堵煤开关，HQKDS-1628AGLAC220VÄ不锈钢
产品概述
HQKDS-1628AGLAC220VÄ不锈钢堵煤开关是一款专为工业物料输送系统设计的检测设备，采用304不锈钢材质制造，具有优异的耐腐蚀性和耐磨性。该产品主要用于检测输煤皮带、溜槽或料仓中的物料堵塞情况，当物料堆积达到设定位置时，开关可快速触发报警或停机信号，有效防止因堵煤导致的设备损坏或生产中断。其结构设计紧凑，适用于高温、粉尘等恶劣工业环境，是电力、冶金、水泥、港口等行业的关键保护装置。136
技术特点
该堵煤开关采用微电机驱动检测叶片旋转的工作原理，当物料阻碍叶片转动时，内部机构会触发双刀双掷继电器输出信号（DPDT），响应时间仅20毫秒。产品支持AC220V电源输入，环境温度适应范围-40℃~60℃，最大电缆长度可达45米。特的全封闭油封设计能有效防止粉尘渗入，延长设备使用寿命。安装时需避开物流直接冲击方向，通常嵌装于落煤斗仓壁或溜槽侧壁，建议与入料口保持1米以上水平距离以确保检测准确性。214
功能优势
HQKDS-1628AGLAC220V具备抗干扰性强、信号稳定的特点，其检测结果不受物料湿度或温度变化影响。高耐磨的316L不锈钢探杆和叶片设计可抵抗酸碱腐蚀，特别适合燃煤输送场景。产品支持常开/常闭形式切换，可通过弹簧自动复位，故障排除后无需人工干预即可恢复待机状态。此外，射频防护功能使其在强电磁干扰环境下仍能可靠工作，静电火花防护设计则提升了易燃环境中的安全性。61214
应用场景
本产品广泛应用于火力发电厂输煤系统、矿山输送带、水泥厂原料仓等场景。在皮带输送机系统中，可安装于溜槽三分之二高度处作为重度堵塞检测点，或与振动电机联动实现轻度堵塞自动振打功能。其模块化设计允许传感器与变送器分离安装，便于高空作业维护。典型应用包括：检测给煤机落煤管堵塞、预防煤仓高料位溢出、监控港口卸料系统物料流通状态等。2614
Product Overview
The HQKDS-1628AGLAC220VÄ stainless steel coal blockage switch is a detection device specifically designed for industrial material conveying systems. Constructed from 304 stainless steel, it offers exceptional corrosion and wear resistance. This product primarily monitors material blockages in coal conveyor belts, chutes or silos, triggering instant alarms or shutdown signals when accumulated materials reach preset positions, effectively preventing equipment damage or production interruptions caused by coal jams. Its compact structure suits harsh industrial environments with high temperatures and dust, serving as a critical protection device in power plants, metallurgy, cement plants and ports.13
Technical Features
Operating on a micro-motor driven rotating vane principle, this switch activates DPDT relay output within 20ms when material obstructs the vane. It supports AC220V power input with an operational temperature range of -40℃~60℃ and maximum cable length of 45m. The fully enclosed oil-sealed design effectively prevents dust ingress, extending service life. Installation requires avoiding direct material flow impact, typically embedding in coal hopper walls or chute sidewalls, with recommended 1m horizontal clearance from feed inlets for detection accuracy.214
Functional Advantages
The HQKDS-1628AGLAC220V delivers stable anti-interference performance unaffected by material humidity or temperature fluctuations. Its 316L stainless steel probe and vane resist acid/alkali corrosion, ideal for coal handling. Configurable as normally open/closed with spring auto-reset function, it requires no manual intervention post-fault clearance. RF shielding ensures reliability under electromagnetic interference while electrostatic spark protection enhances safety in combustible environments.612
Applications
Widely deployed in coal-fired power plants, mining conveyors and cement raw material silos, this device can be installed at two-thirds height of chutes for severe blockage detection or synchronized with vibrators for mild clogging self-cleaning. Modular design allows separate sensor/transmitter mounting for easier high-altitude maintenance. Typical uses include: monitoring feeder pipe blockages, preventing silo overflows, and tracking material flow in port unloading systems.2614
