Knowledge about the inspection and analysis of pneumatic shafts is brought to you, for detailed information, please refer to the following:

(1) Understand the circumstances of the fault occurrence, the working condition prior to the fault, and the symptoms post-fault.

(2) Conduct a thorough analysis of the cause or scope of the fault, identifying the root cause or analyzing the fault's scope.

(3) Conduct external inspections of the air-inflated shaft, focusing on the tightness of fixing screws and wiring screws for fuses, relays, contactors, and travel switches, checking for any broken wires, signs of burnout on the money ring, or welding of contact points, and ensuring the mechanical parts of the electrical device operate smoothly. Promptly address any apparent malfunctions.

(4) Power-off inspections are primarily conducted to identify latent faults. Typically, a multimeter's resistance range is used to check for open circuits, short circuits, or grounding issues in the components and circuits of the fault area. In some cases, a megger and other devices can also be utilized for inspection. If the cause of the fault cannot be found during the power-off inspection, an energized inspection can be performed.

(5) Power-on inspections are primarily conducted to identify undetectable faults. These inspections should be carried out without any load to prevent accidents.
