After a period of use, the oil-free air compressor needs to be regularly inspected and maintained, from start-up to operation to check materials, and finally regularly carry out component maintenance, which can help extend the service life of the oil-free air compressor.

1. Ways to extend the service life of oil-free air compressors: First, according to the operating procedures of oil-free air compressor equipment, most of them are closed, and the normal shut-off procedure is the opposite of the start-up procedure. Simply gradually reduce the rpm to a very low speed. Open the exhaust branch valve completely, close the exhaust valve completely, close the drive engine, and confirm that the entire series of air compressor equipment will gradually stop automatically. The cooling water supply cannot be stopped for 30 minutes after the equipment is stopped.

Secondly, after completing the operation of the oil-free air compressor equipment, pay attention to checking the cutting at all levels and check the cooperation between the cutting parts and the cutting body. If there are cracks in the cutting pieces, replace them with spare parts. Check the front cover of each level of cylinder, check the friction of the cylinder mirror, and find out the cause if there are friction marks. Check the friction between the cross sliding plate and the friction surface with the fuselage guide. Remove the connecting rod head bushing and crosshead pin, and check the friction 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 fastening of the connectors. If there is looseness, fix it in time. Observe and judge whether the moving parts are flexible. Turn the flywheel by hand to make the oil-free air compressor idle two or three times. In case of paper jams and collisions.

Then, pay attention to check the quality of the lubricating oil of the oil-free air compressor and replace the lubricating oil in the fuselage. After the initial operation of the oil-free air compressor, a large amount of fine metal powder enters the lubricating oil due to the running-in of parts and the cleaning effect of lubricating oil. Therefore, all lubricants should be replaced after 24 hours of operation. After 200 hours of operation, change the oil again. After two changes, change the oil according to routine maintenance requirements.

2. Maintenance of the main components of oil-free air compressor:

1. When repairing and replacing each component according to the above table, it must be determined that the pressure in the oil-free air compressor system has been released, separated from other pressure sources, the switch on the main circuit has been disconnected, and the safety sign of not closing has been made.

2. The replacement time of compressor cooling lubricant depends on the use environment, humidity, dust and whether there are acid and alkaline gases in the air. The newly purchased oil-free silent air compressor must be replaced with new oil for the first 500 hours of operation, and then replaced every 4000 hours according to the normal oil change cycle, and the machine with an annual operation of less than 4000 hours should be replaced once a year.

3. The oil filter must be replaced in the first 300-500 hours of operation, the second time in 2000 hours of use, and then every 2000 hours according to normal time;

4. When repairing and replacing the air filter or intake valve, remember to prevent any debris from falling into the compressor main chamber. After the operation is completed, rotate the main engine several times according to the direction of rotation of the main engine with your hand to make sure that there is no obstruction before you can start the machine;

5. Check the tightness of the belt every 2000 hours of operation of the machine, if the belt is loose, adjust it until the belt is tightened; In order to protect the belt, it is necessary to prevent the belt from being scrapped due to oil contamination during the whole process;

6. The oil filter must be replaced at the same time every time the oil is changed.
