Modeling of a fast plate type hydraulic check valve
Sprache des Titels:
Check valve dynamics plays an important role in many
fluid systems, like in compressors, hydraulic pumps, and hydraulic
switching converters. Plate type check valves are a
frequently employed valve type in dynamically challenging
cases. Despite the relevancy of plate valve dynamics, few
exhaustive work can be found in literature, focusing on the
behavior of hydraulic check valves for high frequency applications.
This paper presents an in-depth characterization of
a plate valve designed as rectifier of a High Frequency Oscillation
Pump working at 300 Hz. The aim is to identify
a sufficiently simple mathematical model, which permits to
optimize the design of the valve for the considered application.
The paper analyzes the different phenomena contributing
to the dynamics of such a valve, and presents the results
of simulation and experimental activity. The results show
how small details in the design and manufacturing of those
valves (namely the contact surfaces) have important consequences
on the dynamics of the pump system. In general, a
good agreement between model and reality is achieved.
