Abstract

La presente se refiere a una bomba de tornillo helicoidal para transportar un medio fluido con una carcasa de la bomba que presenta una entrada y una salida para el medio a transportar. La bomba de tornillo helicoidal comprende al menos dos tornillos. Ésta está compuesta por al menos un eje con al menos dos tramos de eje y un tramo perfilado ubicado entremedio, en donde los tramos perfilados de los al menos dos tornillos se encuentran por lo menos parcialmente engranados entre sí. Los al menos dos tornillos se encuentran ubicados al menos parcialmente en la carcasa de la bomba, apoyados en forma giratoria. Un primer tornillo esta configurado como tornillo de accionamiento. A éste se encuentra asignado un primer accionamiento directo. De acuerdo con la presente por lo menos un segundo tornillo tiene asignado un segundo accionamiento.This refers to a helical screw pump for transporting a fluid medium with a pump housing that has an inlet and an outlet for the medium to be transported. The screw screw pump comprises at least two screws. This is composed of at least one shaft with at least two axle sections and a profiled section located in the middle, where the profiled sections of the at least two screws are at least partially engaged with each other. The at least two screws are located at least partially in the pump housing, rotatably supported. A first screw is configured as a drive screw. A first direct drive is assigned to it. According to the present at least one second screw is assigned a second drive.
