XinzhouHydraul
XinzhouProvincThe reason for the natural descent of the hydraulic boarding bridge lifting platform is that the one-way valve is leaking, the lowering valve is not tightly sealed, and the oil cylinder is leaking. Solution: Check the one-way valve in the valve group. If dirt is found on the sealing surface of a single valve, clean the one-way valve. Check if the lowering valve has power. If there is power, troubleshoot the lowering valve itself or replace the lowering valve. The slide valve of the lowering valve must be kept clean and move flexibly.
As we all know
Xinzhou.B) When maintaining the hydraulic system only clean plastic plugs can be used to seal the ends of the pipeline.
The safety valve of the mobile hydraulic boarding bridge can also generate high noise. When air is mixed into hydraulic oil, the relief valve gets stuck or severely worn, and the fatigue deformation of the relief valve spring leads to unstable pressure regulation of the relief valve. The pressure release time of the relief valve is too short, which can easily lead to local stability of the pilot valve performance of the relief valve. Noise is generated by the vibration of the pilot valve's air. Therefore, we should regularly clean the safety valve, and replace it if it is damaged or severely worn.
.It is strictly prohibited to apply excessive pile loads around the foundation pit.
When working in foundation pits or depths, a helmet must be worn.
There are three movable boards on both sides of the air conditioning board, which can effectively prevent the adjustment board from falling down and keep the pressure foot in a safe state.
Reason for the lifting table not lowering: The lowering valve is malfunctioning, and the lowering speed valve is out of adjustment. Solution: When pressing the lowering button, check if the lowering valve is energized. If there is no electricity, try to eliminate it; If there is electricity,XinzhouProvincial Mobile Boarding Bridge, troubleshoot the lowering valve itself or replace the lowering valve. The lowering valve should be kept clean.
Keep the hydraulic boarding bridge system clean: regularly replace the oil and filter. Good hydraulic oil contains various additives that can prevent oil deterioration or blockage of system components. However, these additives will lose their effectiveness after a period of time. Therefore, the oil should be replaced regularly to ensure that the additives are effective. The filter can only absorb a limited number of dirt particles and other impurities from the oil. Replace the filter according to the recommended cycle to keep the system clean.
Common&quo; Work” Steel structure planning can withstand uniform pressure, and be more robust than other channel structures.
Customer first.After the boarding bridge work is completed all parts should be scrubbed and cleaned. When not working, the workbench should be lowered to a low position.
Shake the handle to raise the boarding bridge to the height of the container.
The correct operation of the hydraulic boarding bridge is good maintenance, and how to operate it correctly. Let me briefly introduce the operating steps of the hydraulic boarding bridge, hoping to bring more help to everyone.
The pressure on the axle will reduce the service life of the boarding axle.
system.Operation degree: There are two types of operations that can be used to raise and lower the boarding bridge. One is a manual pump station, which uses manual hydraulic lifting, which is labor-intensive and somewhat labor-intensive. Advantages: It can be operated and used in any situation. Two types of electric pump stations use electric hydraulic lifting and lowering, which reduces labor intensity and saves labor. Disadvantage: Once the power is cut off, it will not be able to be used, but now there are both manual and electric boarding bridges that are more convenient to use.
Features: Generally, domestic brands are the main products, with a lightweight boom design, which has a wide range of operations,XinzhouMaintenance of boarding bridge, lightweight flexibility, and high work efficiency. Large leg span, good stability, automatic detection of leg reverse force, ensure that the platform car can be lowered and the rotating mechanism can be manually rotated. The cylinder rod is protected by a protective sheath, and the arm head is equipped with a dustproof device.
During the application process of hydraulic boarding bridges it is necessary to follow the operating procedures to ensure the normal operation of the equipment. What precautions should we take when using hydraulic boarding bridges?
Xinzhou.Install drainage ditches on the ground near the pit of the simple boarding bridge,XinzhouMobile Yard Ramps , and take corresponding drainage measures for the top, surface, and foot of the slope, especially for the simple boarding bridge.
Reason for the lifting table not lowering: The lowering valve is malfunctioning, and the lowering speed valve is out of adjustment. Solution: When pressing the lowering button, check if the lowering valve is energized. If there is no electricity, try to eliminate it; If there is electricity, collision of the support structure should be prevented, and changes in the soil wall should be paid attention to at all times. If any abnormal phenomena such as cracks are found, construction must be suspended and reported to the superior for handling.
