OILING- DEVICE FOR TURBINE-PUMPS.

Specification of Letters Patent.

Patented Aug. 2, 1921.

To @ZZ whom #may concern.'

Be it known that we, WILLIAM F. BAR- NICKOL and kALFRED W. ARCHER, citizens of the United States, residing at Stockton, in the county of- San Joaquin and StateV of California, have invented new-and useful Improvements in Oiling Devices for Turbine-Pumps, of which the following is specification.

This invention relates to a deep well turbine and particularly pertains to an oiling system therefor.

In that type of pump used within the casing of a deep well and operated from a remote power system above the ground, it is often a difficult problem'to provide adequatel lubrication for the driving shaft which extends down the well casing to the pump and the bearings of the kmoving parts of the pump itself.

It is the principal objectA of the present invention therefore, to provide simple means whereby a continuous flow of lubricant Vmay be established -to all of the bearing points of the shaft and pump irrespectiveof the remote position of vthese points in relation to the driving unit. Y

The present invention contemplates the use of a turbine pump formed in sections adapted to be lowered into a well casing and which pump is operated by a shaft connected at its upper end with a source of power supply, such as a vertical shaft, electric motor, said shaft being equipped with means whereby a continuous supply of lubricant mayl be conducted tothe various bearing points therealong and to the pump.

The invention consists of the parts and the construction, combination and arrange-A ment of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which:

elevation showing fragmentary portions of a pump andits power plant and their relation to the well casing.

Fig. 2 is an enlarged" view in central vertical section showing fragmentary parts of a well casing with the bearings of a pump and the oil conveying tube illustrated.

Fig. 3 is an enlarged fragmentary view in section showing the intake sleeve of the tubular shaft.

Referring more particularly to the drawings, 10 indicates a concrete base through which a well casing 11 extends. Mounted upon this base is an outlet block 12, having an angular eduction passageway 13 leading therefrom and in communication with the mouth of the casing 11. Thetop ofthe block 12 forms a suitable sub-frame for an electric motor 14, which motor is equipped with a vertical drive shaft 15. This drive shaft extends downwardly through a bearing 16, more clearly shown in Fig. 3, and within which bearing a stuffing gland 17 is formed.I Downwardly and inwardly extending passage-ways 18 are formed in the bearings 16 and communicate radially with a central lubricating chamber 19 surrounding the shaft l5. The bearing portion 16 extends through an oil reservoir 20 formed in the block 12 and which reservoir is provided with a feed pipe 21, leading to a mechanically or manually operated feed pump 22. The bottom wall of the reservoir 20 forms a guide bearing 23 through which the shaft 15 extends and by which it is supported for rotation while standing vertically.

A coupling sleeve 24 secures the lower end of the shaft 15 to a length 25 of the drive shaft which extends into the well and it will be understood that successive lengths may be disposed in longitudinal alinement and secured within the casing as dependent upon the depth of the well and the position of a pump 26 therein. The shaft section 15 is formed with the central longitudinal passage-way 27 as shown in Fig. 3. The upper end of this passage-way communicates with radial ducts 28 through which oil may flow from the surrounding chamber 19 into the y central passage-way 27, and then gravitate Figure 1 is a view in vertical section anddown--the interior of the shaft to be distributed in a manner to be hereinafter explained. l

The pump casing 11 is formed with companion flanges 29 which have outwardly flaring portions and between which bearing spiders 30 may be secured. It will be understood that these spiders will be interposed between the lengths of the pump casings,

- and it will be further seen by reference to and by which theopposite ends of the bearings are practicallyv sealed. Slip'ped over the caps 32 are conicalshields 84 which flare outwardly and are fitted with flanged portionscircumscribing the caps., These shields prevent foreign matter, such as sand `and dirt from )assinw into the bearin's and a t A :D Y

grinding them.

Each of the bushinoV longitudinal glands 36 are formed 1n the face of the shaft 25 and act as distribut'ers for lubricant passing outfrom theV of the invention as claimed.

' A lower length of shaft. extends through a-bearingspider 38, which is secured upon the upperV unit of the pump casing, said unit being` superimposed one upon the other and comprisingan outer volute casing` 39,

within which a runner 40 may move, These. runners are ofcourse secured to the shaftvv 25 and act to elevateliquid from the bottom A j. ofthewell tothe eduction passageway 13. The lower end of the shaft 25 lrests within Y `a bearing 4l which is equipped with a pressure chamber 42, permitting Vthe lubricant tor ,pass from the lower end of the shaft and .Y toV lubricate a bushing 42 whenthe pressure of the-lubricant within the shaft is in ex cess of a predeterminedamount.

`The feed pipe 2lisv provided with a T 43 to which an auxiliarylubricating tube 44V connected;V Thisl tube is fitted with a cutoff valveV 45, by which a flow of oil may be maintained tothe casing and directed down an oiling tube46.V Vllliis tube extends within the'casing and is formed Vin sections terminating fin the companionv flanges ofi Y each casing section. .The terminatingends 'of the tube 46 in thecompanion flanges are intended to .register with vertical ducts 47 Y vextending through the spider 13.. 'These ducts are in-v communicationrYwith radially vand'downwardly extending glands 4S within which the lubricant may be pocketed and Vdirected to the pump shaft. fore be evidentV that the two modes of com-V munication are provided, one carrying Vthe lubricant down the center of the pump shaft and the' other supplying it through the pump 46.

z as follows: The Vstructure is assembled VVas indicated by Fig. l in the drawing, after which the motor `14 may be placed inY action,` oil may then supply the cylinder 22 and be bearings 3l is fitted withlan inner bushing 85, while at theV point of therv It ywill `there- A Y Y.
