It is a common problem that the working speed of small loader is too high. When jumping out of this problem, the work is weak, although it does not rotate; The working speed of the small loader is too high, which slows down the anodic oxidation of the shock absorber oil, resulting in the loss of corrosion resistance, which may lead to the damage of the rubber seal, resulting in a very large loss, although it should be the normal operation of the wire machine. The reason is that when the working speed of the small loader is too high, we should carefully and responsibly explain the problems and remove the problems on schedule. At present, the rotating speed continues to increase, the viscosity of shock absorber oil 107 silicone rubber of small loader continues to be affected, the chlorine leakage rapidly drops to the bottom, and the fog water at each wet acupoint is destroyed, so that the friction damaged parts of structural parts are fed quickly, and finally the speed rises slowly. When the rotating speed of the small loader is too high, the gap between the power transmission pairs caused by the data with different linear expansion coefficient will change abnormally. If the gap becomes larger, the oil chlorine leakage of the shock absorber will be serious. If the gap decreases, the components may get stuck with each other. The system water pressure is not adjusted properly. The speed regulating valve is the nerve center of the hydraulic transmission system, It controls the water pressure of the working oil entering the system. If the friction damaged parts of the angle valve of the speed regulating valve of the small loader have pressure relief or the pressure valve of the hydraulic torque converter is not flexible and stuck, which can not play a buffer role, it is because the oil pipeline of the hydraulic torque converter is not enough and the water pressure is reduced. When the chlorine leakage of the speed regulating valve is light, the chlorine leakage can be filled by increasing the system water pressure; If the friction parts of the angle valve are seriously damaged, the speed regulating valve or angle valve shall be replaced to improve the system water pressure.
