摘要:
A concrete agitating drum (1) is driven by a hydraulic motor (81). A connection switch-over valve (20) is arranged to have a function to regulate a flow cross-sectional area of pressurized working oil supplied to the hydraulic motor (81) from a variable capacity hydraulic pump (10). The variable capacity hydraulic pump (10) is driven by a combustion engine (60) together with a charge pump (11). When a discharge pressure of the charge pump (11) is low, the connection switch-over valve (20) maintains a small flow cross-sectional area to rotate the agitating drum (1) at a low rotation speed so that fuel consumption of the combustion engine (60) is suppressed to be small. When the discharge pressure of the charge pump (11) becomes high, the connection switch-over valve (20) enlarges the flow cross-sectional area, thereby realizing a rated rotation speed of the agitating drum (1).
摘要(中):
混合搅拌滚筒(1)由液压马达(81)驱动。 连接切换阀(20)被配置为具有调节从可变容量液压泵(10)供给到液压马达(81)的加压工作油的流动横截面积的功能。 可变容量液压泵(10)与电动泵(11)一起由内燃机(60)驱动。 当电荷泵(11)的排出压力低时,连接切换阀(20)保持小的流动横截面面积,以使转动鼓(1)以低转速旋转,从而使得燃料消耗 内燃机(60)被抑制得很小。 当电荷泵(11)的排出压力变高时,连接切换阀(20)扩大流动横截面积,从而实现搅拌滚筒(1)的额定转速。
