跑偏开关PH12-30 价格
PH12-30跑偏开关产品介绍(中英双语)
PH12-30跑偏开关是一种用于带式输送机等传动设备的保护装置,主要用于检测皮带跑偏情况并及时发出报警或停机信号,从而避免因跑偏造成的设备损坏或物料洒落。该产品采用铝合金压铸壳体,具有强度高、重量轻的特点,外壳防护等级良好,可在-20℃至85℃的环境温度下稳定工作。其额定电压为220V/380V,额定电流10A,动作角度分为两级(一级12°报警,二级30°停机),适用于矿山、电力、化工等行业的输送系统。1
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
产品结构与工作原理
该产品通过立辊与输送带边缘接触来检测跑偏情况。当皮带发生偏移时,立辊受到挤压产生偏转,当偏转角度达到12°时触发第一组触点发出报警信号;若偏移继续加大至30°,则第二组触点动作实现自动停机。产品内部采用双微动开关结构,动作灵敏可靠,复位方式为自动复位,操作力约5-7kg。安装时需将立辊轴线与输送带平面垂直,距离皮带边缘50-100mm,通常每30-50米安装一对。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
产品特点与适用场景
该跑偏开关具有结构简单实用、性能稳定的特点,能适应粉尘、震动等工业环境。铸铝外壳经过防腐蚀处理,防护性能良好。产品可提供红色等多种外观选择,适用于胶带机、刮板机、提升机等多种传动机械的跑偏保护,在电厂、钢厂、水泥厂等场合均有应用。根据不同需求,还可选择带LED指示灯等附加功能型号。614

工作原理
跑偏开关固定在输送机皮带支架上,动作杆靠在皮带一侧,当皮带跑偏时,迫使动作杆偏离,触动报警微动开关。如果继续偏离,触动另一组触点,输送机就会保护性停机。
主要技术数据
输出触点:两组SPDT,10A/500V;
动作角度:第10度,第二级20度;
作用力:3-4kg;
动作杆距皮带边缘安装距离:25-75mm;
出线接口螺纹:3/4″NPT,两个;
防护等级:IP65,适合室外安装。
跑偏开关(Belt Sway Switches)又称防偏开关,也叫两级跑偏开关。用于检测带式输送机运行中的跑偏现象,按皮带实际跑偏量输出报警或停机信号,可有效的防止由皮带跑偏而产生的事故,是一种带式输送机的保护装置。
安装和调整
1.跑偏开关设在输送带两侧,立辊应与输送带边平面垂直,并使输送带两边位于立辊高度1/3处。
2.跑偏开关立辊与输送带正常位置的间距宜为50~100mm。
3.跑偏开关数量应根据输送机长度、类型及布置情况进行确定。一般应在输送机头部、尾部、凸弧段、凹弧段和在输送机中间位置进行设置。(注:当输送机较长时,在输送机中间位置可每隔30~35米设1对)
4.跑偏开关应通过安装支架与输送机中间架连接,开关支架应在输送机安装完成后与输送机机架焊接,跑偏开关与跑偏开关支架用螺栓固定。
适用范围
两级跑偏开关广泛用于冶金、煤炭、水泥建材、采矿、电力、港埠、冶金、化工等域的各种带式输送设备。
