Експериментальні дослідження статичних робочих процесів електрогідравлічного перетворювача нормально-закритого типу

Abstract

The aim of this study is to obtain the workflow static characteristics of an normally closed electrohydraulic converter with a design scheme is proposed by the author. To accomplish the goal of this prototype converter has been tested on the bench, with further statistical data processing. As a result, the dependences of the pressure and flow of the current administration. Found an experimental confirmation of the hypothesis underlying the creation of an electrohydraulic converter, the possibility of working together electropilots check valve and a nozzle-flapper element installed in series. Dependence of the pressure converter from the current administration is almost linear. This opens the possibility of using electro-hydraulic converter proposed by the author in the proportional hydraulics and for direct control by hydraulic engines of small capacity.
