A wheel hub inducer matched with a support column

Abstract

The invention discloses a wheel hub inducer matched with a support column. The invention includes an inducer and an enclosure structure; the main body of the enclosure structure is a hollow cylindrical structure, the inducer and the enclosure are fixedly connected coaxially, the inducer is installed inside the enclosure, and the fluid flows between the enclosure and the inducer , the upper end face of the inducer is used as the inlet end of the fluid, the lower end face of the enclosure structure is used as the outlet end of the fluid, and the enclosure structure is connected with the centrifugal impeller, so that the hub inducer is fixedly installed on the centrifugal impeller. The invention can increase the design flow of the inducer, and can be used in conjunction with a centrifugal pump with a large flow to save the materials consumed in the manufacture of the inducer, and at the same time improve the cavitation performance of the centrifugal pump to a certain extent; it can save materials, thereby reducing costs; Compared with the inducer of the same size and specification, the length of the axial flow channel is increased, which can better compress the cavitation on the outer edge of the inducer, so that it collapses after reaching the high pressure area, thus greatly limiting the development of cavitation.

Description

technical field [0001] The invention relates to an inducer in the technical field of centrifugal pumps, in particular to a hub inducer matched with a support column. Background technique [0002] The centrifugal pump inducer is the impeller front inducer, which belongs to the axial flow impeller and is installed in the front of the centrifugal pump impeller. The centrifugal pump can use the lift generated by the inducer to boost the centrifugal pump impeller behind. In the centrifugal pump impeller, when the cavitation develops to a certain extent, it will affect the external characteristics and reduce the performance. This is because the liquid flows from the axial to the radial direction in the flow channel, and the flow channel between the blades in the inducer is relatively small. It is long and axial, and there is no centrifugal force that promotes the separation of bubbles and liquid. The relative flow rate is the largest at the outer edge of the impeller. Therefore, c...

Problems solved by technology

[0003] In actual industrial production, the hub of the traditional inducer mostly adopts a conical structure. Although the stability can be guaranteed, the material consumption is relatively large, and under the same size, the designed flow rate of the inducer is limited to a certain extent. In order to solve the problem of traditional induction Due to the problems existing in the impeller design, it is necessary to design a more reasonable inducer structure, which can significantly and effectively improve the performance of the centrifugal pump impeller
