Damping on the swash plate of an axial-piston pump

Proceedings of the 2000 American Control Conference. ACC (IEEE Cat. No.00CH36334), 2000
An, open loop, reduced order model is proposed for the swash plate dynamics of an axial piston pump. The difference from previous reduced order models is the modeling of a damping mechanism not reported previously in the literature. An analytical expression for the damping mechanism is derived. The proposed reduced order model is validated by comparing

Slipper Balance in Axial Piston Pumps and Motors

Journal of Tribology, 1992
The paper presents the results of an experimental and theoretical investigation of the effect of clamping ratio and orifice size on the performance of slippers in axial piston pumps and motors. Polishing of the running face to a slightly convex form appears to be essential for successful operation under all conditions. It is shown that slippers operate

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 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.

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.
