Problems solved by technology

Coating drag reduction technology is to coat a layer of drag reduction coating on the inner surface of the pipeline, but there is a large turbulent pulsation resistance, and the drag reduction ability is very weak
The drag reduction of drag reducer is simpler than that of coating, but the drag reducer is consumed quickly and needs to be replenished continuously, especially for pipelines that need to be transported for a long time, because a large amount of drag reducer is required, the economic benefit is not good obvious
[0003] Therefore, there is currently no very effective drag reduction technology applied to oil and gas pipelines, and the bionic drag reduction surface fully imitates the surface drag reduction structure of biological living habits, which can reduce oil and gas transportation resistance

Abstract

The invention provides a pipeline inner wall bionic groove surface machining device and a machining method thereof. The device comprises a drive mechanism used for providing drive force, a traveling mechanism used for supporting the inner wall face of a pipeline, a machining mechanism used for machining a bionic groove in the inner wall of the machined pipeline, and a controller. The drive mechanism is installed on the traveling mechanism through bolts. The machining mechanism is fixedly connected with the traveling mechanism through bolts. The drive mechanism and the machining mechanism are electrically connected with corresponding control ends of the controller. The method comprises the steps that according to the diameter of the pipeline needing to be machined, a front and back traveling unit is adjusted in a rotating manner, after the machining mechanism is moved to the position, to be machined, on the inner wall of the pipeline, the traveling unit stops moving and presses the inner wall of the pipeline, the cutter position of the machining mechanism is adjusted, and the groove in the inner wall of the pipeline begins to be machined. The device has the beneficial effects that tangential counter force borne by three tools in the cutting machining process can be offset, thus, bending deformation and torsional deformation are avoided, and meanwhile the device is high in precision, simple in structure and easy to operate.

Description

technical field [0001] The invention relates to a surface processing device and method for bionic grooves on the inner wall of a pipeline. Background technique [0002] The pipeline transportation of fuels such as oil and natural gas will generate relatively large transportation resistance, thereby reducing the transportation efficiency. At present, coating drag reduction and adding polymer drag reducer are mainly applied to a small number of pipelines. Coating drag reduction technology is to coat a layer of drag reduction coating on the inner surface of the pipeline, but there is a large turbulent pulsation resistance, and the drag reduction ability is very weak. The drag reduction of drag reducer is simpler than that of coating, but the drag reducer is consumed quickly and needs to be replenished continuously, especially for pipelines that need to be transported for a long time, because a large amount of drag reducer is required, the economic benefit is not good obvious....
