HowardLifting platform hydraulic pressurerelated information

After hours of elevator operation, carry out medium maintenance on the mechanical and electrical systems.The lifting platform is placed on a horizontal support surface, and the concentrated load of MAX load capacity is placed at any position mm away from the periphery of the workbench. After lifting times, each load-bearing component must not have deformation or cracks.Howard,Today, we will share with you why hydraulic cargo elevators are ideal equipment for transporting goods?Check valve leakage: If the natural wear of the check valve exceeds the specified value after long-term use, it will cause leakage. Disassemble and clean the check valve, and replace it if necessary.Kiffa,Reason: The lowering speed valve is out of adjustment. Cleaning method: If the lowering speed valve is adjusted, and if the adjustment is ineffective,HowardMechanical hydraulic lifting platform, replace it with a new valve.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, 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, causing air to vibrate inside the pilot valve and generate noise. So we need to regularly clean the overflow valve. When the overflow valve is damaged or severely worn, it should be replaced.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)

The downward movement of the hydraulic cylinder (i.e. lowering of heavy objects). The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic directional valve, and the return oil from the lower end of the hydraulic cylinder returns to the oil tank through the balance valve hydraulic control one-way valve, throttle valve, and explosion-proof electromagnetic directional valve. To ensure a smooth descent of heavy objects and safe and reliable braking, a balance valve is installed on the return oil circuit to balance the circuit and maintain pressure, so that the descent speed does not change due to heavy objects. The throttle valve regulates the flow rate and the ascending and descending speed. To ensure safe and reliable braking and prevent accidents, a hydraulic control one-way valve, also known as a hydraulic lock, is added to ensure safe self-locking in the event of an accidental rupture of the hydraulic pipeline. An overload sound control alarm has been installed to distinguish between overload or equipment failure.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.Remove the hydraulic oil tank filler cap, filter cover,HowardHydraulic lifting platform fixed type, inspection hole, hydraulic oil pipe and other parts to avoid dust when removing the system oil pipe. Clean the disassembled parts before opening them. When disassembling the hydraulic oil tank filler cap, first remove the soil around the tank cap, loosen the tank cap, and remove any remaining debris from the joint (do not rinse with water to prevent water from seeping into the tank). After confirming cleaning, open the tank cap.original,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, 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.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.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.

Stable and widely applicable cargo lifting equipment is mainly used for transporting goods between height differences in production lines; Material online and offline; Adjust the height of the workpiece during assembly; High altitude feeder feeding; Lifting of components during assembly of large equipment; Large machine material and cutting; The warehouse loading and unloading site is equipped with forklift and other transportation vehicles for rapid loading and unloading of goods.Good quality,The above are the working principles of three common elevators, and there are also some forms of elevators that are not common,HowardHousehold elevator, such as cylinder mounted elevators, curved arm elevators, car mounted elevators, because the stability of the hydraulic system can bring better user experience and safer operation to the equipment, which has been favored by many users.When working at heights, except for relevant personnel, no one is allowed to walk or stay below the workplace. Fencing or other protective devices should be installed below the workplace to prevent falling objects from injuring people.The above are the working principles of three common elevators, and there are also some forms of elevators that are not common, such as cylinder mounted elevators, curved arm elevators, car mounted elevators, because the stability of the hydraulic system can bring better user experience and safer operation to the equipment, which has been favored by many users.HowardThe contact of the travel switch must be firmly opened and closed, and the contact crater should be polished in a timely manner.Surface paint quality: The paint should be smooth and flat, have good adhesion with metal, have uniform color, no bubbles, no cracks, and there should be no wrinkles, pits, paint leakage, and sagging.Reason: The lowering valve is not tightly closed. Cleaning method: Check if the lowering valve is powered on. If there is no power supply, clear the malfunction of the lowering valve itself or replace the lowering valve. It is necessary to keep the valve of the lowering valve clean and flexible.
