VARIABLE-SECTION DUAL INTAKE CHANNEL TURBINE

摘要

A variable-section dual intake channel turbine includes a volute (4), a volute nozzle (6) is located on the volute, and a turbine impeller (8) is mounted in the volute. A volute intake channel (10) is located on the volute, a middle wall (20) is located in the volute intake channel, and the middle wall divides the volute intake channel into a small volute intake channel (18) and a big volute intake channel (19). The radial section of the middle wall is an arched structure whose radian is in a range of 60° to 180°. The turbine has simple structure, low cost and high reliability.
