详细介绍:

2W.W密封型双螺杆泵详细参数
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,为保证泵能在较   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   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。
2W.W密封型双螺杆泵应用举例  
  1、油田:用作油、气、水、微量细小固相颗粒等多相混输泵及原油输送泵。  
  2、造般业:用作船用装载泵,船底扫舱及污水处理,主机润滑泵,燃料油泵。  
  3、石油化学工业 :用作各种树脂、颜料、石蜡、油漆、油墨、乳胶、各种油品、原油、重油等装载和运输泵。  
  4、热电厂:用作重油、原油输送泵,主机润滑油泵。  
  5、食品工业:用作洒精、蜂蜜、糖浆、果汁、动植物油、牛奶、浆油输送泵。
