Abstract

DC60 (15/03/54) In the propeller unit 11, the inlet and outlet sections are provided at one end and the other end in the axial direction, respectively, inlet 29. has been formed in the lower part of the inlet section and the exit channel has been formed in the side page of exit channel The inlet and outlet sections are separated by 40 front plates. The impeller 11 includes the main impeller 36 and the secondary impeller 38. The main impeller 36 defines the spiral-shaped main channel 35, which connects the inlet 29 and the channel. Exit The secondary impeller 38 is formed into a shape where part of the outer periphery of the outlet section is grooved inward. In order to define the secondary channel 37 connected to the main channel 35 and extend along the circumference. Around the outer periphery, in the impeller unit 11, the inlet and outlet sections are provided at the ends. one end and the other end in the axial direction, respectively. The inlet 29 is formed in the lower part of the inlet section, and the exit port is formed in the side face of the exit channel The inlet and outlet sections are divided by the front section 40, the impeller 11, including the main impeller 36 and the secondary impeller 38. The main impeller 36 defines the main channel volute 35, which connects the inlet 29 and the channel. exit. The secondary impeller 38 has been formed into shape where Part of the perimeter of the outlet section has been grooved inward. In order to define the secondary channel 37 connected to the main channel 35 and extend along the circumference. around the outer part
