Harlem 10 meteThe 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.
Mobile is a type of cargo heavy machinery equipment with good adjustment reliability and wide application fields, suitable for automated production lines
Harlem .Many operating factories often require the use of hydraulic cargo elevators, which can be lifted and lowered making it very convenient to use. Many people do not know the knowledge of hydraulic cargo elevator lifting and adjustment. If they understand this knowledge, it will be helpful for future maintenance. The power unit of the fixed chain elevator for hydraulic lifting of cargo elevators drives the hydraulic oil to generate pressure, causing the oil cylinder to move back and forth to drive the lifting platform, thus achieving the adjustment of lifting speed. The power unit adjustment, whether it is a scissor type lifting platform or a track type lifting platform, is composed of the power unit and the oil cylinder. The power unit is manufactured with four outlet holes, which can be adjusted in size to increase or decrease the hydraulic oil flow rate of the oil cylinder, Adjustable motor speed or electro-hydraulic proportional valve to adjust hydraulic oil flow rate; The longer the oil pipe and hydraulic oil pipe, the longer the rise time. So during installation, try to minimize the length of the pipeline within the allowable range of the design; On the basis of adjusting the power device, the size of the oil pipeline can also be adjusted, and corresponding adjustments can be made while ensuring that the equipment meets normal demand and safety.
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, container, mold manufacturing, wood processing, 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, linkage, explosion-proof), it has stable and accurate lifting, frequent starting The characteristics of large load capacity effectively solve various lifting and lowering difficulties in industrial enterprises, making production operations smooth.
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.
I believe many people want to know about the maintenance issues of guide rail hydraulic lifting platforms, as it is related to their service life. During use, frequently check the connection of each part. If loose, the tightness of the connecting bolts of the body should be checked (the pressure state that can be used). All connecting shafts should have split pins and hydraulic cargo elevators should be fully opened.
. The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic directional valve, and the return oil from the lower end of the hydraulic cylinder returns to the oil tank through the balance valve, throttle valve, and explosion-proof electromagnetic directional valve. In order to ensure a smooth descent of heavy objects and safe and reliable braking, a balance valve and balance circuit are installed on the return oil circuit to maintain pressure and ensure that the descent speed is not affected by changes in heavy objects. The throttle valve regulates the flow rate and the lifting speed. To ensure safe and reliable braking and prevent accidents, a hydraulic one-way valve, also known as a hydraulic lock is added to ensure safe self-locking when the hydraulic pipeline bursts. Install an overload sound alarm to distinguish between overload or equipment failure.
When the hydraulic cargo elevator needs to work, first connect the power supply and press the button to drive the motor of the hydraulic power unit to drive the gear pump. The hydraulic oil forms a certain pressure through the vane pump and passes through the oil filter; Explosion proof electromagnetic directional valve; Throttle valve; Hydraulic control one-way valve; The balance valve enters the lower end of the hydraulic cylinder, causing it to move upwards and lift heavy objects. The hydraulic cylinder moves downwards (i.e. the weight drops), the explosion-proof electromagnetic directional valve of the hydraulic oil enters the upper end of the hydraulic cylinder, and the return oil from the lower end of the hydraulic cylinder passes through the balance valve; Hydraulic control one-way valve; Throttle valve, explosion-proof electromagnetic directional valve.
When using hydraulic elevators, frequent inspections and maintenance should be carried out, which not only extends the service life of the hydraulic elevator but also enables it to exert greater power during operation. Of course, hydraulic elevators also have their own regular repair times and protection methods: regular protection (carried out per shift).
Information recommendation.Therefore, in the hydraulic pipeline assembly line, it is necessary to avoid dead bends as much as possible and check the tightness of the sleeve in a timely manner.
Road noise can also occur if tires are crushed against objects that are prone to noise. The shaking amplitude of the scissor type lifting platform is proportional to its lifting height. The higher the height, the greater the shaking. When using it at a working height of 10 meters, if possible, please use safety protection measures
Hydraulic lifting table: the hydraulic lifting table is widely used in various industrial enterprises and production lines such as automobile, container, mold manufacturing wood processing, chemical filling, 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, linkage, explosion-proof),Harlem 3-meter hydraulic lifting platform, it has stable and accurate lifting, frequent starting The characteristics of large load capacity effectively solve various lifting and lowering difficulties in industrial enterprises, making production operations smooth.
Motor not running: Check all components of the motor for damage and check if there are any problems with the circuit and wiring.
Workshop cost.For hydraulic cylinders in hydraulic elevators,Harlem Mobile elevator hydraulic lifting platform, it is not practical to change their effective working area A (equivalent to displacement) to adjust the speed. Generally, the speed can only be adjusted by changing the flow rate. For variable displacement motors, speed regulation can change both the flow rate and the motor displacement.
In addition the convenience of the layout is also a very important issue. For example, in areas with large or high waves, 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, 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, but if it is too large this form can be considered in places with large drops. The sudden deafness oil type on the head can reduce the installation height, 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.
Solution: Check if the performance of the legs is good, even if the butter is polished to increase its properties.
Harlem .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.
Remember not to overload, overload is the root cause of many faults.
Lifting mechanism: The workbench should be ensured to rise and fall smoothly, and there should be no jumping lifting phenomenon. All moving parts should be flexible when moving, and there should be no jamming devices. The lifting system of the elevator is divided into electric or manual hydraulic systems, and there should be no leakage at all components, pipelines, and joints.
