Each brush should be kept clean on its surface, and the brush pressure should be adjusted to ensure that its area is not less than %.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.Koblenz,The hydraulic elevator has no counterweight device, which improves the utilization rate of the well surface.When using hydraulic elevators, hydraulic system failures, electrical equipment or component failures, etc. Today, the manufacturer of hydraulic cargo elevators will introduce to you the reasons for the noise generated by hydraulic elevators.Gbarnga,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.Selection of the location of the loading and unloading lifting platform In order to reduce the cost of material handling,KoblenzFixed hydraulic lifting platform, the location of the platform should be selected to minimize the distance of the handling tools and vehicles in the factory. It is much easier to move a fully loaded transport vehicle to a designated location outside the building than to transport the loaded materials one by one to the designated location indoors. When selecting a platform location, full consideration should be given to the production process and operational needs of the factory. There are two modes of platform layout: merging: loading and unloading on the same platform.Electrical equipment or component failures. Hydraulic elevator manufacturers tell you that the main reasons for high noise generated by electric motors are: bent or severely worn motor rotors, or damaged bearings which cause electric motors to sweep and produce noise; The cooling fan of the electric motor is damaged or not firmly fixed, resulting in high noise; The electric motor is not firmly fixed and can also cause vibration, producing high noise.

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.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, and the pilot valve and valve seat are matched without spring deformation or incorrect installation. The remote control port has excessive oil flow, low or high hydraulic oil viscosity, and resonance occurs with components in the circuit. Troubleshooting: Strengthen sealing repeatedly adjust the pressure,KoblenzLarge hydraulic lifting platform, exhaust and clean the valve body several times, Make the damping hole unobstructed,KoblenzVehicle mounted hydraulic lifting platform, repair or replace the spring, replace the oil and other components. The pressure setting of other components should not be similar to the pressure setting of the relief valve. . The noise of the elevator pipeline is usually caused by excessive dead bends or loose fixed sleeves in the hydraulic pipeline.Quality inspection report,Load bearing capacity: The lifting platform is placed on a horizontal support surface, and the workbench is evenly loaded to % of the maximum load capacity. After lifting times, each load-bearing component must not have deformation or cracks.If the circuit of the device is not disconnected or lowered, it is necessary to check the fuse for repair and replacement.Surface paint quality: The paint should be smooth and flat, have good adhesion with metal, have uniform color, no bubbles, no cracks, pits, paint leakage, and sagging.

The installation personnel should confirm and count the equipment details, confirm that there are no omissions in the shipped equipment details, check if the tools are complete, and ensure the smooth progress of the installation process.Manufacturing cost,The use of cleaning oil and the brand used in the systemHydraulic elevators and load-bearing oil cylinders can directly act on the foundation pit, requiring low shaft strength, and brick or brick concrete structure shafts.Due to damage to the gear pump of the lifting cargo elevator equipment and no pressure lifting. Replace the gear pump.Koblenz,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.Regularly check all wires and cables for damage. It is necessary to wrap and replace the damaged parts in a timely manner.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 V. 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.
