DEVICE for PROTECTION of Centrifugal pump AGAINST cavitation

摘要

Centrifugal pump protection device against cavitation includes a pump, suction pipeline and narrowing passage connecting those. In the larger flange of narrowing passage recess is formed, which on the inner surface of the pipeline with the pipeline flange forms a chamber with a slit nozzle, and its side surface is curved at the side of narrowing passage in rounded shape towards the pump. The width H of the slit nozzle and the tip radius R, with which this surface is delineated, is described by the relation R / H = 2,0 + 15,0.
