摘要
MG62—D型是第一台全部采用国产元部件的电牵引滚筒采煤机。该机的直流牵引部采用具有电流反馈和电压反馈的双闭环调速系统。本文较详细地分析了系统的工作原理和主要部件的特点,对了解和使用电牵引采煤机的调速系统有重要的实际意义。
The Type MG(?)2-D electric-traction drum shearer was the first one manufactured completely in home-produced parts. The d. c. traction portion of which comprises current and voltage feedback to form double closed-loop speed adjustment system. The paper analyses in detail the operating theory of the. system and the feature of the main parts. It will be helpful to those whoever make a good job of the system of the shearer.
