1、 Methods to extend the service life of oil-free air compressors:
Firstly, according to the operating procedure of the oil-free air compressor equipment, most of the shutdown work is carried out, and the normal shutdown procedure is opposite to the startup procedure. Just gradually reduce the speed to a very low speed. Fully open the exhaust branch valve, fully close the exhaust valve, turn off the driver, and confirm that the entire series of air compressor equipment will gradually stop automatically. The supply of cooling water cannot be stopped within 30 minutes after the equipment stops.
Secondly, after completing the operation of the oil-free air compressor equipment, attention should be paid to checking the cutting at each level and the fit between the cutting parts and the cutting body. If there are cracks on the cutting piece, please replace it with a spare part. Check the front cover of each level of cylinder, check the friction force of the cylinder mirror surface, and identify the cause if there are friction marks. Check the friction between the cross slide and the friction surface using the body guide rail. Remove the connecting rod big head bushing and crosshead pin, and check the friction force of the friction surface.
Similarly, it is necessary to check whether the oil level indicated by the oil level indicator of the oil-free air compressor meets the requirements. And the connection and fixation of connectors. If there is any looseness, please fix it in time. Observe and judge whether the moving parts are flexible. Rotate the flywheel by hand to idle the oil-free air compressor two or three times. In case of paper jam and collision.
Then, pay attention to checking the quality of the lubricating oil in the oil-free air compressor and replacing the lubricating oil in the machine body. After the initial operation of the oil-free air compressor, a large amount of metal powder enters the lubricating oil due to the running in of the parts and the cleaning effect of the lubricating oil. Therefore, all lubricating oil should be replaced after 24 hours of operation. After running for 200 hours, change the oil again. After two replacements, please replace the engine oil according to routine maintenance requirements.
2、 Maintenance and upkeep of the main components of oil-free air compressors:
1. When repairing and replacing various components according to the above table, it must be confirmed that the pressure inside the oil-free air compressor system has been released, isolated from other pressure sources, the switch on the main circuit has been disconnected, and safety signs prohibiting closing have been made:
The replacement time of compressor cooling lubricating oil depends on the usage environment, humidity, dust, and whether there are acidic or alkaline gases in the air. The newly purchased oil-free silent air compressor needs to be replaced with new oil after the first 500 hours of operation. From now on, it should be replaced every 4000 hours according to the normal oil change cycle. Machines that operate for less than 4000 hours per year should be replaced once a year;
3. The oil filter must be replaced after 300-500 hours of operation during the first start-up, and after 2000 hours of use, it should be replaced every 2000 hours according to normal time thereafter
4. When repairing or replacing air filters or intake valves, remember to prevent any debris from falling into the compressor main chamber. Close the entrance of the host during operation. After operation, rotate the host several times in the direction of rotation by hand to ensure there are no obstacles before turning it on.
5. Check the tightness of the belt every 2000 hours of machine operation. If the belt is loose, adjust it until it is tightened; To protect the belt, it is necessary to prevent it from being scrapped due to oil contamination throughout the entire process;
6. When changing the oil, the oil filter must be replaced at the same time
