皮带机拉姆齐保护装置

拉姆齐跑偏开关ROS-2D

添加时间:2016-04-29
拉姆齐跑偏开关ROS-2D

R0S-2D防偏开关可固定在输送机纵梁的顶部或底部,动作臂距皮带边缘大约25到75mm。通常安装在皮带两侧距头部或尾部滚筒0.3到2米的地方。 

皮带跑偏后,迫使动作臂偏离,触动DPDT报警微动开关。如果继续偏停到停机触点,触动另一组触点,输送机就会保护性停机。

设备描述 

 通用的安装设计可使防偏开关随意安装在输送机纵梁顶部或底部 

 坚固的铸铝外壳,防护标准NEMA4,特殊的环境可选特殊的表面处理 

 整体式盖板易于接线及调整 

 不需拆除动作杆就可拆掉盖板 

 动作杆轴承额定转速5000转/分,适合于皮带速度小于6.35米/秒 

 动作杆法向角调节范围为22.5° 

 法向夹角为10°时报警触点动作,法向夹角为20°时停机触点动作

Ramsey(原“美国拉姆齐”) 皮带机拉线防护器

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.

Options

Secondary flag alarm
