電動(dong)執行器的(de)結構原理(li)

1、電(dian)動執行機構接收控制系統(tong)發出的開關信(xin)號后，電(dian)機不轉(zhuan)并有嗡嗡聲。其原因可能是：

1）電動(dong)執行(xing)機構減速器的行(xing)星齒輪部(bu)分卡澀、損壞或(huo)變(bian)形；

2）電動執(zhi)行機構減速器的斜齒(chi)輪傳動部分變(bian)形或過度磨損(sun)或損(sun)壞；

3）電動執(zhi)行機(ji)構減速器的渦輪渦桿或絲桿螺母傳(chuan)動部分(fen)變形損壞、卡澀等(deng)；

4）電動(dong)執行機(ji)(ji)構整體(ti)機(ji)(ji)械(xie)部分(fen)配合不(bu)好，不(bu)靈活，需調整加油。

2 電動執行器電氣部分故障結構原理

1）電(dian)(dian)(dian)動執(zhi)行(xing)機(ji)(ji)(ji)構(gou)接受控制(zhi)系統(tong)發出的(de)(de)開(kai)(kai)、關(guan)信號(hao)(hao)(hao)后，電(dian)(dian)(dian)機(ji)(ji)(ji)不轉，也無嗡嗡聲(sheng)。可(ke)能(neng)(neng)原因是(shi)：沒有交(jiao)流電(dian)(dian)(dian)源或電(dian)(dian)(dian)源不能(neng)(neng)加到電(dian)(dian)(dian)動執(zhi)行(xing)機(ji)(ji)(ji)構(gou)的(de)(de)電(dian)(dian)(dian)機(ji)(ji)(ji)部(bu)分或位置(zhi)定位器部(bu)分；PM放大板工作不正常，不能(neng)(neng)發出對(dui)應(ying)的(de)(de)控制(zhi)信號(hao)(hao)(hao)；固態繼電(dian)(dian)(dian)器部(bu)分損(sun)(sun)壞(huai)，不能(neng)(neng)將放大板送(song)來的(de)(de)弱(ruo)信號(hao)(hao)(hao)轉變(bian)成電(dian)(dian)(dian)機(ji)(ji)(ji)需要的(de)(de)強電(dian)(dian)(dian)信號(hao)(hao)(hao)；電(dian)(dian)(dian)機(ji)(ji)(ji)熱保(bao)護開(kai)(kai)關(guan)損(sun)(sun)壞(huai)；力矩限制(zhi)開(kai)(kai)關(guan)損(sun)(sun)壞(huai)；行(xing)程限制(zhi)開(kai)(kai)關(guan)損(sun)(sun)壞(huai)；手動/自動開(kai)(kai)關(guan)位置(zhi)選錯(cuo)或開(kai)(kai)關(guan)損(sun)(sun)壞(huai)；電(dian)(dian)(dian)機(ji)(ji)(ji)損(sun)(sun)壞(huai)。

2）電(dian)(dian)(dian)動執行機(ji)構接受控(kong)制(zhi)系統發出的開、關信號后，電(dian)(dian)(dian)機(ji)不轉，有嗡嗡聲(sheng)。其(qi)可能原(yuan)因是(shi)：電(dian)(dian)(dian)機(ji)的啟動電(dian)(dian)(dian)容損壞；電(dian)(dian)(dian)機(ji)線圈匝間輕微短路(lu)；電(dian)(dian)(dian)源電(dian)(dian)(dian)壓不夠(gou)。

3）電(dian)(dian)動(dong)執行機構接(jie)受控制系(xi)統發出(chu)(chu)的開、關(guan)信(xin)號(hao)后(hou)，電(dian)(dian)機抖動(dong)，并(bing)伴(ban)有咯(ge)咯(ge)聲，其(qi)原(yuan)因(yin)可(ke)能是：PM放(fang)大板的輸出(chu)(chu)信(xin)號(hao)不足(zu)不能使(shi)固態繼電(dian)(dian)器*導(dao)通，造(zao)成電(dian)(dian)機的加(jia)載(zai)電(dian)(dian)壓不足(zu)；固態繼電(dian)(dian)器性(xing)能變壞，造(zao)成其(qi)輸出(chu)(chu)端未*導(dao)通。
