Creating the flowing part of the high energy-efficiency torque flow pump

Abstract: Прикладная механика У роботі розроблена методика проектування корпусу вільновихрового насоса (ВВН) з неспіввісною спіраллю. Проведено чисельний розрахунок, за результатами якого отримані картини розподілу швидкостей і тисків у проточній частині ВВН з кільцевим і неспіввісним спіральним відводами. З урахуванням аналізу чисельного експерименту розроблена і випробувана конструкція ВВН з неспіввісним спіральним відводом Ключові слова: вільновихровий насос, неспіввісна спіраль, чисельне моделювання, коефіцієнт швид… Show more

“…Paper [8] proposed a design of the TFP diffuser, which enables improving efficiency of the pump by up to 4-5 %. This is achieved through the harmonization of geometrical parameters of free chamber of the pump casing with the direction of the vortex flow.…”

“…The effect of changing the width of the impeller blade on the characteristics and structure of the flow in the torqueflow pump flowing part was researched in papers [6,7] in order to increase its efficiency and head. The solution to this issue is urgent, since the efficiency of torqueflow pumps of the "Turo" type decreases sharply in the areas of low (n s ≤ 60) and high specific speed (n s ≥ 140) [8,9].…”
