Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
As depicted in figs. 1 and 2, the utility model discloses a kind of anticorrosive abrasion-proof sucker rod 1, it comprises the body of rod 2, by offering external screw thread respectively in the two ends of the body of rod 2 two nipples 3 of being formed and two arrange at contiguous two nipple 3 places of the body of rod 2 respectively for the tool-joint 4 with pipe wrench mating reaction.Wherein, the external surface of the body of rod 2 is provided with corrosion-resistant coating 5.For better fixing this corrosion-resistant coating 5, being also provided with adhesive linkage 6 in the external surface of the body of rod 2 in the present embodiment, being fixed on firmly on the body of rod 2 for by corrosion-resistant coating 5.This adhesive linkage 6 by cementing agent (specifically can adopt special chemical adhesive) is evenly coated in the body of rod 2 outer wall on formed.Just corrosion-resistant coating 5 to be fixed on the body of rod 2 when cementing agent is in moisture state during concrete operations, to be bonded dose solidifies rear high temperature vulcanized, just corrosion-resistant coating 5 and the body of rod 2 close adhesion can be made, no matter which kind of vibrations corrosion-resistant coating 5 anticorrosive abrasion-proof sucker rod 1 fixed by said method is subject to or collides with in the process of transporting and use, it all can not come off easily from the body of rod 2.
Further, continue composition graphs 2, this corrosion-resistant coating 5 is preferably rubber layer.Why corrosion-resistant coating 5 being set to rubber layer is because rubber belongs to inert material, not easily with other material generation chemical reaction, thus there is excellent corrosion resistance, the corrosion as bittern, acid, alkali, salt, wet goods chemical substance can be resisted, be out of shape large due to caoutchouc elasticity simultaneously and there is superpower adhesive power, can combine with the metal outer wall closed seamless gap of the body of rod 2, liquid cannot be contacted with the metal outer wall of the body of rod 2, to improve the corrosion resistance of the body of rod 2 further.And rubber not only friction factor lower than the friction factor of metal, the friction of coarse fluid can be resisted, but also possess good suppression wax deposition and the characteristic of fouling, and without the need to carrying out wax removal process to the inwall of oil pipe.
Preferably, the thickness of the rubber layer in the present embodiment is 2mm-4mm, the rubber layer of this thickness thoroughly can cover the sags and crests on the outer wall of the body of rod 2, and put in after in oil pipe at anticorrosive abrasion-proof sucker rod 1 its body of rod 2 is separated with tube inner wall, prevent from the body of rod 2 of anticorrosive abrasion-proof sucker rod 1 from producing with the inwall of oil pipe to rub, significantly alleviate the body of rod 2 of anticorrosive abrasion-proof sucker rod 1 and the wearing and tearing of oil pipe, the application life of anticorrosive abrasion-proof sucker rod 1 is extended.
As in Figure 3-5; the utility model discloses a kind of beam hanger box cupling 7 simultaneously; for connecting two anticorrosive abrasion-proof sucker rods 1 (beam hanger box cupling 7 has for screw thread in being threaded with the nipple 3 of anticorrosive abrasion-proof sucker rod 1); this beam hanger box cupling 7 comprises the box cupling body 8 of circular tube shaped; the two ends of this box cupling body 8 have the internal thread that the nipple 3 for the two ends with anticorrosive abrasion-proof sucker rod 1 is threaded respectively, and box cupling body 8 is outer is also provided with anti-corrosion protection cover 9.This anti-corrosion protection overlaps outside all outstanding box cupling body 8 in 9 cylindrical and its two ends; the threaded connector 3 of anticorrosive abrasion-proof sucker rod 1 end so not only can be made to be covered by anti-corrosion protection cover 9 completely; good protection box cupling body 8, effectively can prevent the effect of the interior screw thread of dielectric corrosion box cupling body 8 simultaneously.
Further, the anti-corrosion protection cover 9 in the present embodiment is fixed on box cupling body 8 by adhesive linkage equally.This adhesive linkage and the above-mentioned adhesive linkage 6 be arranged on the body of rod 2 of anticorrosive abrasion-proof sucker rod 1 prepare material and using method is identical, be same substance.Anti-corrosion protection cover 9 is made up of quality of rubber materials, and thickness is preferably 2mm-4mm equally, and the rubber namely adopting thickness to be preferably 2mm-4mm makes.Arranging this anti-corrosion protection cover 9 is because box cupling body 8 is being connected consequence by huge thrust with anticorrosive abrasion-proof sucker rod 1; and be less than the spacing between the body of rod 2 of anticorrosive abrasion-proof sucker rod 1 and tube inner wall due to the spacing between box cupling body 8 and tube inner wall; what the anticorrosive abrasion-proof sucker rod 1 be therefore connected by beam hanger box cupling 7 when many moved to carry out to be worn at first when pumping operation in oil pipe is beam hanger box cupling 7; and dielectric corrosion box cupling body 8 just effectively can be prevented after this anti-corrosion protection cover 9 is set, greatly extend its application life.Continue composition graphs 3, Fig. 4 and Fig. 5; box cupling body 8 in the present embodiment is provided with a draw-in groove 10 for being connected with fixing instrument (as pipe wrench); anti-corrosion protection overlaps 9 corresponding draw-in groove 10 places and is provided with the breach 11 with the notch form fit of draw-in groove 10, to make draw-in groove 10 outside exposed.
As shown in Figure 6, the present invention also discloses a kind of beam hanger group, comprises multiple above-mentioned anticorrosive abrasion-proof sucker rod 1 and beam hanger box cupling 7.During concrete operations, many anticorrosive abrasion-proof sucker rods 1 yi word pattern is arranged, connected by a beam hanger box cupling 7 between two often adjacent anticorrosive abrasion-proof sucker rods 1, many anticorrosive abrasion-proof sucker rods 1 just form a stock and beam hanger group after being connected like this, then just can stretch in oil pipe and carry out oil producing operation.
Above embodiment is only exemplary embodiment of the present utility model, is not used in restriction the utility model, and protection domain of the present utility model is defined by the claims.Those skilled in the art can in essence of the present utility model and protection domain, and make various amendment or equivalent replacement to the utility model, this amendment or equivalent replacement also should be considered as dropping in protection domain of the present utility model.
