Abstract
The invention provides a guide-wheel type long-stroke energy-saving oil extractor, which comprises a motor, an automatic brake, a gear reducer, a gear reducer input and output shaft coupling and a drive wheel arranged on a top platform. One end of a traction rope is connected with a smooth rod; the other end is connected with a fixing shaft inside the drive wheel through a guide wheel; one end of a balancer traction rope is attached to the fixing shaft inside the drive wheel; the other end is connected with a balancer case through a balancer rope hanger. When the drive wheel is running along forward and reverse directions, the motor drives the drive wheel, the steel rope and the guide wheel through the gear reducer input and output shaft coupling, so that the oil extractor rod and the deep well pump can fulfill straight line reciprocal movement. The oil extractor has the advantages of reasonable structure, easy adjustment, convenient maintenance, reliable operation, high extracting efficiency, environmental protection and saving energy, etc. Compared with the beam-pumping units, the oil extractor can save power by 30 to 50 percent and improve pumping efficiency by over 20 percent. While performing well maintenance work, rotating the guide wheel bracket inclined backward by 50 degrees to 60 degrees, thereby avoiding well openings conveniently. The guide-wheel type long-stroke energy-saving oil extractor can be utilized in all types of oil fields.

Guide-roller type long stroke energy-saving pumping unit provided by the invention is characterized in that comprising base (1), small footprint (2) frame (3), polished rod (4), preceding support (5), polished rod eye (6), pull rope (7), directive wheel support (8), directive wheel axle bed (9), directive wheel (10), reducer (11), driving wheel (12), upper mounting plate (13), ladder (14), (15) are supported in the back, counterweight slide rail (16), counterweight pull rope (17), counterweight polished rod eye (18), main ballast box (19), pulley (20), secondary ballast box (21), cushion pad (22), switch board (23), guardrail (24), two-layer platform (25), motor (26), live axle bearing (27), output shaft shaft coupling (28), input shaft coupling (29) decelostat (30) turnover bracket (31); Described reducer (11) links to each other with motor (26) by power shaft shaft coupling (29), decelostat (30), and reducer (11) output shaft links to each other with driving wheel (12) by shaft coupling (28); Described balance weight body is made up of main ballast box (19), secondary ballast box (21), pulley (20), and heavy metal powder is equipped with in wherein main ballast box and secondary ballast box inside; Described pull rope (7) one ends are connected with polished rod (4), and an end is connected by the inner fixed axis of directive wheel (10) and driving wheel (12), and described counterweight pull rope (17) one ends are connected with the fixed axis of driving wheel inside, and the other end is connected with counterweight polished rod eye (18).
In guide-roller type long stroke energy-saving pumping unit provided by the invention, be provided with hard flank of tooth reducer, moment of torsion is big, reliability is high, efficient is high, make oil pumper have shock resistance, overload-resistant ability improves greatly, reducer input, output shaft at the same side motor at the main frame center, topology layout is reasonable, operates steadily, thus the application life of having improved complete machine.Described motor is a switched reluctance machines, has the advantages that starting current is little, moment of torsion big, be fit to frequent rotating operating mode.Described balance weight body is made up of main ballast box and secondary ballast box, and heavy metal powder is equipped with in inside, can accurately adjust counterweight.
Controller can control that motor softly stops, soft opening, and reduces that commutation suddenly starts and the shock loading that causes, thus the life-span of having improved transmission system greatly.
Guiding wheel carrier (7) can hypsokinesis 50 °～60 °, can get out of the way well head easily during workover treatment.
This oil pumper has upper mounting plate balance of plant layout in sum, rational in infrastructure, advantages such as adjustment is easy, easy to maintenance, reliable, pumping efficiency is high, the operation noise is low, environmental protection and energy saving.Compare with conventional beam-pumping unit and can economize on electricity 30～50%, pump efficiency improves more than 20%.This guide-roller type long stroke energy-saving pumping unit can be widely used in all kinds oil field.
