APPARATUS FOR EVALUATING ULTRASONIC CAVITATION EROSION BY DATA ACQUISITION

摘要

The invention relates to an apparatus for evaluating ultrasonic cavitation erosion which may be used in order to evaluate the resistance of materials to cavitational attack as a consequence of the effects of ultrasonic frequency vibrations. According to the invention, the apparatus consists of an ultrasound generator (GU) with software system for correlating frequency and amplitude, a mechanical resonator assembly (AR) consisting of the following components: a piezoceramic converter (1), an amplitude transformer (2), a conical sonotrode (3), a specimen (4) for testing erosion by cavitation and a reaction vessel (VS), the assembly formed this way being functionally coupled with a Peltier-type thermostated cooling system (SR) connected to a data acquisition system with a programmable automaton, an operating system (SOP), a monitor (MO), a viewing system (SV) of the HD NETWorking type, a sound meter (SO), an infrared temperature sensor (SIT), a pH analyzer, a system (SF) for filtering the reaction liquid and a system (SI) for lighting in visible spectrum.
