Abstract
The utility model discloses a magnetic rotor structure in a magnetic pump. The magnetic rotor structure comprises a rotor seat (1), a magnetic block fixing ring (2), a magnetic block (3), partitioning pads (4a and 4b), a covering sleeve (5) and a covering sleeve baffle (6), wherein the outer-ring section of the magnetic block fixing ring (2) is an equilateral polygon; the inner end surface of the magnetic block (3) is a flat surface; the outer surface of the magnetic block (3) is an arc adopting the rotor axis as the radius; and the outer-ring surface of the magnetic block (3) is provided with the covering sleeve (5). The magnetic rotor structure disclosed by the utility model has the advantages that the structure is reasonable, the defects and the bad influence caused by gluing of the magnetic block (3) are effectively eliminated, and good anti-rotation effect is achieved to the magnetic block (3) by utilizing the positioning action of the polygon.
Description
Technical field
The utility model relates to magnet rotor in the magnetic drive pump, especially for the internal rotor of the magnetic drive pump of carrying high temperature media.
Background technique
Magnetic patch itself in the existing technology magnetic drive pump on the magnet rotor is a shape in the arc-shaped; Be to adopt the bonding mode of special adhesive to be fixedly connected between the magnetic patch retaining ring of magnetic patch and internal rotor; For magnet rotor in preventing directly contacts with the medium of pumping; Produce dielectric corrosion, portion is fixed with jacket at rotor exterior ring.But under high temperature action, cause adhesive failure, the slippage of rotor magnetic patch easily.In addition, in bonding process, once in rotor magnetic patch bonding plane, leave air, under high temperature condition, can produce air expansion, magnet rotor produces the phenomenon of bulge, demagnetization in making, and causes magnetic drives to lose efficacy, and has a strong impact on the magnetic drive pump proper functioning.
The model utility content
The purpose of the utility model is to improve to the shortcoming deficiency of above-mentioned existing technology, and magnet rotor in the good magnetic drive pump of a kind of structure stability is provided.
Magnet rotor comprises rotator seat 1, magnetic patch retaining ring 2, magnetic patch 3, dottle pin 4a, 4 in the utility model magnetic drive pump
b, jacket 5, jacket baffle plate 6; On rotator seat 1 outer ring surface, offer seam 61; Magnetic patch retaining ring 2 cooperates and is installed on the seam 61 that rotator seat 1 outer ring surface offers; And fixing through key 7 with rotator seat 1, magnetic patch retaining ring 2 is that one or polylith are formed side by side, in the right ends of magnetic patch retaining ring 2 dottle pin 4a, 4 is set respectively
B,At rotator seat 1 seam 61 opening ends jacket baffle plate 6 is set; Jacket baffle plate 6 is welded to connect with rotator seat 1; Magnetic patch 3 is arranged and is placed in magnetic patch retaining ring 2 outer surfaces, and the outer shroud cross section of magnetic patch retaining ring 2 is an equilateral polygon, and the interior edge face of magnetic patch 3 is the plane; The outer ring surface polygonal hem width of magnetic patch 3 width and magnetic patch retaining ring 2 is wide; The outer surface of magnetic patch 3 is for being the circular arc of radius with the rotor axis, at the outer ring surface of magnetic patch 3 jacket 5 is set, and the right ends of jacket 5 is welded to connect with rotator seat 1 and jacket baffle plate 6 respectively.
The utility model is rational in infrastructure, has effectively eliminated magnetic patch 3 because the defective of gluing generation and the harmful effect that causes.Utilize polygonal positioning action, magnetic patch 3 is played good anti-rotation effect.
