Description
сторону спиральных направл ющих дл охвата последних.side of spiral guides to cover the latter.
В рабочем состо нии насос погружен з неоднородную гидромассу-пуль.пу со взвешенными в ней различного рода и размеров Включени ми.In working condition, the pump is immersed with non-uniform hydromass-pulp with suspended weights of various types and sizes in it.
Засасываемый насосом поток пульпы у входного патрубка 2 перемешиваетс отражательными лопатками 7, которые, враш,а сь, за)Кр)чивают поток и одновремеННО, благодар своему наклонному расположению, придают ему осевое направление, образу циркул цию по расшир ющейс спирали. Поэтому нриток пульпы происходит .00 стороны вершины конуса, образованного вращение м отражательных лопаток. Одновременно происходит ИНтенсивна разбивка .ко.мьев волокнистых сплетений -на фракции с измельчением длинных волокон.The pulp flow sucked up by the pump at the inlet nozzle 2 is mixed with reflective vanes 7, which, vrash, and for) turn off the flow and simultaneously, due to their inclined position, give it an axial direction, forming an expanding spiral. Therefore, the pulp flow occurs .00 sides of the top of the cone, formed by the rotation of the m reflective blades. At the same time, an intensive breakdown of .co.me of fibrous plexuses occurs - on a fraction with the grinding of long fibers.
Проход через решетку вращающихс отражательных лопаток 7, поток пульпы подвергаетс закручиванию. Спиральные направл ющие 3 выправл ют закрученный поток и, использу его инерцию, принудительно направл ют его через конфузор 2 к рабочему -колесу /.The passage through the lattice of the rotating reflective blades 7, the flow of pulp is subjected to twisting. The spiral guides 3 straighten the swirling flow and, using its inertia, force it through the confuser 2 to the working wheel /.
При перекачке густых пульп со слабовыраженной текучестью, дл поддержани непрерывности всасывающего потока на входе рабочего колеса создаетс дополнительный подпор пульпы к ра.бочему .колесу шнеком 4 в сочетании спиральных направл ющих 3 и конфузора входного патрубка 2. Открытый с баков шнек обеспечивает наиболее широкий фронт подступа густой пульпы. Поток , образованный спиральными направл ющими , совместно с «онфузорным .входом способствует заполнению шнека нульпой и осевому принудительному перемещению пульны к рабочему «олесу.When pumping thick slurries with poorly expressed fluidity, to maintain the suction flow continuity at the impeller inlet, additional pulp support is created for the working wheel by screw 4 in combination of spiral guides 3 and confuser of inlet 2. thick pulp. The stream formed by the spiral guides, together with the "onfusor" inlet, contributes to filling the auger with zero and axial forced movement of pulp to the working load.
Положительный эффект данного изобретени достигаетс спиральными направл ющими , выполненными в виде переменногоThe positive effect of the present invention is achieved by spiral guides, made in the form of alternating
диаметра, которые, взаимодейству с вращающимис органами, повышают интенсивность работы этих органов, улучщают забор и осевое перемещение пульпы. 5diameters, which, interacting with rotating organs, increase the intensity of work of these organs, improve the intake and axial movement of the pulp. five
