Information
The operation process of the bearing is generally inseparable from the lubrication of the lubricating oil, which can effectively reduce the friction coefficient and the increase in temperature between the bearings. If the lubricating oil is deteriorated, it is not good for the bearing, only the disadvantage. How can we determine whether the bearing lubricant has deteriorated?
Let’s take a look at how we can determine whether the grease has deteriorated:
1. Oil flow observation method
Take two measuring cups, one of which contains the lubricant to be inspected, and the other empty on the table. Lift the measuring cup filled with lubricant 30-40 cm away from the table and tilt it to let the lubricant slowly flow to the empty cup. Observe the flow condition. The flow of good quality lubricating oil should be slender, uniform, and continuous. If the oil flow is fast and slow, and sometimes a large piece of oil flows down, it is said that the lubricating oil has deteriorated.
2. Hand twist method
Twist the lubricating oil between the thumb and index finger and repeatedly grind. The better lubricating hand feels lubricity, less abrasive debris, and no friction. If you feel a large friction like sand between the fingers, it indicates that the lubricating oil There are many impurities in it and it can't be used any more, so it should be replaced with new lubricant.
3. Illumination
On sunny days, use a screwdriver to lift up the lubricant at a 45-degree angle to the horizontal. Control the sunlight and observe the oil droplets. Under the light, it can be clearly seen that there is no wear debris in the lubricant. It can continue to function. If there is too much wear, the lubricant should be replaced.
4. Oil droplet trace method
Take a clean white filter test paper, drip a few drops of oil on the filter test paper, after the lubricant leaks, if there is black powder on the surface, if you touch it with your hands, it means that there are many impurities in the lubricant, good The lubricating oil is powder-free, dry and smooth to the touch, with yellow marks.
