Abstract
Изобретение относитс к уплотнитель- ной технике и может быть использовано в уплотнительныхузлах насосов, работающих в коррозионных и абразивосодержащих средах. Цель изобретени - повышение надежности. Торцовое уплотнение содержит корпус 1, вращающеес 2 и невращающеес 3 уплотнительные кольца. Кольцо 2 аксиально подвижно. На валу жестко закреплен упругий элемент, выполненный в виде втулки 4, на торцовой поверхности которой имеютс выступы с отогнутыми пружинными лепестками 5, ориентированными по окружности втулки 4. Свободные концы лепестков 5 контактируют с нерабочей поверхностью уплотнитель- ного кольца. 4 ил.The invention relates to a sealing technique and can be used in sealing assemblies of pumps operating in corrosive and abrasive-containing environments. The purpose of the invention is to increase reliability. The mechanical seal comprises a housing 1, rotating 2 and non-rotating 3 sealing rings. Ring 2 is axially moveable. On the shaft there is a rigidly fixed elastic element made in the form of a sleeve 4, on the end surface of which there are protrusions with bent spring petals 5 oriented along the circumference of the sleeve 4. The free ends of the petals 5 contact the non-working surface of the sealing ring. 4 il.
