浩博是一家專業銷售ROS-2D拉姆齊跑偏開關的廠家,主要產品有:防偏開關、拉線開關等煤炭、冶金、化工、糧食為國內多家企業配套生產咨詢電話:18853736667 R0S-2D防偏開關可固定在輸送機縱梁的頂部或底部，動作臂距皮帶邊緣大約25到75mm。通常安裝在皮帶兩側距頭部或尾部滾筒0.3到2米的地方。 皮帶跑偏后，迫使動作臂偏離，觸動DPDT報警微動開關。如果繼續偏停到停機觸點，觸動另一組觸點，輸送機就會保護性停機。 設備描述 　通用的安裝設計可使防偏開關隨意安裝在輸送機縱梁頂部或底部 　堅固的鑄鋁外殼，防護標準NEMA4，特殊的環境可選特殊的表面處理 　整體式蓋板易于接線及調整 　不需拆除動作桿就可拆掉蓋板 　動作桿軸承額定轉速5000轉/分，適合于皮帶速度小于6.35米/秒 　動作桿法向角調節范圍為22.5° 　法向夾角為10°時報警觸點動作，法向夾角為20°時停機觸點動作 應用范圍 　常規皮帶輸送機 　地下、索道支撐皮帶輸送機 　輪船裝卸系統 　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 Ramsey（原“美國拉姆齊”） 皮帶機拉線防護器 Thermo Fisher Scientific offers a variety of components for monitoring conveyors and other bulk material handling equipment, including the Ramsey Pro-Line Safety Cable Pull Switch. These devices monitor operating processes for potentially hazardous conditions and activate an alarm when they occur. This helps to keep your personnel safe, your equipment from being damaged, your time from being wasted, and your profits from becoming losses. For Emergency or Normal Shut-Off A safety pull cable is attached to the actuating arm of the Ramsey Safety Cable Pull Switch and terminated at fixed mounts at either end of a conveyor. Force applied to the pull cable at any position causes the actuating arm to move into a tripped-locked position and activates an alarm from one DPDT or two SPDT micro-switches, alerting equipment circuits of the stop condition. This will stay locked until manually reset by the reset lever.
