Embodiment Construction

[0038] The present invention is further illustrated below by means of examples, but the present invention is not limited to the scope of the examples.

[0039] like figure 1 As shown, this embodiment discloses a magnetic drive pump. The magnetic drive pump includes an isolation cover 200 and an impeller 300 . The magnetic drive pump also includes a pump casing 110 , an intermediate bracket 120 and a bearing bracket 130 connected in sequence.

[0040] The isolation cover 200 and the impeller 300 are accommodated in a space formed by the pump casing 110 and the intermediate bracket 120 .

[0041] Wherein, the outer magnetic drive assembly 420 includes an outer magnet, and the outer magnet is arranged outside the isolation cover and corresponds to the inner magnet arranged inside the impeller 300 .

[0042] When working, the outer magnet on the outer magnetic drive assembly 420 drives the inner magnet in the impeller 300 to move through magnetic force, thereby driving the impell...

Abstract

The invention discloses an isolation cover, a pump assembly and a magnetic drive pump. The interior of the isolation cover comprises a protruding part for supporting an impeller shaft, wherein the protruding part extends in the longitudinal direction of the isolation cover; the impeller shaft is fixedly connected to the protruding part. The pump assembly comprises the isolation cover and an impeller. By adopting the isolation cover, the pump assembly and the magnetic drive pump, the whole liquid end is simple in structure, and the isolation and supporting functions are achieved. Thus, by adopting the three components including the isolation cover, the impeller and a pump case, dismantling and maintenance of the pump are greatly facilitated without complicated technical training and special tools, just like stacking and dismounting of building blocks.

Description

technical field [0001] The invention relates to an isolation cover, a pump assembly and a magnetic drive pump. Background technique [0002] In existing magnetic drive pumps, the outer magnetic drive assembly is usually connected to the motor shaft for rotation, so that the inner magnet mounted on the impeller is driven by magnetic force to make the impeller rotate. Usually, the pump body is provided with an isolation cover for sealing to prevent liquid leakage. [0003] The isolation cover is the isolation cover between the outer magnetic drive and the inner magnetic drive in the magnetic drive pump. It is used in the magnetic drive pump and has the following functions: 1. Seal the liquid at the liquid end with a certain strength and rigidity to ensure that the liquid is within the pressure range The work is reliable and does not leak. 2. The magnetic field of the outer magnetic drive can act on the inner magnetic drive through the isolation cover and drive the impeller t...
