跑偏開(kāi)關(guān)XLPP-12-30跑偏開(kāi)關(guān)XLPP-12-30跑偏開(kāi)關(guān)XLPP-12-30

工作原理

兩級(jí)跑偏開(kāi)關(guān)安裝在皮帶輸送機(jī)兩側(cè)、距離皮帶機(jī)首尾端部1~3m的地方。當(dāng)皮帶跑偏時(shí)，皮帶邊緣壓向檔輪，迫使檔輪偏轉(zhuǎn)，使限位開(kāi)關(guān)動(dòng)作。為減少檔輪與皮帶的摩擦，檔輪的本體是由軸承制作的。

當(dāng)發(fā)生輕微跑偏事故時(shí)（12°），兩級(jí)跑偏開(kāi)關(guān)的*組觸點(diǎn)動(dòng)作，發(fā)出事故預(yù)告信號(hào)。

當(dāng)發(fā)生嚴(yán)重跑偏事故時(shí)（30°），兩級(jí)跑偏開(kāi)關(guān)的第二組觸點(diǎn)動(dòng)作，可使輸送機(jī)自動(dòng)停車(chē)。
