2、混凝土输送缸在分配阀的控制下,交替地将混凝土吸入和排出。HBT60 混凝土 输送泵的分配阀为 S 形管阀,它的一端与输送管接通,另一端则通过摆动与两个混凝土输 送缸交替接通,对准哪一个缸口,哪一个缸就向外排出混凝土。同时,另一个缸则从料斗 中吸入混凝土。S 管阀的摆动是通过对称配置于 S 管阀回转轴两侧的液压缸推力臂来实现 的。 关键词关键词 混凝土输送泵;液压缸;S 管阀;分配阀 II Abstract The HBT60 concrete delivery pump will be one kind conforms to the transportation condition conc
