Abstract

The invention discloses a water conservancy engineering impeller based on a high-speed centrifugal magnetic pole cutter, which includes a wheel body, a central shaft body, an outer ring sleeve shaft and an impeller body, the outer ring sleeve shaft is installed outside the central shaft body, the central shaft body and the impeller body The shafts of the outer ring are rotatably connected to the wheel body through a connecting frame; the outside of the shaft of the outer ring is fixedly connected with a rotating seat, and the outer side of the rotating seat is rotatably connected with a retractable internal cutting cutter. An inner groove is provided at the inner side of the incision crushing knife, and the inner groove is equipped with a recovery and reset device. The present invention relates to the technical field of water conservancy engineering. The water conservancy project impeller based on the high-speed centrifugal magnetic pole cutter has different components at both ends of the impeller assembly, which can make more effective use of water energy, and can effectively improve the service life of the impeller and reduce the number of repairs and maintenance. It ensures that the cutting force of the device during work also ensures the working efficiency of the impeller.

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. [0003] In water conservancy...
