摘要
针对现有螺杆泵驱动装置存在箱体油封和盘根盒处漏油、结构尺寸过大和防反转机构不可靠等问题 ,研制了新型大功率螺杆泵驱动装置。新型装置的关键技术在于将现有驱动装置的圆柱斜齿轮传动改为圆锥齿轮传动 ,电动机卧式放置 ;在原调心轴承下部增加一个扶正轴承 ;支座与传动轴之间除盘根盒密封外 ,另在下部增加机械密封作为双道密封保险 ;采用新型楔块式超越离合器作为防反转机构。 34台新型装置在大庆油田和大港油田的推广应用表明 ,这种装置在整个螺杆泵系统检泵周期内完全可以达到不渗不漏的质量要求 。
In the light of the disadvantages of the existing driving unit on screw pump, a new high-power driving unit is developed.The key techniques of the new u nit lie in :(1) the column helicai drive on the previous unit is replaced by bev el gear drive with the electric motor installed horizontally; (2) an alignment b earing is added below the previous self-aligning bearing; (3) adding mechanical seal below the packing box; (4) applying new wedge overru nning clutch as anti-reverse mechanism. Use in Daqing Oilfield and Dagang Oilfie ld shows that the new driving unit can satisfy the service requirement in the pr oduction of oil fields.
