DresdenHydraulic lifting table liftingHow to distinguish between good and bad quality

After 1500 hours of elevator operation, perform minor repairs to the mechanical and electrical systems.

After 1500 hours of elevator operation, perform minor repairs to the mechanical and electrical systems.

Dresden.Check valve leakage, oil pipe check valve leakage. The solution is to carefully check whether the one-way valve is functioning properly. If it is not normal, it is recommended to replace the one-way valve with a new one.

The elevator is evenly distributed at any position on the guide rail at 150% of the maximum load capacity, the air and oil at the moving shaft are blocked. The oil return pipe of the oil filter is loose 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, 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 0.1MM. The coupling should be repaired or the oil pump should be replaced to increase the oil volume above 400mm 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.

The development of elevators is at its peak, as many manufacturers have chosen more multi-story buildings to fully utilize the site, etc. should be kept clean and promptly cleaned of dust on electrical equipment.

Oil leakage is a common malfunction. Due to loose joints or damaged sealing rings,DresdenMechanical hydraulic lifting platform, oil leakage may occur. Therefore, this fault can be solved by tightening the oil leakage joint or replacing the damaged sealing ring.

It is not allowed to throw tools and materials up and down, and ropes should be used to tie or hang them to avoid injuring workers or scaffolding below.

The lifting platform is a multifunctional heavy loading and unloading mechanical equipment, which can be divided into fixed and mobile, guide rail and curved arm types. Fixed types include scissor elevators,DresdenAutomatic hydraulic lifting platform,DresdenImported hydraulic lifting platform, chain elevators, loading and unloading platforms, and attached electric construction platforms.

Process inspection.Oil leakage is a common malfunction. Due to loose joints or damaged sealing rings, oil leakage may occur. Therefore, this fault can be solved by tightening the oil leakage joint or replacing the damaged sealing ring.

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.

When using an electric mobile scissor lifting platform outdoors, if the wind force exceeds level 5, please stop using it; When the lifting height exceeds 10 meters, the wind ropes at the four corners of the hydraulic lift platform should be tightened and fixed and the support legs should be reinforced for protection and stability to avoid safety accidents caused by excessive swinging of the electric lifting platform

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 70%. 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.

Encyclopedic knowledge.Regularly check all wires and cables for damage. It is necessary to wrap and replace the damaged parts in a timely manner.

Cylinder diameter and hydraulic oil flow rate. The speed of the hydraulic lifting device is inversely proportional to the cross-sectional area of the cylinder rod and directly proportional to the flow rate of hydraulic oil. When the hydraulic elevator runs slowly, priority should be given to the hydraulic oil flow angle.

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 70%. 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.

Dresden.After 10000 hours of operation on the hydraulic lift, major repairs will be carried out to the mechanical and electrical systems.

The hydraulic oil used in the system has the same brand, and the oil temperature is between 45~80 ℃. Use a large flow rate to remove impurities from the system as much as possible. The hydraulic system needs to be cleaned repeatedly three times or more, and after each cleaning, the system should be drained while the oil is hot. After cleaning, clean the filter and add new oil after using a new filter element.

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.
