简介:摘要:随着煤炭行业生产自动化程度的提高,计量技术也越来越受到重视。然而,传统的计量方式容易受到外界环境的影响,使用误差大且维护量高。为了提高计量精度和稳定性,图像复核双校验计量系统应运而生。本文主要探讨了图像复核双校验计量系统在枣泉洗煤厂现场应用的效果。首先介绍了该系统的概念、组成及工作流程,接着分析了该系统在现场应用的效果。随后提出了在枣泉洗煤厂现场应用需要继续优化的地方。最后,结论指出该系统的应用效果显著,具有良好的推广应用前景。
简介:本文叙述了检测感应电机笼型转子中断条的技术。一台30马力带有深导条笼型转子的四极感应电机是从加拿大通用电气公司获得的。安装了用于试验目的的定子磁轭,齿尖与外探查线圈,以及热电偶。将轴转矩传感器与直流负载电机安装成一条直线。用有限元来模拟该电机的横截面,并用非线性多元的稳态技术来计算场分布及机械性能。断条的出现产生局部的高气隙磁场并降低了机械性能。磁场的波动与断条有关,通过机械加工有意地使其与端环分开,波动的磁场在探查线圈感应的电压中产生低频分量与谐波并产生振荡力矩,而它又引起噪声与机械振动。实验结果表明对外探查线圈中感应的电压的分析足以检测断条的存在与否。
