適用范圍
兩級(jí)跑偏開(kāi)關(guān)用于常規(guī)皮帶輸送機(jī)：地下、索道支撐皮帶輸送機(jī)：輪船裝卸系統(tǒng)；堆垛/取料輸送機(jī)；傾斜和梭式輸送機(jī)；起重機(jī)、挖掘機(jī)，起重臂限位：裙邊給料機(jī)/輸送機(jī)：重型極限開(kāi)關(guān)檢測(cè)膠帶的跑偏量，是實(shí)現(xiàn)膠帶機(jī)控制的自動(dòng)報(bào)警和停機(jī)的保護(hù)裝置。廣泛用于冶金、煤炭、水泥建材、采礦、電力、港埠、冶金、化工等領(lǐng)域的各種帶式輸送設(shè)備。
使用環(huán)境條件：
1.環(huán)境溫度：-40℃~60℃
2.相對(duì)濕度不大于85%
3.海撥高度不超過(guò)2000m
4.使用壽命：開(kāi)關(guān)動(dòng)作10萬(wàn)次
5.絕緣電壓：AC1000試驗(yàn)1分鐘
6.觸點(diǎn)容量：≤AC380 ≤5A
1.跑偏開(kāi)關(guān)設(shè)在輸送帶兩側(cè)，立輥應(yīng)與輸送帶邊平面垂直，并使輸送帶兩邊位于立輥高度1/3處。
2.跑偏開(kāi)關(guān)立輥與輸送帶正常位置的間距宜為50～100mm。
