XinfuHydraulic
XinfuHydraulicThe 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.
When using hydraulic elevators, the main causes of noise are mechanical mechanism failures,XinfuHydraulic lifting platform frame, etc. Today, the manufacturer of hydraulic cargo elevators will introduce to you the reasons for the noise generated by hydraulic elevators.
Xinfu.There are two reasons for the sinking of the hydraulic cargo elevator table: on the one hand, the hydraulic pressure is flexible, and under high pressure or temperature, the volume will change, which is reflected in the lowering of the position on the table.
When installing disassembling, attention should be paid to ensuring that the middle line is parallel to the middle line of the gear and adjusting the rotating mechanism, and its meshing surface is not less than 70%. The meshing clearance should be suitable for the brakes of each mechanism. The clearance between the brake wheels should be regularly checked and adjusted to ensure its flexibility and reliability. There must be no dirt on the friction surface and it must be cleaned with gasoline or diluent.
.Vehicle mounted lifting platform is widely used for high-altitude operations in hotels, buildings, airports, stations, sports venues, workshops, warehouses, and other places; It can also be used as temporary high-altitude lighting, advertising, etc.
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, resulting in high noise; The electric motor is not firmly fixed and can also cause vibration, producing high noise.
The above are the working principles of three common elevators, and there are also some forms of elevators that are not common, 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.
Do you know the classification of simple cargo elevator lifting platforms? The manufacturer of the hydraulic cargo elevator is here to inform you.
Compare the measurement curves and then go to the variable displacement pump or variable speed motor. Long term targeting all types of high-priced elevator manufacturers nationwide with reasonable prices and comprehensive services, we have gained recognition from our customers
Protective device: In case of power or oil circuit failure, there should be a safety rope to prevent the workbench from falling out of control. (Allow controlled descent)
Quality assurance.The electromagnetic coil of the electromagnetic directional valve is not firmly fixed, and frequent separation and suction can also produce high noise.
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, 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, exhaust and clean the valve body several times, Make the damping hole unobstructed, repair or replace the spring, reduce the flow of the remote control port,Xinfu5 ton hydraulic lifting platform, 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.
When the hydraulic lifting platform is working, the load cannot exceed its rated load. When it is raised to a certain height the larger the mass of the object, the greater the shaking
After 5000 hours of elevator operation, carry out medium maintenance on the mechanical and electrical systems.
Quality risk.When the hydraulic lifting platform is working, the load cannot exceed its rated load. When it is raised to a certain height, the larger the mass of the object, the greater the shaking
There is a possibility of hydraulic system leakage. Check the hydraulic system for leaks, with a focus on checking the hydraulic pipes and joints, oil cylinders, and hydraulic valve connections. If hydraulic oil leaks, replace them with composite pads or disturb unprocessed raw materials.
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 50%.
Xinfu.When placing materials on the platform, they should be placed in the middle of the platform as much as possible. The weight of the goods should be within the standard load range of the equipment,XinfuScissor type hydraulic lifting platform, and the volume of the goods should not exceed the platform size of the equipment. Otherwise, materials and lifting platforms may be injured and dangerous accidents may occur. High priced and various specifications of elevator manufacturers provide timely supply, with high cost-effectiveness, and have become the preferred brand for many wire products. Welcome to purchase!
Set up warning lights around the guide rail type hydraulic cargo elevator equipment, and the warning lights will light up to warn operators when loading and unloading materials. Idle personnel are prohibited from entering the operating range.
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, lifting height and intensity of high-altitude operations.
