For hydraulic cylinders in hydraulic elevators, 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.Surface paint quality: The paint should be smooth and flat, have uniform color, no bubbles, no cracks and there should be no wrinkles, pits, paint leakage, and sagging.Uden,UdenMobile hydraulic lifting table supply,For example, setting anti fall and interaction can achieve good usage effects. This product is mainly used in various enterprise factories.Do not use hydraulic lifting equipment with malfunctioning issues. The problem should be resolved before carrying cargo.Roquetas de Mar , and the pilot valve and valve seat are matched without spring deformation or incorrect installation. The remote control port has excessive oil flow, low or high hydraulic oil viscosity, and resonance occurs with components in the circuit. Troubleshooting: Strengthen sealing, repeatedly adjust the pressure, exhaust and clean the valve body several times, Make the damping hole unobstructed, repair or replace the spring,UdenFixed hydraulic elevator,Udenhydraulic lift, 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. . The noise of the elevator pipeline is usually caused by excessive dead bends or loose fixed sleeves in the hydraulic pipeline.There are many reasons for unstable workbench descent, such as overload, unstable support, severe eccentric load, hydraulic oil impurities, etc. In response to the above reasons, it can be solved by reducing the load, adjusting the center of gravity of the load, and replacing hydraulic oil wholesale for hydraulic cargo elevators. 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 meters, if possible, please use safety protection measures
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.Firstly, rust prevention is necessary. Because the part of the hydraulic cylinder needs to extend out of the cylinder during operation, it will naturally be corroded by oxides and acidic gases. This requires us to apply an appropriate amount of grease to protect it from erosion as a weight component. If we change the oil, we must open the box and use it for a long time to prevent the hydraulic cylinder from being used for a long time. In the operation of hydraulic cylinders, the speed should be appropriate and should not exceed m/s to extend the service life of the hydraulic cylinder. In addition, in order to protect the mechanism and safety, it is very important to install buffer devices internally to protect the hydraulic cylinder. The greater the pressure of the protective hydraulic cylinder, and the greater its pressure. A specialized product manufacturing enterprise that integrates research and development, as well as service. A long-term professional elevator manufacturerWhen using hydraulic elevators, the main causes of noise are mechanical mechanism failures, hydraulic system failures electrical equipment or component failures, etc. Today,Separate: Loading and unloading on different platforms. 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, and resonance occurs with components in the circuit. Troubleshooting: Strengthen sealing low or high hydraulic oil viscosity, repeatedly adjust the pressure, exhaust and clean the valve body several times, 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. . The noise of the elevator pipeline is usually caused by excessive dead bends or loose fixed sleeves in the hydraulic pipeline.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, speed up the flow of materials, and obtain greater economic benefits.
When encountering signs of overheating in the electric motor, it is necessary to park the car in a timely manner, and continue running. The motor bearings should be smooth and outstanding.Click to view,The lifting platform is placed on a horizontal support surface, and the concentrated load of MAX load capacity is placed at any position mm away from the periphery of the workbench. After lifting times, each load-bearing component must not have deformation or cracks.When maintaining hydraulic components, the workbench must be clean. The purpose of the inspection tool.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.Uden,Voltage too low: Measure the starter voltage, with an allowable fluctuation range of± %.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.The contact of the travel switch must be firmly opened and closed, and the contact crater should be polished in a timely manner.
