Abstract

The present invention pertains to the field of geophysical well equipment and of equipment for applying physical actions on the fields. This invention can be used in geological prospecting, in the mining, petroleum- and gas-extraction industry as well as in other industrial branches for intensifying the extraction of mining resources. The piezoelectric converter includes a piezoelectric packet that comprises longitudinally polarised piezo-ceramic rings which are connected in parallel and associated with end parts having a thickness of μ\40, wherein μ is the wavelength of the material used for said parts. The piezoelectric converter also includes a reinforcement rod member as well as a retaining ring member that provides the longitudinal compression forces of the piezoelectric converter, i.e. the reinforcement force thereof. The retaining member comprises a flute for dampening oscillations and for eliminating the need for any reinforcement tube in the oscillating system. The piezoelectric packets are connected by a flexible insert or resilient member. The rod member and the retaining member are connected so that the reinforcement force can be adjusted. The resilient member and the end parts are made of a material exhibiting wave resistance as well as a thermal expansion coefficient for the ceramic of the rings, e.g. titanium or steel. This piezoelectric converter has an increased reliability and an extended life time.
