- ing parts comprising buckets or bladesv Patented Oct. 27. 1931 UNITED STATES orro RosENLocHER. or BERLIN, GERMANYj AssIGNoR'troGEN RAL ELECTRIC com- PANY, A. CORPORATION '"OF f' NEW YORK ELASTIC FLUID TURBINE -A'ND THE LIKE H Application filed November 15, 1929,Seria1 No.;4 07',51s, a d a Germany December 8,1928.
'lhepre'sent invention relates to rotating machines, such as elastic fluid turbines, ventilators, pumps, and the like, havingrotat through which the fluid current flows in an axial direction, andespecially to means for separating from the fluid current heavier particles being. carried along by-it. In-the case of elastic fluid turbines, the heavier particles may be in the form of drops of water which occurin the steam in the lower stages of the turbine; in the case of ventilators the heavier particles'maybe in the form of dust.
V or similar material; and in the case of pumps f [the particles maybe in the form of foreign material carried in the water or other liquid being pumped.
The ob'ect of my inventionis to provide an improved construction and arrangement for separatingsuch particles from the fluid current, and for aconsideration of what I bethat the invention is not necessarily limited thereto- In the drawings, Fig. -1 is a lon 'tudinal sectional View of a portion of a tur ine con- .struction embodying my invention; Fig. 2
is atransverse sectional'view of one of the buckets shown in Fig. 1; Fig.'3 is a transverse sectional view of a portion of a turbine structure taken on the line 33,Fig. 1, and Figs.
4' to-9 inclusive are detailed views of modifications. s h
Referringto the drawings, Figs. 1 to 3'inelusive, 1. indicates turbine buckets or blades carriedby a bucket wheel 2, which in turn ismounted on a turbine shaft (not shown) In Figs. 1 and 2, 3findicatesthe face of thehuckehand 4 indicates the back of the bucket.
' In advance of and beyond the bucket wheelare the usual nozzle diaphragms. 5 and 6,
which 'convey the "elastic fluid from one stage o'it'thdturbine 'to'the' next. 7"indicates the usualbu'cketcover'held inp'lace by'the tenons 8'. Itwill beund'erstoodthat the turbine may comprise a number of stages. The oneindicatedmay'xbe one 'of'thelater stages ofthe turbine, for it is here that moisture in'the elastic fluid is most frequently met with.
. According to the embodiment of my invention illustrated in Figs. 1 to3, for'separarating out the liquidparticles, I provide one or more radially extending passages '9 which extend along the backs 4 of the buckets. in proximity to 'the axialcenters or the buckets andto "permit offthe outward flow of "the liquid particles Iprovide passages 10in the bucket cover which communicate with the radial passages ,9. With this arrangement the liquid particles are caught in the passages 9. and are discharged radially outward .7 through tliepassages lO'l'by means of centrif ugaliorce. For removing the liquid particles, the surrounding casing is provided withanann'ular groove 11 which communicates with a chamber 1 2 which in'turn may have c'onnectedtofit a suitable drain pipe, (not shown); The annular groove llJmay be funnel shaped in cross section, as shown in Fig.1 and is provided with drain plates 11a inorderfthe better to catch and convey away the liquid particles. connection with the operation of thearrangeinent, it ,will'be understoodt'hat the particles to'be separated out move at a slower speed than. that of the medium passing throughithe buckets, and consequently the speed component of theparti'cles to be separatedmout; in the circumferential direction will .be considerably less than the circumfer- -.entifal speed of the buckets. Consequently, the'particles will be caught .by the backs of the'buoketsandwi-ll strike'the backs of the buckets at a high speed. i
Since the particles to be separated out, in
" addition tolheing subjectedito the axial aciceleration due to the medium passing through the. buckets, are exposed also to the centrifugal acceleration of the buckets, the upper ends of the backs of the bucket? are
