Koncepcja metody zabezpieczenia pomp odśrodkowych przed skutkami zjawiska uderzenia hydraulicznego – wyniki badań laboratoryjnych

The following papper discusses the issues related to the occurrence of water Hammer phenomenon in pressure liquid transportation systems. Although the knowledge about the problem of water Hammer phenomenon Has been developer over 100 years continues to demonstrate that the systems inadequately protected against the effects of impact of water hammer are exposed to numerous accidents and various maintenance problems. The devices that particularly vulnerable to the formation of water hammer phenomenon are centrifugal pumps. The article presents an original concept of centrifugal pumps security methods based on the differential valve of their own construction and the results of laboratory tests the effectiveness of the method.
