A hydraulic elevator is a type of elevator equipment consisting of a walking mechanism, hydraulic mechanism, electric mechanism, and support mechanism. The hydraulic oil forms a certain pressure by the vane pump, and enters the lower end of the hydraulic cylinder through an oil filter, explosion-proof electromagnetic directional valve, throttle valve, hydraulic control one-way valve and balance valve, causing the hydraulic cylinder to move upwards and lift heavy objects. The return oil at the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof electromagnetic directional valve,Oil cylinder leaks. Long term use causes wear on the sealing ring in the oil cylinder and excessive oil leakage in the cylinder wall gap, resulting in the natural descent of the hydraulic cargo elevator. The sealing components need to be replaced immediately.Protective device: In case of power or oil circuit failure, there should be a safety rope to prevent the workbench from falling out of control. (Allow controlled descent)Soavinandriana,What are the methods for reducing shaking on lifting platforms? Reducing the shaking of the lifting platform can reduce the psychological obstacles of the operators, ensure the smooth progress of the operation, and also greatly help improve safety. Warm reminder: safety, do not operate blindly. Lifts are widely used in many places,YaoduHydraulic guide rail type lifting platform, and their working principles vary. Today, we will analyze the working principles of elevators. The types of elevators are generally divided into the following: fixed elevators,YaoduHydraulic lifting platform and hydraulic lifting platform, This type of elevator uses hydraulic oil cylinders and pump stations to transmit power,YaoduHydraulic lifting platform 18 meters, in the form of a scissor fork type. According to customer requirements, the length of the support rod for the scissor fork, the number of layers, the angle of the angle axis, and the expansion and contraction of the oil cylinder complete the lifting operation. Its advantages are large load-bearing capacity, stable lifting, and high safety.Voltage too low: Measure the starter voltage, with an allowable fluctuation range of± %.Motor not running: Check all components of the motor for damage and check if there are any problems with the circuit and wiring.

Users should arrange dedicated personnel to operate hydraulic elevators, formulate usage details and safety precautions for hydraulic elevators based on their own situation, and hang them on theOil pipe leaks oil. Poor sealing of oil pipes, oil leakage, resulting in a decrease in pressure and a natural descent of hydraulic cargo elevators. It is recommended to carefully check whether the oil pipes are intact and undamaged.When disassembling and adjusting the reverse organization of the equipment, attention should be paid to ensuring that the centerline of the reverse organization reducer is parallel to the centerline of the gear, and its meshing surface is not less than %. The meshing gap should be appropriate.Quality risk,Reason: Manual pump and gear pump have severe oil leakage. Cleaning method: Replace the oil pump sealing ring to clean it. Reason: Gear pump is damaged, The oil pumped out has no pressure. Cleaning method: Replace the gear pump to clean the problem. Reason: Lack of hydraulic oil. Cleaning method: Add enough hydraulic oil to clean the problem. Reason: Circuit open. Cleaning method: Check the button and fuse to clean the problem. Reason: Filter blockage. Cleaning method: Replace or clean the problem. Reason: Support valve or electromagnetic directional valve malfunction. There are two situations: the input voltage of the electromagnetic coil is lack of V. The solenoid coil is burnt out and the valve core is stuck. Cleaning method: maintenance or replacement can be used to clean the natural descent of the lifting platform. Reason and cleaning method: one-way valve leakage cleaning method: check the check valve in the valve. Assuming there is dirt on the sealing surface of the check valve. Clean the check valve.The manufacturer of the hydraulic cargo elevator tells you the reason and cleaning method: Reason: Overload cleaning method: Reduce the load to clean. Reason: The return valve is not closed. Cleaning method: Tighten the return valve to clean. Reason: The one-way valve of the manual pump is stuck and the return valve is malfunctioning. Cleaning method: Unscrew the bolt at the valve port of the oil pump, conduct maintenance, cleaning, and replace the cleaning hydraulic oil to clean.New reference wiring diagram . Elevator leg noise. Mobile elevators should open the legs before operation. In this case, if the legs lack butter, noise will be generated.

The hydraulic elevator overflow valve can also generate high noise. When air is mixed in hydraulic oil, the overflow valve is stuck or severely worn, the spring of the overflow valve is fatigued and deformed, resulting in unstable pressure regulation of the overflow valve, and the relief time of the overflow valve is too short, it is easy to cause the pilot valve performance of the overflow valve to be partially stable, it should be replaced.Packaging strategy,A hydraulic elevator is a type of elevator equipment consisting of a walking mechanism, hydraulic mechanism, electric mechanism, and support mechanism. The hydraulic oil forms a certain pressure by the vane pump, and enters the lower end of the hydraulic cylinder through an oil filter, explosion-proof electromagnetic directional valve, throttle valve, hydraulic control one-way valve, and its rated pressure overflow valve is adjusted. The pressure gauge observes the reading value on the pressure gauge.The above are common situations causing the hydraulic cylinder to move upwards and lift heavy objects. The return oil at the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof electromagnetic directional valve, and there are many other reasons based on the actual situation. Hydraulic lift cargo elevators can have different configurations according to the installation environment and usage requirements of the factory building.When the hydraulic system malfunctions, the hydraulic elevator may experience problems with the hydraulic pump motor, and hydraulic installation after repairing the hydraulic system,The use of cleaning oil and the brand used in the systemLifting mechanism: The workbench should be ensured to rise and fall smoothly, and there should be no jumping lifting phenomenon. All moving parts should be flexible when moving, and there should be no jamming devices. The lifting system of the elevator is divided into electric or manual hydraulic systems, and there should be no leakage at all components, pipelines, and joints.There is noise inside the hydraulic cylinder. When replacing the hydraulic oil, there was air in the hydraulic cylinder due to an operational error. Under high pressure, it is easy to generate cavitation and high-frequency noise. When the rod is bent or replaced with a new seal, the new seal is too tight, which can also produce significant noise. If it is a problem of tight sealing, the noise can be reduced after running in for a period of time. If the rod is bent, it needs to be corrected. In addition, hydraulic pipelines should use hoses as much as possible, even when arranging pipelines, it can reduce vibration and noise and the pipelines should avoid dead bends as much as possible.
