型鑄鋁兩級(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)(15°),,PNS-I型兩級(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°),,PNS-I型兩級(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,。
