摘要
以装载机典型工况重载提升为例,详细地分析了定量系统与负载敏感变量系统的能耗情况,得出在不同操作模式下,定量系统与变量系统在节能特性上有其各自的优势。并计算得出一个临界值,当重载提升时间低于临界值时,定量系统更加节能;高于临界值时,负载敏感变量系统的节能特性才能得到发挥。
By lifting boom with heavy load of wheel loader typical workingcondition as an example,a detailed analysis of the energyconsumptionof fixed pump displacement system and load sensing system,under different operating modes,fixed pump displacement system and load sensing system has its own advantage in energy saving features.A critical value is calculated,when the lifting time is lower than the critical value,the fixed pump displacement system is more energy saving;when the lifting time is more than the critical value,load sensing system energy saving features is played well.
