| 2W.W型双螺杆泵 |
2W.W双螺杆多相混输泵结构特点:
该型泵采用双吸式结构,螺杆两端处于同一压力腔中,轴向力可以自行平衡。两端轴承采用外装式,单独采用润滑油(脂)润滑,因而不受输送介质的影响。两螺杆间用一对同步齿轮驱动,螺杆齿面间并不接触,而留有一微小间隙,介质中的杂质并不能对螺杆齿面产生直接的磨损(除冲刷外)。
除一些小排量泵外(2W.W4.0以下),一般在泵体上都带有内流式安全阀,当排放压力超过额定值时,有一定保护作用。
泵体上的进出口方向有二种,一为水平进,水平出;二为水平进,垂直向上出;用户可根据自已需要选择。 |

2W.W双螺杆多相混输泵的优点:
1、输送液体平稳、无脉动、无搅拌、振动小、噪音低。
2、有很强的自吸性能,多相混输时,含气率不高于80%,含沙量不高于500g/m3。
3、外置轴承结构,采用独立润滑,可以输送各种非润滑性介质。
4、采用同步齿轮驱动,二转子之间不接触,即使短时间空转也无妨。
5、泵体带有加热套,可以输送各种清洁或含有固体小颗粒的低粘度或高粘度介质(一般颗粒直径小于0.12-0.2mm)。
6、正确的选用材料,甚至可以输送很多有腐蚀性的介质。
7、双吸式结构,转子上没有轴向力。
8、轴端采用机械密封或波纹管机械密封,具有寿命长、泄漏少、适用范围广的特点。 |
