AnthonyCustomiThe above are the working principles of three common elevators, and there are also some forms of elevators that are not common, such as cylinder mounted elevators, curved arm elevators car mounted elevators, etc. Their common feature is the hydraulic principle for operation, 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.
Lines of various safety equipment
Anthony.Check valve leakage oil pipe check valve leakage. The solution is to carefully check whether the one-way valve is functioning properly. If it is not normal, it is recommended to replace the one-way valve with a new one.
Therefore, the wholesale manufacturers of hydraulic elevators remind that there are three main ways to adjust the speed control circuit: throttling speed control circuit: quantitative pump oil supply, using flow valves to adjust the flow in and out of the actuator to achieve speed control; In the volume throttling speed control circuit, the oil is supplied by the pressure limiting variable pump, and the flow rate into the actuator is adjusted by the flow valve to adapt the flow rate of the variable pump to the regulated flow rate of the speed control valve.
.The hydraulic lifting platform often checks the connection status of each part, and if there is any looseness, attention should be paid to ensuring that the centerline of the reverse organization reducer is parallel to the centerline of the gear, and its meshing surface is not less than 70%. The meshing gap should be appropriate.
Reason: The lowering valve is not tightly closed. Cleaning method: Check if the lowering valve is powered on. If there is no power supply, clear the malfunction of the lowering valve itself or replace the lowering valve. It is necessary to keep the valve of the lowering valve clean and flexible.
Oil leakage from the oil cylinder: If it is a problem with the sealing ring, replace the sealing ring. If there are debris or debris on the oil cylinder it is recommended to replace it with a new one.
There is a possibility of hydraulic system leakage. Check the hydraulic system for leaks, with a focus on checking the hydraulic pipes and joints, and hydraulic valve connections. If hydraulic oil leaks, replace them with composite pads or disturb unprocessed raw materials.
Hydraulic lift cargo elevators belong to high-altitude work equipment. Small shaking of the scissor type structure is normal, but excessive deviation is a symptom. It is necessary to find the cause and make correct judgments in a timely manner. Generally speaking, operations above 8 meters are generally allowed. Due to its own weight, devices above this height begin to vibrate in different ranges. The vibration range depends on factors such as weight,AnthonyManual hydraulic lifting platform, lifting height, and intensity of high-altitude operations.
Work courses.Due to damage to the gear pump of the lifting cargo elevator equipment and no pressure lifting. Replace the gear pump.
Volume speed control circuit: Speed control is achieved by adjusting the displacement of a variable pump or variable motor.

The vibration range depends on factors such as weight, lifting height,Anthony10 meter lifting hydraulic platform, and intensity of high-altitude operations.
The lifting platform is placed on a horizontal support surface,AnthonyElectric lifting platform Hydraulic lifting platform, and the concentrated load of MAX load capacity is placed at any position 300mm away from the periphery of the workbench. After lifting 100 times, each load-bearing component must not have deformation or cracks.
project.If the circuit of the device is not disconnected or lowered, it is necessary to check the fuse for repair and replacement.
Based on the foundation plan, pay attention to alignment, leveling, and alignment to ensure the foundation level and various usage requirements. The access road for external construction elevators should be flat and have sufficient space for equipment parking.
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, producing high noise.
Anthony.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.
The classification of lifting platforms is as follows: they are divided into mobile lifting platforms, automatic lifting platforms, hydraulic lifting platforms, folding arm lifting platforms, and sleeve type lifting platforms according to their different modes of movement.
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.
