Measurement of Slipper Behavior in Swashplate-Type Axial Piston Pumps
In swash plate type axial piston pumps, slipper/swash plate sliding surfaces is subject to high fluctuating load. Therefore, the slippers are required to provide stable operation and reduce losses due to sliding. The behavior of the slipper fluctuates in

We developed a suppressed ion chromatography method with automated matrix neutralization and matrix elimination for the quantitative determination of ammonium in electrochemical ammonia synthesis research. Online determination of ammonium in 0.2 M sulfuric acid electrolyte revealed Nafion ionomer as a non‐negligible secondary source of ammonium ...

Axial piston pumps, new trends and development
International audience ; Efficiency improvement is a key issue in any machine. The fluid power industry relies on volumetric pumps which need to pump high pressure fluid to a set of actuators located at different positions in a given device; the higher the pressure, the smaller the actuators need to be, therefore allowing to reduce the weight of the ...

The Influence of Elevated Temperature on Time‐Dependent Compaction Creep in Bleursville Sandstone
Abstract The inelastic compaction of sandstone in the upper crust typically occurs at depths where temperatures range from approximately 50°C $50{}^{\circ}\mathrm{C}$ to 150°C $150{}^{\circ}\mathrm{C}$. Previous experimental studies have shown that even this modest temperature increase can reduce the yield stress required to initiate inelastic ...

Numerical Simulation Study on the Volumetric Efficiency Loss of CO2 Swash Plate Axial Piston Pumps
With the aim of addressing the low volumetric efficiency of CO2 swashplate axial piston pumps, the influence of four volumetric losses—loss of the CO2 compression retention volume, leakage volume loss of the port pair, leakage volume loss of the plunger ...
