油气辊输泵设计中若干问题的探讨

Discussion on Several Problems of Oil-Gas Mixed Transferring Pump

油气混输泵及其系统工程的研究，因海洋采油工程的崛起，再次掀起高潮，是一项市场前途见好的研究课题。非密闭螺杆是油气混输泵设计思想的一个突破。在线密封混输泵的基础上重．或探讨了非密闭螺杆的工作原理，还介绍了非密闭螺杆的设计参数，计算公式，设计方法，同时还对混输泵的结构设计作了探讨。

On the basis of linear closed mixed pump,this article discusses the work principle of disclosedscrews. the article also introduces the design parameters, calculation formulas and design methodof disclosed screws,at the same time the structuredesign of mixed transferring pump has been discussed.
