Abstract
The invention relates to a convex counterweight centralizer for a pumping unit, which is composed of a counterweight, a track, a centralizing body, a centralizing seat, a buffer pad and the like, wherein a centralizer is respectively arranged between the four sides of the counterweight and the track; the centralizing body is a semicircular slip which is formed by splitting a seamless steel tube from the center; the opening of the semicircular slip tallies with the track; and a clearance of 20+/-5 mm is ensured. The back of the slip is electrically welded with the centralizing seat, the buffer pad is arranged between the centralizing seat and the counterweight, and the centralizer is tightened to the counterweight by using four high-strength connection screws. The other three centralizers are installed at the left, right and lower positions of the counterweight by using the same method. By using the scheme, the centralizing of the counterweight and track of a pumping unit can be solved, thereby avoiding contact, preventing friction, having no noise and ensuring safe and smooth operation of the counterweight.
Description
Technical field
The present invention relates to the oil field petroleum machinery, particularly the oil field is without beam pumping unit.
Background technology
Beam pumping unit used more than 100 year in the oil field, fast development along with the modernization science and technology, utilize beam pumping unit suction crude oil to seem that gradually some is fallen behind, various energy-conservation with it without beam pumping unit, reduce discharging, the characteristics such as efficient, long stroke, low jig frequency, just adopted by increasing oil field, for example, W type towing oil-pumping machine just belongs to this example.But the counterweight erection device of W type towing oil-pumping machine is not yet perfect, has friction phenomenon to occur when counterweight and guide rail, and making originally to have the abnormal sound that but has that noise sends to send, and track also has the phenomenon of eccentric wear.
Summary of the invention
In order to overcome the defective of above-mentioned W type towing oil-pumping machine, the invention provides a kind of convex counterweight centralizer, both improved runnability, increase the service life again.
Technical scheme of the present invention is such: convex counterweight centralizer for pumping unit is to be made of counterweight, track, centralizer body, righting seat, cushion pad, with the track among, a centralizer body is installed up and down in counterweight, centralizer body is the semicircle slips that seamless steel pipe is cut open from the center, the opening of semicircle slips and track coincide, guarantee the gap of 20 ± 5mm, watt back of the body of slips and righting seat electric welding, and padding cushion pad between righting seat and counterweight, then with 4 high-strength attachment screws, centralizer body is tightened on counterweight.
The invention has the beneficial effects as follows: the righting of adopting technique scheme can effectively solve counterweight of oil pumping unit and track, avoid contact, exempt friction, there is no noise, guarantee counterweight up and down safety and steady operation.
