Centrifugal pump inlet elbow

机译:离心泵入口弯头

摘要

A suction elbow device for a centrifugal pump, in which a current directed at an angle of preferably at least approximately 90º to the axis of the pump shaft, is diverted to an impeller arrival current parallel to this axis, characterized because the areas of the cross sections normal to the elbow current decrease continuously from its entrance to its circular outlet which is preferably immediately in front of the impeller, and because the elbow forms in the middle zone a cross section at least similar to an ellipse, whose minor axis is in the median plane of the elbow, and has in the said middle zone the smallest separation between the inner and outer walls within this median plane of the elbow.
