Cavitation in an Axial Piston Pump
Bulletin of JSME, 1983 In an axial piston pump made of acrylic resin, cavitation is observed by the naked eye with a strobo-scope and by high speed photography, and the pressure changes in the cylinder are measured. The cavitation is classified into the following two groups ; one, related to the trapping phenomenon, can be prevented by a suitable design of valve plates ...

Axial-piston pump optimal multivariable PID controller tunning
IOP Conference Series: Earth and Environmental Science, 2023 Abstract The aim of the present work is the synthesis and optimal tunning of a PID controller designed to control the displacement volume of an axial-piston pump intended for hydraulic systems with open circulation. The pump is controlled in real-time through a system developed by the authors based on an electro-hydraulic proportional ...

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
