with an allowable fluctuation range of± %.Separate: Loading and unloading on different platforms.Abundant,The manufacturer of hydraulic cargo elevators tells you the reason for the instability of hydraulic lifting equipment. Hangzhou hydraulic cargo elevator equipment has always had good stability, mainly used for heavy types of goods. However, during use, Hangzhou hydraulic cargo elevators may inevitably encounter some faults during the lifting process, such as very unstable conditions. What is the reason for the instability of the elevator? How to solve these problems?When the hydraulic system malfunctions, the hydraulic elevator may experience problems with the hydraulic pump, motor, and hydraulic installation after repairing the hydraulic system, which can easily cause vibration and generate significant noise.Mechanics,This paper briefly introduces some matters needing attention in the selection of oil tank for hydraulic elevators. The main functions of the hydraulic oil tank for elevators in the hydraulic system of elevators and hydraulic elevators and other hydraulic machinery are oil storage, heat dissipation, separation of air contained in oil and elimination of foam.There are many reasons for unstable workbench descent, such as overload, unstable support, severe eccentric load,AbundantLifting platform hydraulic pressure, hydraulic oil impurities, etc. In response to the above reasons, it can be solved by reducing the load adjusting the center of gravity of the load, and replacing hydraulic oil wholesale for hydraulic cargo elevators.The vibration range is proportional to the lifting height. The higher the height, the larger the shaking range, especially for mobile hydraulic cargo elevators. When the working height exceeds meters, the wind ropes at the four corners of the hydraulic cargo elevator should be tightened to strengthen leg protection, increase stability, and reduce shaking.

After the pre installation is completed, the pre installed equipment should be fixed, and the positions of cables, oil pipes, and components such as the pre installed frame should be confirmed to be correct before reinforcement work can be carried out. Reinforcement requires welding or screws, and the hydraulic cargo elevator after reinforcement has robustness and safety.Hydraulic elevators have two working periods and two end dwell times within a working cycle. Working hours refer to the period of lifting and falling objects. The suspension period refers to the period during which the machine temporarily stops working at the required height of rest. Therefore each working period is divided into three different stages: starting,Abundant10 meter lifting hydraulic platform, constant speed lifting and braking.The speed circuit is the circuit that switches the motion speed and speed of the actuator in the hydraulic system of the guide rail hydraulic lifting platform. Mainly including valves, pumps, and actuators. The commonly used speed circuits include speed circuits, high-speed circuits, and speed switching circuits.Analysis project,The noise and oil level of the elevator oil cylinder are too low. From the air at the connection of the oil filter or joint to the oil, the coupling inside the oil cylinder is loose. The internal fault of the oil cylinder is that the installation of the oil cylinder motor is not concentric. From the motor, the air and oil at the moving shaft are blocked. The oil return pipe of the oil filter is loose, and the air or oil pipe is on the oil surface, Mixing air into the oil to eliminate: The concentricity should be adjusted to within .MM. The coupling should be repaired or the oil pump should be replaced to increase the oil volume above mm in the oil filter and joint positions. The rotating shaft sealing ring should be replaced to clean the oil filter screen, filter the oil, lock the return oil pipeline, and extend the return oil pipeline below the oil level. If there is air mixed in the oil or the air in the hydraulic cylinder is not completely discharged, it will cause cavitation under high pressure and cause significant noise. At this point, it is necessary to exhaust the air in a timely manner.Load bearing capacity: The lifting platform is placed on a horizontal support surface, and the workbench is evenly loaded to % of the maximum load capacity. After lifting times, each load-bearing component must not have deformation or cracks.The classification of lifting platforms is as follows: they are divided into mobile lifting platforms, automatic lifting platforms, hydraulic lifting platforms, folding arm lifting platforms, and sleeve type lifting platforms according to their different modes of movement.

For hydraulic cylinders in hydraulic elevators, it is not practical to change their effective working area A (equivalent to displacement) to adjust the speed. Generally, speed regulation can change both the flow rate and the motor displacement.Total quality assurance,Regularly check all wires and cables for damage. It is necessary to wrap and replace the damaged parts in a timely manner.How to maintain the cleanliness of hydraulic elevators. If more high-quality hydraulic oil is added, these additives will lose their effectiveness after a period of time.After long-term use of the automatic lifting platform equipment, it is inevitable that some malfunctions will occur. In order not to affect work, it is necessary to promptly solve the difficulties in starting the motor and abnormal sounds. Generally, due to overload insufficient power supply, and a small cross-sectional area of the power supply cable, the starting voltage drop is too large and the price of the cargo elevator is reduced.Abundant,The hydraulic pump produces noise. When the hydraulic elevator rises, the hydraulic pump runs at high speed. If there is a problem with the gears or bearings of the hydraulic pump,AbundantHydraulic lifting platform, which causes periodic changes in the hydraulic system pressure, it will also cause resonance in the hydraulic system and generate noise.I believe many people want to know about the maintenance issues of guide rail hydraulic lifting platforms, as it is related to their service life. During use, frequently check the connection of each part. If loose, tighten it. When the body is under pressure, the tightness of the connecting bolts of the body should be checked (the pressure state that can be used). All connecting shafts should have split pins and hydraulic cargo elevators should be fully opened.The hydraulic lifting platform often checks the connection status of each part, and if there is any looseness, it should be tightened. The connection bolts of the machine body should be checked for tightness when the elevator body is under pressure (the compression condition can be formed by rotating the arm). All connecting shafts need to have split pins and need to be fully opened.
