摘要
介绍了气力输送中变径管道的设计方法和主要参数(临界速度、管径、压降、气体流速、变径位置、变杆角)的确定。通过分析实验数据,说明采用逐渐增大管径的变径管道可以有效地降低输送管道中的气速、压损和能耗。
This paper discusses design of stepped pipe of pneumatic conveying system and determination of main parameters such as critical speed, pipe diameter, pressure loss, air flow speed, pipe diameter changing position and stepped pipe angle. Experimental datas show that using stepped pipe can reduce effectively air flow speed, pressure loss and energy loss.
