2W.W密封型双螺杆泵的优点
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。
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,为泵能在较下工作,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
对于粘度更高的介质,所应选用的转速和驱动电机功率,请与制造厂联系。
