ChifengSelf prRegularly check whether each organization is functioning properly and whether there is noise. If problems are found, they should be promptly cleaned up.
Therefore, in the hydraulic pipeline assembly line, rainstorm, thunder, fog and other bad weather, the work at heights in the open air shall be stopped at the boarding bridge.
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,ChifengElectric fixed hydraulic lifting platform, 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.
.The 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,ChifengScissor type hydraulic lifting platform, 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.
Voltage too low: Measure the starter voltage, with an allowable fluctuation range of± 10%.
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.
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 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.
The manufacturer of hydraulic cargo elevators tells you the reason for the instability of hydraulic lifting equipment. Hangzhou hydraulic cargo elevator equipment has always had good stability, mainly used for heavy types of goods. However, during use, Hangzhou hydraulic cargo elevators may inevitably encounter some faults during the lifting process, such as very unstable conditions. What is the reason for the instability of the elevator? How to solve these problems?
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, 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!
investment.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)
After long-term use of the automatic lifting platform equipment, it is inevitable that some malfunctions will occur. In order not to affect work, it is necessary to promptly solve the difficulties in starting the motor and abnormal sounds. Generally, due to overload, insufficient power supply, and a small cross-sectional area of the power supply cable, the starting voltage drop is too large and the price of the cargo elevator is reduced.
The smoothness of the gearbox, gearbox, external meshing gears, and hydraulic oil are all carried out according to the requirements in the smoothness table.
The precautions to consider when selecting a hydraulic lift oil tank include: considering the structure of the oil tank, the partition in the traditional oil tank cannot settle dirt. A vertical partition should be installed along the longitudinal axis of the oil tank, with a space left between one end of the partition and the end plate of the oil tank to connect the gaps on both sides of the partition. The inlet and outlet of the hydraulic pump are arranged on both sides of the partition at the disconnected end, so that the distance Z between the inlet and return oil is far, The hydraulic oil tank has more heat dissipation effect.
Recommendation and consultation.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, heat dissipation, separation of air contained in oil and elimination of foam.
When working at heights,ChifengMicro hydraulic lifting platform, except for relevant personnel, no one is allowed to walk or stay below the workplace. Fencing or other protective devices should be installed below the workplace to prevent falling objects from injuring people.
When encountering signs of overheating in the electric motor, it is necessary to park the car in a timely manner, clean the problem, 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 manufacturer of hydraulic cargo elevators will tell you about the knowledge of specialized lifting platforms for unloading.
The guide rail type elevator has a structure of a straight top oil cylinder. The linear operation of the oil cylinder pulls the transmission chain, with the advantages of higher lifting height stable operation, and simple maintenance compared to the scissor fork type elevator.
