Abstract
Изобретение относитс к уплотнительной технике, в частности к уплотнени м штоков и плунжеров насосов. Целью изобретени вл етс повышение надежности уплотнени путем улучшени условий смазки уплотнительного элемента. Уплотнительный элемент 2 выполнен в виде втулки, представл ющей собой усеченные конусы разной высоты, обращенные друг к другу большими основани ми, с углами Α1 и Α2 при вершине и объединенные цилиндрической частью 5. Конус с большим углом Α2 и меньшей высотой расположен со стороны уплотн емого объема. Уплотнительный элемент размещен в камере 3, куда под давлением подаетс среда, прижимающа его к штоку 1. Форма уплотнительного элемента 2 обеспечивает треугольную эпюру контактного давлени , улучшающую услови смазки. 2 ил.The invention relates to a sealing technique, in particular to seals of pump rods and plungers. The aim of the invention is to improve the reliability of the seal by improving the lubrication conditions of the sealing element. The sealing element 2 is made in the form of a sleeve, which represents truncated cones of different heights facing each other with large bases, with angles Α 1 and Α 2 at the apex and joined by a cylindrical part 5. The cone with a large angle 2 and a smaller height is located side sealable volume. The sealing element is placed in the chamber 3, where the pressure is supplied under pressure, which presses it to the rod 1. The shape of the sealing element 2 provides a triangular plot of contact pressure, which improves lubrication conditions. 2 Il.
