How to solve the problem of unstable operation of column lift- Ningbo Alpha Automation Co., Ltd.

When conducting an in-depth analysis of the running stability of the Column Lift, it is first necessary to systematically check its potential problems from the perspective of mechanical structure. As the core track for the platform to move up and down, the geometric accuracy, straightness and firmness of the installation of the guide rail system have a vital impact on the overall smoothness of the operation. If the guide rail is bent, misaligned, loose or improperly installed, it will often cause the platform to shake, get stuck or deviate from the track during movement. In order to effectively solve these problems, the guide rail needs to be fully calibrated and reinforced. High-precision laser measuring instruments are used to detect the verticality and parallelism of the track, and the stability of its structure is enhanced by adding limit adjusters or track fixing reinforcements to ensure the smooth operation of the platform.

In terms of the transmission system, the aging, wear or looseness of key components such as chains, wire ropes, pulleys, etc. are also important factors causing unstable operation. The looseness of the chain may cause the platform to feel jumping when it moves up and down, while the wear on the surface of the wire rope or uneven winding may cause the platform to tilt or vibrate. To this end, it is recommended to regularly replace transmission components or adjust the tension to ensure that the chain and sprocket are tightly meshed, and the wire rope is evenly stressed and neatly arranged. At the same time, the pulley block and tensioning device must be fully inspected to ensure that the bearings are not stuck, fully lubricated and correctly installed, so as to ensure smooth operation without abnormal noise.

As the power source of the Column Lift, the stability of the motor system's performance directly affects the speed control and smooth start of the platform during operation. Unstable motor speed, abnormal power output, fluctuations in power supply voltage, and improper inverter parameter settings may all cause discontinuity and vibration during the operation of the platform. To solve such problems, the motor should be tested for insulation and winding resistance, and the power supply line should be checked to ensure that there is no voltage drop, poor cable contact, or abnormal grounding. When using a variable frequency control system, it is necessary to set appropriate acceleration and deceleration time and frequency output curve according to the load change and speed curve to reduce mechanical shock during starting and braking, thereby improving the overall smoothness of operation.

The hydraulic drive system is the key to the smooth operation of the hydraulic column lift. The cleanliness, viscosity and sealing of the hydraulic oil directly affect the operation of the platform. If air or impurities are mixed in the hydraulic oil, it may cause uneven pushing of the hydraulic cylinder, slow movement of the platform or even shaking. Therefore, it is recommended to regularly replace the hydraulic oil that meets the requirements of the equipment, thoroughly clean the oil tank and oil circuit, remove the residual air in the system, and ensure that the sealing ring is intact and leak-free. In addition, it is also necessary to check whether the output pressure of the hydraulic pump is stable and ensure that it works within the specified range to avoid unstable operation of the platform due to excessively high or low pressure.
