UNITED STATES PATENT OFFICE.
.ALADAR HOLLANDER, OF BERKELEY, CALIFORNIA, ASSIGNOR TO BYRON JACKSON PUMP MFG. 00., F BERKELEY, CALIFORNIA, A CORPORATION OF CALIFORNIA.
VERTICAL-PUMP MECHANISM.
Application filed May 17,
The pump of my invention is particularly adapted to the handling of chemical fluids and t0 the removing of acid or alkali solutions from tanks.
It is characterized by simplicity of construction and assembly and is such that the pump parts may be easily removed or replaced; combined with a security of operation and maintenance.
Other objects will be made clear by the specification below.
By referring to the accompanying drawing my invention will be made clear.
The pump here illustrated and disclosing my invention is adapted particularly to handling sulphuric acid or other corrosive chem-' ical fluids and the'parts are preferably all made of lead with the exception of the central shaft, key, washer and cap screw by which the runner is held in place.
In the drawing.
Figurel is a cross section through an acid tank employing the pump of my invention which is provided with conventional discharge connections.
Fig. 2 is a vertical cross section through the pump portions of Fig. 1 and on the line Ill-11 of Fig. .5.
Fig. 3 is a cross section of Fig. 2 on the line TIL-III.
Fig. 4 is a cross section of Fig. 2 on the line IV-IV.
Fig. 5 is a cross section of Fig. 2 on the line .v-v.
Throughout the figures similar numerals refer to identical parts.
An impeller hub is shownby the numeral 1 having the impeller blades 2 about its periphery, the impeller being fixed on the shaft 3 by the key 4, washer 5, and cap screw 6.
The washer and cap screw are sealed in the compartment 7 by the plate 8 which after the parts are assembled is soldered or welded integral with the runner hub thus closing the parts 5 and 6 from acid action.
The impeller is adapted to rotate in the pump casing 9 having the guide vanes 10 and dispersion cone 11.
The shaft 3 is protected by the lead tube 12 held in place by the collar 13 on one end and abutting at the other end against the runner hub 1, the said tube 12 thus rotating as an integral part with the shaft 3.
The cylindrical member 14 is provided 1926. Serial No. 109,484.
with a plurality of peripheral inlet openings around its lower portion between which are column members as 15, 16, by which it is integrally connected with and forms an extension of pump casing 9.
A plurality of guide vanes are shown at 17, 18 registering respectively with the col umn members 15, 16 and between these are a plurality of peripheral inlets to the casing 9 and impeller blades 2.
The inner wall of these inlet passages is provided by the downwardly directed conical member 19 which on its upper side is provided with lugs 20, 21 guided by the tracks 22, 23 and 24, 25 respectively, thus insuring the alignment of the vanes as and 17.
The conical member 19 is formed integral with or welded to'the tubular member 26 and may be lifted out of the structure. by drawing upward the member 26, at which time the lugs 20, 21 slide in the trackways- 22, 23 and 24, respectively, the said tracks being formed integral with the cylindrical member 14.
The pump is driven by the conventional motor 30 mounted thereabove and connected with the shaft 3.
An acid tank is shown at 34 having acid therein initially to the level 35.
The operation is as follows:
The parts are assembled by lowering the entire assembled pump as shown in Fig. 2, into the tank 34 so that the conical surface at 32 of the pump chamber 9 engages the inlet at the delivery pipe 33 making a taper joint therewith, the pump resting upon the tank floor and being supported therefrom as by the flange portion 36 on the lower end of the column 14.
The motor is supported thereabove and connected to drive the shaft 3. Upon operation the impeller blades 2 force the acid from the tank 34 through the delivery pipe 33.
The chemical action of the acid upon the parts of the pump, ommechanical injuries may make necessary the withdrawal of certain of the pump parts from time to time and their repair or replacement. This is accomplished without disturbing the cylindrical member 14, pump casing 9, or joint at 32. The shaft and its tube 12 together with the impeller 1, 2 and the conical member 19, the latter with its tubular portion the columns and 26, may all be entirely withdrawn from the cylindrical member 14, at which time the lugs 20, 21 travel up through the trackways 22, 23 and 24, 25; or the conical member 19 and tube 26 may be removed or relaced without disturbing the setting of the mpeller, shaft or the cylindrical member 14.
When the ump is stopped, the opening at 37 permits t e acid in the tank 34 to rise in the space 38 to equalize the pressure on both sides of the cylindrical member 14.
Reference is herein made to my co-pending application No. 106,340 filed May 3, 1926.
I claim:
