对原175型柴油机机体三面镗组合机床液压系统的改进

IMPROVEMENT ON HYDRAULIC SYSTEM OF 175 TYPE DIESELENGINE BORING MACHINE

本文介绍采用单电机双联泵控制多油缸动作如何进行防干扰问题，采用立体建模使液压站板块内部结构简单，直观性强，绘制生产图纸容易。改进后的组机节能、高效、维修方便。

This article introduces us to a theory about how a double pump and asingle dynarno control the movements of several pistons in order to privent disturbance,By using space models, the inner structure of the steel plate on a hydraulic box goes simple,and we can have a clear and direct visualization of it, So its production plan can be de-signed easily, The improved cominative machine-tool will economize on energy and workefficiently, The maintenance of it is also easy.
