PEClFICATION forming part of. Letters latent No. 745,296, dated November 3, A1903.
Application filed March 30.1903. serial isaiasi. oro modem T0 Ii/,ZZ whom it may concern.-
Beit known that we, PAUL KUGEL and VIC-` TOR GELPKE, engineers, lcitizens of the Re#` `ityin centrifugal pumps and turbines the following points are necessary: rst, the regular course of the velocity of the moving liquid conforms to size and direction for the working wheel as well as for the guide-wheel second, the slowest possible change of the velocity of the flowing` liquid according to size and direction, and third, the smallest possible loss owing to space or passage between the working and guide wheels. The centrifugal high-'pressure pump forming the subject of the present application fulfils all these conditions.
The invention is illustrated in the accompanying drawings, in which- Figure 1 represents a central vertical section of a high-pressure pump of dierent steps; Fig. 2, a cross-section on line A B of Fig. l; Fig. 8, a section through one guide and one working wheel on a larger scale Fig. 4, a section on line C D E of Fig. 3; Fig. 5, a section on line F G H of Fig. 3; Figs. 6 and 7, an arrangement of wheels with intermittent blades or vanos. Figs. 8 and 9 show further forms of blades orvanes.
The pump consists of a number of guidewheels b d f h and b d'f' h', respectively,
and a number of Working wheels c c g t' and c' e g' fi', respectively. Each guide-wheel except the rst, h h', as well as each working wheel except the last, t i', contains a canal of the shape of an S, which is destined to the reception of guide-wheel blades or vanes.
The following is the mode of operation:
The liquid ows in an axial direction against the working wheel c and c', takes part through these vanes in the rotating movement, and derives therefrom a pressure which is nearly equal to the difference of the centrifugal power outside and inside. The liquid leaves the blades or vanes of the working wheel `in an axial movement in order to run over in an axial direction on the guide-wheel vanes. These guide-wheel vanes turn the direction andtheyvelocity of the promoting liquid in thegood' effect of the machine necessitates, Y first, that the regular course of thecurrent conforms to the size and direction. From Figs..A
3 to 5 can be seen that the working and guide wheel vanes extend through the whole S-like channel. The changes in velocity in the several `channel-cuts take place, therefore, in a steady way and without shock to the moving liquid. At the same time is prevented the rise of whirlpools and ensuing loss of work. This idea of continued vanes does not suler from the fact that they are interrupted on a short space, the interruption being such that acontinuance of the direction of the current is kept on. It is unimportant for the mode of operation of the machine whether the blades are placed at the entrance or exit in straight lines vertically, Fig. 6, or slanting toward the axis,Fig. 8, or end in sweeping curves, Fig. 9, as long as the continuation of the conduct is assured. Conforming to condition 2, a very slow shifting of the velocity of the promoting liquid is insured by spreading the vanes over the entire length of the channel, and therefore a minimum of high-pressure loss, which shows always by varying velocity. The curve is also very smooth, owing to the vanes being elongated, and the high-pressure loss is therefrom very small, which would be greater if short and therefore sharply-curved blades were used. From Figs. l to 3 may be further seen that owing to the chosen S form of the channel the curve radius Aat the passage from working wheel into guide-wheel and backis bigger than any other construction with exit vertical with the axis. Consequently there is in this invention a much smaller loss of high pressure through the curve, as is the case with centrifugal pumps having a radial exit.
Through this invention the loss of work through the space between working parts is produced, an exit of the promoting liquid being hindered through a single or repeated cylindrical twisting in of the working and guide wheel against each other. It is imma terial for these twistings whether the separation of the working or guide wheels falls acA curately in a plane vertical with the axis or in a conical plane whose generatrix is only little inclined toward foregoing plane. The use of the Working Wheels as balance-pistons comes of itself by this method of calking, as otherwise the pressure liquid introduced from outside could not enter into the channels of the working wheels.
As in the present construction the passage of the promoting liquid from working into guide-wheel happens in the direction of the axis, the diameter of the pressure-giving working wheel is nearly4 equal to the diameter of the covering-case. In consequence the pressure given to the promoting liquid through the function of the centrifugal power goes up to a maximum, and it is greater than on any other construction having no axial 'passage at equal conditions. Therein lies the great advantage that present invention can;
always be constructed smaller and lighterthan any other centrifugal pump with radial exita-t equal conditions. The combination of all points conducting to the fulfilling of above conditions assure to this machine great utility by simplest operation. The same advantageaccrues also to the machine When used as an air-forcing device.
We claimp A centrifugal pump comprising a casing, a shaft, guide -Wheels secured to the casing, working wheels on the shaft, the said guidewheels and the said working wheels each having approximately S-shaped channels with vanes therein, the `inlets and outlets from said channels being parallel with the axis of the shaft, substan tially as described.
In testimony whereof we have hereunto set our hands in presence of two subscribing witnesses.
