Document Type and Number:
Japanese Patent JPH0681485
Kind Code:
B2
Abstract:
PURPOSE:To obtain a powerful flux convergence-type solenoid pump with a simple structure, good efficiency and high delivery amount by constituting a conductor disc through increasing the thickness of the central part of the disc so that the radial section of the disc is approximately formed into a T-shape. CONSTITUTION:In a conductor disc 2, the thickness of the periphery 10 of a central hole is made greatly thicker than other parts so that the radial section of the disc is approximately formed into a T-shape, and a spiral exciting coil 1 is combined with the periphery into a unit element. Then, when the spiral exciting coil 1 is cascade-connected appropriately and three-phase AC voltage is applied to both sides of the coil, the travelling magnetic field of a uniformly distributed high flux density is generated in a gap 9 and a strong axial thrust is generated by the interaction with an eddy current generated in a molten metal in the gap 9 to act as a solenoid pump for rolling the molten metal. As a result, a leakage flux decreases while an effective flux in the gap of a double-structure pipe increases, and a thrust acting on the molten metal further increases so that rolling characteristics of the solenoid pump are improved.
