OberhausenLogi
OberhausenFixeHydraulic elevator manufacturers remind us that the basic principle of the hydraulic elevator speed control circuit is that the system often needs to adjust the movement speed of the hydraulic cylinder and hydraulic motor to adapt to the working cycle needs of the main machine. The speed of hydraulic cylinders and hydraulic motors depends on the displacement and input flow rate. It can be seen that changing the flow rate or displacement can affect the speed of the cylinder and motor.
The characteristics of the platform include reliable hydraulic system, simple operation, large load-bearing capacity, and rear hinge support.
Oberhausen.This product has a solid structure, high load-bearing capacity, smooth lifting, easy installation and maintenance, and is an ideal cargo transportation equipment for replacing elevators on lower floors.
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.
.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 the pre installation is completed, the pre installed equipment should be fixed, and the positions of cables, oil pipes, and components such as the pre installed frame should be confirmed to be correct before reinforcement work can be carried out. Reinforcement requires welding or screws, and the hydraulic cargo elevator after reinforcement has robustness and safety.
Considering the oil level in the oil tank, when all hydraulic cylinders in the system are extended, the oil level in the oil tank should not be lower than the Z-low oil level, and when the oil cylinders retract, the oil level should not be higher than the Z-high oil level. In fact, most manufacturers have noticed the above issues. The reason for the introduction is that most users can learn more about the equipment itself when using elevators, in order to facilitate equipment maintenance. Hydraulic cargo elevator manufacturers sincerely hope that you choose a legitimate manufacturer when purchasing elevators, to avoid any worries about after-sales service.
Emergency descent device: When a power driven chain elevator loses power, there should be a device to make the workbench emergency descend.
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, such as very unstable conditions. What is the reason for the instability of the elevator? How to solve these problems?
Regularly check whether each organization is functioning properly and whether there is noise. If problems are found, they should be promptly cleaned up.
Manufacturing cost.The cylinder head oil seal is too tight or the rod is bent, which can also cause noise during movement due to other forces. At this point, the oil seal or straightening rod must be replaced in a timely manner.
Check valve leakage: If the natural wear of the check valve exceeds the specified value after long-term use, it will cause leakage. Disassemble and clean the check valve, and replace it if necessary.
The speed circuit is the circuit that switches the motion speed and speed of the actuator in the hydraulic system of the guide rail hydraulic lifting platform. Mainly including valves, pumps, and actuators. The commonly used speed circuits include speed circuits, high-speed circuits and speed switching circuits.
When the hydraulic oil of the equipment is insufficient,OberhausenHydraulic lifting platform and hydraulic lifting platform, it will not cause lifting. At this point, you only need to add enough hydraulic oil to run.
Supply chain quality management.Motor not running: Check all components of the motor for damage and check if there are any problems with the circuit and wiring.
Hydraulic cargo elevator: Only when the load of the hydraulic guide rail type lifting cargo elevator cannot start working, should the pressure of the hydraulic system be checked. If the pressure is below the normal range, the set value of the relief valve should be adjusted. Professional elevator manufacturers have high pressure resistance, good waterproof performance, fire and high temperature resistance, strong overload capacity, corrosion resistance, radiation resistance, and long service life
Hydraulic lifting table: the hydraulic lifting table is widely used in various industrial enterprises and production lines such as automobile, wood processing, chemical filling, etc., to meet the lifting needs of different operation heights, and can be equipped with various table forms (such as ball, roller, rotary table, steering, tipping, telescoping) and with various ways (separate,OberhausenHydraulic lifting table small, linkage, explosion-proof), it has stable and accurate lifting, making production operations smooth.
Oberhausen.Solution: Check if the performance of the legs is good, even if the butter is polished to increase its properties.
Oil leakage is a common malfunction. Due to loose joints or damaged sealing rings, oil leakage may occur. Therefore, this fault can be solved by tightening the oil leakage joint or replacing the damaged sealing ring.
The noise and oil level of the elevator oil cylinder are too low. From the air at the connection of the oil filter or joint to the oil, the coupling inside the oil cylinder is loose. The internal fault of the oil cylinder is that the installation of the oil cylinder motor is not concentric. From the motor, the air and oil at the moving shaft are blocked. The oil return pipe of the oil filter is loose, and the air or oil pipe is on the oil surface, Mixing air into the oil to eliminate: The concentricity should be adjusted to within 0.1MM. The coupling should be repaired or the oil pump should be replaced to increase the oil volume above 400mm in the oil filter and joint positions. The rotating shaft sealing ring should be replaced to clean the oil filter screen, filter the oil, lock the return oil pipeline, and extend the return oil pipeline below the oil level. If there is air mixed in the oil or the air in the hydraulic cylinder is not completely discharged, it will cause cavitation under high pressure and cause significant noise. At this point it is necessary to exhaust the air in a timely manner.
