After the application of electric lifting platform, hydraulic goods elevator and slide rail type hydraulic lifting goods elevator for a period of time, due to the untimely maintenance, it is inevitable to have some small common faults, among which the electric lifting platform circuit system and hydraulic transmission system are the most common. Here, the hydraulic goods elevator Engineer will analyze the causes of the high temperature for you, hoping to help you:
1. Continuous overload application of electric lifting platform. 2. If the electric lifting platform works in the natural environment with too high temperature for too long, the temperature will rise rapidly; 3. If the nominal diameter of the oil pipe of the electric lifting platform is small or the sheet metal of the oil pipe is bent due to the external force, the nominal diameter of the fuel pipe will be reduced; the oil-water separator network of the oil inlet and the oil suction pipe will be damaged, resulting in the hydraulic oil mixed with solid particles and impurities blocking the oil path. The system pressure is greatly increased and the temperature of hydraulic oil is increased.
4. Due to the internal reason of the hydraulic cylinder of the electric lifting platform, after long-term application, the sealing damage of the damping framework inside the hydraulic cylinder is relatively serious, which leads to the expansion of the internal leakage of the hydraulic cylinder and the rise of the temperature.
5. If the maintenance of the motor with driving force is not carried out immediately, the rolling bearing will be damaged, the rotor of the motor will be swept, and the friction will cause heat generation
