跑偏开关PK1-2BW 厂家
产品概述
跑偏开关PK1-2BW是一种专为带式输送机设计的安全保护装置，用于实时检测输送带的跑偏情况。该产品采用两级动作设计，当输送带发生轻微偏移时触发一级报警信号，若偏移加剧则触发二级停机信号，有效防止物料溢出或设备损坏。其结构紧凑，安装便捷，适用于冶金、煤炭、电力、化工等多种工业场景。外壳采用高强度铝合金材质，表面经过静电喷涂处理，具备优异的防腐蚀和防水性能，可在恶劣环境下长期稳定工作。1612
Product Overview
The PK1-2BW belt deviation switch is a safety protection device specifically designed for belt conveyors, monitoring real-time belt misalignment. It features a two-stage action mechanism: the first stage triggers an alarm signal upon minor deviation, while the second stage initiates an emergency shutdown if the deviation worsens, effectively preventing material spillage or equipment damage. With a compact design and easy installation, it is widely used in industries such as metallurgy, coal mining, power generation, and chemical processing. The housing is made of high-strength aluminum alloy with electrostatic coating, offering exceptional corrosion resistance and waterproof performance for reliable operation in harsh environments. 255
核心功能
PK1-2BW通过立辊与输送带边缘接触实现检测功能。立辊与皮带间距可调（通常为50-100mm），当皮带偏移挤压立辊至一级角度（如12°）时输出报警信号；若偏移持续扩大至二级角度（如30°），则输出停机信号。产品支持自动复位，故障排除后立辊恢复初始状态。适用于常规皮带机、斗式提升机、港口装卸系统等设备，可集成到自动化控制系统实现跑偏自动调整。179
Key Features
The PK1-2BW utilizes a roller mechanism to detect belt edges. The adjustable roller spacing (typically 50-100mm) allows customization based on conveyor width. When the belt deviates and presses the roller to the first-stage angle (e.g., 12°), an alarm signal is activated; if deviation reaches the second-stage angle (e.g., 30°), a shutdown signal is sent. The device supports automatic reset after troubleshooting. Compatible with belt conveyors, bucket elevators, and port handling systems, it can be integrated into automated control systems for real-time deviation correction. 610
适用行业
该产品广泛应用于散料输送领域，如矿山中的原煤输送、水泥厂的原料传输、发电厂的燃料供应线等。其防尘密封设计和耐高低温特性（-40°C至60°C）使其适应极端工况，如露天矿区或高湿度环境。同时，在码头装卸系统和自动化仓储物流中也能发挥稳定保护作用。51121
Industry Applications
The device is widely applied in bulk material handling, including raw coal transportation in mines, raw material transfer in cement plants, and fuel supply lines in power stations. Its dust-proof sealing and temperature resilience (-40°C to 60°C) ensure performance in extreme conditions like open-pit mines or humid environments. It also provides reliable protection for port loading systems and automated warehouse logistics. 1220
设计与安装
产品采用模块化设计，立辊高度可调（位于皮带边缘下1/3处），安装支架可通过螺栓直接固定于输送机机架。建议每30-50米安装一对开关，头部、尾部及易跑偏段为重点布设区域。配套电缆接口支持快速接线，简化现场部署流程。11316
Design & Installation
The modular design includes an adjustable roller (positioned at the lower 1/3 of the belt edge) and bolt-on mounting brackets for direct attachment to conveyor frames. Recommended installation interval is 30-50 meters per pair, with emphasis on head/tail sections and known deviation-prone areas. Pre-wired cable interfaces simplify on-site deployment. 722

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。
