Example Embodiment

[0032] Example 1: The diameter of the cleaning pipe is 28mm. Choose a reasonable washer. The number of rotating blades is 12, and the maximum diameter (second diameter) of the rotating blades is 26mm. It is guaranteed that the maximum diameter of the rotating blades and the pipe wall The distance between the two is less than 5mm; put the washer into the pipeline, use 1MPa water flow to push the washer to move, make the washer move linearly in the pipeline with additional rotating motion, when the pushing distance reaches 1100m, take it out for the next pipeline cleaning; A water flow is introduced into the cleaned pipeline to flush the broken dirt out of the pipeline.

Abstract

The invention relates to a rotary-vane cavitating jet type pipeline cleaner which comprises a center shaft and rotary vanes, wherein the rotary vanes are uniformly distributed on the outer surface ofthe center shaft and are spiral. The cleaner is put into the pipeline, and is pushed to move in the pipeline through pressure water flow. When the water flow flows through gaps between the vanes of the cleaner and the pipeline wall, the speed is increased and the pressure is reduced; and when the pressure is lower than saturated vapor pressure of water, cavitation occurs. An acting force generatedby the cavitation acts on dirt so as to achieve the purpose of cleaning the pipeline.
