防水跑偏開關DPK-20-35防水跑偏開關DPK-20-35防水跑偏開關DPK-20-35

用于常規(guī)皮帶輸送機：地下、索道支撐皮帶輸送機：輪船裝卸系統(tǒng)；堆垛/取料輸送機；傾斜和梭式輸送機；起重機、挖掘機，起重臂限位：裙邊給料機/輸送機：重型極限開關檢測膠帶的跑偏量，是實現(xiàn)膠帶機控制的自動報警和停機的保護裝置。廣泛用于冶金、煤炭、水泥建材、采礦、電力、港埠、冶金、化工等領域的各種帶式輸送設備。

跑偏開關起帶式輸送現(xiàn)場的保護作用，因此必須達到的IP防護等級。
開關分兩個位置檢測輸送機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，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。此開關安裝方便，運行可靠，是帶式輸送機*的保護裝置之一。
 基本原理　　輸送機在運行中，當皮帶跑偏且與開關立輥接觸時，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)不停機狀態(tài)下的跑偏自動調(diào)整。二級開關信號用于停機，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。當故障排除后，膠帶離開立輥正常運轉(zhuǎn)時，立輥可自動復位。
