Industrial lubricants include a very wide variety of lubricants and practical application areas. Although there are many varieties, the main ones are: steam turbine oil, bearing lubricating oil, hydraulic oil, Gear Oil, machine tool lubricating oil, lubricating grease, Metal Working Fluid, textile lubricating oil, quenching oil, heat transfer oil , electrical oil, refrigeration oil, anti-rust oil, etc., can be described as a large amount and a wide range of applications in the industry, and are generally familiar varieties.
Because of the large demand, storage is not easy. If it deteriorates, it cannot be used. So how can we distinguish whether industrial lubricants have deteriorated? The color of the deteriorated industrial lubricating oil will be dark black, with more foam and emulsification; we can also distinguish it by grinding with fingers, such as no stickiness, peculiar smell, more melanin or dark brown, which can prove the The oil has gone bad. If the deteriorated industrial lubricating oil is used, the parts will be damaged, the life of the machine will be affected, and there may be safety accidents in serious cases. So what methods can identify the deterioration of industrial lubricants? 1. Observation method By taking 2 measuring cups, one filled with lubricating oil and the other without lubricating oil, then raise the measuring cup with lubricating oil to the height of 3 cups, and pour it into the empty cup while tilting, and during the observation period, the lubricating oil is , Good quality industrial lubricating oil will flow into the empty cup evenly, slender and continuous.
2. Finger grinding method Grind the lubricating oil through the thumb and index finger of the fingers. After repeated grinding, the lubricating oil, the degree of friction and the amount of wear debris can be judged. A good lubricating oil will have good lubricity and very little wear debris. And there is no friction, but if there are particles when rubbing, it means that the oil has a problem and cannot be used, and it should be replaced in time.
3. Sunlight method You can stick the industrial lubricating oil on it with a screwdriver, and then tilt it at an angle of 40 degrees, let the oil slowly fall down the tip of the screwdriver in the sun, and observe the oil droplets. You can clearly see whether the oil is in the light. Wear debris, if there is no wear debris, it is proved to be good, if there is wear debris, and there are too many wear debris, it is recommended to replace it.
4. Filter paper trace method Prepare a clean white filter paper, drop a few drops of lubricating oil on the filter paper, wait for the lubricating oil to leak, and then observe whether there is black powder, and then touch it with your fingers to see if there is a sense of resistance. If there is, it means that there are many magazines. , need to be replaced; good lubricating oil should have no powder, and it is very smooth when touched by fingers, and the color is yellow, which means there is no problem with the lubricating oil.
