Stability: The workbench should evenly withstand % of the MAX load capacity and be stable at the MAX elevation.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, 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 its rated pressure overflow valve is adjusted. The pressure gauge observes the reading value on the pressure gauge.Dandong,Below, we will analyze for everyone. According to the market survey and understanding conducted by the editor of hydraulic freight elevator manufacturers, many customers choose hydraulic elevators instead of elevators due to the following reasons: narrow transportation location, which cannot meet the requirements of elevators; Unable to excavate the elevator shaft at the working location; Elevators are expensive and difficult to meet their needs.Do not use hydraulic lifting equipment with malfunctioning issues. The problem should be resolved before carrying cargo.Lido di RomaThere is a phenomenon of self stopping when running up and down. Due to poor contact of the safety protection switch, it is easy for hydraulic cargo elevator manufacturers to cause this problem.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.Oil leakage from the oil cylinder: If it is a problem with the sealing ring, replace the sealing ring. If there are debris or debris on the oil cylinder, it is recommended to replace it with a new one.

When the hydraulic oil of the equipment is insufficient, it will not cause lifting. At this point, you only need to add enough hydraulic oil to run.High altitude work should always use tool bags. Tools with larger boarding bridges should be tied to sturdy components with ropes, and should not be placed randomly to prevent accidents caused by falling from a height.After hours of elevator operation, perform minor repairs to the mechanical and electrical systems.Focus on Development,When placing materials on the platform, they should be placed in the middle of the platform as much as possible. The weight of the goods should be within the standard load range of the equipment, and the volume of the goods should not exceed the platform size of the equipment. Otherwise,DandongHydraulic guide rail type lifting platform, materials and lifting platforms may be injured and dangerous accidents may occur. High priced and various specifications of elevator manufacturers provide timely supply, with high cost-effectiveness, and have become the preferred brand for many wire products. Welcome to purchase! There is air in front of the pilot valve of the elevator overflow valve noise overflow valve. The damping hole on the main valve core of the overflow valve is blocked by oil dirt, and the pilot valve and valve seat are matched without spring deformation or incorrect installation. The remote control port has excessive oil flow, low or high hydraulic oil viscosity, and resonance occurs with components in the circuit. Troubleshooting: Strengthen sealing, repeatedly adjust the pressure, exhaust and clean the valve body several times, Make the damping hole unobstructed, reduce the flow of the remote control port replace the oil, and other components. The pressure setting of other components should not be similar to the pressure setting of the relief valve. . The noise of the elevator pipeline is usually caused by excessive dead bends or loose fixed sleeves in the hydraulic pipeline.

The smoothness of the gearbox, gearbox, external meshing gears, and hydraulic oil are all carried out according to the requirements in the smoothness table.consumption,Volume speed control circuit: Speed control is achieved by adjusting the displacement of a variable pump or variable motor.In addition, the lifting mechanism also needs to be equipped with powerful support frames. Therefore,DandongHydraulic lifting platform experiment, but should be based on the working conditions of the elevator.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.Dandong,When the hydraulic lifting platform is working, the load cannot exceed its rated load. When it is raised to a certain height, the larger the mass of the object, the greater the shakingReason: The lowering speed valve is out of adjustment. Cleaning method: If the lowering speed valve is adjusted, and if the adjustment is ineffective, replace it with a new valve.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.
