Since its birth, screw air compressor has been accepted by the majority of users because of its high efficiency and energy saving characteristics. The daily maintenance of air compressors is a matter of concern to users, so what problems need to be paid attention to in the use of bearing grease?

(1) had a refill of lubrication to the appropriate

If the amount of fat is too large, the friction torque will increase, the temperature will increase, and the fat consumption will increase. However, if the amount of grease is too small, it can not obtain reliable lubrication and dry friction occurs. Generally speaking, the appropriate amount of grease is 1/3 ~ 1/2 of the total void volume in the bearing. However, depending on the situation, sometimes the bearing edge should be coated with grease to perform cavity lubrication.

(2) Take care to prevent the mixing of different types, grades and new greases

Avoid the cross use of grease containers and tools, otherwise, it will have adverse effects on the grease drop point, cone penetration and mechanical stability decline.

( 3 ) attaches great importance to the new grease work

Because the varieties and quality of lubricating oils are constantly improved and changed, when the old equipment is changed to the new lubricating oils, it should be tested before it can be formally used; When replacing the new grease, the waste lubricating grease should be removed first and the parts should be cleaned. When adding lubricating oil, the waste lubricating oil should be extruded until the new lubricating oil is seen at the drain port.

(4 ) attaches great importance to the process of filling lubricating grease management

Before receiving and filling lubricating grease, strict attention should be paid to the cleaning of containers and tools, and the grease supply port on the equipment should be wiped clean in advance to prevent the mixing of mechanical impurities, dust and sand.

( 5 ) notice season with fat timely replace

If the temperature difference between winter and summer in the environment of the equipment is large, if the winter fat is used in summer or vice versa, the result will be counterproductive.

(6 ) pay attention to regularly add in lubricating grease

If the above 6 points are done, the bearings of the screw air compressor can ensure normal operation.
