Lift manufacturer: hydraulic lift problem analysis

Release time:

Oct 12,2022

   The elevator manufacturer stated that hydraulic elevators can generally rise normally during operation. If they cannot be adjusted halfway through the continuous rise process, the problem may be due to the damage of the starting capacitor. Therefore, it is necessary to check the power capacitor of the elevator in such a situation. The natural occurrence of such a situation may also be due to insufficient remaining oil in the hydraulic press oil tank. When the hydraulic elevator cannot be raised and only needs to be lowered, it is necessary to check whether the generation is firmly grasped, especially to see if there is a 5mm travel distance between the upper and lower parts. Generally, in such a situation, there will be a small screw on the back cover plate inside the Konka production, which can calibrate the internal spring. However, if the hydraulic elevator cannot rise to the set relative height, it is necessary to check the other oil tank. The main thing is to check whether the hydraulic pressure inside the oil tank has reached the standard volume, and together, check if there is any oil leakage in the oil tank.


   The elevator manufacturer stated that if the hydraulic elevator shakes or experiences vibration during adjustment or left-right operation, it is necessary to check whether there are particles on the sliding track of the elevator. Of course, this situation may also be caused by waste materials inside. Therefore, lubricating grease must be applied inside the sliding track. If not added in time, it will cause long-term damage or cause the hydraulic elevator to be stuck and damaged. It is not difficult to see that various small problems need to occur during the use of hydraulic elevators. When such problems occur, safety inspections should be carried out in a timely manner to ensure the smooth application of hydraulic elevators during use. When making choices, it is important to purchase them directly based on customer needs. This can be done by selecting suitable hydraulic elevators for different types of switching power supplies and explosion-proof equipment.


   Elevator manufacturer: What are the hazards of low temperature on hydraulic elevators?


   1. The impact of low temperature on building steel, the raw materials of key load-bearing components in low temperature environments must not only meet the strength requirements, but also meet the requirements of fracture toughness. The welding structure of ultra-low temperature load-bearing components has an impact on the internal stress, stress, etc. of electric welding. Therefore, suitable structural types should be selected for elevators in low-temperature environments.


   2. The impact of low temperature on the hydraulic oil, lubricating grease, and diesel engine of hydraulic elevators, as well as the lifting, rotating, and telescopic operations of the elevator support and lifting operation of the winch, are all driven by hydraulic oil as the medium. The viscosity of hydraulic oil is particularly important. If the viscosity is too high, the internal structural friction of the system will increase, the flow resistance will increase, the temperature will rise too quickly, and the posture will fall behind during operation; If the viscosity is too low, the volumetric efficiency of the pump will be low, and the wettability will be poor. The frictional resistance between components will increase, and the viscosity of hydraulic oil will change with the operating temperature. Therefore, when choosing ultra-low temperature hydraulic oil, attention should be paid.
