Abstract
The utility model relates to a wear preventing and pumping aiding efficient centralizing ring for a centralizer. The utility model mainly solves the problem of the small liquid flow passing area of the existent centralizer. The utility model is characterized in that the inside of the lower part of a cylinder-shaped main body is provided with a ring (3) with a square hole (2), the outside of the main body is provided with at least a spiral penetrating groove (4), and the inside of the four angles of the square hole (2) is a spiral flow passing passage (5). The wear preventing and pumping aiding efficient centralizing ring for a centralizer has the characteristics that the utility model not only has a good wear preventing effect, but also has a large liquid flow passing area.
Description
Technical field:
The utility model relates on the sucker rod of oil recovery field, oil field used centralizer, particularly abrasionproof to be helped and takes out synergy centralizer centering ring.
Background technology:
At present along with the deepening continuously of oil field development, pumping production extensively utilizes in the oil field.And when driving the sucker rod repeating motion by oil pumper, the eccentric wear phenomenon of sucker rod and oil pipe is more and more serious.In order to solve eccentric wear, the centralizer that uses on the oil field is of all kinds at present, and these centralizer fixed forms are improved, and the effect of anti-eccentric wear is improved, but their liquid area of passage generally dwindles, and causes the liquid measure of adopting of oil well to descend.
The utility model content:
In order to overcome the existing little deficiency of centralizer liquid area of passage, it is effective that the utility model provides a kind of abrasionproof to help to take out synergy centralizer centering ring, this abrasionproof to help to take out the not only anti-eccentric wear of synergy centralizer centering ring, and have the big characteristics of liquid area of passage.
The technical solution of the utility model is: this abrasionproof helps to be taken out synergy centralizer centering ring and comprises the centralizer main body, is the ring in cubic hole in the cylindrical-shaped main body bottom, and main body has a saturating groove of spiral outward at least, is the spiral flow channels in four jiaos of cubic hole.
The saturating groove of above-mentioned spiral is 4.
The beneficial effect that the utlity model has is: this abrasionproof help take out synergy centralizer centering ring since outside main body, have the saturating groove of spiral and in the spiral flow channels is arranged, thereby increased area of passage, when sucker rod is worked, the oil of oil well pump extraction has the spiral flow channels to flow out in can straightwayly reaching by the saturating groove of spiral, so just improve and adopt liquid measure and pump efficiency, reduced the wastage of oil well pump, improved the stress condition of sucker rod, and anti-eccentric wear is effective.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is vertical views of Fig. 1.
1-main body among the figure, hole, 2-four directions, 3-ring, the saturating groove of 4-spiral, 5-spiral flow channels.
The specific embodiment:
Below in conjunction with accompanying drawing will the utility model is described in further detail:
In conjunction with shown in Figure 2, this abrasionproof helps to be taken out synergy centralizer centering ring and comprises centralizer main body 1, is the ring 3 in cubic hole 2 in cylindrical-shaped main body 1 bottom by Fig. 1, and main body 1 is outer 4 saturating grooves 4 of spiral, is spiral flow channels 5 in four jiaos of cubic hole 2.
During actual the use, this abrasionproof helps to be taken out synergy centralizer centering ring and is enclosed within on the sucker rod, fix by nut again, when the sucker rod cycle operation, the oil of oil well pump extraction flows out by saturating groove 4 of spiral and spiral flow channels 5, so just improves and adopts liquid measure and pump efficiency, has reduced the wastage of oil well pump, improved the stress condition of sucker rod, and anti-eccentric wear is effective.
Claims (2)
1, a kind of abrasionproof helps and takes out synergy centralizer centering ring, comprise centralizer main body (1), it is characterized in that: cylindrical-shaped main body (1) is the ring (3) in cubic hole (2) in the bottom, and main body (1) is outer to have a saturating groove of spiral (4) at least, is spiral flow channels (5) in cubic hole (2) four jiaos.
2, abrasionproof according to claim 1 helps and takes out synergy centralizer centering ring, it is characterized in that: the saturating groove of spiral (4) is 4.
