Loads on the regulator of an axial-piston pump

Russian Engineering Research, 2010
A mathematical model is developed for the piston chamber of an axial-piston pump. On the basis of the model, the pressure within the chamber may be investigated in different operating conditions; the load at the regulator due to the pressure may be estimated; and the design of the pump and the regulator may be optimized.

Torque on the Swashplate of an Axial Piston Pump

Journal of Dynamic Systems, Measurement, and Control, 1985
As part of a study involving methods of control of an axial piston pump, it is required to obtain linear or linearized equations of motion of the system’s states. The torque imposed on the plate by the pumping action of the pistons is the most important term in the equation of motion of the swashplate.

Effect of piston clearance on the lubrication performance in axial piston pump

Industrial Lubrication and Tribology, 2019
Purpose This paper aims to provide a reliable and efficient numerical piston–cylinder design method and assess the effect of clearance on the piston-cylinder lubrication. Design/methodology/approach Numerical analyses of lubrication characteristics were performed for the piston–cylinder interface.

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.

Analysis and design of an axial piston water-pump with piston valve

Journal of Mechanical Science and Technology, 2011
In this paper, we present a novel axial piston water-pump with piston valve, which carries out the flow distribution to drain and sucks water by the interaction of each piston. This novel water-pump could achieve change in-phase between flow rate and the passage areas of the intake and outlet ports.

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 ...

Design and simulation of axial piston pump with constant flow

IEEE 10th International Conference on Industrial Informatics, 2012
There are flow pulsation in all existing piston pump, but this paper suggest a new constant flow method, and a axial piston pump with no flow pulsation in theory is designed. With the simulation in AMESim and MATLAB software, the dynamic characteristics of the new pump include pressure and flow are analyzed.

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.

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 ...

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.
