mechanical transducer meaning in Chinese

机械转换器

This paper analyses the type , function and characteristics of usual proportional control valves and raises a new modificative version in the light of their drawback . that is , basing on the principle of flow amplification and electrical feedback and throughout calculation and analysis on flow closed loop control and pressure flow combination . , determination of the minimum controlled pressure difference as well as flow controlling range and structure of main valve and research of the dynamic and static characteristic , the paper puts forward control principle of " flow - load pressure change - displacement revision " and pressure / flow double closed loop , and further expounds that using a proportional controller and a electric mechanical transducer can separately serve the control function of pressure or flow as well as flow pressure combination
本论文分析了目前常用比例阀的类型、功能、特性，并针对其不足提出新的改进方案，即：以流量放大，电反馈两个原理为基础，通过对流量闭环控制及压力流量复合的计算分析、确定上最小控制压差及流量控制范围，确定主阀结构、功能特性研究等，提出了“流量? ?负载压力变化? ?位移修正”的控制原理和压力流量双闭环控制原理，并进一步论述了利用一个比例控制器和一个“电?机械转换器”就可完成独立的压力或流量控制功能以及流量压力复合控制功能。
