煤矿采煤生产中,工作面刮板输送机由于其工作条件恶劣,磨损严重,以致刮板输送机的使用寿命缩短,维修任务繁重,並常常出现由于链轮等部件的修复质量不能达到原设计要求,面不能保证使用一个生产周期,影响了采煤工作面的连续生产。提高刮板输送机的使用寿命和维修质量,是提高采煤生产效益很重要与迫切的问题。为解决上述问题,我们利用合金粉末喷焊工艺,对西德EKF—3/72V型刮板机的链轮齿面进行了喷焊修复,取得比较满意的效果。
Coal mining production, face scraper conveyor due to its poor working conditions, serious wear and tear, resulting in shorter scraper conveyor life, heavy maintenance tasks, and often appear due to the quality of repair parts such as sprockets can not reach the original design Requirements, surface can not guarantee the use of a production cycle, affecting the continuous production of coal mining face. Improve scraper conveyor life and maintenance of quality, is to improve coal production efficiency is very important and urgent problems. In order to solve the above problems, we use the alloy powder spray welding process to spray-repair the sprocket tooth surfaces of West Germany EKF-3 / 72V scraper to obtain satisfactory results.
