AI Technical Summary
Technical Problem
When handling liquids containing solids, existing pumps are prone to clogging or entanglement of solids around the guide pin, leading to unnecessary reverse operation and costly maintenance requirements.
Method used
An improved impeller housing is designed by setting specific angles for the rear and front edges between the guide pin and the impeller housing, so that solid material is pushed towards the center when the impeller rotates in the reverse direction to avoid entanglement, and is scraped off when it rotates in the forward direction, ensuring that solid material passes through the pump.
Benefits of technology
It effectively removes solid matter, reduces reverse operation time, improves pump reliability and efficiency, and reduces maintenance costs.

Abstract
本发明涉及一种用于泵的叶轮座(5)，所述叶轮座(5)有进口壁，其中，叶轮座(5)有进口半径，该进口半径从轴向延伸中心轴线(A)至在叶轮座(5)的进口壁和上表面(12)之间的圆形相交部分(11)测量，所述叶轮座(5)包括引导销(13)，该引导销与所述进口壁连接，并从所述进口壁径向向内延伸，引导销(13)有尖端半径，该尖端半径从轴向延伸中心轴线(A)至引导销(13)的径向最内侧部分测量，其中，假想15％圆(23)从所述圆形相交部分(11)径向向内偏移在所述进口半径和所述尖端半径之间的差值的15％，假想85％圆(24)从所述圆形相交部分(11)径向向内偏移所述进口半径和所述尖端半径之间的差值的85％。叶轮座(5)的特征在于，后边缘线(28)是在假想15％圆(23)和引导销(13)的后边缘(27)之间的相交部分以及在假想85％圆(24)和引导销(13)的后边缘(27)之间的相交部分之间延伸的轴向凸出直线，在假想15％圆(23)处与引导销(13)的后边缘(27)相交的叶轮座(5)的半径和后边缘线(28)之间的后边缘角(α)等于或大于10度且等于或小于30度。本发明还涉及一种包括该叶轮座的泵。
