Gear pump use matters needing attention

Gear pump precautions: 1, timely oil change. Should be designated oil change indicator for new oil, no oil analysis means, according to the regulations by the oil change period.Motor factory recommended oil change period of 30000-48000km. Oil change, should be hot while the release of used oil , And clean the gear and gear box before adding new oil. Refueling, should prevent water and impurities mixed. 2, the amount of fuel should be appropriate. The amount of oil should be appropriate, can not be too much or too small. Too much will not only increase the oil mixing resistance and fuel consumption, but also may be gear oil through the rear axle shell into the brake drum (if the bad seal) caused by brake failure; So that poor lubrication, temperature transition is too high, accelerated gear wear, gear maintenance will be adversely affected gear oil surface should generally be added to the lower edge of gear box flush with flush, and should always check whether the gear tank leakage, and Maintain the oil seal, cushion intact. 3, fair use gear pump is conducive to gear maintenance. Gear oil has a long service life, such as the use of single-stage oil, the use of different viscosities for the maintenance of the season change label.If the old oil released less than the oil change deadline, you can add the car when the oil change again. Storage, beware of moisture, mechanical impurities and waste oil pollution 4, do not muddy oil and gear oil SAE classification label. In the calculation of scale to avoid muddy mud, marked as high classification mark used in the gear oil, low grade mark for the engine lubricating oil, but for the old grade gear oil classification number is lower, attention should be paid to the gear pump and the engine There is no contact with the oil viscosity level, the model can not be interoperable with each other. Do not use the gear oil as the engine oil, otherwise the engine will be fired, sticky cylinder and sintered piston top and other serious accidents. 5, do not mistakenly believe that high-viscosity gear oil lubrication performance is good. The use of too high viscosity gear oil, will significantly increase fuel consumption, is not conducive to the repair and maintenance of the gear conservation, especially for high-speed cars more influential, as far as possible the appropriate multi-stage gear oil. 6, can not use ordinary gear pump instead of hypoid gear oil Why say so? Due to the very large sliding between hypoid gear pump teeth, ordinary gear pump can not maintain sufficient lubricating film, if used in the meantime of ordinary gear oil, hypoid gear will soon be damaged. How to distinguish between the use of ordinary gear oil and quasi Hyperboloid gear oil? A: Fractional hypoid gear oil colors are generally yellow-green to dark green and dark brown red, etc., other gear oil colors are generally dark black, pay attention to when using the distinction is not to abuse hypoid gear oil to replace Ordinary gear oil, otherwise, will cause transmission gear wear and tear of the unnecessary economic losses must be based on the characteristics of the gear drive, use the right gear oil performance 7, the gear pump taboo, from the gear pump repair and maintenance In use, it is strictly prohibited to add diesel oil to the gear oil for dilution, nor because of the impact of the winter start to bake the rear axle, transmission, to avoid severe deterioration of gear oil.If this situation should be replaced by low viscosity Multi-stage gear oil.
