Specification of Letters Patent.
Patented Jan. 6, 1914'.
Application filed January 29, 1913. Serial No. 744,846.
To;all whom it may concem:
Be it known that I, Hans Goran, citizen of the Swiss Re ublic, residing at -Hardturmstrasse 19, urich, in the Swiss Repnlblic, haveinvented certain. new and use- Improvements in Centrifiitgal Pumps which the following is a specification.
. This invention consists in constructing at least one side of the 'rotor in centrifugal pumps or compressors in the form of a hyperboloid and securing to that side straight blades.
.As is well .known a hyperboloid is roduced by the rotation of a straight line a ut an axis without changing .its position with regard to that axis. By so choosing this position as to cause it to coincide with the position of the blades to be secured to the y rotor the great advantage is obtained of enabling straight blades to be used which are cheaper and easier ,to manufacture par-.
ticularly on a large scale than curved blades and which can be secured to the disk in a simpler and safer manner without necessitating the time-wasting operation involved in the usual setting and fitting. Straight bladeshave already been used, for instance,
in compressors, but'in this case the faces of the rotor destined to receive the blades had Curved rotor faces, how ever,'have .over straight facesrthe advantage of forming a better 'de for the air and of enabling a more avorable shape to be given to the rotor to counteract strains, and
I more particularly to. avoid thebending strains which are liable to occur in rotors with one-sided admission.
Thedrawing illustratesby way of ex ample therotorof a centrifugalcompressor with one-sided admission.
Figure 1 is a cross section, and Fig. 2 a front view of the rotor.
to be riveted to the'rotor a. In cross sec:
tion, as shown in Fig. 1, the blades should viewed in-lateral elevation; as shown in Fig. 2 they should form the an le 3/ with the radiusm so that in reality these blades are entirely oblique with regard to the axis a c. In precise co-incidence with this direction a straight line should now be rotated about the axis whereby the front profile of the rotor is determined and which fore assumes. the form of a 'yperboloid. Precisely registering with the position and direction of the eneratrix, the blades 1) to be riveted to tfi e rotor are then put in place. These blades need not all havethe same length, although as re ards the axis they must all have the same irection. The rear face of the rotor may likewise receive the form of a hyperboloid or that of any other rotary face or even be straight, if desired.
In the event of the rotor being subject .to admission on both sides, both faces are shaped as hyperboloids, so as to enable rofile thereform an angle a; with the axis'a a, while straight blades to be secured to both faces.
2. A rotor for centrifugal pumps, comprising in combination, a disk aving a lateralface constructed in the form of a hyperboloid, and straight blades secured to said face on lines coincident with the generatrix In testimony whereof I have aflixed my signature in presence of two witnesses. HANS GUYER.
