        電動執行器如何辨別是否需要維修?

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

        電動執行器相對于氣缸來說對電動執行器生產廠家和使用廠家的環境和員工的技術水平要求都比較高。并且無論是普通型電動執行器還是進口電動執行器在平常使用的過程中難免會出現一些損壞,其中常見的就是電動閥門。不過電動閥門是否需要維修從表面上是不能夠區分出來的,這個時候應該要如何辨別呢?其實很簡單,在電動執行機構進行工作的時候,都會留下存儲記錄,這些被存儲下來的數據能夠檢測出電動閥門的狀態,并且提示電動執行器生產廠家和使用廠家是不是需要維修,具體需要維修哪里,下面我們就來具體了解一下。


           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.
            能夠辨別閥門電動執行器是否需要維修的數據主要7個,總結起來就是五個摩擦,一個動態力、一個位置。“五個摩擦"分別是閥座摩擦力、閥門運行過程的摩擦力、閥桿和閥門軸承的摩擦力矩、閥門填料或者密封摩擦力、以及.閥桿螺紋摩擦力;一個動態里是指的閥芯所受動態力;位置是指閥桿的位置。一般在閥門電動執行器沒有問題的時候,每次存儲的數據應該都是比較穩健的,但是如果是閥門出現了問題,那么這些數據的統計就會有比較大的區別,因此我們可以從力矩曲線上的變化來進行預測和辨別,看看是否閥門電動執行器出現了問題,是不是要進行維修了。
        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.


            如果閥門電動執行器出現了損壞,那么整個電動執行器生產廠家和使用廠家使用就會出現很多的問題,給工作帶來很多的麻煩,因此我們平常的時候一定要注意觀察一下存儲的數據,預測一下是否需要修理閥門。
           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.
