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.
Naples.Below, we will analyze for everyone. According to the market survey and understanding conducted by the editor of hydraulic freight elevator manufacturers, many customers choose hydraulic elevators instead of elevators due to the following reasons: narrow transportation location, which cannot meet the requirements of elevators; Unable to excavate the elevator shaft at the working location; Elevators are expensive and difficult to meet their needs.
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,NaplesHydraulic small lifting platform, to avoid any worries about after-sales service.
.Aluminum alloy elevators are different from other forms. This type of elevator is made of aluminum alloy material, and can only provide support for 1-2 people.
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.
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.
Introduction to the unloading lifting platform: The unloading lifting platform is a specialized auxiliary equipment used in conjunction with forklifts for cargo loading and unloading. With it, forklifts can directly drive from the ground into the interior of car compartments for batch loading and unloading operations. The warehouse unloading platform products use manual hydraulic power and do not require power supply. Only one person needs to operate to achieve safe and fast loading and unloading of goods. It can reduce a lot of labor, improve the efficiency of loading and unloading operations, and obtain greater economic benefits.
Hydraulic oil deteriorates or produces impurities. After long-term use of oil pressure, there may be impurities or deterioration in the oil. Sampling inspection should be carried out to see if there are solid particles, discoloration and odor. If necessary, the oil should be changed. There may be blockage in the hydraulic pipeline of the hydraulic cargo elevator. The hydraulic pipeline is also a very important part, and it is necessary to check whether the hydraulic pipeline is smooth. Focus on checking whether each type of hydraulic valve includes one-way globe valve, electromagnetic directional valve, proportional control valve, overflow valve, etc. If there are problems, the hydraulic valve should be cleaned or replaced 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 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.
where.New reference wiring diagram 2. Elevator leg noise. Mobile elevators should open the legs before operation. In this case, if the legs lack butter, noise will be generated.
The electromagnetic coil of the electromagnetic directional valve is not firmly fixed, and frequent separation and suction can also produce high noise.
Lifting mechanism: The workbench should be ensured to rise and fall smoothly, and there should be no leakage at all components, pipelines, and joints.
The hydraulic elevator overflow valve can also generate high noise. When air is mixed in hydraulic oil, the overflow valve is stuck or severely worn, the spring of the overflow valve is fatigued and deformed, resulting in unstable pressure regulation of the overflow valve, and the relief time of the overflow valve is too short, it is easy to cause the pilot valve performance of the overflow valve to be partially stable, causing air to vibrate inside the pilot valve and generate noise. So we need to regularly clean the overflow valve. When the overflow valve is damaged or severely worn, it should be replaced.
demand.Before installation, the installation personnel should confirm the infrastructure such as the foundation and shaft, pay attention to alignment, leveling, and alignment points, and confirm that the foundation meets the requirements before construction.
In addition, the convenience of the layout is also a very important issue. For example, in areas with large or high waves,NaplesHydraulic small lifting platform, there may be layout issues when using a lifting mechanism. At this point, in order to facilitate the arrangement and prevent the hydraulic cargo elevator cylinder from being eroded by waves, a lifting structure should be selected to determine the installation position of the oil shoulder, as the lifting point of the bridge is not in a straight line during the lifting process. Therefore, during the lifting process of the cylinder, the connection between the two ends of the cylinder and other components must be hinged in the same square. In addition, the installation of the hydraulic cargo elevator cylinder must also be determined through comparison and calculation, whether it is the tail lifting ear type, the middle pin shaft type or the head pin shaft type. The main advantage is that the effective area of the cylinder is large, and the overall installation height is low. The disadvantage is that if the cylinder stroke is large, there may be stability issues with the cylinder, and the cylinder layout may be difficult. The main advantage of the hydraulic cargo elevator lifting mechanism is that it does not have a stable transmission installation frame for height measurement. Therefore, this form can be considered in places with large drops. The sudden deafness oil type on the head can reduce the installation height, but if it is too large, the oil cylinder will experience an increase in force due to the lifting height. Moreover, the higher the lifting height, the faster the increase in force, which is not suitable for the use of the oil cylinder. Therefore, when it is too large the head pin type is not suitable. In order to comprehensively consider the height of the installation bracket and the force on the oil cylinder during the lifting process, an intermediate installation method can be considered and the installation position can be set at an appropriate height according to calculations.
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.
