Maintenance precautions for electric linear actuators- Ningbo Alpha Automation Co., Ltd.

As a key component of modern automation control systems, the stability of electric linear actuators has an important impact on the efficiency and safety of production lines. Therefore, implementing a professional maintenance strategy is essential to ensure the long-term reliable operation of electric linear actuators.

Regular inspection and preventive maintenance
Appearance inspection
Regular appearance inspection of electric linear actuators is an important part of maintenance work. During the inspection, attention should be paid to whether there are signs of cracks, deformation, corrosion or wear. These surface problems may indicate potential structural defects or wear. If abnormalities are found, appropriate measures should be taken in time to deal with them.
Fastener inspection
All fasteners, including screws, nuts and connectors, need to be checked regularly to ensure that they are in good tightening condition. Loose fasteners will not only cause vibration and noise, but may also cause component damage and affect the overall performance of the actuator.
Cable and wiring inspection
It is essential to check the integrity of cables and wiring. Make sure there is no damage, aging or looseness, and ensure that the cables are well shielded and grounded to reduce the risk of electromagnetic interference and ensure the safety of the equipment.
Lubrication and cleaning
Regularly lubricate the moving parts of the actuator according to the manufacturer's recommendations to reduce friction and wear. In addition, keep the actuator and its surroundings clean to prevent contaminants such as dust and debris from entering the equipment, thereby extending the service life of the equipment.

Performance Monitoring and Adjustment
Stroke and Limit Monitoring
Regularly checking the accuracy and reliability of the actuator's stroke and limit switches is key to ensuring the normal operation of the system. If stroke deviation or limit switch failure is found, it is necessary to adjust or replace it immediately to avoid further damage to the equipment.
Speed and Load Monitoring
Monitor the operating speed and load capacity of the actuator to ensure that it operates within the design parameters. If a speed drop or insufficient load capacity is detected, this may be a sign of wear on the transmission components or deterioration in motor performance, and further inspection and repair are required.
Feedback Signal Monitoring
The accuracy and stability of the actuator's feedback signal are critical to the overall performance of the control system. Check the feedback signal regularly, and if any abnormality is found, the cause should be immediately identified and repaired to ensure the effectiveness and reliability of the system.

Troubleshooting and Repair
Fault Diagnosis
When an electric linear actuator fails, a comprehensive fault diagnosis is required first. By checking the power supply, control signal, transmission components and sensors, the specific location and cause of the fault can be determined to provide a basis for subsequent repairs.
Repair and Replacement
Based on the fault diagnosis results, repair or replace the faulty parts in a targeted manner. For severely worn parts, such as bearings and gears, they should be replaced in time to ensure the normal operation and stable performance of the actuator.
Testing and Verification
After completing the repair or replacing the parts, the actuator needs to be fully tested and verified to ensure that it can operate stably according to the design requirements. This step is an integral part of the maintenance process to ensure that the equipment is restored to its optimal state.

Maintenance Records and Document Management
Maintenance Records
Establish detailed maintenance records, including maintenance date, content, parts replacement and test results. These records not only help track the maintenance history of the actuator, but also detect potential problems in time and improve the management efficiency of the equipment.
Document Management
Systematically organize and manage relevant documents such as maintenance records, operating manuals, troubleshooting guides, etc. to ensure that relevant personnel can consult them at any time. The transparency and accessibility of this information helps improve the work efficiency and response speed of the team.
