Submersible magnetic pump for solar-powered pumping systems for pumping water from wells

摘要

The two iron cores (7) forming the reciprocating drive for the solenoid pump are joined by a non-magnetic steel tube and have a return spring support. The inlet valve has a ring-shaped flap element (2) held down by a relatively weak spring (3). A spring loaded outlet valve (8) vents water out of the pump chamber into an outlet chamber (9) with a gas pocket. The gas pocket absorbs the pressure pulses from the pump action and provides a more even outflow of water. The solar generated power has variable pulse length and amplitude, depending on the sunlight level. USE/ADVANTAGE - For pumping water from well. Efficient pump action, small spring forces reduce efficiency by minimal amounts.
