Wu QiangManufaRemember not to overload, overload is the root cause of many faults.
The manufacturer of the hydraulic cargo elevator tells you the reason and cleaning method: Reason: Overload cleaning method: Reduce the load to clean. Reason: The return valve is not closed. Cleaning method: Tighten the return valve to clean. Reason: The one-way valve of the manual pump is stuck and the return valve is malfunctioning. Cleaning method: Unscrew the bolt at the valve port of the oil pump, conduct maintenance, cleaning, and replace the cleaning hydraulic oil to clean.
Wu Qiang.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.
Do not use hydraulic lifting equipment with malfunctioning issues. The problem should be resolved before carrying cargo.
.The use of cleaning oil and the brand used in the system
Each box distribution box, it is easy for hydraulic cargo elevator manufacturers to cause this problem.
Regularly inspect the hydraulic lifting equipment of the upper and lower materials to ensure the safety of the rail type elevator and the safety of the material supply to the rail type lifting platform.
The size of the oil cylinder should be minimized as much as possible while meeting the design requirements. The smaller the diameter of the oil cylinder, the faster the lifting speed.
Reason: 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.
Installation material list.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 shaking
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,Wu QiangHydraulic lifting table, 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.
Regularly check the operation of each mechanism for normal operation and noise. If any faults are found, the hydraulic cargo elevator wholesale should be promptly eliminated. Otherwise, it will affect the use of the guide rail hydraulic lifting platform. When refueling the hydraulic oil should be filtered and filled,Wu Qiang3 ton hydraulic lifting platform, and the refueling tools should be reliable and clean. The hydraulic cargo elevator manufacturer should not remove the filter at the fuel tank filler to improve the refueling speed. Refueling personnel should use clean gloves and work clothes to prevent solid and fiber impurities from falling into the oil.
For hydraulic cylinders in hydraulic elevators, it is not practical to change their effective working area A (equivalent to displacement) to adjust the speed. Generally, the speed can only be adjusted by changing the flow rate. For variable displacement motors, speed regulation can change both the flow rate and the motor displacement.
original.The use of cleaning oil and the brand used in the system
Therefore, the oil should be replaced regularly to ensure that the additives are effective. The filter can only absorb a limited amount of dirt particles and other impurities from the oil. Replace the filter according to the recommended cycle to keep the system clean.
Set up warning lights around the guide rail type hydraulic cargo elevator equipment, and the warning lights will light up to warn operators when loading and unloading materials. Idle personnel are prohibited from entering the operating range.
Wu Qiang.When the hydraulic system malfunctions, motor, valve, and hydraulic installation after repairing the hydraulic system, which can easily cause vibration and generate significant noise.
The above are the working principles of three common elevators, and there are also some forms of elevators that are not common,Wu QiangSmall hydraulic lifting and leveling, 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.
The main device does not engage. When this fault occurs, check whether the three-phase power supply is normal, whether the internal and external emergency stop button switches, the electric lock switch are turned on, whether the three-phase electrical phase sequence is correct, and whether the relay working indicator light is on.
