Engineering machinery control system and engineering machinery
The invention relates to an engineering machinery control system and engineering machinery. The engineering machinery control system is characterized in that a load-sensitive valve group is connected with a pump body and is used for adjusting the pressure and/or flow output by the pump body; the loading multi-way valve group is connected with the pump body and the load-sensitive valve group; the hydraulic output port is connected with the pump body and the hydraulic output port; the first switching valve group is arranged between the load-sensitive valve group and the loading multi-way valve group and between the load-sensitive valve group and the hydraulic output port, and is configured to selectively conduct an oil path between the load-sensitive valve group and the loading multi-way valve group or an oil path between the load-sensitive valve group and the hydraulic output port; and the processor is configured to enable the first switching valve group to conduct an oil path between the load-sensitive valve group and the loading multi-way valve group under loading operation and enable the first switching valve group to conduct an oil path between the load-sensitive valve group and the hydraulic output port under hydraulic output. According to the system, the output power and the output pressure of the pump body can be high under the condition of not influencing the uploading excavation operation.
本公开涉及一种工程机械控制系统及工程机械,工程机械控制系统包括:负载敏感阀组与泵体连接,调节泵体输出的压力和/或流量;上车多路阀组与泵体和负载敏感阀组连接;液压输出端口与泵体和液压输出端口连接;第一切换阀组设置于负载敏感阀组与上车多路阀组之间以及负载敏感阀组与液压输出端口之间,被配置为择一地使负载敏感阀组与上车多路阀组之间的油路或负载敏感阀组与液压输出端口之间的油路导通;处理器被配置为在上车作业下使第一切换阀组导通负载敏感阀组与上车多路阀组之间的油路,在液压输出下使第一切换阀组导通负载敏感阀组与液压输出端口之间的油路。该系统能在不影响上装挖掘作业的情况下使泵体输出功率大、输出压力大。
