摘　　要：连续运输系统由长距离分布的多套液压驱动设备组成,这些设备采用多组负载敏感比例多路阀,分别控制分散布置的各个液压执行机构(液压缸和液压马达)。多组负载敏感比例多路阀采用串联供油方式,由1台液压泵站供油。设计了一种新的负载敏感比例多路阀的连接块(进油联),使其更加适用于多组长距离分散布置负载敏感比例多路阀的串联连接,不但提高了执行机构的控制响应速度,还简化了液压系统的管路。The continuous transportation system consists of multiple sets of hydraulic driven equipment distributed over long distances,which use multiple sets of load sensitive proportional multi way valves to control the dispersed hydraulic actuators.Multiple sets of load sensitive proportional multi way valves adopt a series oil supply method,supplied by a hydraulic pump station.We have improved the design of a new connection block(inlet oil connection)for load sensitive proportional multi way valves,making it more suitable for series connection of load sensitive proportional multi way valves with multiple long distance dispersed arrangements.This not only improves the control response speed of the actuator,but also simplifies the pipeline of the hydraulic system.
