Embodiment Construction

[0035] In the following description, for purposes of explanation, numerous specific details are set forth by way of example in order to provide a better understanding of the present invention. It should be apparent, however, that the invention may be practiced without these specific details.

[0036] In order to increase the overall efficiency and efficiency range of the pumps used according to the invention, positive displacement piston pumps (preferably but not necessarily double acting pumps) are chosen. This type of pump usually consists of a cylinder and a piston / plunger that moves back and forth within the cylinder. The pump is equipped with two check valves that open and close in synchronized cycles to allow the pumping action. Such positive displacement piston pumps typically have an efficiency of 90%-95%.

[0037] In the case of a single-acting reciprocating piston pump, water is pumped in only one of the stroke directions. The use of a single-acting reciprocating ...

Abstract

A system is provided for retrieving efficiently water from a well. The system comprises: a collector operative to collect renewable energy and convert it into electrical energy; a positive displacement pump comprising a servo motor that is energized by the electrical power, adapted to be submersed in a well and retrieve water therefrom; an egress means adapted to convey water retrieved from the well; an electronic controller configured to adapt the electrical energy being retrieved from the renewable source with the power being consumed by the positive displacement pump; and an egress means adapted to convey water retrieved from the well. Optionally, the system further comprises a water storage means for holding water retrieved from that well.

Description

technical field [0001] The present disclosure relates generally to the use of intermittent energy sources to power devices, and in particular to the use of off-grid solar powered devices, such as pumps. Background technique [0002] Water production from remote wells for plant irrigation, livestock, and other applications has long been problematic in terms of low yields of solar pumping systems for deep wells, failure rates of windmill water production, and maintenance costs and inaccessibility. Many in the industry resort to the use of on-site generators, which require repeated trips to remote well locations to provide fuel and start the generators to pump the required water to meet water consumption needs. Solar power has been found to be an effective answer to this challenge, but the flow rates in deep wells using solar water pumping systems are typically very low compared to the flow rates of standard deep well pumps supported by AC power. Solar energy production depend...
