Speoioatlon of Letters Patent. i Application led June 19,- 1911. Serial 170.634,06,
To all whom it. mag/concern.' y v Be it known ythat I, FRITZ S'rRoHBAoH, a subject of the King of Prussia," residing at Charlottenburg,v Germany, have invented certain new and useful Improvements in Centrifugal Pumps or Compressors, of which the following is a specification.`
The present invention relates to centrifugal pumps or compressors of the so-called throwing type, and has for its object to improve their construction and operation, particular reference being made to the means for separating air and other gases from the throwing water after it leaves the pump proper and before it enters and is acted upon by the cooler.
In the accompanying drawing, which illustrates one of the embodiments of my 1n.
vention, Figure 1 is a vertical section of a centrifugal pump or compressor, and Fig. 2 is a detailed view showing the'arrangement of certain of the passages for permitting air and other gases to pass from the cooler to the separating chamber.
1 indicates the base of the apparatus which is providedwith a vertically disposed hollow column 2 that contains the cooler 3, the latter being'composed of a plurality of pipes or conduits through which circulating water or other cooling medium flows. .The upper end of the column is enlarged to form a support 4 for the casing or top part 5 of the pump.
6 indicates the pump impeller which is mounted on a vertical shaft 7 that is driven by an elastic fluid turbine or otherv motor 8.
The impeller is provided with vanes 9 that receive throwing water from the suctionchamber 10 and discharge it outwardly through a stationary4 directing wheel or annulus 11, the latter comprising a plurality of passages 12 through which the throwing water and air and gases How. Between these passages are fixed vanes'13. The mixture of throwing water and gases discharged by the annulus is received in the receptacle 14, the latter being provided with an inwardly inclined wall 15 to change the direction of flow of the fluid thereby causing4 thev water and air separate. The 'cover is an\d,other gases'from a condenser or'other vessel to be evacuated. vThe lower-end of 'chamber 19vis open and is indirect communication with the inlet side of the annumay be controlled by a valve in the ordinary manner. v
22 indicates an outlet for the excess water due to the condensation of steam and may be controlled by a valve in the ordinary manner. o
As the throwing water is discharged from thel annulus l11 its direction of flow is changed bythe wall 15. It then enters the separat-ing chamber 16 where the principal passes by'the conduit 17 into the receiving chamber 18, and thence vliows to the bottom of the cooler 3 and rises by the passage 23 to the suction chamber 10 of the impeller. The throwing water leaving-the separating chamber 16 and entering the receiving chamber 18 carries more or less air and uncondensed gases which must be removed if the best results are to be obtained from the other gases from the throwing water, I provide one or more passages or conduits that convey said air and gases from the receiving chamber 18 into the separating chamber 16 at a point above the level of the throwing water. In the present illustration of is provided forthis purpose: 24, Fig. 2, indicates an opening in the wall that supports the annulus and which communicates with conduitsl or passages 25 that extend through the top and bottom walls of the annulus, and also through the fixed vanes 13 thereof. These conduits or passages communicate with a chamber 26 that is formed between `the wall of the supply chamber 19 and an annular shield. The saidshield comprises an annular inclined wall 27 which at its lower end rests on the top of the annulus and at its upper end supports the cylinder 28. The upper end of the cylinder is provided with an outwardly extending flanged member 29 which is located above the level of the water in th Patented Jan. 2,1912.
provided with a supply chamber 19 that hasv an lnlet conduit 20, the latter receiving air cooler and pump. To separate this air or' lus l1. flhe separating chamber 16 is prof vided with an outlet conduit 21 for the escape of a1r and other gases. Thislconduitportion vof the air escapes. The water then this invention, the following arrangement l separating chamber. This means that there is a direct escape for any air or other gas that may be carried through the conduit 17 into the chamber 18 with the throwing liquid. The air fro-inthe chamber 18 flows upwardly between the shield and the wall of the chamber 19 into the separating chamber and escapes through the outlet pipe 21, together with the air which is separated from the liquid in the chamber 16.
In accordance with the provisions of the patent statutes, I .have described the principle of operation of my invention together with-the apparatus which I now consider to represent the best embodiment thereof; but I desire to have it-understood that the apparatus shown is only illustrative, and that the invention can be carried out by other means.
What I claim as new and desire to secure by Letters Patent ofthe United States, is,-
1'. In a pump of the character described, the combination of a casing, an impeller'located therein, an annulus surrounding the impeller and receiving the fluid discharged thereby, a chamber communicating with the inlet side of the annulus, a separatlng chamber in which the gas is'separated from the mixture discharged by the annulus, a cooler that receives liquid mixed with some gas from said chamber and after cooling the liquid delivers. it to the suction side of the impeller, and conduit means which receive gas V from' the liquid after it enters the cooler and conveys it to said separating chamber.
2. In a pump of the character described, the combination of a casing, an impeller located therein, an annulus surrounding the impeller and receiving the fluid discharged thereby, a chamber communicating with the inlet side of the annulus, a separating chamber in which gas is separated from the mixture discharged by the annulus, a cooler that receives liquid mixed with some gas from the chamber and after cooling the liquid delivers it to the suction side of the impeller, and a conduit which extends through the annulus and establishes communication between the cooler and said separating chamber.
3. In a pump of the character described, the combination of a casing, an impeller located therein and occupying a horizontal plane, an annulus surrounding the impeller and receivin'g the iuid discharged thereby, a chamber located above the im eller and communicating with the inlet si e of the annulus, a separating chamber located above the annulus in -which gas separates from thel mixture discharged by the annulus, a cooler located below the im eller and annulus` which receives the li u1d mixed with some gas and after cooling t e liquid delivers it to the suction 'side .of the impeller, and conduit means that extend through the annulus and establish communication between a chamber in the upper end of the said cooler and said separating chamber.
