METHOD FOR ASSEMBLY AND REPAIRS OF SECTIONALIZED CYLINDRICAL PIEZOCERAMIC TRANSDUCER Russian patent published in 2001 - IPC

FIELD: manufacture and repairs of sonar equipment for hydroacoustic inspections. SUBSTANCE: method for assembling cylindrical piezoceramic transducer from piezoids in the form of prisms involves transducer forming, winding of glass thread with binder onto its external side surface at certain tension, and transducer bonding at side surfaces by means of adhesive compound at the same time polymerizing adhesive compound and binder. Upon winding glass thread and before polymerizing the binder adhesive seams between prisms are filled with liquid-phase adhesive compound admitted from inner space of transducer under pressure built up due to thread tension. Upon filling adhesive seams adhesive compound is removed from inner space of transducer. EFFECT: facilitated procedure, reduced labor consumption, improved quality of adhesion. 2 dwg
