Reducing bent pipe and pumping equipment with same

Abstract

The invention provides a reducing bent pipe and pumping equipment with the same, and integrally relates to the field of material conveying. The reducing bent pipe is used in a fluid transportation piping, comprises an input end and an output end, and is characterized in that the radius of curvature of the reducing bent pipe increases from the input end to the output end. As the bending and the reducing degree of the reducing bent pipe are optimally designed, impact of transported materials on the reducing bent pipe can be effectively reduced, and the service life of the reducing bent pipe canbe prolonged.

Description

technical field [0001] The invention relates to the field of material conveying, in particular to a reduced-diameter elbow for conveying materials and pumping equipment including the reduced-diameter elbow. Background technique [0002] With the rapid development of the concrete industry, especially the widespread use of high-grade high-performance concrete, this also puts forward higher requirements for the vulnerable components and key components of the concrete pumping equipment, such as the concrete delivery involved in the present invention Reducer elbow. [0003] For pumping equipment such as pump trucks and towed pumps, the delivery pipeline is mainly composed of straight pipes and curved pipes. At present, most of the commonly used delivery elbows are variable-diameter elbows. The resistance at the corner of the variable-diameter elbow is relatively large, and its inner diameter changes from large to small. When the concrete flows through, it will continuously squee...

AI Technical Summary

Problems solved by technology

At present, most of the commonly used delivery elbows are variable-diameter elbows. The resistance at the corner of the variable-diameter elbow is relatively large, and its inner diameter changes from large to small. When the concrete flows through, it will continuously squeeze and wash the curved pipe wall of the variable-diameter elbow. As a result, the service life of the reducing elbow is not only much lower than that of the straight pipe, but also much lower than that of the ordinary non-reducing elbow

On the other hand, the pipe blockage generally occurs at the position of the reducing elbow in the conveying pipeline, which often causes construction interruptions. The small ones delay the construction progress, and the large ones cause safety accidents due to pipe bursts.
