<p>The hydrodynamic power screw (1) has a single-or multi-start working screw (2) which is rotatably connected with a jacket pipe (4) for holding the working water. The jacket pipe surrounds the working screw. The jacket pipe comprises a liquid inlet and a lower-lying liquid outlet. The underlying bearing of the hydrodynamic power screw takes place by straps (5) embracing the jacket pipe from below. The straps embrace a rotatable attachment (6) above the jacket pipe from above. This attachment serves simultaneously as a power take-off.</p> |
