Title:
ROTARY INERTIAL IMPELLER
Document Type and Number:
WIPO Patent Application WO/2018/040094
Kind Code:
A1
Abstract:
A rotary inertial impeller comprises a shaft (1) and a blade. An inner end of the blade is connected to the shaft (1). The blade is an ordinary blade or an inertial blade (7). A rotation radius R0 of the inertial blade (7) is greater than or equal to 0.72 times of a length R1 of the inertial blade (7). The rotary inertial impeller further comprises a first inertial weight ring (8) fixedly connected to or hinge-connected to an outer end of the inertial blade (7) and having a weight greater than 0.38 times of the total weight of the inertial blade (7), and/or comprises a second inertial weight ring (9) fixedly connected to the shaft (1) by means of a support (2). A ratio of the moment of inertia of the rotary inertial impeller to the total moment of inertia of the blade falls within the range of [1, 8]. The rotary inertial impeller can be widely applied in hydraulic turbines, wind turbines, steam turbines, motors, aircrafts, and ships, enabling power equipment to fully utilize the inertial effect of the blade and the inertial weight ring, thereby achieving energy conservation and efficiency.
