高频热处理工安全作业技术 | 2012-3-11 9:04:00

    1.必须要有两人以上方可操作高频设备,并指定操作负责人。操作时必须穿戴绝缘鞋和绝缘手套及其它规定的防护用品。并检查屏蔽和防护遮栏是否良好。工作时闲人免进。

    2.检查设备各部分按地是否可靠,淬火机床运行是否良好,机械、液压传动是否工作正常。

    3.开启水泵,检查各冷却水管是否出水正常,冷却水压在1.22个大气压之间,不准用手触及设备的冷却水。

    4.设备各部分冷却系统正常,方可给设备送电预热。先进行一档灯丝预热3045分钟后,再进行二档灯丝预热15分钟,之后合上半高压,再继续调移相器至高压。加高频后,手不许触及汇流捧和感应器。

    5.装好感应器,接通冷却水,将工件放入盛应器方可送电加热。严禁空载送电,更换工件,必须停止高频。若高频无法停止,应立即切断高压或连接紧急开关。

    6.设备运行中,注意阳流和栅流漉都不准超过规定值。

    7.工作时,全部机门必须关好.高压合上后,不得随意到机后活动,严禁打开机门。

    8.设备在工作过程中,发生异常现象时,应首先切断高压,再分析、排除故障。

    9.检修设备时,应预先声明。打开机门后,首先用放电棒对阳极、栅极、电容器等放电,然后再检修。严禁带电抢修、操作工不得独自检修设备。

    10.工作结束后,首先断开阳极电压,再断开灯丝电源。设备断电后,须继续供水1520分钟使电子管充分冷却。

    11.设备应保持清洁、干燥,不得有灰尘和潮湿现象,以防电气元件放电和击穿。

    12.室内应装有通风设备,排除淬火时发出的油烟、废气,保护环境。室内环境温度应控制在1535
