Description

Изобретение относитс  к машиностроению и может быть использовано дл  гашени  колебаний трубопроводов в нефт ной, газовой, химической промышленности, теп- ловодоснабжении, энергетике и канализации .The invention relates to mechanical engineering and can be used to dampen vibrations of pipelines in the oil, gas, chemical industry, heat and water supply, energy and sewage.

Цель изобретени  - повышение эффективности устройства за счет демпфировани  набегающего потока окружающей среды (жидкости или газа).The purpose of the invention is to increase the efficiency of the device by damping the incident flow of the environment (liquid or gas).

На чертеже представлено устройство дл  гашени  энергии колебаний трубопровода.The drawing shows a device for quenching the vibrational energy of a pipeline.

Устройство закреплено на защищаемом трубопроводе 1 с зазором и содержит проницаемый дл  потока жидкости или газа цилиндрический сетчатый экран 2, нат нутый на кольца 3, которые установлены на трубопроводе 1 посредством распорок 4.The device is fixed on the protected pipeline 1 with a gap and contains a cylindrical mesh screen 2 permeable for the flow of liquid or gas, tensioned on the rings 3, which are mounted on the pipeline 1 by means of spacers 4.

Дл  уменьшени  прогиба цилиндрического сетчатого экрана 2 между кольцами 3To reduce the deflection of the cylindrical mesh screen 2 between the rings 3

использованы стрингеры 5. Ячейки б цилиндрического сетчатого экрана 2 могут быть выполнены, например, в форме квадрата . Сетчатый экран 2, кольца 3, распор- ки 4 и стрингеры 5 могут быть выполнены, например, из проволоки или прутьев.stringers 5 are used. Cells b of cylindrical mesh screen 2 can be made, for example, in the form of a square. Mesh screen 2, rings 3, spacers 4 and stringers 5 can be made, for example, from wire or rods.

Устройство работает следующим образом .The device works as follows.

Энерги  набегающего потока при прохождении через сетчатый экран 2 переходит в энергию мелких вихрей, которые обтекают трубопровод 1 с гораздо меньшей скоростью . С помощью распорок 4 устанавливаетс  необходима  дл  данного режима об- текани  величина зазора, что устран ет возможность образовани  крупных вихрей при обтекании трубопровода, вследствие чего колебани  его практически полностью гас тс .The energy of the oncoming flow when passing through the mesh screen 2 passes into the energy of small vortices that flow around the pipeline 1 at a much lower speed. With the help of spacers 4, the gap size necessary for this flow regime is established, which eliminates the possibility of the formation of large eddies in the flow around the pipeline, as a result of which its oscillations are almost completely extinguished.
