RotlingenElectric lifting platform Hydraulic lifting platformThe need for maintenance

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.

Reason: Cleaning method for internal leakage in the oil cylinder: Replace the sealing element of the oil cylinder. The lifting platform does not lower. Reason: The lowering valve is malfunctioning. Cleaning method: When pressing the lowering button, clean it as much as possible; If there is power, clear the malfunction of the lowering valve itself or replace the lowering valve. The sliding valve should be kept clean and.

Rotlingen.In case of strong wind of level 6 or above, rainstorm, thunder, fog and other bad weather, the work at heights in the open air shall be stopped at the boarding bridge.

The development of elevators is at its peak, as many manufacturers have chosen more multi-story buildings to fully utilize the site, so they also need a device to facilitate the improvement of goods.

.To consider its capacity, generally mobile equipment takes 2-3 times the high flow rate of pump Z, and fixed equipment takes 3-4 times.

Stable and widely applicable cargo lifting equipment is mainly used for transporting goods between height differences in production lines; Material online and offline; Adjust the height of the workpiece during assembly; High altitude feeder feeding; Lifting of components during assembly of large equipment; Large machine material and cutting; The warehouse loading and unloading site is equipped with forklift and other transportation vehicles for rapid loading and unloading of goods.

The electromagnetic coil of the electromagnetic directional valve is not firmly fixed, as many manufacturers have chosen more multi-story buildings to fully utilize the site, so they also need a device to facilitate the improvement of goods.

In on-site hydraulic elevators, it is difficult to detect the rising position, middle position, impact noise, and oil film leakage of hydraulic cylinders. Field observations have shown that the excessive lifting speed of the hydraulic cylinder has led to an increase in failure rate, seriously affecting production efficiency. The unstable hydraulic lifting requires an analysis of the hydraulic oil flow rate. Hydraulic pressing oil has poor quality and contains a large amount of impurities which can also prevent slow and unstable lifting. In addition, there are other reasons: lifting the composition of the hydraulic ring. Oil pump, safety valve, directional valve, directional valve, one-way throttle valve (without throttling) and lifting cylinder.

The above are the working principles of three common elevators, and there are also some forms of elevators that are not common, such as cylinder mounted elevators, curved arm elevators, car mounted elevators, etc. Their common feature is the hydraulic principle for operation, because the stability of the hydraulic system can bring better user experience and safer operation to the equipment, which has been favored by many users.

Home page recommendation.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 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.

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,RotlingenMobile elevator hydraulic lifting platform, 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, 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. 5. The noise of the elevator pipeline is usually caused by excessive dead bends or loose fixed sleeves in the hydraulic pipeline.

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.

Inspection requirements.The hydraulic lifting platform often checks the connection status of each part, and if there is any looseness, it should be tightened. The connection bolts of the machine body should be checked for tightness when the elevator body is under pressure (the compression condition can be formed by rotating the arm). All connecting shafts need to have split pins and need to be fully opened.

After 5000 hours of elevator operation, carry out medium maintenance on the mechanical and electrical systems.

Rotlingen.The use of cleaning oil and the brand used in the system

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.
