电动实行器如何辨别是否需要维修?

How to distinguish whether the valve electric actuators needs to repair or not?

电动实行器相对于气缸来说对电动实行器生产厂家和使用厂家的环境和员工的技术水平要求都比较高。并且无论是普通型电动实行器还是进口电动实行器在平常使用的过程中难免会出现一些损坏,其中常见的就是电动阀门。不过电动阀门是否需要维修从表面上是不能够区分出来的,这个时候应该要如何辨别呢?其实很简单,在电动实行机构进行工作的时候,都会留下存储记录,这些被存储下来的数据能够检测出电动阀门的状态,并且提示电动实行器生产厂家和使用厂家是不是需要维修,具体需要维修哪里,下面大家就来具体了解一下。

   Valve electric actuator has higher requirement for electric actuator manufacturer and manufacturer's environment and employees than the cylinder.And whether it is the ordinary type electric actuator or the imported electric actuator, it will inevitably cause some damage during the normal use process, the most common of damage is the electric valve.However, whether electric valves need to be repaired can not be distinguished from the surface. How should this be discerned?In fact,It's very simple. When the electric actuator works, it leaves a storage record. The stored data can detect the state of the electric valve and indicate whether the manufacturer and the manufacturer of the electric actuator need to repair it.Where is the specific need for maintenance? Let's have a detailed understanding below.
    能够辨别阀门电动实行器是否需要维修的数据主要7个,总结起来就是五个摩擦,一个动态力、一个位置。“五个摩擦"分别是阀座摩擦力、阀门运行过程的摩擦力、阀杆和阀门轴承的摩擦力矩、阀门填料或者密封摩擦力、以及.阀杆螺纹摩擦力;一个动态里是指的阀芯所受动态力;位置是指阀杆的位置。一般在阀门电动实行器没有问题的时候,每次存储的数据应该都是比较稳健的,但是如果是阀门出现了问题,那么这些数据的统计就会有比较大的区别,因此大家可以从力矩曲线上的变化来进行预测和辨别,看看是否阀门电动实行器出现了问题,是不是要进行维修了。
There are 7 main points that can distinguish whether the electric actuator needs to be repaired. It is concluded that there are five frictions, one dynamic force and one location.The "five frictions" are the seat friction force, the friction force of the valve operation, the friction torque of the valve stem and the valve bearing, the valve filling or the seal friction, and the friction force of the stem thread;A dynamic refers to the dynamic force of the spool, and the location is the location of the stem.When there is no problem in the valve actuators, the data stored each time should be more robust, but if there is a problem with the valve, the statistics of these data will be quite different.Therefore, we can predict and distinguish from changes in the torque curve to see whether the valve actuator has a problem and whether it needs to be repaired.

    如果阀门电动实行器出现了损坏,那么整个电动实行器生产厂家和使用厂家使用就会出现很多的问题,给工作带来很多的麻烦,因此大家平常的时候一定要注意观察一下存储的数据,预测一下是否需要修理阀门。
   If the valve electric actuator is damaged, then the entire electric actuator manufacturers and the use of the manufacturers will have a lot of problems and bring a lot of trouble to the work, so we must pay attention to the storage of data in ordinary times and predict whether the valve needs to be repaired.
