Abstract |
В статті розглядається робочий процес малогабаритного осьового ступеня низької швидкохідності (ns = 250 - 400) з лопатями малого подовження. Отримано уточнені рівняння сумарних гідравлічних втрат для зазначених проточних частин, точність та достовірність яких підтверджено за допомогою чисельного моделювання та фізичного експерименту. The theses present results of a study of a small-sized axial-flow stage with blades of small aspect ratio, which is designed for submersible borehole pumps. The energy losses in the flow section of stage are analyzed in research. Refined equations of total hydraulic losses for these flow parts were received by numerical simulation. The results of numerical simulation are compared with experimental data obtained at a test rig. |
