电动执行机构主要由电机、轴承、齿轮传动和电路控制器组成。其故障主要出现在电机、轴承和齿轮传动部分。电动执行机构的传动部分离不开油脂。例行维护时检查润滑情况。有赃物或渗漏的油脂应更换并添加。

 

 

　　传统的维修有三种类型或层次:被动维修或“坏了就修”的方式，这实际上是一种合理的方式来处理相对低成本、故障率低、故障后果相对较小的设备。下一个层次是预防性维护，它为我们提供了一个严格的流程，定期维护设备，更换机油、润滑脂、过滤器和密封件，清洗一切。小的出现,与中央系统的可靠的传感器和方法给了我们***好的方法来保持今天的关键部件——预见性维护,没有规定的服务间隔,但设备本身告诉我们当需要维护并确保它继续进行高效、可靠的完成其工作。

 

　　预防性维护

 

　　对于电动执行器，需要考虑很多因素——密封、油脂、可逆接触器和机械部件，系统内部所需的预防性维护是通过数据记录和传感器测量的结合来确定的。显然,每个执行器将运行在一个稍微不同的负载,我们可以记录的数量开始,革命的轴的数量,设备已经运行的时间,和输出速度,所有这些可以预测当换向接触器和执行机构机械结构需要维护。我们不能直接测量油脂的状况，但我们可以测量作动器各点的振动、温度和扭矩，从中得到机器的状况。通过一组复杂的算法，AUMA执行器不断更新其维护日志，准备在任何参数达到定义的触发点时发出警报。

 

　　这些复杂的功能并不局限于高端执行器。例如，AUMA SAV、SA和SQ执行器都是AUMA资产管理的标准配置，***的条件是执行器配备了AUMA的电子控制单元。

 

　　Electric actuators are mainly composed of motors, bearings, gear drives and circuit controllers. Its fault mostly appears in the motor and bearing, and the gear drive part. The transmission part of electric actuator is inseparable from grease. Check lubrication during routine maintenance. Grease with stolen goods or leakage should be replaced and added.

 

　　hree kinds of maintenance

 

　　Traditionally, there are three types or levels of maintenance: reactive maintenance or the "fix it when it's broken" approach, which is actually a legitimate way to deal with relatively low-cost equipment with a low failure rate and relatively small failure consequences. The next level is preventative maintenance, which provides us with a rigorous process of regularly maintaining equipment, replacing oil, grease, filters and seals, and cleaning everything. The advent of small, reliable sensors and ways of communicating with central systems gives us the best way to maintain critical components today -- predictive maintenance, where there are no prescribed service intervals, but the device itself tells us when maintenance is needed and ensures that it continues to do its job reliably and efficiently.

 

　　Preventive maintenance

 

　　There are many considerations for electric actuators -- seals, grease, reversible contactors, and mechanical parts, and the preventive maintenance required within the system is determined by the combination of data recording and sensor measurements. Obviously, each actuator will run at a slightly different load, and we can record the number of starts, the number of revolutions of the shaft, the time the device has been running, and the output speed, all of which can predict when the commutator contactor and actuator mechanical structure will need maintenance. We cannot directly measure the condition of the grease, but we can measure the vibration, temperature and torque of each point in the actuator, and get the condition of the machine from it. Through a complex set of algorithms, the AUMA actuator constantly updates its maintenance logs, ready to sound an alarm when any parameter reaches a defined trigger point.

 

　　These complex functions are not limited to high-end actuators. For example, AUMA SAV, SA, and SQ actuators have come standard with AUMA asset management, the only condition being that the actuators are equipped with AUMA's electronic control unit.
