摘要
本文依据因次分析的基本原理,研究了装煤时旋叶升角的变化函数。根据最佳装煤条件下的试验数据,提出了合理旋叶升角的范围;并从截煤效率考虑,对此范围进行了修正。
The variable function of vane angle during loading is studied on the basic principle of dimensional analysis. A-reasonable range of vane angle is presented on the basis of experiment data in optimal loading condition, and the range is modified in view of cutting efficiency.
