对邢子文提出的双螺杆多相流混输泵专用型线的几何性能和密封性能进行了探讨,重点讨论了其啮合线、接触线长度及泄漏三角形面积的计算方法.通过对型线齿型密封性能的综合分析,认为不同齿型双螺杆泵的第2类密封条件可以有不同的表达式;该单头双螺杆多相流混输泵对称型线虽然不满足孟氏第2类密封性定律,但却是严格密封型齿型
The geometrical performance and sealing performance of Xingziwen special twin-screw multiphase flow pump are discussed, and the calculation method of the meshing line, contact line length and leaking triangle area are discussed emphatically.At the same time, The results show that there are different expressions for the type-2 sealing conditions of different gear type twin-screw pumps. The symmetrical profile of the single-head twin-screw multiphase flow mixing pump does not satisfy the Monte-Carlo Class 2 sealing law , But it is strictly sealed tooth type
