Embodiment Construction

[0023] exist figure 1 The turbomachine 10 shown in is a turbocharger. In a rotor housing 11 , a rotor 11 driven by the hot exhaust gas rotates about an axle 12 . In order to minimize the risk to surrounding equipment and personnel during a rupture of the rotor 11 , a rupture protection device according to the invention is arranged around the rotor housing 11 . The shatter protection is formed by the shatter protection element 1 , which surrounds the rotor 13 in its circumferential direction around the wheel shaft 12 and in the process also encloses the rotor housing 11 in its interior. In the longitudinal direction of the wheel shaft 12 , which lies perpendicular to the plane presented, the rupture protection element 1 extends over the entire width of the rotor 13 in the longitudinal direction of the wheel shaft 12 .

[0024] For example, when a blade of the rotor 13 breaks, at least a part of the blade is thrown against the rotor housing 11 , which is mainly embodied as a c...

Abstract

The present invention relates to a burst protection device for a turbo machine having a rotor housing, which includes an axle and a rotor that is rotatably mounted about the axle in the rotor housing.The burst protection device surrounds the rotor housing at least in the region of the rotor in a circumferential direction of the rotor and is formed in one part of at least one burst protection element. The at least one burst protection element is a material having an elongation at break of at least 30%.

Description

technical field [0001] The invention relates to a rupture protection device for a turbomachine, preferably a turbomachine or a compressor. Background technique [0002] In the prior art, different rupture protection devices for turbomachines are known. In the event of a rupture of a part of a turbomachine, such as, for example, during a rupture of a wheel or rotor of a turbomachine, the rupture protection device is used to catch flying parts so that these parts do not pose any danger to personnel and do not damage adjacent machinery. However, the fracture protection devices known in the prior art are generally expensive to produce and very heavy due to their construction and their materials. Contents of the invention [0003] It is therefore the object on which the present invention is based to provide an advantageous and light-weight rupture protection device for a turbomachine, which at the same time offers a high degree of protection against flying parts in the event o...
