Pitless well adaptor with high-efficiency flow divider
View Patent ↗In various exemplary embodiments, the present disclosure relates to a flow divider in a spool for a pitless adaptor included in a booster station and/or well construction. The flow divider has a generally triangular shaped cross-section that efficiently helps direct water flow from a vertical to a horizontal direction reducing pressure head lost in the spool and thereby increasing the energy efficiency of the system. In various exemplary embodiments, the flow divider may have a variety of cross-sectionals shapes and sizes depending on the size and requirements of the well or booster station.
1. A pitless adapter, comprising:
a discharge body defining a chamber having at least one outlet;
a spool having a body defining a chamber, comprising:
at least one inlet to the spool chamber;
at least one outlet from the spool chamber; and
a flow divider with a generally triangular prism shape and having at least one face in the spool chamber; and
wherein the spool chamber outlet is in fluid communication with the discharge body chamber; and
a submersible pump coupled to the spool and in fluid communication with the spool chamber inlet.
2. The pitless adapter of claim 1 , wherein the at least one flow divider face is generally flat.
3. The pitless adapter of claim 1 , wherein:
a face of the flow divider forms an inclined angle with an imaginary horizontal line; and
the inclined angle is from about 15 degrees to about 70 degrees.
4. The pitless adapter of claim 3 , wherein the inclined angle is from about 35 degrees to about 50 degrees.
5. The pitless adapter of claim 4 , wherein the inclined angle is from about 40 degrees to about 45 degrees.
6. The pitless adapter of claim 1 , wherein the flow divider has two faces and a tip between the faces.
7. The pitless adapter of claim 6 , wherein at least two spool chamber outlets are located on a side of the spool body proximate to the top of the spool; and
wherein the tip of the flow divider is approximately equidistant from the spool chamber outlets.
8. The pitless adapter of claim 1 , wherein:
the spool body further comprises:
a spool chamber top portion with at least a part of such top portion being at least partly defined by the generally triangular prism shape of the flow divider;
a one of the at least one inlet to the pool chamber is located at a lower end of the spool;
at least two chamber outlets are located on a side of the spool proximate to the top of the spool;
wherein the flow divider has two faces, each face addressing a spool chamber outlet;
the spool is coupled to the discharge body such that at least a portion of the spool is within the discharge body including the two chamber outlets; and
the submersible pump is suspended below the spool.
9. A well construction, comprising:
a vertical well casing;
a discharge body defining a chamber having at least one outlet coupled to and located within the well casing;
a spool being insertable into the well casing, comprising:
a body defining a chamber;
one chamber inlet located at a lower end of the spool;
two generally oppositely disposed chamber outlets located on a side of the spool proximate to the top of the spool; and
a flow divider having at least one face within the chamber and having a generally triangular prism shape;
wherein the flow divider has two faces, each face addressing a spool chamber outlet;
the spool is coupled to the discharge body such that at least a portion of the spool is within the discharge body including the two chamber outlets; and
a submersible pump suspended below the spool with an outlet in fluid communication with the spool inlet.
10. The well construction of claim 9 , wherein the wherein the at least one flow divider face is generally flat.
11. The well construction of claim 9 , wherein:
a face of the flow dividing forms an inclined angle with an imaginary horizontal line; and
the inclined angle is from about 15 degrees to about 70 degrees.
12. The well construction of claim 11 , wherein the inclined angle is from about 35 degrees to about 50 degrees.
13. The well construction of claim 12 , wherein the inclined angle is from about 40 degrees to about 45 degrees.
14. The well construction of claim 9 , wherein the flow divider has two faces.
15. The well construction of claim 9 , wherein the tip of the flow divider is approximately equidistant from the outlets.
