Therefore, the wholesale manufacturers of hydraulic elevators remind that there are three main ways to adjust the speed control circuit: throttling speed control circuit: quantitative pump oil supply,Sesena Hydraulic automatic lifting platform, using flow valves to adjust the flow in and out of the actuator to achieve speed control; In the volume throttling speed control circuit, the oil is supplied by the pressure limiting variable pump, and the flow rate into the actuator is adjusted by the flow valve to adapt the flow rate of the variable pump to the regulated flow rate of the speed control valve.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.Sesena ,The above are common situations, 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.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,If the circuit of the device is not disconnected or lowered, it is necessary to check the fuse for repair and replacement.Lifting 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.Each brush should be kept clean on its surface, and the brush pressure should be adjusted to ensure that its area is not less than %.

When installing, disassembling, and adjusting the rotating mechanism, attention should be paid to ensuring that the middle line is parallel to the middle line of the gear, and its meshing surface is not less than %. The meshing clearance should be suitable for the brakes of each mechanism. The clearance between the brake wheels should be regularly checked and adjusted to ensure its flexibility and reliability. There must be no dirt on the friction surface and it must be cleaned with gasoline or diluent.What are the requirements for the pit? This type of cargo elevator only needs - centimeters and does not require too much space. The installation of scissor type hydraulic cargo elevators is different from that of guide rail type hydraulic cargo elevators. The scissor lift cargo elevator has a large load-bearing capacity, and the pit depth needs to be set at around - centimeters. It can also be designed according to customer on-site needs.The electromagnetic coil of the electromagnetic directional valve is not firmly fixed, and frequent separation and suction can also produce high noise.Excellent service,When the hydraulic system malfunctions, the hydraulic elevator may experience problems with the hydraulic pump, motor, valve and hydraulic installation after repairing the hydraulic system, which can easily cause vibration and generate significant noise.Pre install equipment, maintain unobstructed access roads and sufficient parking space before pre installation. Some hydraulic cargo elevators require heavy lifting assistance for installation, some require equipment such as forklifts for installation, and some can be pre installed manually. When it is necessary to install with the assistance of a truck crane and a forklift, full consideration should be given to whether the on-site environment meets the working conditions of the truck crane.Therefore, the wholesale manufacturers of hydraulic elevators remind that there are three main ways to adjust the speed control circuit: throttling speed control circuit: quantitative pump oil supply, using flow valves to adjust the flow in and out of the actuator to achieve speed control; In the volume throttling speed control circuit, the oil is supplied by the pressure limiting variable pump, and the flow rate into the actuator is adjusted by the flow valve to adapt the flow rate of the variable pump to the regulated flow rate of the speed control valve.

When the hydraulic lifting platform is working, the larger the mass of the object, the greater the shakingProcess inspection,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,Sesena Mobile hydraulic lifting table supply, 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.When working on the dam crest, steep slopes, roofs, cliffs,Sesena Guide rail hydraulic lifting platform, towers, suspension bridges, and other dangerous edges, safety nets or protective railings should be installed on the side facing the air. Otherwise workers must use safety belts. Ice, snow, gravel, and soil on the steep slopes of steep cliffs, boarding bridges, or sidewalks must be regularly cleaned, and a -meter high railing must be installed on the outer side. Install an centimeter high side board or soil ridge on the inner side of the railing to prevent falling objects from injuring people.The contact of the travel switch must be firmly opened and closed,Each brush should be kept clean on its surface, automatic lifting platforms, hydraulic lifting platforms, folding arm lifting platforms, and sleeve type lifting platforms according to their different modes of movement.The installation personnel should have the qualification for installing hydraulic cargo elevators, carefully implement the special construction plan for installation and construction, and provide safety technical disclosure to the installation personnel for technical design.
