微量进给液压传动的基本要求是保证油缸进给的稳定性。这种进给稳定性与下列多种因素有关,即负荷的变化特性,各个液压元件的制造质量以及油液过滤程度等。本文中列出的四种液压系统都能提高油缸进给的稳定性。图1的微量进给液压传动(苏联发明证书568756)消除了停止进给时流量阀处于静止全开状态的
The basic requirement of the micro-feed hydraulic drive is to ensure the stability of the cylinder feed. This feed stability and a variety of factors related to the load characteristics of the change, the quality of the manufacture of various hydraulic components and the extent of fluid filtration and so on. The four hydraulic systems listed in this article improve the stability of the cylinder feed. The trace feed hydraulic drive in Figure 1 (Soviet Certificate of Invention 568756) eliminates the need for the flow valve to be at rest and fully open at stop feeding
