<p>The invention relates to a spiral casing (1) of a turbomachine, in particular a turbine, pump or pump turbine, which consists of a number of segments (2) which are arranged one behind another in the circumferential direction and are connected to one another at the respective end sides, having guide devices at the inlet to the support blades (3). It is characterized in that individual guide segments (9) are provided which are composed of plastic. Furthermore, the invention relates to a method for producing a spiral casing (1) of a turbomachine and the guide devices of the latter, wherein guide segments (9) are cast from plastic. As a result of the manufacture of individual guide segments (9) from plastic, simple adaptation to the changing contour of the spiral (1) and satisfactory and secure fastening can be ensured.</p> |
