How to maintain oil-free air compressor

after the oil-free air compressor is used for a period of time, it needs regular inspection and maintenance, from start-up to operation to inspection of materials, and finally to carry out regular parts maintenance, which can help to prolong the service life of the oil-free air compressor. The following editor will explain in detail, what are the main precautions, let's take a look!

1. methods to extend the service life of oil-free air compressor:

first of all, according to the oil-free air compressor equipment operating procedures, most of the shutdown work, the normal shutdown procedure is the opposite of 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 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 piece and the cutting body. If there is a crack in the panel, replace it with a spare part. Check the front cover of each level of cylinder, check the friction of the cylinder mirror, if there are traces of friction, find out the cause. Use the fuselage track to check the friction between the cross slide and the friction surface. Remove the connecting rod big end 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 fixing of the connecting parts. If it is loose, please fix it in time. Observe and judge whether the moving parts are flexible. Rotate the flywheel by hand to make the oil-free air compressor idle twice or three times. In case of paper jams and collisions.

Then, pay attention to check the quality of the oil-free air compressor lubricating oil and replace the lubricating oil in the fuselage. After the first operation of the oil-free air compressor, a large amount of metal fine powder enters the lubricating oil due to the running-in of the parts and the cleaning effect of the 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.

How to maintain an oil-free air compressor to help extend its service life?

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

1. When repairing and replacing each component according to the above table, it must be confirmed 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 mark of closing is not allowed;

2. The replacement time of compressor cooling lubricating oil depends on the use environment, humidity, dust and whether there is acid and alkaline gas in the air. Newly purchased oil-free silent air compressor shall 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. Machines with annual operation less than 4000 hours shall be replaced once a year;

3. The oil filter must be replaced for 300-500 hours at the first startup, 2000 hours at the second time, and then replaced every 2000 hours at the normal time;

4. Maintenance and replacement of air filter or intake valve remember to prevent any debris into the compressor host cavity. When operating, the entrance of the host is closed. After the operation is completed, rotate several circles by hand according to the rotation direction of the host to make sure that there is no obstacle before starting up;

5. Check the tightness of the belt every 2000 hours or so of the machine. If the belt is loose, adjust it until the belt is tight. In order to protect the belt, it is necessary to prevent the belt from being scrapped due to oil pollution during the whole process;

6. Every time the oil is changed, the oil filter must be replaced at the same time;
