防水兩級(jí)跑偏開(kāi)關(guān)JPKJ-S型防水兩級(jí)跑偏開(kāi)關(guān)JPKJ-S型防水兩級(jí)跑偏開(kāi)關(guān)JPKJ-S型

基本原理

當(dāng)輸送帶運(yùn)行中出現(xiàn)跑偏時(shí)，輸送帶觸碰開(kāi)關(guān)立輥并使立輥偏轉(zhuǎn)，當(dāng)立輥偏轉(zhuǎn)角度達(dá)到1級(jí)開(kāi)關(guān)角度時(shí)，開(kāi)關(guān)發(fā)出報(bào)警信號(hào)。當(dāng)輸送帶跑偏嚴(yán)重，達(dá)到2級(jí)開(kāi)關(guān)角度時(shí)，開(kāi)關(guān)發(fā)出停機(jī)信號(hào)，實(shí)現(xiàn)輸送帶跑偏故障自動(dòng)停機(jī)。當(dāng)跑偏故障排除后，膠帶機(jī)正常運(yùn)轉(zhuǎn)時(shí)，開(kāi)關(guān)立輥可自動(dòng)復(fù)位，回到初始狀態(tài)。

安裝和調(diào)整

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。

3.跑偏開(kāi)關(guān)數(shù)量應(yīng)根據(jù)輸送機(jī)長(zhǎng)度、類(lèi)型及布置情況進(jìn)行確定。一般應(yīng)在輸送機(jī)頭部、尾部、凸弧段、凹弧段和在輸送機(jī)中間位置進(jìn)行設(shè)置。（注：當(dāng)輸送機(jī)較長(zhǎng)時(shí)，在輸送機(jī)中間位置可每隔30～35米設(shè)1對(duì)）

4.跑偏開(kāi)關(guān)應(yīng)通過(guò)安裝支架與輸送機(jī)中間架連接，開(kāi)關(guān)支架應(yīng)在輸送機(jī)安裝完成后與輸送機(jī)機(jī)架焊接，跑偏開(kāi)關(guān)與跑偏開(kāi)關(guān)支架用螺栓固定。
