How to check whether imported bearing grease is mildew
1. Solar irradiation
In sunny life, use a screwdriver to remove grease and then fly to 45 degrees. Compared with the sun, observe the droplet condition, in the sun, it can be clearly seen that no debris in the grease is excellent, can play the effect again, when the debris is too much, the grease must be replaced.
2. Drop printing method
Take a clean white filter paper, a few drops of oil leak on the filter paper, after oil leakage, if there is black powder on the surface, it is resistant to contact with the hand, indicating that there is much residue in the oil, the oil is not powdery, dry and clean, and the imprint is light yellow.
3. Oil discharge observation
Take two beakers, one full of grease and one empty on the table. Remove the beaker containing the oil from the table by 30 to 40 cm and tilt it to allow the grease to flow into the empty cup and observe its flow. The high performance price is longer, thinner, uniform and continuous than the grease. The fat is fast and the fat is slow, which means the fat is moldy.
4. Hand twist method
Twist grease between thumb and ring finger and grind continuously. Grease feel good, good wettability, less wear debris, no friction. If you feel that there is a lot of friction in the middle of your fingers like sand grains, it means that there is a lot of residue in the oil and it cannot be reused. Replace with new grease.
