摘要
本文分析了当前断头吸棉风管中前后压差大的原因,并计算出管道摩擦阻力、局部阻力和前启动压差异各自占整个管道压差的百分比值,为改进断头吸棉的均匀度提出了方向;通过改变吸棉支管与吸棉干管的连接角的措施,改善断头吸棉管道前后吸气压力的差异,达到节能的目的。
The author puts forward the measure to improve the suction evenness by changing theconnection angle of the branch duct to main duct based on analysing the reason for pressuredifference between front, middle and back points of end-breakage suction duct on the ringframe, calculating the resistance force of the duct, partial resistance, and the differenceof front and back kneitic pressure, and evaluating the percentage of each to the whole pres-sure difference in the whole suction duct system. Consequently, the suction evenness is im-proved and the benefit of energy saving is obtained.
