2W.W密封型双螺杆泵选用泵应考虑的主要事项
1、介质的润滑性，清洁度、腐蚀性。
2、介质的粘度，温度。
3、介质进、出口压力，安装高度。
4、使用场合的要求。
5、订货时请注明规格、型号、设计使用压力、转速、介质粘度、温度、电机级别、介质名称。
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、造船业：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。
2W.W密封型双螺杆泵注意事项
1、装配时应将螺杆泵零件仔细清洗，检查，损坏的零件应换；
2、传动轴两万向接头装配时，应检查密封圈有否损坏，在空腔内填充润滑脂；
3、正确安装的轴承使轴转动灵活，无卡阻现象。
4、轴封安装：填料函安装时，应使填料压盖压紧螺栓位置在壳体安装窗口内，便于扳手调整螺栓；
5、排出体压紧固定时，螺母拧紧应均匀一致；
6、机械密封安装应小心，摩擦副端面应清洁并涂上润滑脂。
