Description
ч. h
Изобретение относитс к трубопроводному транспорту жидкостей, преимущественно нефтепродуктов, и предназначено дл ремонта трубопровода путем тампонировани его течи ферромагнитной суспензией с воздействием на нее посто нным магнитным полем.The invention relates to pipeline transport of liquids, mainly petroleum products, and is intended to repair a pipeline by plugging its leakage with a ferromagnetic suspension with an exposure to a constant magnetic field.
Цель изобретени - устранение течи в стенке действующего трубопровода , за счет повышени механической прочности тампона и силы его сцеплени со стенкой трубопровода.The purpose of the invention is to eliminate leaks in the wall of the existing pipeline, by increasing the mechanical strength of the tampon and the strength of its adhesion to the pipe wall.
На чертеже приведена схема, по сн юща предлагаемый способ.The drawing is a diagram explaining the proposed method.
На место течи трубопровода 1 устанавливают посто нный магнит 2 с профилированной поверхностью, на которую предварительно нанос т тонким слоем ферромагнитную суспензию 3. Затем магнит придавливают, добива сь чтобы суспензи проникла в зазоры между трубопроводом и профилированно поверхностью магнита и частично в зону повреждени .A permanent magnet 2 with a profiled surface on which a ferromagnetic suspension 3 is preliminarily applied with a thin layer is installed in place of the pipeline 1 leakage. Then the magnet is pressed down until the suspension penetrates into the gaps between the pipeline and the magnet surface and partially in the damage zone.
Профилированную поверхность магнита 2 практически выполн ют в виде зубцов (или насечки), что обеспечивает создание градиентного (неоднородного ) магнитного пол , обеспечивающего необходимую герметизацию течи за счет повышени механической прочности тампона и силы сцеплени егоThe profiled surface of magnet 2 is practically made in the form of teeth (or notches), which provides a gradient (non-uniform) magnetic field that provides the necessary sealing of the leak by increasing the mechanical strength of the tampon and its adhesion strength.

со стенкой трубопровода. Это основано на эффекте поведени магнитных жидкостей в градиентном магнитном поле, согласно которому магнитна жидкость, вт гива сь областью сильного магнитного пол , уплотн етс и удерживаетс в этом состо нии пока на нее действует это поле.with the wall of the pipeline. This is based on the effect of the behavior of magnetic fluids in a gradient magnetic field, according to which the magnetic fluid, sucked in by a strong magnetic field, is compacted and held in this state while this field acts on it.
Дл ремонта, нефтепродуктопроводов целесообразно использовать магнитную суспензию на керосиновой основе, поскольку в этом случае нефтепродукт, смешива сь с родственным с ним керосином , также становитс магнитным и образует обратный валик, способствующий уплотнению тампона.In order to repair oil pipelines, it is advisable to use a kerosene-based magnetic suspension, since in this case the oil product, mixing with the related kerosene, also becomes magnetic and forms a back roller, which contributes to the compaction of the tampon.
