Influence of Piston Elastic Deformation and Structure Design on the Lubrication Characteristics of Piston Pair: Simulation Analysis

Lubricants
Piston pair is a key friction pair of the axial piston pump, but the influence of elastic deformation and the structure design method is not clear. To reveal the real performance of piston pair, a new fluid–solid coupling calculation method is proposed ...

A Spare Support Vector Machine Based Fault Detection Strategy on Key Lubricating Interfaces of Axial Piston Pumps

IEEE Access, 2019
Fault detection of axial piston pumps is of great significance to improve the reliability and life of fluid power systems. However, it is difficult to detect multiple faults on key lubricating interfaces due to the liquid-solid coupling.

RELIABILITY RESEARCH ON HYDRAULIC AXIAL PISTON PUMP

Proceedings of the JFPS International Symposium on Fluid Power, 1989
This paper describes the reliability of 25 SCY hydraulic axial piston pumps. On the basis of investigations, experiments and theoretical analyses, the pump failure mode and failure mechanism were found. The statistical study of test data was done, the failure distribution function and the distribution parameters were determined, and the pump life was ...

Novel Characteristics of Valveless Pumping [PDF]

, 2009
This study investigates the occurrence of valveless pumping in a fluidfilled system consisting of two open tanks connected by an elastic tube. We show that directional flow can be achieved by introducing a periodic pinching applied at an asymmetrical ...

Development of a Vibration-Based Health Monitoring Procedure using a Virtual Axial Piston Pump [PDF]

, 2015
Monitoring vibration signatures produced by axial piston pumps can provide insight into changes of the pump system, which may then be associated with early signs of mechanical or hydraulic component failures.

Research on the High Speed of Piston Pumps Based on Rapid Erecting of Launch Vehicles

Applied Sciences, 2023
Rapid erection is a key technology for modern warfare in vehicle weapon launch systems. It is challenging to attain rapidity with the hydraulic erecting system because of the intensified cavitation in the piston chamber at high speeds, which reduces ...

Permeability evolution during progressive development of deformation bands in porous sandstones [PDF]

, 2003
[1] Triaxial deformation experiments were carried out on large (0.1 m) diameter cores of a porous sandstone in order to investigate the evolution of bulk sample permeability as a function of axial strain and effective confining pressure.
