Abstract
Изобретение относитс к машиностроению и может быть использовано дл гашени в гидравлических системах пульсаций давлени среды и гидравлических ударов. Цель изобретени - повышение эффективности гашени колебаний давлени . При работе гасител поток рабочей среды, например пульпы, подаетс центробежным насосом 2 по магистрали 1 в корпус 4. при этом происходит закручивание струи по винтовой траектории за счет выполнени подвод щего патрубка 6 тангенциально к корпусу 4 и под углом к днищу 5. Затем поток поступает в коническую часть корпуса 4 и попадает на неподвижно закрепленное шнековое колесо 8 с втулкой 10 и лопатками 9 переменного шага и далее к отвод щему патрубку 7 и плунжерному насосу 3. Имеющиес в потоке рабочей среды колебани давлени гас тс за счет взаимодействи с элементами конструкции гасител , а именно корпуса 4, колеса 8, установленного с зазором относительно патрубка 7, лопаток 9, втулки 10 и пониженной плотностью закрученного потока по радиусу корпуса 4, что обеспечивает повышение эффективности гашени пульсаций давлени рабочей среды . 2 ил. (Л СThe invention relates to mechanical engineering and can be used for damping in hydraulic systems of fluid pressure pulsations and hydraulic shocks. The purpose of the invention is to increase the efficiency of damping pressure fluctuations. When the extinguisher operates, the flow of the working medium, for example, pulp, is supplied by the centrifugal pump 2 through line 1 to the casing 4. At the same time, the jet is twisted along a helical path by making the inlet 6 tangentially to the body 4 and at an angle to the bottom 5. Then the flow enters into the conical part of the housing 4 and falls on a fixed screw screw 8 with a sleeve 10 and variable pitch blades 9 and further to the outlet nipple 7 and the plunger pump 3. The pressure fluctuations present in the flow of the working medium are extinguished by interaction with the design elements of the damper, namely the body 4, the wheel 8 installed with a gap relative to the pipe 7, the blades 9, the sleeve 10 and the reduced density of swirling flow along the radius of the body 4, which improves the efficiency of damping the pressure pulsations of the working medium. 2 Il.
