PPN-12-30防水防爆跑偏開關(guān)PPN-12-30防水防爆跑偏開關(guān)PPN-12-30防水防爆跑偏開關(guān)
基本原理
當(dāng)輸送帶運行中出現(xiàn)跑偏時,輸送帶觸碰開關(guān)立輥并使立輥偏轉(zhuǎn),當(dāng)立輥偏轉(zhuǎn)角度達(dá)到1級開關(guān)角度時,開關(guān)發(fā)出報警信號。當(dāng)輸送帶跑偏嚴(yán)重,達(dá)到2級開關(guān)角度時,開關(guān)發(fā)出停機信號,實現(xiàn)輸送帶跑偏故障自動停機。當(dāng)跑偏故障排除后,膠帶機正常運轉(zhuǎn)時,開關(guān)立輥可自動復(fù)位,回到初始狀態(tài)。
安裝和調(diào)整
1.跑偏開關(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.跑偏開關(guān)立輥與輸送帶正常位置的間距宜為50~100mm。
3.跑偏開關(guān)數(shù)量應(yīng)根據(jù)輸送機長度、類型及布置情況進(jìn)行確定。一般應(yīng)在輸送機頭部、尾部、凸弧段、凹弧段和在輸送機中間位置進(jìn)行設(shè)置。(注:當(dāng)輸送機較長時,在輸送機中間位置可每隔30~35米設(shè)1對)
4.跑偏開關(guān)應(yīng)通過安裝支架與輸送機中間架連接,開關(guān)支架應(yīng)在輸送機安裝完成后與輸送機機架焊接,跑偏開關(guān)與跑偏開關(guān)支架用螺栓固定。
跑偏開關(guān)的分類
跑偏開關(guān)有普通型的、接線腔型、地址編碼的。
普通型的就是以上所說兩級跑偏開關(guān);
接線腔型跑偏開關(guān)是在普通型跑偏開關(guān)的基礎(chǔ)上自帶一個防水接線腔,現(xiàn)場控制電纜可直接接入接線腔,杜絕電纜接頭受潮、虛連造成的故障。
地址編碼型跑偏開關(guān)是在普通跑偏開關(guān)的基礎(chǔ)上融合了XLline現(xiàn)場總線技術(shù),實現(xiàn)了地址編碼功能。適用于較長帶式輸送機作為遠(yuǎn)程監(jiān)測現(xiàn)場設(shè)備的運行情況,解決了工人尋找故障點所帶來的不便。
地址編碼型兩級跑偏開關(guān)與綜合保護(hù)儀(網(wǎng)關(guān))通過XLline現(xiàn)場總線方式連接,zui大支持128個地址,且同一地址可多個開關(guān)同時使用,其zui大特點是只需一條兩芯電纜即可同時完成數(shù)據(jù)傳輸且無需電源供電。
XLline現(xiàn)場總線zui終可實現(xiàn)與各大廠家PLC和計算機接口靈活鏈接。
