How to check the imported bearing lubricating grease is not moldy
1. Sunshine irradiation method
In the sunny life, use a screwdriver to remove the grease, and then fly to 45 degrees. Compared with the sun, observe the droplet condition, in the sunlight, you can clearly see no debris in the grease is **, you can play the effect again, debris is too much, you must replace the grease.
2. Droplet imprint method
Take a clean white filter paper, a few drops of oil leakage on the filter paper, grease leakage, if there is black powder on the surface, there is a sense of resistance in contact with the hand, indicating that there are more residues in the grease, grease is not powdery, dry and clean, and the imprint is light yellow.
3. Observation of oil row
Take two beakers, one full of grease to be checked, an empty on the table. Remove the beaker with oil from the desktop by 30 to 40 centimeters and tilt it to allow the grease to flow into the empty cup and observe its fluidity. High performance to price ratio grease should be long, thin, uniform and continuous. If the grease discharges quickly and slowly, the grease is said to be moldy.
