型鑄鋁兩級(jí)跑偏開關(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)跑偏開關(guān)的第二組觸點(diǎn)動(dòng)作,可使輸送機(jī)自動(dòng)停車。
