Analysis of multithreaded choke dividers and flow dividers-adders

Abstract

Hydraulic drives, which for the most part is multi-circuit and branched, are widely used in hydraulic drives of modern mobile equipment and technological equipment. The analysis of the conducted studies has shown that throttle flow dividers, as well as flow dividers-adders, are the most suitable for providing automatic control of multi-circuit systems. Dividers are used to separate one working fluid flow entering the divided into two independent streams with an arbitrary flow ratio independent of loads. If it is necessary to organize a larger number of threads, two-threaded DP and DSP are switched on sequentially, and then one additional thread divider must be installed to receive each subsequent stream. Thus, in order to obtain n threads, it is necessary to have (n-1) two-threaded thread dividers, which is quite expensive and technically unjustified. The article describes the designs of multithreaded choke dividers and flow dividers-adders and a comparative analysis of their basic properties is carried out.
