1 Claim.
This invention relates to reciprocating suction pumps such as are used in wells. These pumps ordinarily employ plungers or pistons having cup leathers, which must be frequently pulled for replacement when worn, to prevent undue loss of the necessary' suctional force.
The particular object of my invention is to construct a pump of the above general character in which the usual piston and rod are eliminated, and the pipe column within the well casing serves as the piston.
The above and other objects are carried out by means of the structure shown in the accompanying drawing in which Figure 1 is a side elevation foreshortened, of my improved pump structure;
Figure 2 is an enlarged sectional elevation of the same;
Figure 3 is a fragmentary section of the pump column showing an auxiliary supporting or balancing spring arrangement.
Referring to the numerals of reference on the drawing, and particularly at present to Figures l and 2, I denotes the well casing, supported by and depending from a base 2. This casing has a valve chamber 3 on its lower end, in which is mounted an upwardly opening gravity seated intake valve ll.
Freely slidable in the casing above the chamber 3 is the pump column, made of a number of connected lengths of pipe 5 as usual, the upper one projecting a short distance above the casing and base. An elbow 6 is iitted on the upper end of the column, from which a discharge nipple 'l projects.
A compression spring 8 is disposed about the column between the elbow and the base 2, and is of suiicient strength to support the weight of the column.
Fitted in the lower end of the column is a valve cage andseat 9, cooperating with an upwardly opening gravity seated Valve I0, which closes the lower end of the column.
The elbow 6 at a point axially of the pump column, is flexibly connected to the strap II of an eccentric I2. This eccentric is mounted on a shaft I3 journaled on a rigid framework I4 upstanding from the the base 2. The shaft is provided with a pulley I5 and a balancing flywheel I6, the pulley being belt-connected to a prime mover such as an electric motor l1 mounted on the base 2.
In operation it will be seen that as the motor is driven the pump column will be reciprocated by reason of its connection with the eccentric.
(Cl. 10S-76) As the column descends, any water trapped in the casing chamber 3 will force the valve I0 open and enter the pump column. As the column lifts, the valve I0 oi course closes, while the valve 4 will open due to the suctional eect set 5 up with the upward movement of the pump column, and water will enter the chamber 3.
Repeated reciprocations of the pump column of course cause the water to accumulate and raise in the column, until it reaches and *Hows l0 from the discharge nipple at the top.
The speed at which the pump column is reciprocated depends upon the depth of the well and the internal diameter of the column and the volume of water which may be expected at the discharge orice of the pump is dependent on the length of stroke of the pump column.
The rst two of these factors determine the weight of the body of water being lifted, and since there exists a critical speed, at which the pump column and the body of water contained therein would be oscillating in synchronism, reciprocation of the column at a frequency in excess of this critical speed is required in order to eiect removal of water from the well.
It has been found that, in a well having a depth of approximately 100 feet, a column of about 2 inches diameter reciprocated at a speed of about 300 to 350 cycles per minute will effect removal of a satisfactory amount of water. With a stroke of suflicient magnitude, it appears that, within these speed limits, the water contained within the column is given a denite momentum upwardly which persists even during a portion of the downward or' return stroke of the column. 35 There actually exists therefore an oscillatory phasedifference between the column. and the body of water and it is this difference which produces the ilow of water at the discharge oriiice.
In the event that the weight or length of the pump Icolumn is such that a single spring at the top is insufficient to properly support the depending weight, I may mount an additional supporting spring I8, as shown in Figure 3, at any desired point in the length of the column.
In this arrangement, the top of the spring engages a cup I9 secured on the adjacent length of pipe 5A. 50
The lower ends of the spring rests on the lower end of an enlarged coupling member 20 which connects adjacent section of the well casing IA and forms a housing about the spring so that the latter may have unrestricted freedom of action without rubbing against the wall of the casing.
Having described my claim is:
In a well pump comprising a sectional tubular pump casing adapted to be placed in a well bore and terminating at its lower end below the level of the Water in said well, an upwardly opening valve in, and closing the lower end of, said casing, a tubular pump column disposed within said pump casing, said pump column having an upwardly opening valve in the lower end thereof and a discharge outlet at the upper end thereof, means for reciprocating said pump column with` in said pump casing, and meansfor resiliently invention, what I supporting said column in said casing, said means comprising a. coupling section secured to an end of one of said casing sections, a Sleeve connected to said coupling section and to the adjacent end of another of said casing sections, a tubular member secured to said coupling section and disposed about said pump column, a cup-shaped member secured to said pump column in axially spaced' relation to said tubular member, and a coil spring disposed between said coupling section and said pump column, said spring being positioned partly within said cup-shaped member and partly exterior of said tubular member.
