This invention is adapted to be embodied in a
deep well turbine pump of the type utilizing the
so-called “drip method” of delivering lubricant to
the line shaft enclosing tubing. The primary ob
ject of the invention is to provide means for auto
matically accumulating the lubricant which has .
traversed the line shaft enclosing tubing and the
line shaft bearings in the region of the impellers
of the pump out of contact with the water in
the well and in the pump. It is also an object to
provide means for automatically separating the
Water content of the lubricant which becomes
30 emulsified in its passage through the bearings,
and means for automatically returning the light
er components of the emulsion, or in other Words,
a clean lubricant, tothe surface for re-use. In
accomplishing this object it is a further object of

In connection with the accumulation and sep

is connected at its lower end to the bowl assembly
I5 in the well. The line shaft I4 extends through
a fitting generally indicated by reference numeral
2I at the top of the shaft enclosing tubing I1.
The iltting 2l provides a chamber 22 into which
the lubricant is fed drop by drop at a suflicient
rate to effectively lubricate the line shaft bear
sifled lubricant is given opportunity to separate,
that is, the oil separates from the water, while
it is in the lower chamber.
To permit passage of the lubricant accumu
lated in the, upper portion of the lower chamber
35 into the upper chamber 32 above it, the an
nular plate 3'I is provided with a threaded open
ing 3i’ in which is threaded a valve generally
indicated by reference numeral 45, which is de
ings. This lubricant is stored in a chamber 23
from which it is conducted to the chamber 22 by
means of a pipe 24 which includes a dripper valve .v signed to remain open only when the pressure 10

pressure in chamber 32. During the operation

of the pump the pressure in chamber 32 is kept
For accomplishing the objects of accumulat
ing and separating the component parts of the at a point substantially equal to the pressure of
15 water emulsifled lubricant which has traversed
the line shaft and line shaft bearings, a casing
23 is provided which extends above and prefer
ably below the bowl assembly I6». This casing
comprises an upper section 29 which is secured
in spaced relationship to the delivery pipe 20
the pumped ñuid inside the delivery conduit 23
by the provision of an opening or port 20' in the
delivery pipe. Thus during the operation of the
pump the pressure in chamber 32 is considerably
higher than the pressure in chamber 35 (Which
is at substantially well pressure) and thus keeps 20
by means of annular plate 30 to which it is weld
the valve 45 in closed position preventing the

upper section 29 is threaded on an annular plate
passage of any fluid from chamber 35 to cham
ber 32.
The upper end of the chamber 32 is provided
with a pipe 46 for delivering lubricant accumu 25
lated in the chamber 32 to the surface of the
ground. This pipe has been shown as discharg
ing into a container 41. A valve 46’ is posi
tioned at a suitable point in the pipe 45 for con
trolling passage of fluid therethrough. The con 30
tainer 41 is connected to the lubricant cham
ber 23 in the pump head assembly II by means
oi'. a pipe 48 suitably valved at 48’. The con
tainer 41 which is adapted to act as a separat

3I forms the lower closure of an upper chamber
32 formed by the casing section 23, delivery pipe
20, plate 3U and plate 3I. Threaded onto the
plate 3| is a lower section 34 which forms what
may be termed an open-ended lower chamber
35 surrounding ythe delivery pipe 20 and bowl
assembly I6 and the intake portions 35 of the
pump.
rI'his lower chamber 35 is in open com
munication with the well at its lower- end which
is designated by reference numeral 34’.
For the purpose of providing the conventional
communication from the interior of the shaft
enclosing tubing I1 to the chamber 35, a by-pass
31 is provided just below the line shaft bearing
I3. This by-pass is formed in a rib 33. Below
40 the bearing I9 an annular chamber 39 is pro
ing chamber is provided with an outlet pipe 49 35
at the bottom, which has a valve 49'. This pipe
is for the purpose of draining water from the
container.
`
In the operation of the device the lubricant is
fed into the top of the line shaft enclosing tub
vided with which the inlet of the by-pass 31 ing I1 and flows downwardly through bearings
vI3 and I9 and into the space 39, it becoming

It isgevident that with this `construction the pass 31 and into chamber 35 which is filled with
pressure in the chamber 35, since it is in open water due to the fact that it is in open commu
communication with the well, is substantially the nication with the Well at its lower end. The
same as the static head of the water in the well. entire casing 28, in this connection, is situated

When the pump is stopped the pressure in

In connection with the description _of the
shaft enclosing tubing by the pipe 24.
The construction >shown in. Fig. v5 permits a
chambers 32 and 35 it was pointed out that in
. closed automatic lubricating system after the
theordinary operation of deep well turbine
45
system has become saturated with lubricant.
When‘the pump is first installed and before such
time as suiiìcient lubricant has passed down
50 through the shaft enclosing tube and out into>
the separating chambers and is in condition to
be raised to the surface, the lubricant may be
suppliedto the top of the shaft enclosing tubing
by means of the pipe 55 communicating with the
55 reservoir 23. During this initial operation of the
`pump the valve 56 would be open and valve 52
closed. After the pump has been in operation
a sufficient time' for lubricant to-have passed
down the shaft enclosing tubing and accumu
60 latedin the upper portion of the top accumulator
chamber the valve 5.56 is closed andithe valve 52
pumps the level of the water standing in the
well would at all times be above the top of casing

thetwater level receding to a. point below the 50:
top of the casing 2B a stand pipe may be pro

be open at the top and thus provide a head of

preferably should be the height of the casing

and has threaded in its upper end another bear

tends downwardly through the apparatus and

Surrounding the line shaft 86 is the conventional

numeral |06 is provided with a very narrow pas

is formed of an upper section 90 and a lower
section 9|. An annular plate 92 divides the cas
ing 88 into an upper chamber 93 and lower cham
tured on the side opposite from the passageway
|06. With this construction the lubricant es
ber 84. This plate 92 is apertured at 92’ to ac
commodate a valve 95, similar to the valve shown
tion with the device shown in Fig. 2 and is pre
and described in connection with the preferred
form of the invention. Mounted in the upper end
of the chamber 93 is a pipe 91, similar to pipe
46 of the preferred form and adapted to be con
nected at the surface as shown in Fig. l. At the
lower end of the shaft enclosing tubing 81 are
apertures 81' which permit escape of accumu
lated lubricant into the chamber 94. The lubri
cant which has worked down through the shaft
enclosing tubing and bearings therein may thus
escape into chambers 94 through these openings
and accumulate in the upper portion of the
chamber just below the plate 92, dividing the
upper and lower chambers.
During the operation of the pump the pressure
in chamber 93 is maintained at substantially the
pressure of the pumped fluid by means of an
opening 90’ in the upper section 90 of the casing
89. As in the preferred form of the invention,
this pressure during operation of the pump serves
to keep the valve 95 in a closed position, thus
preventing any fluid from passing from chamber
84 to the chamber 93. When the operation of
the pump stops the pressure in chamber 93
drops to that of well pressure permitting valve
86 to open. This allows the entrapped accumu
lated lubricant in the upper portion of chamber
84 to pass through the valve into the chamber
45 83 where it accumulates in the upper portion
thereof.
'
It should be pointed out that at all times the
pressure in chamber 94 is substantially that of
the well pressure. This is accomplished by the
provision of a by-pass 98 which communicates
with the interior of the shaft enclosing tubing
and which is in open communication with the
well by virtue of the clearance existing between
the shaft and the bearing 84.

plate separating the upper and lower accumu
To take care of the possibility that the Water
in the well might drop below the casing 89 and
thus permit the lubricant from the shaft enclos
ing tubing to seep into thewell water, aÍ stand
pipe 99 is mounted on the lower portion of the
case 8| and extends upwardly a desirable dis
tance above the casing 89.
This stand-pipe is
adapted to be open to the well at the top and will
thus be filled when the water of the well is
above it. or by the high pressure leakage water
escaping through bearing 82. When the water
of the well recedes below the top of the stand
pipe, the stand-pipe retains a column of water
sufficient to counterbalance the fluid in cham
bers 93 and 94, and thereby prevent the escape
70 of any of the lubricant into the "water of the
well, since it is separated before it can leak
through port 98.
'
In Fig, 9 there is illustrated a modified form
of the invention which does not require a valve.
75 'I'he view shows a fragmentary section of the
capes into chamber |03 as described in connec
vented during operation of the pump from rising
into chamber |02 by the pressure of the water
in chamber |02 which is in open communication
with the fluid delivery conduit.
Thus, during
operation of the pump a slight stream of water 20
escapes through the passageway |06 into cham
ber |03, preventing passage of the lubricant up
wardly therethrough. The lubricant accumu
lates in the chamber |03 below the plate |05
until the pump is stopped, when it may ascend
into the upper chamber through the passage
|06. When the pump is started the lubricant
accumulated in the upper portion of the upper
chamber may then be delivered to the surface
of the ground in the manner above described
in connection with the other forms of the inven
tion. With this construction it is possible to
eliminate the valve employed between the two
chambers in the other forms of the device.
