摘　　要：在负载反馈技术的基础上,结合固定流量控制回路和多路阀比例控制流量的液压原理,设计出一种可变控制压差的流量调节回路,并测试了其流量特性,提出相应的使用注意事项,可为多种载荷同时动作、流量变化大的流量控制系统的设计、使用和维护提供参考。On the basis of load feedback technology, combined with the hydraulic principle of fixed flow control cirucrit and multi-way valve proportional flow control,a flow adjustment circuit with variable control pressure difference was designed,and its flow characteristics were tested,and corresponding precautions were put forward. It can provide reference for the design,use and maintenance of the flow control system with multiple loads and large flow change.
