AnthonyHydraulThe cylinder head oil seal is too tight or the rod is bent, which can also cause noise during movement due to other forces. At this point, the oil seal or straightening rod must be replaced in a timely manner.
Pay attention to checking each steel wire rope for signs of broken wires and loose drums. If it exceeds the relevant rules, it is necessary to replace it immediately. The protection of steel wire ropes should strictly follow the rules of GB5144-85.
Anthony.When working simultaneously at the upper and lower levels, a tight and firm protective partition, canopy or other isolation facilities must be erected in the middle of the boarding bridge, and workers must wear safety helmets.
Therefore, 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.
.To consider its capacity,Anthony20 meter hydraulic lift, generally mobile equipment takes 2-3 times the high flow rate of pump Z, and fixed equipment takes 3-4 times.
Regularly check all wires and cables for damage. It is necessary to wrap and replace the damaged parts in a timely manner.
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.
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
Hydraulic cargo elevator: Only when the load of the hydraulic guide rail type lifting cargo elevator cannot start working, should the pressure of the hydraulic system be checked. If the pressure is below the normal range, the set value of the relief valve should be adjusted. Professional elevator manufacturers have high pressure resistance, good waterproof performance, fire and high temperature resistance, strong overload capacity, corrosion resistance, radiation resistance and long service life
Hydraulic lift cargo elevators belong to high-altitude work equipment. Small shaking of the scissor type structure is normal, but excessive deviation is a symptom. It is necessary to find the cause and make correct judgments in a timely manner. Generally speaking, operations above 8 meters are generally allowed. Due to its own weight devices above this height begin to vibrate in different ranges. The vibration range depends on factors such as weight,Anthonyfork lifter, lifting height, and intensity of high-altitude operations.
agent.Stability: The workbench should evenly withstand 125% of the MAX load capacity and be stable at the MAX elevation.
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 220V. 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 hydraulic cargo elevators reminds the use of guide rail hydraulic lifting cargo elevators. Guide rail hydraulic lifting cargo elevators: Do not stand within the specified range, draw on the guide rail lifting platform, prohibit any idle personnel from entering the work area, and maintain a clean and tidy workplace.
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.
Where can I find it?.The undercut length of the weld mm should not exceed 10% of the weld seam, and the depth should not exceed 0.4mm.
Hydraulic elevators and load-bearing oil cylinders can directly act on the foundation pit, requiring low shaft strength, and brick or brick concrete structure shafts.
There 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.
Anthony.Surface paint quality: The paint should be smooth and flat, have good adhesion with metal, have uniform color no bubbles, and there should be no wrinkles, pits, paint leakage, and sagging.
Hydraulic lifting table: the hydraulic lifting table is widely used in various industrial enterprises and production lines such as automobile, container, mold manufacturing,AnthonyElectric hydraulic lifting platform, wood processing, chemical filling, etc., to meet the lifting needs of different operation heights, and can be equipped with various table forms (such as ball, roller, rotary table, steering, tipping, telescoping), linkage, explosion-proof) it has stable and accurate lifting, frequent starting The characteristics of large load capacity effectively solve various lifting and lowering difficulties in industrial enterprises, making production operations smooth.
The vibration range is proportional to the lifting height. The higher the height, the larger the shaking range, especially for mobile hydraulic cargo elevators. When the working height exceeds 10 meters, the wind ropes at the four corners of the hydraulic cargo elevator should be tightened to strengthen leg protection, increase stability, and reduce shaking.
