Description
При вращении вала 1 с угловой скоростью О) совместно с ним вращаетс втулка 2 с установленным в ее проточке пористым уплотнительным элементом 4. При этом, в св зи с установкой уплотнительного элемента 4 в проточке втулки 2 с нат гом, контактом скольжени будет поверхность Ь шейки а корпуса 5. Распыленна жидкость, наход ща с в полости V, попадает на поверхность скольжени Ь, движетс по ней н впитываетс пористым уплотнительным элементом 4. Поскольку элемент 4 вращаетс с угловой скоростью со, эту же угловую скорость приобретает и впитанна им жидкость. Под действием центробежной силы жидкость принудительно движетс в радиальном направлении к днищу проточки втулки 2, откуда через отверсти 6 выбрасываетс обратно в полость V.When the shaft 1 rotates at an angular speed O), the sleeve 2 rotates with the porous sealing element 4 installed in its groove. In connection with the installation of the sealing element 4 in the groove of the sleeve 2 with tension, the sliding contact will be the b surface of the neck The housing 5. The sprayed fluid, which is located in the cavity V, hits the sliding surface B, moves along it, and is absorbed by the porous sealing element 4. Since element 4 rotates with angular velocity c, the same angular velocity is absorbed and absorbed. m liquid. Under the action of centrifugal force, the liquid forcibly moves in the radial direction to the bottom of the groove of the sleeve 2, from where it is thrown back through the holes 6 into the cavity V.
Предлагаема конструкци уплотнени обеспечивает повышение уплотн ющего эффекта, предотвраща утечку жидкостиThe proposed seal design enhances the sealing effect, preventing leakage of fluid.
ИЗ уплотн емой полости без нарушени проницаемости уплотнени дл газа, т. е. оно одновременно выполн ет и функцию воздушника (сапуна).From the cavity to be sealed without disturbing the permeability of the gas seal, i.e., it simultaneously performs the function of the vent (breather).
