Maintenance of electric actuators mainly includes the following aspects:
Electrical connection and control system maintenance: Regularly check the electrical connection, including cables, terminals and motors, to ensure good connection, no looseness or corrosion, and prevent electrical failure. At the same time, regularly check the status of the control system, including controllers, communication modules, etc., to ensure their normal operation, and update the software or firmware in time to improve the stability of the system.
Mechanical parts and transmission system maintenance: Regularly add appropriate amount of lubricating oil or grease to the bearings, gears, transmission belts and other transmission parts of the electric actuator to ensure the flexibility of the moving parts and reduce friction. At the same time, check mechanical parts such as valves and pistons to ensure that they have no abnormal resistance or jamming during movement, and replace parts with severe wear in time.
Appearance and cleaning maintenance: Regularly clean the external surface of the electric actuator to prevent dust, oil and other dirt from affecting the heat dissipation and normal operation of the equipment. Avoid using sharp tools that may damage the surface.
Position sensor and calibration: Regularly check the performance of the sensor to ensure its accuracy and sensitivity. Regularly calibrate the stroke and position of the mechanism to ensure its consistency with the set value.
Lubricant cleanliness management: The viscosity of the lubricant changes with the oil temperature. Too low viscosity will cause increased wear of the transmission parts, and too high viscosity will cause greater movement resistance. Regularly replace the lubricant to ensure the normal operation of the mechanical parts of the electric actuator.
Improve the working environment and operating standards: The characteristics and service life of the actuator are closely related to the operating environment and the professional level of the operator. Only by improving the actuator and maintenance application standards and strengthening personnel training can the service life be greatly increased.
Regularly check and calibrate the electronic control module: Check whether the wire connection is intact and the power supply voltage is stable to ensure the normal operation of the electric actuator. Electric actuators working in harsh environments should pay more attention to daily maintenance.
Monthly maintenance and inspection content: Including checking the appearance of the equipment, the indication status of the control valve, the position of the electric valve, each connecting wire and flexible pipe, the grounding of the equipment, the rust of the connecting parts, whether there is water in the equipment, leakage, etc., and record them in the technical files.
