《工程机械》2005年第9期刊载了《关于装载机双泵合流系统节能效果的分析》一文,阐述了配置双泵合流系统的装载机的工作原理。我们认为,这一问题应结合装载机的作业过程进行分析才能得出正确的结论。1装载机可完成的作业一般而言,装载机可完成的作业有:1)装卸作业;2)堆积作业;3 “Construction Machinery” No. 9, 2005, published “on the loader double-pump confluence of energy-saving effect analysis,” a paper describes the working principle of the loader with dual-pump confluence system. In our opinion, this problem should be analyzed in combination with the operation of the loader to arrive at the correct conclusion. 1 Loader can be completed operations In general, the loader can be completed operations are: 1) loading and unloading operations; 2) stacking operations; 3
