3000 hours, but the quality of the lubricating oil and the filtration accuracy of the air have a huge impact on its life. It can be seen that the maintenance and replacement cycle of the air filter element must be shortened in harsh operating environments, and even the installation of a front air filter must be considered. It must be replaced after exceeding 0.12Mpa. Otherwise, the motor will be overloaded, and the oil-air separator will be damaged and oil will leak out.

 

Replacement method: Remove the control pipe joints installed on the oil and gas barrel cover. Take out the oil return pipe extending into the oil and gas barrel from the cover of the oil and gas barrel, and remove the fastening bolts of the upper cover of the oil and gas barrel. Remove the upper cover of the oil and gas barrel, and take out the oil. Remove the asbestos pad and dirt stuck on the upper cover. Install a new oil and gas separator, pay attention to the upper and lower asbestos pads must be stapled and stapled, and the asbestos pads must be placed neatly when pressing, otherwise it will cause pad flushing. Reinstall the upper cover plate, oil return pipe, and control pipes as they were, and check for leaks.
