在设计负载反馈液压系统时，必须确保反馈信号的准确性，否则，会直接影响对执行机构的控制。文章分析了管路液阻对反馈信号的影响。指出，如系统中存在较长管路，就不宜采用泵控负载反馈系统。
When designing a load feedback hydraulic system, the accuracy of the feedback signal must be ensured or it will directly affect the control of the actuator. The paper analyzes the influence of pipeline liquid resistance on the feedback signal. Pointed out that if the system has a long pipeline, it is not appropriate to use pump-controlled load feedback system.
