PWB-12-30跑偏開關(guān)PWB-12-30跑偏開關(guān)PWB-12-30跑偏開關(guān)

基本原理　

　 輸送機(jī)在運行中，當(dāng)皮帶跑偏且與開關(guān)立輥接觸時，立輥自轉(zhuǎn)，若跑偏量繼續(xù)加大，則擠壓立輥發(fā)生偏移。一級開關(guān)信號用于報警，如果將此信號與跑調(diào)整裝置相接，即可實現(xiàn)不停機(jī)狀態(tài)下的跑偏自動調(diào)整。二級開關(guān)信號用于停機(jī)，將此信號接至控制線路中，即可實現(xiàn)重度跑偏狀態(tài)下的自動停機(jī)。當(dāng)故障排除后，膠帶離開立輥正常運轉(zhuǎn)時，立輥可自動復(fù)位。

本開關(guān)的工作過程是輸送機(jī)膠帶跑偏時，膠帶觸碰開關(guān)立輥，當(dāng)立輥偏轉(zhuǎn)至Ⅰ級動作角度時，Ⅰ級開關(guān)動作，并輸出信號報警。如果膠帶繼續(xù)跑偏使開關(guān)的立輥達(dá)到Ⅱ級動作角度時，Ⅱ級開關(guān)發(fā)出停機(jī)信號。如果將其接至控制線路中即可實現(xiàn)自動停機(jī)。跑偏開關(guān)起帶式輸送現(xiàn)場的保護(hù)作用，因此必須達(dá)到的IP防護(hù)等級。
開關(guān)分兩個位置檢測輸送機(jī)皮帶的跑偏程度和扭曲程度。根據(jù)皮帶的跑偏程度和扭曲程度，實現(xiàn)自動報警和停機(jī)，避免昂貴的輸送皮帶受損壞及因皮帶扭曲造成的物料散落等事故。此開關(guān)安裝方便，運行可靠，是帶式輸送機(jī)*的保護(hù)裝置之一。
