动力设备的附件包括各式水冷却器、热交换器,在循环冷却中有结垢现象。新装的冷却器热交换效果很好,均达到设计要求,但运行长时间后,管子慢慢结垢,孔径越来越小,冷却效果越来越不好,久而久之,如不及时采取措施,就能完全堵死,设备不能正常运转,影响生产,严重时还会造成事故。 我厂的制氧设备中的5L—16/50型空压机和2D-12/100型空压机冷却器芯子均是铁管的,设备运转约二年（4000台时）就结垢堵死,过去采取用手电钻接长钻头清理,效果不好,有时钻不通时,钻头还断在管子里,实无办法就报废更新一台新的芯子,目前每台新
Power equipment accessories include all kinds of water coolers, heat exchangers, fouling in the circulating cooling. The newly installed cooler heat exchange effect is very good, have reached the design requirements, but running a long time, the tube slowly fouling, pore size getting smaller and smaller, the cooling effect is getting worse, as time passes, if not timely measures Can be completely blocked, the device can not operate normally, affecting production, serious accidents will result. Oxygen plant in our factory 5L-16/50 air compressor and 2D-12/100 air compressor cooler core are iron pipe, the device is running for about two years (4000 units) on the scale Blocking the past to take a long drill with a flashlight to clean up the drill, the effect is not good, and sometimes drilling is unreasonable, the drill also broken in the pipe, there is no way to scrap a new core update, each new
