Изобретение относитс к области уплотнительной техники.The invention relates to the field of sealing technology.
Известно торцовое уплотнение с регулируемой утечкой по авт. св. № 446965, в котором на поверхности трени одного из колец выполнены раздельные камеры, а на соответствующей ей поверхности другого кольца - подвод 1цие жидкость к паре трени каналы, причем число подвод щих каналов меньше числа камер, а выходные отверсти каналов расположены на том же диаметре, что и камеры 1.Known mechanical seal with adjustable leakage on author. St. No. 446965, in which separate chambers are made on the friction surface of one of the rings, and on the corresponding surface of the other ring there is a supply of liquid to the pair of friction channels, the number of supply channels is less than the number of chambers, and the outlet openings of the channels are located on the same diameter as the camera 1.
Недостатко.м известных уплотнений вл етс разрущеиие перемычек между камерами в результате кавитационпых влений в момент пересечепи кромок подвод щих каналов и раздельных камер.A disadvantage of known seals is the destruction of the bridges between the chambers as a result of cavitation phenomena at the time of intersection of the edges of the supply channels and the separate chambers.
Целью изобретени вл етс повышение падежности и долговечности торцового уплотнени .The aim of the invention is to increase the case and durability of the mechanical seal.
С этой целью раздельные камеры снабжены ответвлени ми, наибольший диаметр расположени которых больше диаметра расположени концов подвод щих каналов.For this purpose, the separate chambers are provided with branches, the largest diameter of the arrangement of which is larger than the diameter of the location of the ends of the feed channels.
На фиг. 1 изображено торцовое )шлотнение в продольном разрезе; на фиг. 2 - вид по А-А на фиг. 1; на фиг. 3 - вид по Б-Б на фиг. 1.FIG. 1 shows a face seal in longitudinal section; in fig. 2 is a view according to A-A in FIG. one; in fig. 3 is a view according to BB in FIG. one.
Уплотнение содержит корпус 1, крышку 2, вал 3 с закрепленным на нем вращающимс The seal includes a housing 1, a cover 2, a shaft 3 with a rotating fixed on it
кольцом 4. Ыевращающеес кольцо 5 установлено на выступе 6 крыщки 2, уплотнено резиновым кольцом 7, поджато пружиной 8 и зафиксировано от проворота штифтом 9. Pla поверхности трени кольца 5 выполнены разделительные камеры 10, отделенные друг от друга перемычками И. На поверхности кольца 4 выполнены подвод щие каналы 12. Камеры 10 снабжены ответвлени ми 13.ring 4. The rotary ring 5 is mounted on the ledge 6 of the lid 2, sealed with a rubber ring 7, compressed by a spring 8 and fixed from turning by a pin 9. Pla surface of the friction ring 5 is made of separation chambers 10, separated from each other by jumpers I. On the surface of the ring 4 are made feed channels 12. Chambers 10 are branched 13.
Уплотнение работает следующим образом.Seal works as follows.
Нри вращении вала 3 уплотн ема жидкость из полости В через подвод щие каналы 12, пересекающиес с ответвлени ми 13, поступает в эти ответвлени , а из них - в раздельные камеры 10. В результате последовательного подвода жидкости пульсирующее давление в камерах 10 создает гидростатическую силу.As the shaft 3 rotates, the condensed fluid from cavity B through inlet channels 12 intersecting with branches 13 enters these branches, and from them into separate chambers 10. As a result of the sequential supply of fluid, the pulsating pressure in chambers 10 creates hydrostatic force.
Так как при этом кромки подвод щих каналов 12 и камер 10 не пересекаютс друг с другом, то тем самым исключаютс кавитационное и эрозионное разрушени перемычек II между камерами 10. Имеющее место разрушение поверхностей трени колец 4 и 5 в зоне концевых частей ответвлений 13 не оказывает существенного вли ни на работу уплотнени , так как не нарушает последовательности взаимодействи камер 10 г. цодвод пдими каналами 12.Since the edges of the supply channels 12 and chambers 10 do not intersect with each other, cavitation and erosive destruction of jumpers II between chambers 10 are thus excluded. The friction surfaces of rings 4 and 5 that occur in the zone of the end portions of the branches 13 do not have significant influence on the work of compaction, since it does not disturb the sequence of interaction of chambers of 10 g.
