You can use pause, or run at reduced speed on mute to help read the fast moving screen script. U.S. PATENT #10,202,973 issue date 02-12-19 - a moving weight patent. The moving weight can function to make negative torque, plus with the moving weight in a forward position the inherent weight of the down hole load adds to the negative torque which is to be offset by controlled drag from the generators using a smart system to regulate LIM switching between motoring and generating, the speed of the moving weight, strokes per minute, and variable crank speed while stroking for maximizing efficiency.
This invention moves in real time the position of a sliding counterweight to reduce lifting and lowering forces/torque to be negative torque that is harvest-able energy. On a reciprocating beam pump a sliding beam counterweight is attached to a positioning drive on the beam and is intelligently positioned to achieve lowest torque and negative torque achievable from combining both the counterweight and the load for a negative counterbalance effect. Positioning can be calculated by simply recording ammeter readings which are merged with crank position readings and processed into signals sent to the positioning drive which causes the sliding counterweight to move to the best position on the reciprocating beam to achieve near to lowest amps or when negative is switched to generating mode to harvest negative torque at the prime mover and the other onboard generators. Or a mutually compatible more sophisticated method has a more complex system controller compute torques to insert into a machine learning algorithm that compute and send signals to the positioning drive to intelligently position the sliding counterweight to achieve as low force/torque and negative torque as the machine learning algorithm calculates as beneficial.
U.S. PATENT 10,340,755 B1 issued 07/02/19 - this is an issued onboard generators patent. The prime mover will always be available but these onboard generators are intended to efficiently add capacity. Some of the rotors actuate from gravity, the beam actuated piston type is mechanical. They can switch between motoring and generating for best efficiency. Additionally, when crank rotation is clockwise the effective counterweight of the generator swaying on extended pitman arms above the equalizer can reduce torque required to lift and lower the unbalanced load by increasing counterbalance effect when swayed away from the well load on the upstroke and decreasing counterbalance effect when swayed toward the well load on the downstroke. This swaying weight effect is patented also.
An energy harvester and converter that can supplement electric power to actuate a reciprocating walking beam pumping unit’s prime mover, auxiliary devices, and control devices. In one embodiment, the walking beam pumping unit kinetic energy can assist gravity actuated linear and circular generators attached on the reciprocating walking beam, crank arms, pitman arms, head, and articulated reciprocating counterweight. The electro mechanical devices switch between generating and motoring and send electric current to a capacitor for distribution. In another embodiment, the walking beam pumping unit kinetic energy can assist a mechanically actuated linear generator attached to the reciprocating walking beam and foundation. Used to supply supplemental power for the lifting and lowering of loads with a reciprocating walking beam pumping unit and auxiliary devices.
