Technical Field

The invention relates to the technical field of vortex pumps, in particular to a technical scheme for expanding the application field of a vortex pump.

Background

The vortex pump occupies the half-wall river mountain of the pump product market by virtue of the characteristic of high lift, but due to the structural characteristic, when the vortex pump works for a certain time, an impeller chamber and an impeller in a pump body are abraded to cause performance reduction, and when more solid impurities appear in fluid, the abrasion is accelerated to cause rapid performance reduction, even cause the pump body to be damaged, so that the vortex pump can only be used for conveying the fluid which almost does not contain the solid impurities, such as oil or clean water, and the characteristic of high lift cannot be fully exerted in various fields.

Detailed Description

Referring to fig. 1 and 2, the invention is a novel vortex pump, the core of which mainly comprises a pump body 1, a bracket 2, an impeller chamber 6 and an impeller 3. The impeller chamber 6 is arranged in the pump body 1 and is a cake-shaped inner cavity. One side of the pump body is provided with a water inlet A and a water outlet B which are opposite, and a partition 7 is arranged between the water inlet A and the water outlet B. The bracket 2 is positioned outside the pump body 1 and fastened thereon, and the rotating shaft 4 of the impeller 3 is supported on the bracket 2. The two sides of the impeller 3 are both provided with embedding grooves III3.2 which are concentric with the impeller 3, and a ceramic ring III3.1 is respectively embedded in each of the two embedding grooves III 3.2. The end face of the center of the impeller chamber 6 is provided with a flow channel body I1.1, the end face of the flow channel body I1.1 is provided with an embedding groove I1.3, and a ceramic ring I1.2 is embedded in the embedding groove I1.3. The end face of the support 2 is provided with a flow channel body II2.1, and the flow channel body II2.1 and the flow channel body I1.1 form mirror symmetry. An embedding groove which is the same as the embedding groove I1.3 is arranged on the end face of the flow passage body II2.1, and a ceramic ring II2.2 which is the same as the ceramic ring I1.2 is embedded in the embedding groove. One end of the rotating shaft 4 penetrates through the support 2, and the impeller 3 is matched between the flow channel body I1.1 and the flow channel body II2.1, and a small matching gap is reserved between the two. The impeller 3 is clamped between two symmetrical flow passage bodies to rotate, and liquid on one side is brought to the other side. The ceramic ring III on the impeller 3 is the same as the ceramic rings I1.2 and II2.2 on the two runner bodies in size and is positioned on the same central line. And a mechanical sealing gasket 5 is arranged at the matching part of the rotating shaft 4 and the flow channel body II2.1 for sealing.

The working principle of the invention is briefly described as follows:

in the conventional vortex pump, when a fluid medium containing solid impurities enters the impeller chamber 6 from the water inlet a and rotates at a high speed through the impeller 3, the impurities enter a matching gap between the channel body and a matching end surface of the impeller (a matching position of the channel body end surface and a ceramic ring of the impeller end surface in fig. 1), the matching end surfaces on the two sides begin to be worn, the gap is increased, the performance is reduced, and the function of pressurization is finally lost. In the invention, when solid impurities enter the matching end surfaces of the flow channel body and the impeller, the solid impurities cannot abrade the end surfaces of the flow channel body and the impeller due to the super-strong wear-resisting characteristic of the ceramic ring, and finally the pressurization conveying of the fluid containing the solid impurities is realized.
