带前腔室的湿转子泵
摘要：
本发明涉及一种湿转子泵（1），该湿转子泵带有一个定子（3）和一个被密封管（2）隔开的转子（5，6）。该转子包括一个转子轴（5）和一个转子组合（6），转子被支承在通过密封管（2）所形成的转子室（4）里，并且可旋转。其中，转子轴（5）在一个轴向端部带有一个促进液体流动的叶轮，此叶轮（7）设置在泵腔室（15）内，密封管（2）在叶轮端部具有一个大致径向向外延伸的凸缘（8），在密封管（2）与转子轴（5）之间设置了一个带有轴承（10）的轴承座（9），为了支承转子轴（5），此轴承座是被密封管（2）支撑着。在叶轮（7）和凸缘（8）之间有一前腔室（11），此前腔室在朝叶轮（7）方向是被一隔离体（12，12a，12b）限制的，其中，前腔室（11）是通过通道（13，14，34）与转子室（4）连通的。
摘要（英）：

The invention relates to a wet rotor pump, which comprises a stator (3) and rotors (5, 6) separated by a sealed pipe (2). The rotor comprises a rotor shaft (5) and a rotor combination (6), wherein the rotor is supported in a rotor chamber (4) formed by the sealed pipe (2) and is rotatable. Wherein, an impeller is arranged on an axial end of the rotor shaft (5) for promoting liquid flow, and the impeller is arranged in a pump chamber (15). The sealed pipe (2) includes a radially outwardly extending flange (8) at an impeller side end. A bearing support (9) with a bearing (10) for bearing the rotor shaft is arranged between the sealed pipe (2) and the rotor shaft (5). The bearing support (9) is supported by the sealed pipe (2). A pre-chamber (11) lies between the impeller (7) and the flange (8), and is limited by a dimensionally-stable separator (12, 12a, 12b) in a direction facing to the impeller (7), wherein the pre-chamber is communicated to the rotor chamber (4) by channels (13, 14, 34).
