Our goal: to be a high-quality manufacturer of industrial control valves, gaining unanimous recognition from new and old customers
Our mission: To fully utilize the effectiveness of industrial control valves to achieve better results
An electric actuator is a driving device that can provide rotary or linear motion, and it uses certain driving energy to work under signal control. The actuator uses electric power to convert the actuator through a cylinder or motor. The basic types are partial rotation, linear path, and multiple rotation. We all know that any product will maintain its performance and service life as long as it is properly maintained, so how should we maintain it when using electric actuators?
According to the data published in the US military standard mil-hdbk-338, the main failures of electric actuators occur in bearings and motors, so we need to maintain these aspects.
1. Clean and maintain the lubricating oil.
An important feature of electric actuators is that they are lubricated by lubricating oil, but the viscosity of the lubricating oil varies with the temperature of the oil. Low viscosity can lead to increased wear of gears, worm gears, and worm gear transmission components, leading to a serious decline in transmission accuracy. Excessive viscosity can lead to performance degradation. However, in practical operation, it is very difficult to clean and maintain the lubricating oil. The wear of the worm gear, worm gear, and gear components, such as aging of water impurities, corrosion, and inner layer peeling, will seriously affect the purity of the lubricating oil. Therefore, the cleanliness of the lubricating oil should be regularly checked, and if there is any abnormality, it should be replaced in a timely manner.
2. Timely handle grease leakage
Due to the rapid action and high frequency of electric actuator products, they will inevitably be affected by some external shocks, which is one of the important reasons for lubricating oil leakage. Once we find lubricating oil leakage, we should promptly handle it.
3. Improve the working environment and conditions of electric actuators
The performance and service life of electric actuators are inseparable from the working environment. Only by focusing on improving the working environment and maintaining the use conditions can the service life be greatly extended.
3. Failure to strengthen maintenance at the initial stage
Electric actuators have a high failure rate in the early stages of use, and early failures are generally caused by design, manufacturing, and installation errors. These early failures are difficult to detect and resolve. Therefore, special attention should be paid to the maintenance of initial failures.
