Abstract

Search for Effective Energy-Saving Methods in Hydraulic Drives of Mobile Machines through the Analysis of Experimental Test Results of Hydraulic Distributors and Motors.
The study focuses on identifying effective energy-saving solutions in positive displacement hydraulic drives of mobile machines by analyzing experimental data on power losses caused by pressure drops and fluid leakage in hydraulic distributors and motors. Additionally, the study includes a comparison of methods for regulating the displacement volume in axial piston hydraulic machines and high-torque radial piston multi-cycle hydraulic motors.
The research object comprises hydraulic components, particularly hydraulic distributors and motors. Dependencies between pressure drop and flow rate in both distributors and motors, as well as fluid leakage and mechanical power losses, are analyzed based on various displacement regulation methods when comparing axial piston machines to radial piston multi-cycle hydraulic motors.
A comparative analysis was conducted on motor displacement regulation methods, including a power regulation method without altering the phase angle of fluid distribution to the pistons, and a phase-based method involving a variable number of pressurized pistons.
The study addresses the need to provide engineers and master's students with a clear understanding of how modern hydraulic component design features affect power losses and contribute to improved energy efficiency in positive displacement hydraulic drives.
Based on the analysis, explanations are provided for the observed reduction in power losses in hydraulic distributors and machines. The results highlight the promising potential of phase-based regulation methods in axial piston hydraulic machines.
The research findings are considered valuable for professionals engaged in the development of advanced hydraulic components, as well as for master's students studying subjects related to the design, development, and testing of hydraulic and pneumatic systems.
