INVENTOR. 7mm/L fi im W A TTORNEY Patented Feb.` 3, 1931 PATENT OFFICE EMANUEL A. SMITH, F HAYWABD, GAIIFORNIL rUurrNe DEVICE Applicatinn led .Tune 18, 1928. Serial No. 286,093.
The invent-ion relates to a Imethod and apparatus for increasing the ein'ciency. and range of use of suction pumps for liquids.
An object of the invention is. to provide a 6 method whereby a suction pump may be utilized in raising a liquid through an appreciably greater height than the atmospheric lift height for the liquid.
Another object of the invention is to provide a device of the character described in which the liquid being lifted is itself utilized i'n the carrying out of the method.
A further object of the invention is to provide a device of the character described which is articularly applicable for use with a centri ug'al pump andvother pumps arranged for eifectin a continuous flow.
A still further o ject of the invention is yto provide particularly simple and effective apparatus for carrying out the invention.-
he' invention possesses other objects and features of advantage, some of which, with the foregoing, will be set forth in the following |description of the preferred form ofthe invention which is illustrated in the .drawings accompanying and forming part of the specification. It iste be understood, however, that variations in the showing made by the said drawin s and descriptions may be ado ted within tlie scope of the invention as set orth in the claim. Referring to said drawin Figure 1 is a side view o an installation embodying the invention.
Figure 2 is an enlarged sectional view of a portion of the apparatus used.
As herewith particularly illustrated, the device of my invention is applied in connection witha centrifugal pump 3 of a usual type having a discharge pipe 4 and a suction pipe 6. The suction pipe 6 extends downwardly through a well caslng'? and into the water at 4the lower end thereof and is provided at its bottom end with a suitable one-way vfoot valvel 8 through which the water from thev well is arranged to be drawn `into the suction pipe 4 is arrange to take place under pressure into a stand-.pipe or tank 9 preferably 5 having its outlet 11 above the top of the Y tank 9, and a pipe. Discharge from the pump for a purpose to be hereinafter brought out. f
An injector 13 is interposed in the suction pipe 6 above and adjacent the foot valve .8,
.and said injector is connected with the pump discharge pipe v4 by means of a pipe 14 and a T 16, the pipe 14 preferably being disposed in the casing 7 beside the pipe 6 and of somewhat smaller size than is the latter pipe. A regulating valve 17 is provided in the discharge pipe 4 between the T 16 and lpressure gage 18 is preferably connected wit the discharge pipe between the T and the pump. The injector 13 is arranged to discharge upwardl in the ipe jwhereby its effect is arrange to be a ded to the suction created by the pump in the pipe.
With the present arrangement, when the pump 3 is operating to discharge water into the tank 9 under pressure, a certain portion of the water passing through the discharge pipe 4 will be diverted into the pipe 14 and so through the injector 13 and bac into the` suction pipe 6, the dischargeof this re-circulated water from the injector producing an injector effect which is operative indepen ently of and in addition to the suction 1n the pipe 6 for drawing water through the foot. valve 8. The amount it will now be clear, is arran ed to be controlled b a regulation of the ischarge pressure in t e pipe 4 by means of the valve 17,
the-discharge opening of the injector being s constant.
As is well known, the maximum suction lift of a pump is limited by the density and tem rature of a liquid to be raised and the of water recirculated, 9
eiiiciency of the pump, to a value usuallly w somewhat below thirty feet, with the resu that suction pumps at the ground surface are only effective for shallow wells. Yet owing to. the higher. eiliciencies of continuous flow pumps, and particularly centrifugal pum s, such are used wherever possible, and in t e case of deeper wells it is a common practice to provide a pump well for disposing a pump,
within its suction lift distance 0f thelttir in the well. In accordnmlwth .thp'l''li-. inventidn, however, e pumpmly be used for drawing water from a well considerably exceeding in depth the suction lift limit without necessitating a disposal of the pumpbelow the ground level, it being merely necessary to appropriately adjust the discharge of the inj'ectonfor effecting a raising of the water Within the suction lift range of the pump. Since in the present method, some ofthe pumped liquid is itself utilized for effecting the desired injection of water into the suction pipe, the pump is the only part of the device which requires power for its operation, for the discharge pressure -created by it is utilized in effecting the in-- jector operation, and a minimum of equipment is thus required.
By way of example as to the operation of the apparatus, it is found that water may be raised from a seventy foot well when the gage 18 registers about thirty pounds. above atmospheric pressure. It will, of course, be obvious that a balanced adjustment of the valve 17 is preferably made for the lowest possible operating pressure to effect a maximum delivery of water to the tank. Since the injector circuit is in constant communication with the tank 9 through the pipe 4, and the tank discharges above the pump, the pumping circuit will always be primed for a starting of the pump. lVhen the pump is to be started, the valve 17 would be closed Somewhat 'to increase the discharge pressure until the flow is established.
The Water operated injector 8, it will now be noted, has been particularly designed for use with the present system and apparatus,
an important feature thereof being its extreme simplicity of structure. As disclosed, the injector comprises a generally tubular body member 21 carrying the foot valve 8 at the lower end thereof and arranged to be secured to the pipe 6 by means of a member 22 formed generally as a pipe union of a usual structure. Extending into the body 21 from a side thereof is a conduit 23, said conduit terminating in a contracted jet nozzle 24 directed axially upwardly through the passage 26 of the body 21, which passage is preferably enlarged between the ends thereof whereby the ow of incoming water about the nozzle 24 is facilitated. Preferably, and as shown, the conduit 23 and nozzle 24 form integral portions of the body member 21 and a threaded o ening is provided at the outer endof the con uit passage for the recepjtion of the pipe 14.,
The"innember 22, it is noted, comprises collars 27 and 28 arranged for threaded engagement with the lower end of the pipe 6 and the upper end ofthe body 21, respectively, and these collars are provided with outwardlyl extending annular flanges 29 and 31 at t eir opposed ends. A sleeve member 32 is utilized for drawing the collars 27 and 28 toward each other, lsaid sleeve being arranged day of May, 1928.
to threadedly engage one of the collar flanges and having an inwardly extending flange 33 for engagement behind the other collar flangchas shown, the sleeve vflange 33 is engaged behind the cQllar flange `29 and is threadedly engaged with the collar flange 31 whereby the collars may be releasably clamped together in axial alignment.
It will now be noted that the injector structure also includes va'discharge tube 34 of less diameter than the bore of the suction pipe 6 v and having coterminous and generally conically tapered bore portions 36 and37 defined thereinV with their larger ends at the extremities of the tube. The bore portion 36, it is noted, extends for the greater part of the length of the tube whereby the inclination of the bore walls to the tube axis is relatively small, while the walls of the bore portion 37 make an angle of about forty-five degrees with the bore axis. Formed at the i11- ner end of the tube 34 is an annular flange 38, said flange being arranged for disposal between the opposed ends of the collars 27 and 28 whereby the tube may be engaged and held in fixed coaxial relation to the pipe 4 and jet nozzle 24.
Preferably, and as shown, more or less resilient gaskets 39 arel inserted between the tube flange 38 and the opposed ends of the collars 27 and 28, it now being clear that the tube 34 is arranged to be secured in place by and upon' a screwing up of the sleeve 32k on the threads of the collar flange 31.V By
varyinglthe thickness of the gaskets 39, ad-
justment of the relation of the inner end of the tube 34 to the tip of the nozzle 24 may be effected, it being noted that said end and tip should be in substantially coplanar relation as shown, some adjustment of their relation being usually necessary for different lifts. For deeper wells, the tip of nozzle 24 is adjusted to lie well within the bore portion 37 of the discharge nozzle 34.
The injector unit now described, it will be noted, has been found particularly satisfactory and efficient under a wide variety of conditions of use. And, furthermore, the simplicity of structure and ease of assembly are also noteworthy features of the device.
l claim: v
In a pump, a pipe through which li uid is pumped, a collar surrounding an en of said pipe, a discharge tubevwithin the pipe, another pipe, a collar on one end of the second pipe, an annular flange onf/the tube engaged between said collars, a coupling'sleev'e surrounding and detachably joining said col'- lars, and an injector nozzle' inthe ksecond' named pipe and arranged fo discharge into said tube.
1n testimony whereof, I have hereunto set my hand at` Oakland, California, this 28th EMANEL A. sMrrH.
