The PH12-30 belt misalignment switch is a protective device for belt conveyors and other transmission equipment. It monitors belt deviation and sends alarm or shutdown signals to prevent equipment damage or material spillage caused by misalignment. Featuring a durable aluminum alloy casing with high strength and lightweight design, it operates reliably in temperatures ranging from -20℃ to 85℃. With rated voltage of 220V/380V and current of 10A, its two-stage activation (12° for alarm and 30° for shutdown) makes it suitable for mining, power, and chemical industries. 6
產(chǎn)品結(jié)構(gòu)與工作原理
該產(chǎn)品通過(guò)立輥與輸送帶邊緣接觸來(lái)檢測(cè)跑偏情況。當(dāng)皮帶發(fā)生偏移時(shí),立輥受到擠壓產(chǎn)生偏轉(zhuǎn),當(dāng)偏轉(zhuǎn)角度達(dá)到12°時(shí)觸發(fā)第一組觸點(diǎn)發(fā)出報(bào)警信號(hào);若偏移繼續(xù)加大至30°,則第二組觸點(diǎn)動(dòng)作實(shí)現(xiàn)自動(dòng)停機(jī)。產(chǎn)品內(nèi)部采用雙微動(dòng)開(kāi)關(guān)結(jié)構(gòu),動(dòng)作靈敏可靠,復(fù)位方式為自動(dòng)復(fù)位,操作力約5-7kg。安裝時(shí)需將立輥軸線與輸送帶平面垂直,距離皮帶邊緣50-100mm,通常每30-50米安裝一對(duì)。5
The device detects misalignment via a roller contacting the belt edge. When the belt deviates, the roller tilts - triggering the first contact at 12° for warning and the second at 30° for shutdown. Its dual micro-switch mechanism ensures responsive operation with automatic reset function and 5-7kg actuation force. During installation, the roller axis should be perpendicular to the belt surface with 50-100mm edge clearance, typically installed every 30-50 meters along the conveyor. 16

3.跑偏開(kāi)關(guān)數(shù)量應(yīng)根據(jù)輸送機(jī)長(zhǎng)度、類型及布置情況進(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。
