Abstract
The utility model provides a long-stroke energy-saving pumping unit, which is simple in structure, low in energy consumption, fine in balancing, low in reversing impact and convenient in maintenance. Currently, beam pumping units are most widely applied domestically and internationally, have the shortcomings of long transmission chains and low mechanical efficiency due to the characteristics of four-link structures, and large pulsation, low load rate and low system efficiency due to counterweight structures, and are larger in steel consumption, energy consumption and the like of equipment. The long-stroke energy-saving pumping unit is characterized by comprising a base, a frame, a counterweight, a rotary horse head frame, a rotary horse head, a motor, a driving wheel and a speed reducer. The rotary horse head frame consists of I-shaped steel and is telescopic, so that a suspension point is precisely aligned with a well head to avoid eccentric wearing of a well rod and cycle for well maintenance is prolonged, and the rotary horse head frame can also be inclined so as to open the well head to facilitate well maintenance. The counterweight consists of different weights and can be precisely adjusted for balancing. The long-stroke energy-saving pumping unit has the advantages of fine balancing effect, simple structure, cost reduction, stability in running and energy source economization.
