Experimental Simulation of Piston Leakage in an Axial Piston Pump

Fluid Power Systems and Technology, 2005
A method used to introduce “artificial leakage” into an axial piston pump to simulate leakage from a worn piston is described in this paper. A pressure control servo valve with a very high frequency response was employed to divert flow from the pump outlet in a prescribed waveform directly to tank.

The Cavitation Issue in Asymmetrical Axial-Piston Pumps

Journal of Dynamic Systems, Measurement, and Control, 2022
Abstract Pump-controlled single-rod hydraulic actuators have long been the subject of intensive research toward building valve-less, more efficient systems. The main challenge is to deal with the uneven flows into and out of the differential cylinders.

The kinematic analysis of axial-piston pumps

Mechanism and Machine Theory, 1983
Abstract This investigation describes the kinematics of axial hydraulic pumps with spherical ended pistons. The results, however, apply to the basic kinematics of all axial piston pumps. The current hypothesis is that sliding at the piston/swash plate interface contributes to the wear of these parts.

Reduction of axial piston pump pressure ripple

Proceedings of the Institution of Mechanical Engineers, Part I: Journal of Systems and Control Engineering, 2000
The reduction in source flow ripple in hydraulic systems is the most effective method of reducing pump-generated pressure ripple and system noise. This paper describes reductions in axial-piston pump delivery flow ripple achieved using a novel timing mechanism which is inherently speed, flow and pressure sensing. Fixed-speed tests have shown that the

Modeling and Simulation on Light Axial Piston Pump

Applied Mechanics and Materials, 2010
Flow and pressure regulation axial piston pump is studied in this paper. Model of the pump is built in AMESIm, and then characteristics of flow rate and pressure are calculated and analyzed in this model. This provides a good platform to the design and research of axial piston pump.

Robust Design of Piston Assemblies in an Axial Piston Pump

International Journal of Fluid Power, 2014
The piston slipper in an axial piston pump demonstrates most complicated dynamic motions: two rotations (tilting toward to the swash plate and rotating about the pump shaft) and one translation together with the pumping piston. In addition, the slipper is used to lubricate the swash plate surface with hydraulic oil, but prevents high pressure fluid ...

Dynamic of an Axial Piston Pump With Floating Pistons

BATH/ASME 2024 Symposium on Fluid Power and Motion Control
Abstract A new structure of the axial piston pump was proposed to address the limitation of its application under low viscosity medium conditions due to the insufficient oil film bearing capacity. The piston of this structure is in a floating state in the axial direction, and both ends of the piston are supported by a discrete cylinder ...

Study of a Novel Axial Piston Pump with Adjustable Tilting Piston

2019 IEEE 8th International Conference on Fluid Power and Mechatronics (FPM), 2019
In pump-control system, the flow rate is controlled by the rotating rate of pump or the displacement of the pump. The fixed displacement axial piston pump is designed for the rated operating condition. Therefore, the volumetric efficiency becomes worse when the rotating rate becomes lower.

Thermal modeling of axial piston pump and application

2015 International Conference on Fluid Power and Mechatronics (FPM), 2015
This paper analyses energy conversion and heat transfer in axial piston pump. According to it, the thermal mathematical model of axial piston pump is built by control volume method. This model can make full use of the dimension parameters of pump. The validity of the model is verified by the simulation for hydraulic system with axial piston pump.

Analysis of KZB axial piston pump's self-cooling

2010 5th IEEE Conference on Industrial Electronics and Applications, 2010
This paper presents a totally new kind of pump, called KZB pump, which has highly efficiency in self-cooling. Compared with other type of pumps, it has a great advance in self-cooling. The conclusions have been proved by several industrial experimental results. KZB pump, made according to the principles of double-end with oil axial piston pump, and its
