HJ換向器檢測裝置

換向器是有刷直流電機的關(guān)鍵部件之一，其質(zhì)量優(yōu)劣將直接影響人身和電機的運行。

隨著我國經(jīng)濟不斷發(fā)展，對外貿(mào)易擴大，電機產(chǎn)品出口的需要，上海南洋電機制造企業(yè)，為了合歐洲有關(guān)（地區(qū)）的檢測規(guī)定，09年委托我公司研發(fā)我國臺直流電機換向器檢測裝置，此裝置的研制成功改變了我國換向器人工逐片檢測、記錄的低工效落后狀況，填補了我國換向器檢測裝置的空白。

1、 換向器檢測裝置主要由以下10個主要部件組成：

（1）  換向器自動檢測裝置工作臺；

（2）  變頻齒輪減速電動機及傳動裝置；

（3）  脈沖編碼器；

（4）  換向器（受檢品）及檢測工裝（軸芯，套筒，填塊）；

（5）  測量兩電左右間距調(diào)節(jié)支架及調(diào)節(jié)旋柄；

（6）  測量電上下間距調(diào)節(jié)支架及調(diào)節(jié)旋柄；

（7）  電安裝臂；

（8）  電；

（9）  接觸式位移傳感器及磁性支座；

（10） 換向器檢測裝置控制柜，包括聲光報警器，顯示屏，工控機，耐電壓試驗儀，控制按鈕及指示燈，變頻電源等。

2、 現(xiàn)裝置檢測換向器外形尺寸范圍如下：

（1）  換向器外徑：ø150mm~ø600mm

（2）  換向器軸孔內(nèi)徑：ø60mm~ø140mm

（3）  換向器片數(shù)：50片~300片

（4）  換向器片的寬度：3mm~10mm

（5）  換向器片長度：70mm~400mm

（6）  換向器質(zhì)量≈300kg

3、主要技術(shù)參數(shù)

 （1）換向器片間耐電壓試驗

a、檢測電壓220~500VAC可調(diào)；

b、逐片對相鄰2片相互間及其對地的緣試驗；

c、檢測時換向器可按設(shè)定的速度能自行旋轉(zhuǎn)進(jìn)行檢測；

d、每片檢測時間：按工藝要求設(shè)定；

e、每片檢測點接觸1點，當(dāng)換向器片的長度較長時可另協(xié)議；

f、當(dāng)檢測時，如出現(xiàn)電氣短路缺陷時，裝置即發(fā)出聲、光報警，自動記錄該片片號、復(fù)位、并開啟高壓，繼續(xù)檢測。

（2）換向器片與片之間位移數(shù)值和外表面的徑向圓跳動的檢測

a、檢測換向器速試驗前后冷態(tài)時，片與片之間的位移數(shù)值和外表面徑向圓跳動數(shù)值，檢測數(shù)值為變化的值；

b、接觸式位移傳感器測量值的分辨率2微米；

c、檢測時換向器可按工藝要求設(shè)定的速度自行旋轉(zhuǎn)進(jìn)行檢測；。

4、數(shù)據(jù)處理：

  本檢測裝置分換向器圓度檢測和耐電壓試驗，并能對軸芯誤差進(jìn)行自動補償。測量過程中，實時顯示圓度誤差曲線和每一片數(shù)據(jù)；顯示耐電壓試驗短路電片位置。

檢測完成后，即生成徑向圓跳動數(shù)據(jù)表和曲線圖。

耐電壓試驗完畢，生成短路電片位置圖及數(shù)據(jù)。
