Abstract
The utility model relates to an outer magnetic rotor structure of a magnetic pump. The outer magnetic rotor structure comprises an outer magnetic rotor seat (1), a magnetic block fixing ring (2), a magnetic block (3) and a wearing ring (4), wherein a plurality of right-angle type grooves with aequilate side width, namely magnetic block mounting grooves (20) are uniformly distributed on the inner ring circumferential surface of the magnetic block fixing ring (2), the outer ring end surface of the magnetic block (3) is of a plane, and the magnetic block (3) is matched and mounted in the magnetic block mounting grooves (20) formed on the inner ring surface of the magnetic block fixing ring (2). The magnetic block utilizes the matching of the grooves for positioning, the fixation is stable, the anti-shedding and anti-rotation effects are good, the structure is simple and reasonable, and the adverse effects caused by adhesive defects can be effectively eliminated.
Description
Technical field:
The utility model relates to magnetic drive pump, especially for the outer magnet rotor of the magnetic drive pump of carrying high temperature media.
Background technique:
Magnetic patch itself on the outer magnet rotor of existing technology magnetic drive pump is a shape in the arc-shaped, and the inner ring surface of magnetic patch and external rotor seat adopts the gluing mode that connects to be fixedly connected.As bonding bad, draw under the attraction force acts at interior commentaries on classics magnetic in the operation process, can cause making the magnetic patch slippage, have 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, provides the good magnetic drive pump of a kind of structure stability outer magnet rotor.
The utility model comprises outer magnet rotor seat 1, magnetic patch retaining ring 2, magnetic patch 3, wearing ring 4; On rotator seat 1 inner ring surface, offer seam 6; Magnetic patch retaining ring 2 cooperates and is installed on the seam 6 that rotator seat 1 inner ring surface offers, and fixing with rotator seat 1 through key 5, and wearing ring 4 is through being bolted on rotator seat 1 external port; Magnetic patch retaining ring 2 is that one or polylith are formed side by side; Magnetic patch 3 is arranged and is placed in magnetic patch retaining ring 2 internal surfaces, distributes evenly on the interior ring circumferential surface of magnetic patch retaining ring 2 that to offer the wide right angle type groove of some hem widths be magnetic patch mount grooves 20, and the outer shroud end face of magnetic patch 3 is the plane; Magnetic patch 3 cooperates and is installed in the magnetic patch mount grooves of offering on magnetic patch retaining ring 2 inner ring surfaces 20, and the interior ring end face of magnetic patch 3 is for being the circular arc of radius with the rotor axis.
The outer straight shape of circle in the utility model magnetic patch 3 adopts; Cooperate establishing in the right angle type magnetic patch mount grooves 20 of evenly being distributed on the interior ring circumferential surface that is installed in magnetic patch retaining ring 2; The N utmost point and the S of adjacent magnetic patch are extremely opposite, and the effect that utilizes strong magnetic to attract each other is stably fixed on the internal ring wall of external rotor magnetic patch retaining ring 2 magnetic patch 3, magnetic patch 3 and groove fit location; Fixing-stable, the anticreep anti-rotation is effective.
The utility model is simple and reasonable for structure, has effectively eliminated because the harmful effect that gluing defective causes.
