2 避免励磁回路开路
直流电念头在启动或工作时,励磁回路一定要接通,不能让它断开(启动时要将励磁电流调到年夜)。否则,由于磁路只有很小的剩磁,就可能发生下列事故:(1)电念头是静止的,由于转矩太小,它将不能启动,这时候反电动势为零,电枢电流很年夜,电枢绕组有被烧坏的危险;(2)若是电念头在有载运行时断开励磁电路,反电动势立即减小而使电枢电流增年夜,同时由于所发生的转矩不能知足负载的需要,电念头势必减速而停转,加倍促使电枢电流的增年夜,以致烧毁电枢绕组和换向器;(3)若是电念头空载运行,它的转速可能上升到很高(这类事故称为飞车),使电念头蒙受严重的机械损伤,而且因电枢电流过年夜而将绕组烧坏。是以切记:在使用电念头时,若是要改变直流电念头的转动标的目的,必需改变电磁转矩的标的目的;经常或实时检查电枢电路中的串接启动电阻,随时更换串接电阻,避免该电阻阻值发生变化,出格是阻值减

减速机是一种相对精密的机械,使用它的目的是降低转速,增加转矩?
速比=电机输出转数÷减速机输出转数("速比"也称"传动比")
1.知道电机功率和速比及使用系数,求减速机扭矩如下公式:减速机扭矩=9550×电机功率÷电机功率输入转数×速比×使用系数
2.知道扭矩和减速机输出转数及使用系数,求减速机所需配电机功率如下公式:电机功率=扭矩÷9550×电机功率输入转数÷速比÷使用系数
它的种类繁多,型号各异,不同种类有不同的用途。减速器的种类繁多,按照传动类型可分为齿轮减速机、蜗杆减速机和行星齿轮减速机;按照传动级数不同可分为单级和多级减速机;按照齿轮形状可分为圆柱齿轮减速机、圆锥齿轮减速机和圆锥-圆柱齿轮减速机;按照传动的布置形式又可分为展开式、分流式和同轴式减速机。

为了使电镀的废水达到排放标准,人们不但从废水处理的方法上进行了大量的研究,而且从镀液本身和镀后的漂洗方式上都进行了改革。在电镀工艺上,开展了对无氰电镀、低铬电镀和无铬钝化、低铬酸镀铬、三价铬镀铬或代铬镀层、代镉镀层等工艺的研究和探索,并取得了较大的进展。如无氰镀锌、低铬钝化、低铬酸镀铬等工艺已在全国范围内得到不同程度的推广使用,大幅度地降低了全国电镀工业对、铬酐的使用量。这些新工艺的投产,从根本上消除或减少了剧毒的和铬酸盐对环境的污染。
