Screw pump

The invention relates to a screw pump having a spindle housing (2), in which a drive spindle (3) and at least one output spindle (4) which meshes with the drive spindle are accommodated in a spindle bore (28), and having an outer housing (5) which surrounds the spindle housing (2) and on which an axial inlet connection (6) and a radial outlet connection (9) are provided, wherein the spindle housing (2) has an axial fluid outlet for fluid conveyed through the spindle housing (2) via the driving and driven spindles (3, 4), which axial fluid outlet communicates with a fluid chamber (10) extending 360 DEG built between the spindle housing (2) and the outer housing (5), the fluid chamber in turn communicates with the radial outlet connection (9). 一种螺杆泵，其具有主轴壳体(2)，在所述主轴壳体中，驱动主轴(3)和与所述驱动主轴啮合的至少一个从动主轴(4)容置在主轴钻孔(28)中，且其具有包围所述主轴壳体(2)的外壳体(5)，在所述外壳体上设有轴向入口接头(6)和径向出口接头(9)，其中所述主轴壳体(2)具有轴向流体出口，用于经由所述驱动主轴和所述从动主轴(3、4)被输送穿过所述主轴壳体(2)的流体，所述轴向流体出口与构建在所述主轴壳体(2)与所述外壳体(5)之间的延伸360°的流体室(10)连通，所述流体室又与所述径向出口接头(9)连通。
