Example Embodiment

[0015] Three preferred embodiments of the present invention are described below with reference to the accompanying drawings.

[0016] like figure 1 As shown, the first embodiment of the idling-resistant plastic magnetic pump of the present invention includes a plastic pump casing (3) divided into a front pump casing (1) and a rear pump casing (2), and an impeller chamber (9) and its interior are formed It is adjacent to the driven magnet chamber (10), and has an inlet (11) and an outlet (12) for the delivery of the target liquid. The disc-shaped impeller driven magnet set (7) is made up of the disc-shaped impeller (4) at the front end and the magnet cover (6) at the rear end, and the driven magnet (5) is installed inside the magnet cover (6). The disc-shaped impeller driven magnet set (7) is installed inside the impeller chamber (9) formed inside the pump casing (3) and the driven magnet set chamber (10) adjacent thereto. The outer wall of the protruding part of the front e...

Abstract

The invention relates to an idling resistant plastic magnetic pump. The idling resistant plastic magnetic pump comprises a plastic pump shell (3) which is divided into a front pump shell (1) and a rear pump shell (2); and the inside of the plastic pump shell forms an impeller chamber (9) and a driven magnet chamber (10) adjacent to the impeller chamber (9), and is provided with an inlet (11) and an outlet (12) which are used for providing the transportation for target liquid. A discal impeller driven magnet sleeve set (7) consists of a front-end discal impeller (4) and a rear-end magnet sleeve (6); the magnet sleeve (6) is provided with a driven magnet (5) inside. The discal impeller driven magnet sleeve set (7) is arranged inside the impeller chamber (9) and the driven magnet chamber (10) adjacent to the impeller chamber (9) formed in the inside the pump shell (3). The discal impeller driven magnet sleeve set (7) is rotatably supported by a full sealed type ceramic rolling bearing (8) which is matched with the front pump shell (1) and the rear pump shell (2). A main rotary magnet (15) is combined with the driven magnet (5) by the rear pump shell (2) through the action of a magnetic filed so as to apply driving force to the discal impeller (4) by the driven magnet (5). The inside of the discal impeller (4) forms a flow passage so as to input target liquid from the inlet (11); therefore, the target liquid is transported outside along the radial direction and exhausted from the outlet (12).

Description

technical field [0001] The invention relates to a magnetic pump, which comprises a disc-shaped impeller driven magnet set (7) rotatably supported by a pump casing (3) and a fully sealed ceramic rolling bearing installed inside. The invention particularly relates to such an anti-idling plastic magnetic pump, which is especially suitable for transporting corrosive liquid media. Background technique [0002] Existing magnetic pumps for conveying corrosive media use sliding bearings to carry the impeller for rotation, and use the conveying liquid medium as lubricant and cooling liquid. The pump casing and impeller are generally made of corrosion-resistant plastic materials, and the sliding bearings are generally With ceramic shaft and graphite bushing. When the magnetic pump is idling, it cannot be lubricated and cooled because there is no liquid medium to be transported. The ceramic shaft and graphite bushing in the sliding bearing group in the pump cause a temperature rise du...
