How to prolong the service life of oil-free air compressor

After using the oil-free air compressor for a period of time, regular inspection and maintenance are required from start-up to operation and then to material inspection, which can finally help extend the service life of the oil-free air compressor. The following editor will explain in detail what are the key points that need to be paid attention to? let's see!

First, the method of extending the service life of the oil-free air compressor:

First of all, according to the operating procedures of oil-free air compressors, most of the shutdowns are working, 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 bypass valve, fully close the exhaust valve, turn off the driving machine, and confirm that the entire series of air compressor equipment will gradually and automatically stop. Do not stop the cooling water supply within 30 minutes after the equipment stops.

Secondly, after completing the operation of the oil-free air compressor, pay attention to check the coordination between the cutting at all levels and the cutting parts and the cutting body. If the cut part is cracked, replace it with a spare part. Check the front cover of each horizontal cylinder, check the friction of the cylinder mirror, if there are traces of friction, find out the reason. Check the friction between the cross slide and the friction surface of the fuselage rail. Remove the connecting rod 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 connector. If it is loose, please repair it in time. Observe and judge whether the moving parts are flexible. Turn the flywheel to the oil-free air compressor position two or three times by hand. To prevent 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 oil-free air compressor runs for the first time, due to the running-in of the parts and the cleaning effect of the lubricating oil, a large amount of fine metal powder enters the lubricating oil. Therefore, after 24 hours of operation, all lubricating oil should be replaced; after 200 hours of operation, the oil should be changed again, and after two oil changes, please change the oil according to the routine maintenance requirements.

Second, the maintenance of the main components of the oil-free air compressor:

1. When repairing and replacing various components according to the above table, it must be confirmed that the pressure in the oil-free air compressor system has been released, isolated from other pressure sources, the switch on the main circuit has been closed, and a safety sign that does not allow closing has been made ;

2. The replacement time of compressor cooling lubricating oil depends on the use environment, humidity, dust and whether there is acid-base gas in the air. Newly purchased oil-free silent air compressors must be replaced with new oil after 500 hours of operation for the first time, and then replaced every 4000 hours according to the normal oil change cycle, and replaced once a year for machines with less than 4000 hours of annual operation;

3. The oil filter must be replaced after 300-500 hours of operation for the first time, and after 2000 hours of use for the second time, it should be replaced every 2000 hours in normal time thereafter;

4. When repairing and replacing the air filter or intake valve, remember not to let any sundries fall into the main chamber of the compressor. During operation, close the host entrance. After the operation is finished, turn the host in the direction of rotation several times by hand, and then turn it on after confirming that there are no obstacles.

5. When the machine is running, check the tightness of the belt about every 2000 hours. If the belt is loose, the belt must be adjusted until the belt is tensioned; in order to protect the belt, it is necessary to prevent the belt from being scrapped due to oil pollution;

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