Embodiment Construction
[0022] Below in conjunction with accompanying drawing, the present invention will be further described:
[0023] combine figure 1 , figure 2 As shown, the impeller of this bubble-breaking hybrid transmission submersible pump includes a front cover plate 1, a shaft sleeve 2, a rear cover plate 3, and blades. The blades are segmented blades, and there are bubble-breaking jet slots 8 , the fracture of the bubble breaking jet is disconnected in the span direction of the segmented blade, and the shape is the gap between the trailing edge of the front blade and the leading edge of the rear blade; the front blade 4 is in front of the bubble breaking jet slit 8, and the bubble breaking jet Behind the slot 8 is the rear blade 5 . The fracture of the bubble breaking jet is located between 1 / 3-1 / 2 of the chord distance of the segmented blade, the opening width is 2-5mm, the opening height is the same as the spanwise height of the blade, and the opening is inclined, which is consistent...
