Hydraulic engineering impeller based on high-speed centrifugal magnetic pole cutters

Abstract

The invention discloses a hydraulic engineering impeller based on high-speed centrifugal magnetic pole cutters and relates to the technical field of hydraulic engineering. The hydraulic engineering impeller based on the high-speed centrifugal magnetic pole cutters comprises a wheel body, a center shaft body, an outer ring sleeve shaft and an impeller body, wherein the outer ring sleeve shaft is installed on the outer side of the center shaft body, and the center shaft body and the outer ring sleeve shaft are rotationally connected with the wheel body through a connecting frame. The outer sideof the outer ring sleeve shaft is fixedly connected with a rotating base, the outer side of the rotating base is rotationally connected with retracting and extending internal cutting smashing cutters,containing inner grooves are formed at the positions, located on the inner sides of the retracting and extending internal cutting smashing cutters, of the outer portion of the outer ring sleeve shaft, and retracting and resetting devices are installed in the containing inner grooves. According to the hydraulic engineering impeller based on the high-speed centrifugal magnetic pole cutter, different components are arranged at the two ends of an impeller assembly correspondingly, water energy can be more effectively utilized, the service life of the impeller can be effectively prolonged, and therepair and maintenance frequency is reduced. The cutting stress is ensured during working of the device, and the working efficiency of the impeller is also ensured.

Description

technical field [0001] The invention relates to the technical field of hydraulic engineering, in particular to a hydraulic engineering impeller based on a high-speed centrifugal pole cutter. Background technique [0002] The research in the field of fluid machinery mainly focuses on the optimal design of turbine blades and wind turbine blades. At present, with the rapid development of computational fluid dynamics and computational structural mechanics, research on the optimal design of axial flow pump impellers in the disciplines of hydraulic performance and structural performance is relatively abundant, and many achievements have been made. However, this traditional single-subject optimization analysis method actually ignores the interaction and mutual influence between hydraulic design and structural design, does not achieve real coordinated design, and does not have enough confidence in the reliability and accuracy of optimal design results.
