How to regenerate waste gear oil?
If the gear oil viscosity is large, hard to filter, add 40% light diesel oil in gear oil (range of 160300 degrees Celsius), can also be regenerated oil when distilled oil), stirring evenly, through steam coil heating the oil to 90 degrees Celsius, the precipitation of 2-1 day, middle oil removal. And then heated to 110 degrees Celsius, then filtered by a filter press. After filtration the semi-finished oil into a clean pot distillation, steam distillation, distillation to 300 degrees Celsius ceasefire, distilled diesel next time; the temperature dropped to 150 degrees Celsius after the release, the regeneration of gear oil.
The waste oil into the wok in gear, heated to 130160 degrees Celsius, then serve hot with frame filter filter, can be recycled. If there is no qualified product with wire net filter, filter 160 or 200 holes in the heating, into the conical bottom container, thermal static precipitation for more than 48 hours, let metal the particles in the oil deposited on the conical bottom, loose sediment, the regeneration oil.
Gear oil in an airtight working mechanism, its working temperature of 6580 degrees Celsius, not affected by high temperature oxidation occurs, will not be burning as gasoline and diesel dilution, metal particle friction between the gear only gradually deteriorate. Therefore, regeneration of waste gear oil, do not need to use sulfuric acid clay treatment, only need to use the method of heating or heating precipitation filtration, can restore the quality index, the operating procedures are as follows.
