Description

Изобретение относится к турбомашиностроению, преимущественно к корпусам центробежных турбомашин.The invention relates to turbomachinery, mainly to the bodies of centrifugal turbomachines.

Наиболее, близким по технической сущности и достигаемому эффекту к изобретению является корпус центробежной турбомашины с фланцами, выполненными в зоне вертикального разъема и соединенными крепежными элементами между собой [1] .The closest in technical essence and the achieved effect to the invention is the body of a centrifugal turbomachine with flanges made in the vertical connector area and connected by fasteners to each other [1].

Однако поверхность разъема между фланцами не развита в радиальном направлении, что снижает надежность уплотнения частей корпуса.However, the surface of the connector between the flanges is not developed in the radial direction, which reduces the reliability of sealing parts of the housing.

Цель изобретения -г повышение КПД и надежности турбомашины. .The purpose of the invention is to increase the efficiency and reliability of a turbomachine. .

’ Указанная цель достигается тем, что фланцы расположены со стороны внутренней поверхности корпуса и плавно сопряжены с ней с образованием в плоскости разъема ребра.’This goal is achieved by the fact that the flanges are located on the side of the inner surface of the housing and smoothly mate with it with the formation in the plane of the connector ribs.

На чертеже изображен корпус центробежной турбомашины, поперечное сечение .The drawing shows the body of a centrifugal turbomachine, cross section.

Корпус центробежной турбомашины Д1меет фланцы 1 й 2, выполненные в зоне вертикального разъема 3 и соединенные между собой крепежными элементами 4. Фланцы 1 и 2 расположены со стороны внутренней поверхности 5 _; и 15 корпуса и плавно сопряжены с ней с образованием в плоскости разъема 3 ребра 6.The case of a centrifugal turbomachine D1 has flanges 1 and 2 made in the area of the vertical connector 3 and connected by fasteners 4. Flanges 1 and 2 are located on the side of the inner surface 5 _; and 15 of the housing and smoothly interfaced with it with the formation in the plane of the connector 3 ribs 6.

В данном корпусе происходит деление потоков газа ребром б на два вих· ревых потока, что способствует повышению КПД, а, кроме того, так как поверхность разъема достаточно развита в радиальном направлении, то повышается и надежность уплотнения стыка.In this case, gas flows are divided by edge b into two vortex flows, which increases the efficiency, and, in addition, since the surface of the connector is sufficiently developed in the radial direction, the reliability of the joint seal increases.

Claims

This invention relates to turbomachines, mainly to centrifugal turbomachine bodies. The closest to the technical essence and the achieved effect to the invention is the case of a centrifugal turbomachine with flanges made in the zone of the vertical connector and interconnected by fasteners between each other 1. However, the surface of the connector between the flanges is not developed in the radial direction, which reduces the reliability of the sealing of the housing parts. The purpose of the invention is to increase the efficiency and reliability of the turbomachine. . This goal is achieved by the fact that the flanges are located on the side of the inner surface of the body and smoothly mate with it to form an edge in the plane of the connector. In drawing 1 shows the body of the centrifugal turbomachine, the cross section. The case of the centrifugal turbomachine has flanges 1 and 2, made in the area of the vertical connector 3 and interconnected by fasteners 4. The flanges 1 and 2 are located on the side of the internal surface 5 of the body and smoothly mate with it 6 in the plane of the connector 3. In this case, the gas flows by the edge 6 into two vortex flows are divided, which contributes to an increase in efficiency, and, moreover, since the connector surface is sufficiently developed in the radial direction, the reliability of the joint sealing increases. Claims of the case of a centrifugal turbomachine with flanges made in the area of the vertical connector and interconnected fasteners, characterized in that, in order to improve efficiency and reliability of the turbomachine, the flanges are located on the side of the inner surface of the body and are smoothly matched with it to form rib connectors.
