兩級(jí)跑偏開(kāi)關(guān)PPKG-12-30兩級(jí)跑偏開(kāi)關(guān)PPKG-12-30兩級(jí)跑偏開(kāi)關(guān)PPKG-12-30

跑偏開(kāi)關(guān)具有兩級(jí)動(dòng)作功能。一級(jí)動(dòng)作用于報(bào)警，二級(jí)動(dòng)作用于自動(dòng)停機(jī)。膠帶機(jī)在運(yùn)行中，當(dāng)膠帶跑偏且與本開(kāi)關(guān)立輥接觸時(shí)，立輥?zhàn)赞D(zhuǎn)，若跑偏量繼續(xù)加大，則擠壓立輥發(fā)生偏移。 
　　當(dāng)立輥偏轉(zhuǎn)角度超過(guò)12°時(shí)，一級(jí)開(kāi)關(guān)動(dòng)作，輸出（報(bào)警信號(hào)）。
　　當(dāng)立輥偏轉(zhuǎn)角度超過(guò)30°時(shí)，二級(jí)開(kāi)關(guān)動(dòng)作，輸出（停機(jī)信號(hào)）。
一級(jí)開(kāi)關(guān)信號(hào)用于報(bào)警，如果將此信號(hào)與跑調(diào)整裝置相接，即可實(shí)現(xiàn)不停機(jī)狀態(tài)下的跑偏自動(dòng)調(diào)整。 
二級(jí)開(kāi)關(guān)信號(hào)用于停機(jī)，將此信號(hào)接至控制線路中，即可實(shí)現(xiàn)重度跑偏狀態(tài)下的自動(dòng)停機(jī)。
當(dāng)故障排除后，膠帶離開(kāi)立輥正常運(yùn)轉(zhuǎn)時(shí)，立輥可自動(dòng)復(fù)位。
