摘　　要：简明分析了多功能破碎清塞机的液压系统。对3种方案(双定量泵节流系统,定量泵恒流量控制系统,变量泵负载敏感控制系统)的液压系统原理作了详尽的理论分析,并说明了多功能破碎清塞机选用变量泵负载敏感控制系统的理由。The paper presents briefly the hydraulic system of multi-functional crusher cleaner, makes detailed theoretical analysis of the mechanism of three hydraulic system plans （ throttle-governor system with fixed displaeement dual pump, constant flux control system with fixed displacement pump and load-sensitive control system with variable pump）, and describes the reasons for selecting the load-sensitive variable pump control system for multi-functional crusher cleaner.

关 键 词：节流调速 恒流量控制 负载敏感控制
