润滑油是大型旋转设备重要的冷却润滑介质,对设备的安全运行有着重要意义,对冷却介质的监控也有着同等重要的意义,而流量开关就起着这样的作用。流量开关的选择、安装和调试是影响流量监控的重要环节。由于金川集团选矿厂热导式流量开关不能满足运行要求,故对其改造更换为机械挡板式流量开关,效果良好。在此进行分析与总结,强调自动化元件与现场环境相结合的重要性,也分析了两种流量开关的原理及优缺点。
Lubricating oil is an important cooling lubricant for large rotating equipment, which is of great importance to the safe operation of the equipment. It is equally important to monitor the cooling medium, and the flow switch plays a role. Flow switch selection, installation and commissioning is an important part of traffic monitoring. As the Jinchuan Group thermal conductivity flow switch can not meet the operational requirements, so the transformation of its replacement for the mechanical baffle-type flow switch, the effect is good. In this analysis and summary, emphasizing the importance of the combination of automation components and the scene environment, also analyzed the principle of the two flow switch and advantages and disadvantages.
