Abstract

The paper deals with investigating the basic parts of torque-flow pumps (TFP) and searching for energy-efficient casing in the pump with high specific speed.

TFP are widely used, but in some cases it is necessary to disregard efficiency of the pump in order to ensure reliable operation in harsh conditions. Therefore, the TFP efficiency increase is an urgent task.

The methodology of designing "Turo" type TFP with the high-speed misaligned spiral casing was presented in the paper.

As a result of numerical studies, distribution patterns of velocities and pressures in the TFP flowing part, which allowed qualitatively evaluate the performance of the investigated casing structures were obtained. Analysis of the results indicates the feasibility of the casing housing of TFP with the misaligned spiral.

Full-scale testing was performed, and pressure and energy characteristics of TFP with different housing designs were obtained. Based on the tests, it can be argued that a new technical solution of the TFP housing with the misaligned spiral casing was obtained.

The results allow to design TFP with increased energy efficiency, and expand the scope of their use.
