Method for controlling or regulating multi-layered hydrodynamic performance transition of hydrodynamic machine

摘要

The hard metal plate (1) comprises a quadratic base shape with two extending and opposite-lying longitudinal sides (3) in the axial direction of the bore shaft (51) that partially occupies the seat. There are two opposite-lying axial short sides (5) on the seat?s to-be-used radial base side (7) and a roof-like cutting face side (9) off the seat. Both short sides are formed via an axial section (33) with an axial direction component and an inclined conical section (37) in an axial direction component.
