<p>A pump rotor is characterized by the fact that the rear shield diameter ( 1 ) is from 0.99 to 0.70 of the frontal shield diameter ( 2 ), whereas outlet blade( 2 ) edges ( 2 ) are parallel on its all length to the axis of rotor rotation. Outlet blade edges have got skips to be al wide, being from 0.01 to 0.9 of rotor discharge channel width; however its height a2 is from 0.01 to 0.5 of its width.</p> |
