Abstract

The service life of axial piston pumps, renowned for their high power-to-weight ratio and durability, can be compromised by wear, leading to safety risks and costly maintenance. This study investigates the factors that reduce service life, focusing on adhesive wear in the barrel-valve plate contact pair. A dynamic model based on the finite element method (FEM) is developed to predict wear using Archard's theory, while a computational fluid dynamics (CFD) model evaluates internal pressure distribution. The analysis shows that differential pressure causes the barrel to tilt toward the valve plate, accelerating wear. Through the design of experiments (DOE) techniques, the impact of critical operational parameters - discharge pressure and rotational speed - is quantified, revealing their significant influence on wear rates. Low pressure and speed increase wear, emphasizing careful management of these conditions. Additionally, load fluctuations accelerate wear, underscoring the importance of maintaining consistent operating conditions. Understanding these factors can help extend the service life of axial piston pumps, improve safety, and reduce maintenance costs.
