Fault characteristics of rotary electric actuator
1. Faults in the debugging stage: The faults of newly purchased electric actuators are more complicated, and are characterized by the intertwining of quality issues such as the design, manufacturing, installation, and management of the electric actuator manufacturer.
2. Early and mid-term operation failures: Generally, during mid-term operation, system components/components are in good working condition and the failure rate is low.
3. Late-run failure: After the quarter-turn electric actuator has been running for a period of time, due to the difference in operating frequency and load conditions, various components/components wear exceeding the standard. At this stage, the fault characteristics of electric actuators are poor position feedback contact, poor positioning accuracy, decreased stability, significantly reduced efficiency, and a gradual increase in failure rate.
