As in all Hydraulic systems you need a pump, an actuator, and a resivior.
The actuator in this case will be a container that is filled with piezoelectric material and hydraulic fluid so that there is no air in the container once connected to the hydraulic system, forming a hydrostatic environment. The piezoelectric material is connected to a volt meter.
The pump is connected through a switching valve to both the container with the piezoelectrics and the resevior. There is of course a releif valve so that the pump does not burn out, or rupture a fluid line.
I'd like some thoughts on my little setup here. A main area of interest should be the volt meter attached to the piezoelectric material.
Please be more explicit in what you are trying to achieve. Your technical description is disjointed
>a container filled with piezo-electric material??
>Are you trying to produce a piezo voltage by
using alternate hi-low pressure from the oil pump?
Or as Uncle Al suggests, a small micro-pressure
in oil, by feeding a voltage to a piezo stack?
In either case the oil accumulator will even out your oil pump pressure. Resulting in no output from the piezo?? An accumulator normally allow you to switch off the oil pump until the pressure drops to below a preset point.
The Piezo (stack?) would require a fast alternating and vibrating pressure source thru the oil, to produce an AC voltage output. (Is that what your switching valve does?)
Or an AC voltage input to your piezo to produce a micro-AC-pressure in the oil.
Clarify your idea, or we cannot help further.
