Annular magnetic ultrasonic transducer applicable to pipeline installation

Abstract

The invention discloses a magnetic ultrasonic transducer applicable to pipeline installation. The transducer is composed of a magnetostrictor, a magnet exciting coil, energy conduction ring pieces, an electrical protective shell and installation accessories. The magnetostrictor is welded to the energy conduction ring pieces. The magnet exciting coil is wound around the magnetostrictor. The energy conduction ring pieces are designed to be in an arc shape. The energy conduction ring pieces are connected through the installation accessories and then form an energy conduction ring to be matched with pipelines of different pipe diameters. The magnet exciting coil is connected with an external ultrasonic controller through a lead. During working, the magnet exciting coil is controlled by the ultrasonic controller to generate a high-frequency alternating magnetic field. Due to the fact that the magnetostrictor can generate flexible deformation generated under the action of the alternating magnetic field, mechanical vibration is generated. Magnet exciting vibration can work at the ultrasonic frequency, vibration is transmitted to the pipelines or media inside the pipelines through the energy conduction ring, the ultrasonic effect is generated, and therefore the functions of scale prevention, scale removal and cleaning of the pipelines are achieved.

Description

technical field [0001] The invention belongs to the technical field of transducers, and in particular relates to a ring-shaped magneto-ultrasonic transducer suitable for pipeline installation. Background technique [0002] Carbonate deposits (hereinafter referred to as scale) are usually formed during the operation of heat exchange equipment and pipelines. The deposition of these scales reduces the flow area, reduces the heat transfer coefficient, greatly increases the energy consumption of the equipment, and reduces the energy consumption of the equipment. performance, and increased investment in equipment maintenance. [0003] In recent years, with people's emphasis on energy and environmental protection, more and more companies have paid attention to the problem of equipment scaling, and have invested in equipment transformation to prevent or slow down equipment scaling and descaling. Many different technologies have also appeared on the market. way products. Ultrasonic...
