ADVANCES IN THE SIMULATION OF AXIAL PISTON PUMPS
Proceedings of the JFPS International Symposium on Fluid Power, 2002 The present paper details advances attained in the modelling and simulation of axial piston pumps. The simulation environment is AMESim and new in-house developed submodels allow a quantitative appraisal of exchanged forces inside the pump. Care is devoted to the analysis and modelling of the port plate geometry that significantly contributes to the fl

Advanced Science, EarlyView.Heteroatom precursor engineering serves as a molecular‐level strategy to tailor hydrazide monomer reactivity and diffusion kinetics, enabling controlled assembly of highly crystalline COF membranes with ultramicroporous channels. The nitrogen‐enriched nanochannels deliver high water/ion selectivity via simultaneous water transport acceleration and ion ...

The importance of the knowledge of flow stream in water sump pump [PDF]
, 2013 Numerous different experimental and numerical methods have been developed and are already improved in order to get rather good flow descriptions inside pump components. These calculations are generally realized assuming uniform and steady flow conditions,

Liquified Natural Gas Pump With Hydrostatic Journal Bearings
, 1992 Lecturepg. 39In view of the inflammability of LNG (liquefied natural gas), submerged type pumps are normally used to protect against leaks. The overhaul interval of an LNG pump, therefore, is subject to the life of its ball bearings, because LNG is an ...

Evaluation of Tribological Property for Hydraulic Fluid by Roller on Disk Test
Tribology Online, 2015 The effects of energy-saving hydraulic fluids are confirmed by not only many actual hydraulic systems but also bench tests using hydraulic pump. We have studied some laboratory evaluation methods that are simpler than bench test using hydraulic pump.
