BKLT2-II防爆雙向拉繩開(kāi)關(guān)接線(xiàn)圖

BKLT2-II防爆雙向拉繩開(kāi)關(guān)接線(xiàn)圖用金屬材料鑄造，有足夠的機(jī)械強(qiáng)度，抵抗井下工作時(shí)脫落的巖石、煤塊等物體的撞擊不被破壞，而開(kāi)關(guān)殼體上設(shè)置的隔爆面能夠的隔絕，殼體內(nèi)一旦發(fā)生時(shí)對(duì)殼體外井下的工作環(huán)境的影響。當(dāng)煤礦井下運(yùn)行的膠帶輸送機(jī)發(fā)生緊急事故時(shí)，啟動(dòng)隔爆型拉繩開(kāi)關(guān)，可立即停機(jī)警示，防止事故的擴(kuò)大，工作現(xiàn)場(chǎng)的人身，本開(kāi)關(guān)安裝使用方便，運(yùn)行可靠。
工作原理當(dāng)帶式輸送機(jī)現(xiàn)場(chǎng)發(fā)生緊急事故時(shí)，可拉動(dòng)系于開(kāi)關(guān)上的鋼絲繩，鋼絲繩帶動(dòng)擺臂旋轉(zhuǎn)而使開(kāi)關(guān)內(nèi)的行程開(kāi)關(guān)動(dòng)作，發(fā)生停機(jī)信號(hào)。防止事故的擴(kuò)大。
BKLT2隔爆型雙向拉繩開(kāi)關(guān)為手動(dòng)和自動(dòng)復(fù)位方式，在故障排除后，拉啟復(fù)位銷(xiāo)方能復(fù)位。
接線(xiàn)方式本機(jī)出廠(chǎng)時(shí)已配長(zhǎng)度為1.0米電纜線(xiàn)，接線(xiàn)方式參照標(biāo)牌所標(biāo)線(xiàn)色。
