Abstract:
The increase in the efficiency and competitiveness of mining enterprises is limited by the insufficient efficiency and adaptability of the currently used centrifugal pumps. Using the vortex theory of turbomachines, Theorems Stokes’ and Helmholtz, the principles of hydrodynamic analogy and superpositions, a mathematical model of the hydrodynamic calculation of centrifugal pumps with adaptive vortex sources integrated into the impeller blades is obtained. A significant influence on the hydrodynamic parameters and adaptability of pumps of the energy characteristics of adaptive vortex sources has

The article is devoted to the analysis of the hydrodynamic causes of complications of the use of centrifugal pumps in artificial circulation systems. In the treatment of cardiovascular diseases, rotary pumps began to be used: centrifugal, axial and disk. Of the three types of rotary pumps, centrifugal pumps have the highest power density due to the use of centrifugal force. Statistics show that the greatest blood damage in the form of thrombosis and hemolysis is observed in these pumps.

Abstract:
A hydraulic device that is used to suck up liquid, move it under pressure or pump it, is called a pump. As a rule, any movement of a liquid by similar aggregates is carried out due to the transfer of potential or kinetic energy to it. Depending on the technical indicators, different types of pumps are used. At the same time, they differ in efficiency, power, volumes of fluid pumped per unit time, maximum head and resulting pressure. The most used group of pumps are vane pumps. Their distinctive feature is the impeller rotating in a fixed housing, equipped with blades. Depending on the warehous

One of the most common types of pumping units used in industry are centrifugal pumps. In turn, there is a classification of centrifugal pumps according to design features. So-called low specific speed pumps are designed for low flow and high pressure. This type of pump is widely used in the chemical and oil industries due to its operating conditions, which involve overcoming the resistance of long technological pipelines. At the same time, low specific speed centrifugal pumps have low energy efficiency due to extensive vortex formation the moving fluid inside the flow area. In order to increas

The difficult operating conditions of oil pumps require high levels of reliability, durability and efficiency from hydraulic machines. The gas dissolved in oil leads to the appearance of regions with variable density in the pumps flow parts and to a breakdown in performance. The use of jet pumps is limited due to low efficiency. Therefore, the operation of new vortex chamber pumps for oil production and transportation is quite promising due to the increase in pumping efficiency indicators using the advantages of centrifugal and jet technology in these pumps.

Abstract:
Conventional single stage centrifugal pumps are mostly designed with a spiral volute. Due to relative movement between impeller and the asymmetric volute the flow at the outlet of the impeller is strongly interacting with the volute flow. The unsteady phenomenon leads to unbalanced radial dynamic forces as well, especially at off-design points, giving rise to pump vibration and hydraulic noises. In order to weaken the unsteady phenomenon, a special kind of slope volute is designed. Different from the spiral one, it keeps the radial size of the volute casing unchanged, but increasing the axial
