Embodiment Construction
[0066] Such as Figure 1 to Figure 8 As shown, it is a centrifugal pump for actively suppressing cavitation according to the present invention, which includes a volute 1 and an impeller. A cavity 2 is provided inside the volute 1 , and the impeller is arranged in the cavity 2 . The present invention also includes a compensating pipe 5. The volute 1 is provided with a compensating hole. The compensating hole is correspondingly arranged at the low pressure area where the front edge 3 of the impeller and the suction surface 4 appear. The compensating tube 5 penetrates and is fixed in the compensating hole. The compensating tube 5 Send high-pressure compensation fluid to the low-pressure area, and the compensation fluid is sent along the rotation direction of the impeller. For example, when the impeller rotates counterclockwise, the compensation fluid is delivered at high pressure from right to left image 3 ). The present invention impacts the low-pressure area that occurs during ...
