FIELD: oil and gas extractive industry. ^ SUBSTANCE: device has set of coaxially placed piezoceramic converters, connected to each other through mounting parts and fixed together by centering rod, pressurizing elastic cover with two end lids, filled with electro-isolating liquid. Each piezoceramic converter has shape of correct straight polyhedral prism, sides of which are made in form of piezoceramic plates. Connection of piezoceramic plates to mounting part is made with possible realization by piezoceramic plates of resilient transverse oscillations. Inner volumes of piezoceramic converters and volume, formed by their outer surface and elastic cover, have hydrodynamic connection. ^ EFFECT: higher efficiency. ^ 3 cl, 8 dwg |
