Description

一种混合动力挖掘机工作液组合物
技术领域
本发明一种混合动力挖掘机工作液组合物属于挖掘机液压系统润滑剂领域。
背景技术
混合动力技术被视为是当前工程机械最具应用价值的新能源技术之一。在液压挖掘机中，由于工作循环中负荷变大，使发动机功率没有被有效利用。因此大量能量被浪费掉，导致整车能耗较高。随着混合动力技术被逐步应用于液压挖掘机，通过混合动力技术回收工作在不同机体或工作装置动作时浪费的能量，并储存使之成为新的动力来源并加以应用，对发动机功率波动起到削峰填谷作用。这项新技术对降低发动机功率需求的同时，也能有效改善发动机运行工况，并起到明显的节能效果。
通常，传统意义上的液压挖掘机在工作时，转台的减速和制动能，以及升臂、斗料和挖斗的下降能都会以能量消耗的形式浪费掉。理论上，这些动作过程中的功能和势能都可以回收并加以利用。差异在于不同动作过程中具有的工作特点及可回收能量大小有所不同。如何寻求较合理的方式来回收，即在付出尽可能小的代价时，回收尽量多的能量。
液压混合动力技术源于液压蓄能器进行能量回收和利用，要解决蓄能器与多缸间的动臂势能增压交互回收利用，流量自动匹配的回转能量回收，能量回收和作业性能协同优化控制等技术困难。其能明显改善蓄能器与多缸间的动臂势能增压交互回收利用，流量自动匹配的回转能量回收，能量回收和作业性能协同优化控制等技术困难。
目前液压挖掘机主要以回收回转能量为主。回转液压马达的特性与电机有一定相似，能量转换可逆，电能也可以储存。特别是采用液压储能形式来回收回转能，这只需要在液压系统中，设置一套液压马达和发电机，用以回收力臂下降的能量，并将其转回电能储存。工作液正是这套系统的工作介质，工作温度：-50～150℃，工作压强：﹤30MPa。
