Design of a piezoelectric liquid pump

AI Thread Summary
The discussion focuses on designing a piezoelectric liquid pump using RP printing and a PDMS diaphragm for mounting the piezo device. The designer seeks advice on strong, high-amplitude piezo materials and expresses concern about using medical check valves due to potential back pressure issues. Suggestions include considering a piezoelectric cleaner unit for diaphragm isolation and the need for a high-voltage circuit to drive the piezo device effectively. The conversation emphasizes the importance of material selection and flow control in the pump design. Input from those experienced with piezo materials and pump mechanisms is requested.

Hey guys

im in the process of designing a piezoelectric liquid pump, i am looking to make the structure out of RP printer for now and use a PDMS diagrphram for the piezo device to be mounted apon. Have any of you guys worked with piezo materials before as i am in need of a strong high amplitude varying one.

Also I am thinking of using medical check valves to be able to build a flow in one direction but i think there won't be enough back pressure to keep them tightly sealed.

Any opinions would help very much!

How about a piezoelectric cleaner unit to make the isolations to the diaphragm as this piezo devise is very strong but you would have to make a circuit to drive it at high voltage.
 

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'How can I find the cleanout for my building drain?'

I am a long distance truck driver, but I recently completed a plumbing program with Stratford Career Institute. In the chapter of my textbook Repairing DWV Systems, the author says that if there is a clog in the building drain, one can clear out the clog by using a snake augur or maybe some other type of tool into the cleanout for the building drain. The author said that the cleanout for the building drain is usually near the stack. I live in a duplex townhouse. Just out of curiosity, I...

Thread 'Dry sump pump issue'

I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
