| 摘要 |
The invention relates to an eccentric screw pump for conveying high-viscosity materials, in particular liquid mortar. The eccentric screw pump according to the invention comprises a stator (12) made of an elastomer and having a pump hollow chamber (14) formed in the manner of a double- or multi-pitch thread (20) and a motorized rotor (16) having radial eccentricity (e) and reaching through the pump hollow chamber (14) and formed in the manner of a pitch thread (22). The pump hollow chamber (14) of the stator (12) has one thread more than the rotor (16). In order to obtain a good mix having a high air pore ratio, according to the invention the pump hollow space (14) opens on the pressure side end of the stator (12) in a mixing chamber (28) in which a mixing element (30) which is connected to the rotor (16) in a rotationally fixed manner engages. |
