【 摘 要 】

In the article the authors present a new type of inlet device for multistage centrifugal pumps. An overview of the existing types of inlet devices is given, their advantages and disadvantages are observed. The form of the proposed type of inlet device is described, which makes it possible to combine good cavitational properties of the pump with low losses in the inlet device. The results of hydrodynamic modeling of the proposed type of inlet device and its comparison with the existing ones are given.
