Cavitation in an Axial Piston Pump
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 ...

Wear prediction of piston/cylinder pair in axial piston pump
The piston/cylinder pair is the key lubricating interface of axial piston pumps. It suffers from excessive wear due to the huge lateral force, especially under high output pressure. In order to achieve predictive maintenance, it is significant to detect the performance degradation of the piston/cylinder pair. In this paper, a method to predict the wear
