Definitions

  • the invention relates to spiral housings for fluid-flow machines such as centrifugal pumps, turbocompressors, axial compressors, turbines and the like, and their manufacture.
  • the spiral housing of fluid-flow machines serves to feed or discharge the conveying means or the drive medium and, depending on the type of device and its arrangement, also serves to convert the flow velocity of the fluid medium into pressure or vice versa.
  • pump housings with a surface that is as low in pores as possible must also be used.
  • the entire surface coming into contact with the product to be conveyed would have to be polished accordingly, which is extremely costly.
  • spiral housings have already been made from sheet metal using the deep-drawing process.
  • the formation of the spiral shape also poses special problems and requires complex tools.
  • the invention is accordingly based on the object of specifying a spiral housing for turbomachines and in particular centrifugal pumps which differs little from the predetermined, calculated contour, has a low-pore surface and is inexpensive to manufacture, and a corresponding production process.
  • the task is solved according to the requirements.
  • the spiral housing according to the invention consist of two semicircular housing halves with different radius in plan view, which are connected to each other so staggered along their diameter that they have a common tangent at one end of the common diameter. This results in an approximately spiral-shaped interior.
  • the offset at the other end of the common diameter is used to connect the corresponding pressure port.
  • the spiral housing according to the invention preferably consist of a rolled material, in particular rolled sheet metal, since these materials have a low-pore surface and at the same time are cheap and easy to process.
  • the spiral housing according to the invention can also consist of a suitable plastic material which can be glued or welded to the parting line.
  • the spiral housing according to the invention which preferably consist of rolled sheet metal, is also advantageously connected to one another at the joint of the two housing halves by welding.
  • the spiral housing shown in Fig. 1 consists of two approximately semicircular housing halves 1 and 2 with different radius, which are interconnected along their diameter D so that they have a common tangent T at one end E of the common diameter D.
  • Fig. 2 the two housing halves 1 and 2 are shown separately from one another, the edge being indicated.
  • the dashed lines correspond to the relative positioning in which the two halves are connected to one another in the finished volute casing.
  • the particular advantage of the method according to the invention is that inexpensive, easily accessible materials with favorable properties, in particular a low-pore surface, can be used and the manufacture is possible in a simple manner without special devices.
  • the spiral housing according to the invention does not necessarily have to be assembled from the two housing halves; alternatively, the volute casing can also be manufactured in one piece from suitable materials, for example using plastics.
  • the spiral housing according to the invention is basically suitable for all types of turbomachines and in particular for centrifugal pumps.
