摘　　要：以日本川崎精机公司所提出的液压系统图为例将直驱式液压系统与传统液压系统进行比较,可明显看出直驱式液压系统的系统结构大为简化并节能。对构成直驱式系统的各部件进行了必要的说明,以期进一步对直驱式液压系统的理解。A specific comparison between direct drive hydraulic system and traditional hydraulic system was made taking the diagram of hydraulic system as an example provided by the Kawasaki Precision Machinery Company（Japan）. It is obviously that the system architecture of the direct-drive hydraulic system is greatly simplified and the system can reduce energy consumption. Some necessary explanations of the various components of the direct drive system was made, wishing have a further understanding of direct drive hydraulic system.
