ABSTRACT:
A solar deep well steam pump has a solar collector, a steam boiler in the collector's focus, a deep well bladder pump having an actuating tube and a water delivery tube, and a mechanism periodically injecting steam under pressure from the boiler into the actuating tube of the bladder pump, the mechanism having an expansion chamber connected to the actuating tube of the bladder pump, a long period pendulum swinging by gravity to a first position, a steam injection valve between the boiler and the expansion chamber, the steam injection valve being opened by the pendulum in the first position, an impulse bladder connected to the expansion chamber so that steam pressure in the expansion chamber inflates the impulse bladder against the pendulum in the first position to urge the pendulum against the force of gravity toward a second position, an exhaust valve leading from the expansion chamber to the atmosphere, the exhaust valve being opened by the pendulum in the second position, the injection of steam into the expansion chamber by the injection valve forcing water down the actuating tube of the bladder pump and forcing pumped water from the delivery tube, the release of pressure in the expansion chamber by the exhasut valve allowing water to be forced back up the actuating tube into the expansion chamber for a subsequent pump cycle. A multi-layer pump bladder is adjustable according to well depth. The pump can also be operated by any source of compressed air or gas.
