2W.W密封型双螺杆泵

2W.W密封型双螺杆泵

描述:

2W.W密封型双螺杆泵采用双吸式结构,螺杆两端处于同一压力腔中,轴的力可以自行平衡。

2W.W密封型双螺杆泵采用双吸式结构,螺杆两端处于同一压力腔中,轴的力可以自行平衡。两端的轴承采用处装式,单独采用润滑油(脂)润滑,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。进口方式的有二种:一为水平进,水平出;二为水平进,垂直向上出。用户可根据需要自作选择。

2W.W密封型双螺杆泵优点:

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。

2W.W密封型双螺杆泵性能范围:

1、高工作压力4.0MPa

2、流量范围 1~1000m3/h

3、温度范围-20~120℃

4、介质粘度 1~3000mm2/s,降低转速可达到106mm2/s

介质粘度对双螺杆泵性能影响较大,泵的名义排量是指在特定粘度条件下的排量,为保证泵能在较率下工作,在试验不充分时,建议按下列粘度条件选择转速:

介质粘度cSt      转速r/min

<400         1500

400 ~1200        1000

1200~3600        750

对于粘度高的介质,所应选用的转速和驱动电机功率,请与制造厂联系。
