An Overview of Unveiling the Essence of Digital Hydraulic Technology: A Comprehensive Exploration and Classification

Abstract

Abstract The advent of digital hydraulic technology has heralded noteworthy advancements across a spectrum of domains, encompassing aspects such as intelligence augmentation, seamless integration, and the imperative curtailment of energy consumption, among other facets. Over the course of several decades, the continued investment in research and development has culminated in a substantial surge of interest and attention in the industrial and scientific communities. However, the varying interpretations and elucidations of digital fluid technology put forth by diverse researchers throughout the years have yielded a conspicuous absence of a universally endorsed and accepted definition. This definitional diversity has, to a certain extent, engendered ramifications on the trajectory of its evolution. Consequently, the present paper undertakes the task of furnishing a precise and comprehensive explication of digital hydraulic technology. In doing so, we deliberate upon several salient facets, including an in-depth exploration of digital hydraulic technology, a systematic classification thereof, an exhaustive examination of digital hydraulic valves, and a comprehensive analysis of digital hydraulic pumps.
