Filed:
Jan 21, 1993
Appl. No.:
8/006646
Inventors:

Abstract:
A solar powered pumping system has a ground level walking beam pumping unit and a downhole pump unit which pump liquids during daylight hours. The walking beam pumping unit has a solar powered electric motor which drives a flywheel through drive wheels and a centrifugal clutch to pivot a fulcrum beam having counterweights at one end. The other end of the fulcrum beam is connected by a lift wire to the downhole pump. The downhole pump has a pump housing with a stationary check valve at its upper end connected to a supply conduit extending to the surface. A traveling check valve/piston inside the pump housing is moved on the up stroke by a lift rod slidably mounted on the exterior of the housing which has a top end connected to the lift wire and a lower end connected to the traveling check valve/piston through a longitudinal slot in the lower housing. The traveling check valve/piston is returned on the down stroke by a tension return spring connected between the traveling check valve/piston and the pump housing. On the down stroke the traveling check valve opens and the stationary check valve at the top of the pump housing closes allowing liquid to enter.
