Pumping unit With balancing mechanism TORQUE

摘要

Pumping unit, characterized in that the crank shaft is mechanically connected to an additional counterweight shaft, rotating with a frequency twice larger than the rotational speed of the crank and the shaft one or two counterbalancing mechanisms, consisting of at least one rotor, wherein on both ends of the rotor installed counterweights which when the rotor shaft moves along the guides by means of rollers and moved by the rotor by means of rollers than at the shaft the counterweight mechanism is mechanically coupled to the shaft complement tional rotor with counterweight, the rotational frequency is twice the frequency of rotation of the counterweight mechanism, a moment which produces the counterweight mechanism together with an additional rotor with counterweight is not less than the time required for the efficient operation of the pumping unit.
