Pumping unit With balancing mechanism TORQUE

摘要

Pumping unit, characterized in that the shaft of the crank is mechanically coupled to the shaft, at least one counterweight mechanism consisting of two rotors, which is mounted connector assembly which when the rotor shaft moves along the guides by means of rollers and on the rotor by means of rollers, as well as via bearings via rollers on one arm moves on which the cargo is secured, and a lever shaft is set parallel to the rotor shaft, the moment which produces the counterweight mecha m, not less than the time required for the performance of the pumping unit.
