工作原理 两级跑偏开关NKPK1-12-30安装在皮带输送机两侧、距离皮带机首尾端部1~3m的地方。当皮带跑偏时,皮带边缘压向档轮,迫使档轮偏转,使限位开关动作。为减少档轮与皮带的摩擦,档轮的本体是由轴承制作的。 当发生轻微跑偏事故时(15°),DPP-K2/J型两级跑偏开关的*组触点动作,发出事故预告信号。 当发生严重跑偏事故时(30°),DPP-K2/J型两级跑偏开关的第二组触点动作,可使输送机自动停车。 特点 ·结构简单实用、性能稳定可靠 ·防尘、防震、防潮 ·体积小、重量轻、寿命长 ·安装方便,免维护 ·输出信号既可与现场设备联锁使用,也可送达微机控制系统 ·电源适应性广:24~380V(无源开关量) 跑偏开关NKPK1-12-30跑偏开关NKPK1-12-30跑偏开关NKPK1-12-30 技术参数 工作电压:24~380V 型号;NKPK1-12-30 绝缘电阻:>500MΩ 输出信号:无源开关量信号 环境温度:-20℃~+60℃ 环境湿度:<90% 重 量:2Kg 防护等级:IP65 复位方式:自动复位 响应时间:<2mS 控制触点容量:3-5A 动作力:50±10N HG-500K HG-1000K SC125x150,/SC125x150 HF-2 HF-5 /SC125x200 HF-10 HF-20 SC125x250,/SC125x250 HF-50 HF-100 HF-200 /SC125x300 HF-500/HF500 / SC125x350 /SC125x400 HF-1K N02 N07 HT5 ()HG-1K /SC100x500 /SC100x600 /SC100x700 HG-2K /SC100x800 /SC100x900 /SC100x1000 HG-5K HG-10K HG-20K HG-30K HG-50K HG-100K /SC125x50 /SC80x1000 HG-5 /SC100x50 HG-10 /SC100x100 /SC100x150 HG-20 /SC100x200 /SC100x250 /SC100x300 HG-100 /SC100x350 HG-500/HG500 /SC100x400 /SC100x450 N05 N05/90 /SC80x150 /SC80x200 NK-10 /SC80x250 NK-20 /SC80x300 /SC80x350 /SC80x400 NK-30 /SC80x450 NK-50/NK50 /SC80x500 NK-100 /SC80x600 NK-200 /SC80x700 NK-300 /SC80x800 NK-500 /SC80x900 /SC63x150 IRC-630 /SC63x300 /SC63x350 BDM-1 /SC63x400 NV-100c /SC63x500 NV-100D /SC63x600 /SC63x700 KD-5 /SC63x800 V-500-4 /SC63x900 /SC63x1000 V-830 /SC80x50 /SC80x100 V-810 XA-911 /SC50x600 XP-702ⅡZ XP-3110 /SC50x700 XP-3160 / SC50x800 XP-707Ⅱ /SC50x900 /SC50x1000 XA-370 /SC63x50 XP-707B /SC63x100 /SC63x200 XP-311A /SC63x250 XA-328id PS-6AH/PS-6NH PS-6/PS-6N /SC40x900 /SC40x1000 /SC50x50 SZMJ-302 SZMJ-102 /SC50x100 PSY-2 /SC50x150 SZGM-01 /SC50x200 /SC50x250 ()HEWK-01 /SC50x300 BZX-1H1 /SC50x350 XP-311A /SC50x400 XP-3140 /SC50x450 /SC50x500 /SC40x50 SZE-02 SZBS-1 基本原理 当输送带运行中出现跑偏时,输送带触碰开关立辊并使立辊偏转,当立辊偏转角度达到1级开关角度时,开关发出报警信号。当输送带跑偏严重,达到2级开关角度时,开关发出停机信号,实现输送带跑偏故障自动停机。当跑偏故障排除后,胶带机正常运转时,开关立辊可自动复位,回到初始状态。
