Description

(54) УПЛОТНЕНИЕ ЛОПАТКИ НАПРАВЛЯЮЩЕГО АППАРАТА ГИДРОМАШИНЫ(54) GASKET SEAL OF HIDRO-MACHINE GUIDE EQUIPMENT

1one

Изобретение относитс  к гидромашиностроению и может быть использо- , вано в направл ющих аппаратах гид-i Ромашин.The invention relates to hydraulic engineering and can be used in guide-i devices of Romashin guides.

Известно уплотнение лопатки направл ющего аппарата гидромашины, содержащее уплотн ющий элемент из эластичного материала, размещенный в пазах одной из контактирующих деталей 1.It is known to seal a blade of a guide vane of a hydraulic machine, comprising a sealing element of an elastic material placed in the slots of one of the contacting parts 1.

Недостатком известной конструкции  вл етс  недостаточна  надежность при высоких напорах за счет невозможности надежного закреплени  уплотн ющего элемента, выполненного в виде шнура из эластичного материала.A disadvantage of the known construction is the lack of reliability at high pressures due to the impossibility of reliably securing the sealing element made in the form of a cord of elastic material.

Цель изобретени  - повышение надежности .The purpose of the invention is to increase reliability.

Указанна  цель достигаетс  тем, что уплотн ющий элемент выполнен составным из колец, контактирующих торцовыми поверхност ми.This goal is achieved by the fact that the sealing element is made of a composite of rings in contact with end surfaces.

На чертеже изображено уплотнение лопатки направл ющего аппарата.The drawing shows the seal of the guide vane.

Уплотнение лопатки направл ющего аппарата гидромашинн содержит уплотн ющий элемент, выполненный состац,ным из колец i, контактирующих TOt цовыми поверхност ми 2, кольца изготовлены из прочного материала, например нержавеющей стали.The sealing of the guide vane of the hydromachine unit consists of a sealing element made of a compound of rings i, contacting TOt with tary surfaces 2, the rings are made of durable material, for example stainless steel.

Уплотнение лопатки направл ющего аппарата гидромашины работает следующим образом.The compaction of the guide vane of the hydraulic machine works as follows.

При закрытии направл ющего аппа10 рата его лопатки поворачиваютс  до соприкосновени  с кольцами 1 уплотн ющего элемента, контактирующими торцовыми поверхност ми 2, которые более плотно прижимаютс  за счет по15 перечной деформации и взаимного перемещени  колец 1..,.When the guiding device is closed, its blades are rotated until they come into contact with the rings 1 of the sealing element, which contact the end surfaces 2, which are pressed more tightly due to the lateral deformation and mutual movement of the rings 1 ..,.

Использование предлагаемого уплот- нени  позвол ет повысить его надеж2Q ность и, таким образом, повысить межремонтный Ресурс работы уплотнени  и гидромашины в целом.The use of the proposed seal makes it possible to increase its reliability and, thus, to increase the overhaul life of the seal and the hydraulic machine as a whole.
