Influence of Impeller Accuracy on Axial flow Pump Efficiency

Impeller processing accuracy is not good enough? This affects not only the performance of the axial flow pump, but also affect your work, so choose the best to smooth work.
Impeller is an important part of water machinery and other hydraulic machinery, impeller machining accuracy directly affect the efficiency of the pump and the stability of the run-time. For the axial flow pump and the guide vane mixed flow pump, in order to facilitate the adjustment of the blade installation angle to meet the different requirements, usually the outer edge of the impeller designed to spherical. As the impeller outer spherical and spherical spherical surface of the gap on the hydraulic efficiency of a greater impact, so the impeller outer spherical processing technology is particularly important. General shaft, mixed flow pump impeller larger diameter, and most of the mixed-flow pump impeller, the blade centerline and impeller rotation axis tilt a certain angle, because the pump and the specific speed, the blade center line and impeller rotation axis tilt The angle is also different, such as most axial pump impeller, the blade centerline and impeller rotation axis tilt angle of 90 °.
