摘要
管道刮板输送机运行阻力主要由散料重力及对管道的侧压力引起,经研究该侧压力呈曲线分布。分析散料重力压力及由重力压力引起的侧压力在管道的分布情况,得到侧压力计算简化公式,并导出了运行阻力计算公式,为管道刮板输送机的设计提供理论依据。
The running resistance of pipeline scraper conveyor is mainly caused by bulk material gravity and lateral pressure on the pipeline,which shows a curve distribution after research.In the paper,the distribution of bulk material gravity pressure and side pressure caused by gravity pressure in the pipeline is analyzed,a simplified formula for calculating side pressure is obtained,and a calculation formula for operating resistance is derived,providing a theoretical basis for the design of pipeline scraper conveyor.
