In today's society, the role of working on aerial work platforms cannot be ignored. Everywhere in life is inseparable from the help and assistance of aerial work platforms. However, the aerial work platform is not a god-made perpetual motion machine. It can also become sick and emotional, and there are many ways to judge its abnormal work. Let's learn how to diagnose and deal with abnormal working aerial work platforms.
The aerial work platform will emit some sounds during the operation. Different sounds reflect the real-time working conditions of various parts of the aerial work platform.
Specifically:
1. The aerial work platform makes a loud sound
This sound shows that the bearing speed of the lifting mechanism of the aerial work platform has changed, and the surface of the parts has ripples. Improve the surface condition of the bearing raceway, you can reduce the occurrence of this sound.
2. The high-altitude operation platform makes a pattering sound
This sound is formed by the collision between the cage and the rolling element. When the moment, load or radial clearance is large, it will easily produce a pattering sound. Increasing the accuracy of the retainer, choosing a bearing with a small clearance or applying a preload to the bearing, reducing the torque load, reducing the installation error, and selecting a good lubricant can reduce the occurrence of this sound.
3. The buzzing sound of the aerial work platform
The buzzing sound when starting or shutting down indicates that the pump station is running without load, and the axial vibration of the pump station is abnormal. This is mainly because the axial vibration is affected when the shaft aligning performance is not good. Unstable vibration.
