How to maintain the pump SKF bearing

(1) The pump that is newly put into use must be replaced with grease (oil) after 100 hours of operation, and then replaced once every 500 hours.
(2) Flow-resistant SKF bearings lubricated with grease. After 1500 hours of operation, the grease should be replaced. The amount of oil to be filled should not be too much or too little, because too much or too little grease will cause the SKF bearing to heat up. Generally, it is suitable to be 1/2 to 2/3 of the volume of the SKF bearing chamber.
(3) For SKF bearings lubricated with lubricating oil, the amount of oil should be added to the specified position.
(4) The container containing lubricating oil or grease should be clean and should be sealed normally. There should be no dust or iron filings to avoid damage to SKF bearings.
(5) Motor SKF bearings generally use sodium-based grease, which is characterized by high temperature resistance (125 ° C), but is easy to dissolve in water, so it can not be used for lubrication of water pump SKF bearings.
The maintenance and maintenance of SKF bearings is very important. It is related to its service life, work efficiency, know how to maintain the SKF bearings used by them. It benefits a lot. From the work aspect, it brings you high productivity and production. For quality products, economically, several maintenance can extend your life and save you money on re-purchasing.

Test the deterioration of TIMKEN bearing grease

Grease is critical in the use of TIMKEN bearings. If a deteriorated grease is used, it will not only function as it should, but it will also damage the TIMKEN bearing.
1 Oil flow observation method
Take two measuring cups, one of which is filled with the lubricating oil to be inspected, the other is placed on the table, and the measuring cup filled with lubricating oil is lifted off the table 30-40 cm and tilted to allow the lubricating oil to slowly flow to the empty cup. In the middle, observe the flow, the quality of the lubricating oil flow should be slender, even, continuous, if the oil flow suddenly and slowly, and sometimes there is a large flow, then the lubricant has deteriorated.
2 manual method
The lubricant is rubbed repeatedly between the thumb and the index finger. The better lubricant feels lubricated, less wear debris, and no friction. If you feel a large friction between the fingers, it means lubricating oil. There are many impurities inside, can not be reused, should be replaced with new lubricants.
3 lighting method
On a clear day, use a screwdriver to pry the lubricant at a 45-degree angle to the horizontal. Observe the sunlight and observe the oil droplets. Under the light, it can be clearly seen that there is no wear debris in the lubricating oil, which can continue to work. If the grinding debris is too much, the lubricating oil should be replaced.
4 oil drop trace method
Take a clean white filter paper, drop a few drops of oil on the filter paper. After the oil leaks, if there is black powder on the surface, touch the hand with a feeling of resistance, it means that there are many impurities in the lubricant, good lubricant No powder, it is dry and smooth by hand, and it has yellow marks.
