Abstract
The utility model relates to an unsmooth inner wall drag reduction pipeline, which is characterized by comprising a pipe wall and a drag reduction flower-shaped tooth unit on the inner wall of the pipe, wherein flower-shaped teeth of the drag reduction flower-shaped tooth unit on the inner wall of the pipe wall form an angle of 15-75 degrees with the inner wall of the pipe wall and form a barb shape with the inner wall of the pipe wall. Compared with the prior art, the improvement mode of the pipeline performance in the traditional sense is broken through, the inner wall of the pipeline is designed to be a bionic unsmooth surface, the drag reduction, anti-friction, anti-adhesion and anti-wear characteristics of the bionic unsmooth inner wall are fully utilized, and the characteristics of low energy consumption, low resistance, high self-cleaning, high wear resistance and high corrosion prevention of oil, water and gas delivery pipelines in a working state are realized.
Description
Technical field
The utility model relates to a kind of non-smooth inner wall drag reduction pipe.
Background technique
At present; Lot of domestic and foreign engineering field; All there are stream liquid/solid interface interaction effect in for example oil transportation, water delivery, gas pipeline, performances such as that pipeline need possess is self-cleaning, wear-resisting, anticorrosion, drag reduction; Existing inner-walls of duct is smooth structure, mainly relies on the improvement pipeline material at aspect of performances such as improving self-cleaning, wear-resisting, anticorrosion, drag reduction.
Summary of the invention
The purpose of the utility model provides a kind of structure of utilizing non-smooth inner wall, realizes low energy consumption, lower resistance, high self-cleaning, high abrasion, the non-smooth inner wall drag reduction pipe of high corrosion-resistant.
The purpose of the utility model realizes through following technological scheme:
Its characteristics of the utility model are: comprise the drag reduction flower tooth unit on tube wall and the inner tube wall, the colored tooth of the drag reduction flower tooth unit on the inwall of described tube wall becomes 15～75 degree angles with the internal face of tube wall, is reversed acanthoid with the inwall of tube wall.
Above-mentioned drag reduction flower tooth unit is matrix arrangement on the inwall of tube wall.
Above-mentioned drag reduction flower tooth unit is covered with on the inwall of tube wall.
Compared with prior art; The utility model has been broken through traditional tube performance mode of ameliorating; Inner-walls of duct is designed to bionic non-smooth surface; Make full use of drag reduction, antifriction, anti-adhesive, the abrasion resistant qualities of bionic, non-smooth inwall, realize low energy consumption, lower resistance, high self-cleaning, high abrasion, high corrosion-resistant characteristic during oil transportation, water delivery, gas pipeline are in working order.
