为了提高混凝土输送泵车自动化程度,确保设备的安全,防止料斗搅拌叶片工作时,被大骨料或其他硬物卡阻,料斗搅拌油路系统都应设计自动反转油路。如果设计不合理,会使系统频繁换向,不能正常工作。目前,大部分泵车都程度不同地存在这个问题。无论在使用,还是设计时,如不分析自动反转油路不稳定工作的原因,草率处理,系统的可靠性就会降低。
In order to increase the degree of automation of concrete pump trucks and ensure the safety of equipment, and prevent the hopper mixing blades from being blocked by large aggregates or other hard objects, the hopper mixing oil circuit system should be designed to automatically reverse the oil circuit. If the design is unreasonable, the system will frequently change direction and cannot work normally. At present, most pump trucks have this problem to varying degrees. Whether in use or design, if the cause of the inconsistent operation of the oil circuit is not analyzed, the reliability of the system will be reduced.
