混凝土泵车泵送混凝土时,若泵送缸换向冲击力过大,可产生以下5种危害:一是引起泵车臂架抖动,影响其使用寿命;二是使臂架末端软管摆幅增大,容易碰伤操作人员;三是容易引起主液压泵吸空,影响其使用寿命;四是使功率损失加大,燃油消耗量增加;五是使噪声增大,给环境带来不利影响。为此,笔者从液压系统及泵送缸两个方面研究降低泵送缸换向冲击力的措施。
Concrete pump truck pumping concrete, if the pump cylinder to the impact force is too large, can have the following five kinds of hazards: First, causing the jib pump jitter, affecting its service life; the second is to make the end of the boom hose swing Increase, easy to bruise the operator; Third, it is easy to cause the main hydraulic pump suction, affecting its service life; fourth is to make the power loss increases, fuel consumption increases; five is to make the noise increases, to the environment adversely affect . To this end, the author from the hydraulic system and pump cylinder to reduce the impact of two pumping cylinder to divert measures.
