Patented Aug. 30, 1932 PATENT- OFFICE GEORGE S. COATS, F VISA-LIA, CALIFORNIA DEEP-WELL runrrlvn PUMP Application filed November 5, 1930. Serial No. 493,664.
My invention relates to improvements in deep-well turbine pumps, and it consists 1n the combinations, constructions and arrangements hereinafter described and claimed.
An object of my invention is to provide a deep-well turbine pump in which the propeller is designed to rotate at a high speed, the propeller carrying blades which are inclined oppositely to blades carried by the It bowl housing the impeller. The high speed of the impeller throws thewater against the bowl blades by centrifugal force, and this materially increases the efficiency of the I pump.
he device may be used submerged in the well water, or it may be disposed at the top of the well and function like a turbine in sucking the water up from the well.
. Each device will lift the water approximately fifteen feet, and therefore if it is desired to raise water sixty feet, four devices can be placed one above the other and all be actuated by the same-shaft. The impeller of each device is placed a short distance away from the adjacent propellers, and the inclined vanes in each device are gradually curved so as to extend longitudinally of the well and thus direct the water into the next higher impeller without whirling the water.
In this way the next higher impeller can act upon the water more efficiently than is possible when the water is whirling as it enters the impeller.
A further object of my invention is to provide a device of the type described which is extremely simple in construction and which is durable and eflicient for the purpose intended. v
My invention is illustrated in the accompanying drawings, in which:
Figure 1 is a vertical section through the device showing the impeller in elevation,
Figure 2 is a bottom plan view of the device,
Figure 3 is a top plan view of the device,
and
Figure 1 is a section along the line 14 of Figure 3.
In carrying out my invention I provide a casing 1 which is designed to enter a well and to be lowered to the desired place. The casing has a bowl portion indicated generally at 2 in which a plurality of inwardly extending and inclined blades 3 are disposed. The shape of these blades is clearly shown in Figure 4.
Within the bowl 2 I rota'tably mount an impeller 4 that has vanes 5 inclined in an opposite direction to that of the vanes 3. I have further found that the device will operate more efliciently when the blades on the impeller are inclined from five to ten degrees more sharply than the blades on the bowl. In other words, the blades 3 are more horizontal than the blades or vanes 5.
The impeller 4: has a conical-shaped hub 6 as clearly shown in Figures 1 and 2, and the vanes or blades 5 will therefore be wider at their bottoms than at their tops. This pros vides a larger water inlet at the bottom and 7 a smaller water outlet at the top,fwhich results in the water being speeded up as it is forced through by the impeller.
The impeller 4 is secured to a driving shaft 7, and this shaft extends to the top of the well where it is connected to a power source (not shown) such as a motor or engine. The shaft 7 rotates in a bearing 8 which in turn is disposed in an inner casing 9. The inner casing is connected to the outer casing 1 by alter- 8Q nate vanes 3 that are extended above the bowl 2 as indicated at 10 and shown in Figure 4. The vanes 3 which extend above the bowl 2 are gradually curved so as to be extended in avertical direction near the tops of the portions 10. These portions 10 direct the water vertically and stop it from whirling.
If more than one pump is used, the impeller 4 of the next pump is placed at the top of the portions 10 and receives the water from the channels formed by the portions 10 and the casing 1. A new set of vanes 3 are associated with the new impeller, and they will function in the same manner .as the impeller 4, and vanes 3 and 5.
It will be noted from Figure 4 that the por tions 10 of the blades 3 are wider at a point directly above the top of the hub 6. The wider portions 10 extend over the blades or vanes 5 and receive the water from the vanes 5. 100
From the foregoing description of the various parts of the device, the operation thereof may be readily understood.
When the device is submerged in water and the shaft 7 is rotated, the impeller 4: will cause the vanes 5 to suck the water into the casing 1 and to throw this water by centrifugal force 7 against the vanes 3. The impeller is designed to rotate at a high speed, for example, from 1100 R. P. M. to 3600 R. P. M. or higher. The
travel of the peripheral'edge of the impeller at these speeds will range from 1600 to 2000 feet per minute. This is sufiicient to throw the water by centrifugal force against the vanes 3, and these vanes cooperate with the vanes to lift the water vertically and atthe same time whirl the water.
The water thus lifted enters the passages formed by the portions of the casings 1 and 9, and the force of the water entering these passages will be sufficient to move it throughata depth upto twenty-five feet.
" thirds the diameter of the runner.
out the lengths of the passages, and the'portions 10 willchange the whirling action of the water to a direct vertical movement of the water. If more than one pump is used, the passages 11 formed by the portions 10 will deliver the water to thenext higherimpeller. In this way the water is lifted'from impeller to impeller until it is given the necessary speed and forceto move vertically through the remainder ofthecasing disposed between the pumps and the top of the well.
When the device is used on top of the well,
it is first primed and then it will create sufficient suction to pull the waterfrom the well In practice, the runners or impellers 4 are placed approximately six inches apart when more than one impeller is used, and all are driven from the same shaft 7. If a greater lift and less volume is desired, the blades or vanes 3 and 5 are inclined at a greater angle from the horizontal. The opposite is true when less lift and greater volume is desired.
, I have foundthat the pump will operate more efiicientl when the height of the runner 1 is one-thir to two-thirds its outside diameter. I have further found that the'best results are obtained when thehub 6 of the runner at its top faceis approximately two- Tapering I of the bottom of the hub 6 provides a larger water inlet which also increases the efficiency of the device. The alternate vanes3 (see Figure 4) which are extended as at 10 continue in an inclined plane for approximately one-sixth .60 i which in event a lowering water-table leaves the installation above the water lever of its supply. Other-turbines must have their units submerged at all times in order to operate.
The only wear taking place will be between the impeller blades and the casing blades. A close fit is'not necessary at these points to secure economical operation ,be-
' cause the centrifugal action of the runner or impeller will bridge any reasonable gap.
The device lends itself to single or multiple installations of units to operate effectively over a wide range of duty heads and to combine suction with lift.
The extension of the vanes in the casing or bowl above the runner or impeller, together with the shape of such vanes or blades which changes the rotary motion ofthe pumped li uids to a vertical motion, is very vital to efiicient operation. This has been proved by experiment, and such straightening members, i. e. the portions 10, are often called spiders and are to beinstalled betweeneach runnerbowl unit and also above the highest unit.
Although I'have shown and described one embodiment of my invention, it is to be understood that the same is susceptible of various changes, and I reserve the right to employ such changes as may come within the scope ofthe claims hereto annexed.
I claim;
1.
