Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

A vertical magnetic drive pump, as shown in fig. 1-2, comprises a bracket 1, a motor 2, a connecting frame 3, a pump body 4, a bearing seat 5, an impeller 6, an external magnetic rotor 7 and an internal magnetic rotor 8; motor 2 and link 3 are vertical to be set up on support 1 to motor 2 is fixed in the upper end of link 3, realizes through the flange that sealing connection between motor 2 and the link 3. The pump body 4 is arranged at the lower end of the connecting frame 3 through an isolation sleeve 9, namely, a flange of the isolation sleeve is clamped between the connecting frame 3 and the pump body 4 through a bolt. A closed cavity is formed between the connecting frame 3 and the isolation sleeve 9, an inlet connecting pipe 10 is arranged at the bottom of the pump body 4, an outlet connecting pipe 11 is arranged in the tangential direction of one side of the pump body 4, the bearing seat 5 is arranged in the inlet connecting pipe 10, the impeller 6 is arranged in the pump body 4 and is rotatably arranged on the bearing seat 5 through a bearing, and the inner magnetic rotor 8 is arranged in the isolation sleeve 9 and is connected with the impeller 6.

Because the bearing is arranged in the inlet connecting pipe 10, the rest of the transmission media are always contacted, preferably, the bearing is a silicon carbide bearing. The corrosion resistance, the wear resistance and the high temperature resistance of the bearing are utilized to prolong the service life of the bearing.

In one embodiment, as shown in fig. 1-2, the bearing block 5 is clamped between the pump body 4 and the intake nipple 10. The bearing seat 5 can be installed without additionally arranging a bracket.

In one embodiment, as shown in fig. 1-2, the upper and lower surfaces of the bearing housing 5 are provided with sealing rings 51. To ensure the tightness between the bearing block 5 and the pump body 4 and the inlet connection pipe 10, respectively.

In one embodiment, as shown in fig. 1-2, a gap is provided between the spacer sleeve 9 and the inner magnet rotor 8, and the impeller 6 is axially provided with a through hole 61. Since there is an inevitable gap between the spacer sleeve 9 and the inner magnet rotor 8 into which the transfer medium inevitably enters, in the present embodiment, by providing a gap (larger than the gap interval) and providing the through-holes 61 in the impeller 6, the entry of the transfer medium into the medium is promoted to promote the flow of material in the gap and avoid long-term accumulation in the gap.

In a preferred embodiment, as shown in fig. 1-2, the spacer 9 is provided with oblique fluid holes 91 in the circumferential direction. The flow of the transfer medium in the gap is further promoted by the mutual cooperation of the through-hole 61 and the liquid through-hole 91.

In one embodiment, as shown in fig. 1-3, the vanes of the impeller 6 are downward arranged, and the upper surface of the vanes is a smooth plane, which is beneficial to cleaning the impeller 6, i.e. the upper surface is not easy to clean because the vanes are close to the spacer 9, and the vanes are provided with a smooth plane, which is beneficial to cleaning. And the blades are arranged below the impeller 6 and impact from the inlet connecting pipe 10, so that the cleaning of the impeller 6 can be conveniently finished.

The utility model discloses when using, as shown in fig. 1-2, drive outer magnet rotor 7 through motor 2 and rotate, drive inner magnet rotor 8 and drive impeller 6 and rotate for form the low pressure in the pump body 4, and then take over 10 suction pump bodies 4 with transmission medium from the import, and take over 11 discharges from the export.

The above are only preferred embodiments of the present invention, and are not intended to limit the scope of the present invention; the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and equivalent arrangements as is within the spirit and scope of the present invention.
