NJGC耐压式称重给煤机
Model NJGC Pressure Coal-Weighing Feeder
 
产品概述
NJGC耐压式称重给煤机适用于火力发电厂燃煤锅炉制粉系统,能在很大的负荷变动范围内改善锅炉性能,使过热温度、再熟温度和压力温度的控制更为稳定,使燃料所需空气更为匹配,所需的空气过剩量减少,连续给煤、称量准确、工作稳定、节能高效,是燃煤锅炉制粉系统中与磨煤机相匹配的先进的计量给煤设备。
Model NJGC Pressure Coal-Weighing Feeder app'icalbe for the milling system of the power plant.and it will highly enhance the boiler perfromance within a la rger load changing range. so that the over-heated.Hot temperature and pressure of the temperature control is more stable, and the needed air is more match the fuel, the excess amount of air will be reducedThe whole system is an avdanced weighing feeder device that match the coal crusher of the coal-firad boiler milling system for its hIgh product performance.high weighing accuracy.
工作原理
储煤仓中的煤通过煤闸门进入给煤机,由给煤机内部的输送计量胶带连续均匀的输送磨煤机中,在输送计晕胶带的下面装有电子称重装置,该装置主要由高精度电子皮带秤组成,称重传感器产生一个与煤的重量成比例的电信号和速度传感器检测到的皮带速度信号,同时送人积算器,经积算后得到瞬时流量和累计量。
结构特点
圆筒形密封结构,提高耐压力,减少内部粉尘堆积;
采用性能卓越的ST2、ST4系列电子皮带秤,确保计量准确和长期稳定;
变频(或滑差)无级调速、运行平稳,节能降耗;
链条刮板清扫装置自动清扫机内的积尘和余煤;
完善的报警系统可及时发现和排除堵煤、断煤过载和皮带跑偏等故障;
配置的高温隔离闸门,可防止热风回流,安全性高,检修方便。
Structural features
Full-Sealed cylindrlcal structure. enhance the pressure-resistant. reduce the dust accumulation;Using superior performance ST searial belt scale. assuring high weighing accuracy and long-term stabiliW;
Frequency lor slipl stepless speed regulating, running Smooth, saving energy and reducing consumption;Chain scraper with automatic cleaning machine to clean the dust and coal:Sound alarm system to detect timely and remove the coal-block coal-off overload and fault belt deviation;Equipped high-temperature isolation gate. to prevent the return of hot air. safe and easy maintenance
