2. How to maintain and replace the common accessories of air compressor?
1. 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.
If the air filter element is clogged and damaged, a large number of particles larger than the allowable size will enter the screw machine and circulate, which will not only greatly shorten the service life of the oil filter element and the 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. 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. It is best to add screw oil before installing the new filter element.
It is recommended to replace the new filter element every 1500-2000 hours. It is best to replace the oil filter element at the same time when changing the engine 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 dirt and particles will directly enter the screw host with the oil, causing serious consequences.
Misunderstanding: It is not that the filter with the higher filter precision is the best, but that it is the best to choose the appropriate air compressor filter.
Filter accuracy refers to the maximum diameter of solid particles that can be blocked by the air compressor filter element. The higher the filtration accuracy of the filter element, the smaller the diameter of the solid particles that can be blocked, and the easier it is to be blocked by large particles.
When selecting an air compressor filter, choosing a high-precision air compressor filter regardless of the occasion cannot guarantee the filtration efficiency of the air compressor filter (related to the penetration rate, which is the most important factor to measure the quality of the air compressor filter standard), and the service life will also be affected. The filtering accuracy should be selected according to the filtering object and the purpose achieved.
3. Separator
The oil-gas separator is a component that separates the lubricating oil from the compressed air. Under normal operation, the service life of the oil-gas 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. The oil and gas separator must be replaced when it expires or the pressure difference between the front and back exceeds 0.12MPa. Otherwise, the motor will be overloaded, and the oil-air separator will be damaged and oil will leak out.
When replacing the separator, the control pipe joints installed on the oil and gas barrel cover should be removed first, then the oil return pipe extending into the oil and gas barrel from the oil and gas barrel cover should be removed, and the fastening bolts on the oil and gas barrel cover should be removed. 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.
Finally, install a new oil and gas separator. Note that the upper and lower asbestos pads must be stapled and stapled. When pressing, the asbestos pads must be placed neatly, otherwise it will cause pad flushing. Reinstall the upper cover plate, oil return pipe, and control pipes as they were, and check for leaks.
