چکیده

The article presents a construction, static testing and modelling of a single flapper nozzle pneumatic valve. Authors show testing of piezo tube PT230 which distinguishing feature is deflection in two directions. This testing is preliminary work in design of a novel electropneumatic valve. Studies have been performed on a special designed bench which consists of a pneumatic valve, which used piezo tube as a flapper. Data acquisition process and control were performed by dSPACE system. The preformed static pressure control tests, confirmed applicability of tube actuator in flapper nozzle type valves. Obtained results were compared with simulation model prepared in Matlab Simulink software. Streszczenie. Artykuł zawiera opis konstrukcji, badania statyczne i modelowanie zaworu typu dysza przysłona. Autorzy zaprezentowali badania piezo rurki model PT230, której cechą charakterystyczną jest możliwość odkształcenia w dwóch kierunkach. Praca ta jest przygotowaniem do konstrukcji nowego zaworu elektropneumatycznego. Badania zostały wykonane na specjalnie w tym celu wykonanym stanowisku zawierającym zawór, którym zastosowano piezo rurkę jako przysłonę. Procesy akwizycji danych oraz sterowania wykonane zostały w systemie dSPACE. Przeprowadzone badania statyczne sterowania ciśnieniem wyjściowym, potwierdzają możliwość zastosowania piezo rurki w zaworach typu dysza przysłona. Zarejestrowane wyniki poddano porównaniu z modelem przygotowanym w oprogramowaniu Matlab Simulink. (Zawór pneumatyczny typu dysza przysłona z rurką piezoelektryczną jako elementem zadającym)

Design and Simulation of Valve Less PZT Micropump for Drug Delivery System

In this paper some discrete parts of an electrostatic and flat-walled self-aligned valveless, micropump for drug delivery system is designed and simulated. The core component of the system is a piezoelectric diaphragm that can convert the reciprocating movement of a diaphragm actuated by a piezoelectric actuator into a pumping effect. The deflection in the diaphragm was analyzed by applying the...

Design and Fabrication of an Array Microejector Driven by a Shear-Mode Piezoelectric Actuator

This paper reports a novel actuating design that uses the shear deformation of a piezoelectric actuator to deflect a bulge-diaphragm for driving an array microdroplet ejector. In essence, we employed a circular-shaped actuator poled radial direction with remnant polarization normal to the actuating electric field for inducing the piezoelectric shear effect. The array microdroplet ejector consis...
