There is noise inside the hydraulic cylinder. When replacing the hydraulic oil, there was air in the hydraulic cylinder due to an operational error. Under high pressure, it is easy to generate cavitation and high-frequency noise. When the rod is bent or replaced with a new seal, the new seal is too tight, which can also produce significant noise. If it is a problem of tight sealing, the noise can be reduced after running in for a period of time. If the rod is bent, hydraulic pipelines should use hoses as much as possible, even when arranging pipelines,BiawestockScissor fork hydraulic lifting table, it can reduce vibration and noise, and the pipelines should avoid dead bends as much as possible.The hydraulic oil used in the system has the same brand, and the oil temperature is between ~ ℃. 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.Biawestock,Hydraulic oil deteriorates or produces impurities. After long-term use of oil pressure, there may be impurities or deterioration in the oil. Sampling inspection should be carried out to see if there are solid particles, discoloration, and odor. If necessary the oil should be changed. There may be blockage in the hydraulic pipeline of the hydraulic cargo elevator. The hydraulic pipeline is also a very important part, and it is necessary to check whether the hydraulic pipeline is smooth. Focus on checking whether each type of hydraulic valve includes one-way globe valve, electromagnetic directional valve, proportional control valve, overflow valve, etc. If there are problems, the hydraulic valve should be cleaned or replaced in a timely manner.Each box distribution box, etc. should be kept clean and promptly cleaned of dust on electrical equipment.Aliyah,The characteristics of the platform include reliable hydraulic system, simple operation, large load-bearing capacity, and rear hinge support.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.Surface paint quality: The paint should be smooth and flat, have uniform color, no bubbles, no cracks, and there should be no wrinkles, pits, paint leakage, and sagging.

There are many reasons for unstable workbench descent, such as overload, unstable support, severe eccentric load, hydraulic oil impurities, etc. In response to the above reasons, it can be solved by reducing the load, adjusting the center of gravity of the load, and replacing hydraulic oil wholesale for hydraulic cargo elevators.Carefully prepare a special construction plan for installation and construction, and provide safety technical disclosure to installation personnel.Aluminum alloy elevators are different from other forms. This type of elevator is made of aluminum alloy material, which is lightweight and has a more beautiful appearance. The disadvantage is that it has a light load capacity and is only suitable for simple high-altitude maintenance work, and can only provide support for - people.Home page recommendation, as it is related to their service life. During use and frequent separation and suction can also produce high noise.I believe many people want to know about the maintenance issues of guide rail hydraulic lifting platforms, frequently check the connection of each part. If loose, tighten it. When the body is under pressure, 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.The elevator is evenly distributed at any position on the guide rail at % of the maximum load capacity, and should be stable at the maximum lifting height.

Oil leakage is a common malfunction. Due to loose joints or damaged sealing rings,BiawestockMast type aluminum alloy 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.Sincere service,Volume speed control circuit: Speed control is achieved by adjusting the displacement of a variable pump or variable motor.When working simultaneously at the upper and lower levels, canopy or other isolation facilities must be erected in the middle of the boarding bridge, and workers must wear safety helmets.Ensure that there is a suitable power supply at the installation site, and separate maintenance of the distribution box is required. The distribution box should have a leakage switch, and the hydraulic cargo elevator construction site should be equipped with a fire extinguisher to prevent welding operations from causing fires. When selecting a leakage switch, it should be suitable for the operating power.Biawestock,The lifting platform is a multifunctional heavy loading and unloading mechanical equipment,BiawestockDouble shear hydraulic lifting platform, guide rail and curved arm types. Fixed types include scissor elevators, chain elevators, loading and unloading platforms, and attached electric construction platforms.The hydraulic pump produces noise. When the hydraulic elevator rises, the hydraulic pump runs at high speed. If there is a problem with the gears or bearings of the hydraulic pump, which causes periodic changes in the hydraulic system pressure it will also cause resonance in the hydraulic system and generate noise.Reason: Cleaning method for internal leakage in the oil cylinder: Replace the sealing element of the oil cylinder. The lifting platform does not lower. Reason: The lowering valve is malfunctioning. Cleaning method: When pressing the lowering button, check whether the lowering valve is powered on. If there is no electricity, clean it as much as possible; If there is power, clear the malfunction of the lowering valve itself or replace the lowering valve. The sliding valve should be kept clean and.
