Well pumping system construction

Claim 2

Well pumping system construction including a well shaft extending downwardly into the ground to a water pool below; a well casing extending from a point above the ground downwardly into said shaft; an inflatable bottom sealing means and a top sealing means spaced within said well casing, said sealing means forming an air and water chamber therebetween with said casing; a water delivery pipe extending from a point above the ground downwardly into the well shaft to said water pool; said delivery pipe being formed with openings, said openings communicating with said chamber; pump means communicating with said delivery pipe for pumping water from the water pool into the chamber; airliquid separator means placed within said chamber; pump control means communicating with said pump means; a water supply pipe connected to said delivery pipe at a point aboveground; air breather means extending from below said bottom sealing means to a point above said top sealing means; and means for inflating said bottom seal.

Claim 3

The construction defined in claim 1 in which the inflatable bottom sealing means includes a pair of spaced plates; in which each plate is formed with an opening, through which openings said delivery pipe extends; in which an inflatable member is located between said plates; and in which said inflating means communicates with said inflatable member.

Claim 4

The construction defined in claim 2 in which the inflatable means is bag-like and is bonded to said pair of spaced plates; in which a pair of oppositely located bosses extend outward from said plates; and in which said inflating means extends through said bosses and communicates with said inflatable means.

Claim 5

The construction defined in claim 2 in which the pair of spaced plates are each formed with central openings and opposite offset openings; in which said delivery pipe extends through said central openings and in which said inflating means extends through said offset openings; in which said plates have peripheral flanges extending inward toward each other; in which said inflatable means is a tire-like boot having a generally flat center portion when expended against said casing; and in which said center section terminates in inturned lips, said lips engaging said plate flanges.

Claim 6

The construction defined in claim 1 in which the inflating means is a molded flexible conduit formed with an inflate passage; in which an opening is provided in said conduit communicating with said inflate passage; and in which said opening communicates with the bottom sealing means.

Claim 7

The construction defined in claim 5 in which electric wires are embedded within said conduit; and in which said wires extend between and connect to said pump means and to said pump control means.

Claim 8

The construction defined in claim 5 in which said conduit means is formed with a breather passage; and in which said breather passage extends from below said bottom sealing means to a point above said top sealing means.

Claim 9

The construction defined in claim 1 in which a housing covers said well casing which extends aboveground; covers said pump control means; and covers said supply pipe.

Claim 10

Well pumping system construction including a well shaft extending downwardly into the ground to a water pool below; a well casing extending from a point above the ground downward into said shaft; a bottom sealiNg means and a top sealing means spaced within said well casing, said sealing means forming an air and water chamber therebetween with said casing; a water delivery pipe extending from a point above the ground downwardly into the well shaft to said water pool; said delivery pipe being formed with openings, said openings communicating with said chamber; pump means communicating with said delivery pipe for pumping water from the water pool to the chamber; air-liquid separator means placed within said chamber; pump control means communicating with said pump means; a water supply pipe connected to said delivery pipe at said terminal point aboveground; and air breather means extending from below said bottom sealing means to a point above said top sealing means.

Claim 11

Well pumping system construction including a well shaft extending downwardly into the ground to a water pool below; a well casing extending from a point above the ground downward into said shaft; a bottom sealiNg means and a top sealing means spaced within said well casing, said sealing means forming an air and water chamber therebetween with said casing; a water delivery pipe extending from a point above the ground downwardly into the well shaft to said water pool; said delivery pipe being formed with openings, said openings communicating with said chamber; pump means communicating with said delivery pipe for pumping water from the water pool to the chamber; air-liquid separator means placed within said chamber; pump control means communicating with said pump means; a water supply pipe connected to said delivery pipe at said terminal point aboveground; and air breather means extending from below said bottom sealing means to a point above said top sealing means.

Claim 12

The construction defined in claim 9 in which said bottom sealing means includes a plate, a flexible cylinder supported on said plate; in which said cylinder has an end wall abutting said plate, and bellows-like side walls forming an open upper end, in which said side walls contact said casing; in which a pair of openings are formed in said cylinder end wall; in which a pair of similar openings are formed in said plate, which plate openings align with said end wall openings; and in which the delivery pipe extends through one pair of aligned openings, and in which the air breather means and pump control means extend through the other pair of aligned openings.

Claim 13

Well pumping system construction including a well shaft extending downwardly into the ground to a water pool below; a well casing extending from a point above the ground downward in said shaft; a top sealing means disposed in said well casing and an inflatable bottom sealing means disposed in said well shaft spaced below said top sealing means, said sealing means forming an air and water chamber therebetween with said casing and shaft; a water delivery pipe extending from a point above the ground downwardly in the well shaft to said water pool; said delivery pipe being formed with openings, said openings communicating with said chamber; pump means communicating with said delivery pipe for pumping water from the water pool to the chamber; air-liquid separator means placed within said chamber; pump control means communicating with said pump means; a water supply pipe connected to said delivery pipe at said terminal point aboveground; and air breather means extending from below said bottom sealing means to a point above said top sealing means.

Claim 14

Well pumping system construction including a well shaft extending downwardly into the ground to a water pool below; a well casing extending from a point above the ground downward in said shaft; a top sealing means disposed in said well casing and an inflatable bottom sealing means disposed in said well shaft spaced below said top sealing means, said sealing means forming an air and water chamber therebetween with said casing and shaft; a water delivery pipe extending from a point above the ground downwardly in the well shaft to said water pool; said delivery pipe being formed with openings, said openings communicating with said chamber; pump means communicating with said delivery pipe for pumping water from the water pool to the chamber; air-liquid separator means placed within said chamber; pump control means communicating with said pump means; a water supply pipe connected to said delivery pipe at said terminal point aboveground; and air breather means extending from below said bottom sealing means to a point above said top sealing means.
