ChekhanovSmallThe 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, and speed switching circuits.
Therefore the wholesale manufacturers of hydraulic elevators remind that there are three main ways to adjust the speed control circuit: throttling speed control circuit: quantitative pump oil supply, the oil is supplied by the pressure limiting variable pump, and the flow rate into the actuator is adjusted by the flow valve to adapt the flow rate of the variable pump to the regulated flow rate of the speed control valve.
Chekhanov.If any problems are found, please contact the manufacturer in a timely manner to avoid exceeding the warranty period.
Mobile is a type of cargo heavy machinery equipment with good adjustment reliability and wide application fields, suitable for automated production lines
.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.
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,ChekhanovHydraulic lifting platform for loading, the oil seal or straightening rod must be replaced in a timely manner.
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.
Regularly inspect the hydraulic lifting equipment of the upper and lower materials to ensure the safety of the rail type elevator and the safety of the material supply to the rail type lifting platform.
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 cargo elevators have been used in some high-altitude operations in recent years, and now some hydraulic cargo elevators are gradually mentioned as large machinery such as tower cranes, becoming a better choice for some high-altitude operations. However, there are still certain limitations, such as height and improving the quality of goods, which have certain constraints.
Installation material list. 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, and the depth should not exceed 0.4mm.
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.
Reason: The lowering speed valve is out of adjustment. Cleaning method: If the lowering speed valve is adjusted, and if the adjustment is ineffective, replace it with a new valve.
analysis.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%.
Carefully prepare a special construction plan for installation and construction, and provide safety technical disclosure to installation personnel.
The elevator itself has a simple structure and is easy to maintain, which has been favored by a large number of enterprises and individual customers. Hydraulic elevator is a multifunctional heavy loading and unloading mechanical equipment. The lifting system of hydraulic elevators is driven by hydraulic pressure, also known as hydraulic powered elevators.
Chekhanov.Do you know the classification of simple cargo elevator lifting platforms? The manufacturer of the hydraulic cargo elevator is here to inform you.
I believe many people want to know about the maintenance issues of guide rail hydraulic lifting platforms,ChekhanovHydraulic lifting platform truck, as it is related to their service life. During use, frequently check the connection of each part. If loose, tighten it. When the body is under pressure 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.
Pay attention to checking each steel wire rope for signs of broken wires and loose drums. If it exceeds the relevant rules, it is necessary to replace it immediately. The protection of steel wire ropes should strictly follow the rules of GB5144-85.
