AachenFixed hyReason: 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.
This paper briefly introduces some matters that should be paid attention to in the selection of oil tank for hydraulic elevators. The main functions of the hydraulic oil tank for elevators in the hydraulic systems of hydraulic machinery such as elevators and hydraulic elevators are oil storage, separation of air contained in oil and elimination of foam.
Aachen.On the other hand, under the action of high pressure, the hydraulic system inevitably causes the hydraulic valve to flow back or the sealing components to produce oil. The main reasons for the natural descent of the hydraulic cargo elevator include the following points: replacement of the support valve due to leakage. The lowering valve is damaged or not powered on. Require the lowering valve to be kept clean on a daily basis, and if damaged, replace it with a new hydraulic lowering valve in a timely manner.
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.
.The optional configurations of a fixed lifting platform include manual hydraulic power, movable flip plates that are easy to overlap with surrounding facilities, rolling or motorized roller tracks, safety contact bars to prevent foot rolling, manual or motorized rotating workbenches, hydraulic overturning workbenches, safety support rods to prevent the lifting platform from falling,AachenHydraulic scissor type lifting platform, stainless steel safety nets, electric or hydraulic lifting platform walking power systems, and universal ball countertops.
If the circuit of the device is not disconnected or lowered, it is necessary to check the fuse for repair and replacement.
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.
The use of cleaning oil and the brand used in the system
When using a crane for auxiliary installation, full consideration should be given to whether the on-site environment meets the operating conditions of the crane.
If the circuit of the device is not disconnected or lowered, it is necessary to check the fuse for repair and replacement.
Direct material.The elevator is evenly distributed at any position on the guide rail at 150% of the maximum load capacity, and should be stable at the maximum lifting height.
Separate: Loading and unloading on different platforms.
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, it needs to be corrected. In addition, hydraulic pipelines should use hoses as much as possible, even when arranging pipelines, it can reduce vibration and noise, and the pipelines should avoid dead bends as much as possible.
Regularly check whether each organization is functioning properly and whether there is noise. If problems are found, they should be promptly cleaned up.
Administration.The combined platform is often used in small workshops with small volume of goods. However because this platform needs to complete two functions at the same time,AachenCustomized hydraulic lifting platform, it inevitably increases the distance of handling tools/vehicles in the workshop.
Usage and instructions for steel wire ropes in elevators: The steel wire ropes of the steel wire ropes require very high strength, usually made of high-quality carbon steel with a carbon content of 0.5% -0.8%. They are widely used as transmission components in elevators. Due to its large load-bearing capacity, light weight, smooth operation, no noise,AachenLarge hydraulic lifting platform, suitable for high-speed transmission, high strength strong overload capacity, and reliable operation, it has become a commonly used rope for hydraulic elevators.
When encountering signs of overheating in the electric motor, it is necessary to park the car in a timely manner, clean the problem, and continue running. The motor bearings should be smooth and outstanding.
Aachen. There is air in front of the pilot valve of the elevator overflow valve noise overflow valve. The damping hole on the main valve core of the overflow valve is blocked by oil dirt, low or high hydraulic oil viscosity, and resonance occurs with components in the circuit. Troubleshooting: Strengthen sealing, repeatedly adjust the pressure, Make the damping hole unobstructed, repair or replace the spring, reduce the flow of the remote control port, replace the oil, and other components. The pressure setting of other components should not be similar to the pressure setting of the relief valve. 5. The noise of the elevator pipeline is usually caused by excessive dead bends or loose fixed sleeves in the hydraulic pipeline.
