REDUCING ELBOW AND PUMPING DEVICE COMPRISING REDUCING ELBOW

摘要

Provided are a reducing elbow (10) and a pumping device comprising the reducing elbow. The reducing elbow (10) is used in a fluid transmission pipeline. The reducing elbow (10) comprises an input end (10a) and an output end (10b). The radius of curvature of the reducing elbow (10) is in the increasing trend from the input end (10a) to the output end (10b). The curvature and variable diameter of the reducing elbow (10) are optimally designed, thereby effectively reducing the impact of the transmitted material on the reducing elbow (10), and extending the service life of the reducing elbow (10).
