Abstract
The utility model discloses a pumping rod shock absorber which comprises an upper connector and a lower connector, wherein a center rod is fixed in the upper connector; a cylinder barrel which is in sealing connection with the center rod and accommodates hydraulic oil is arranged outside the centre rod; one end of the cylinder barrel is fixedly connected with the lower connector; a damping piston hinged with the center rod is arranged in the cylinder barrel; and a damping spring is arranged on the center rod between the cylinder barrel and the upper connector in a sleeving manner. The pumping rod shock absorber is simple in structure, reasonable in design and good in buffer performance, and can reduce axial and radial stress and prolong the service life of the pumping rod.
Description
Technical field
The utility model relates to the oil drilling machine technical field, relates in particular to a kind of sucker rod damper.
Background technology
At present, pump at deep-well or complicated well and produce in each oil field, the sucker rod roofbolt of down-hole is owing to be subjected to the influence of factors such as OIH liquid buoyancy, frictional force and fluid thickness power, the bottom sucker rod is stressed very complicated, sucker rod is easy to occur problems such as bottom rod broken, dropout and eccentric wear like this bearing bigger axial force and radial load in the running up and down.Existing sucker rod is low application life, often needs shutdown and repaire well, has influenced operating efficiency, and has increased working strength of workers.Though OIH liquid can be directly as buffer, thereby plays the bumper and absorbing shock effect, because the rigid particle of oil-containing impurity mostly in the fluid, these particles enter fluid cylinder and can cause the fluid cylinder inwall to scratch, thereby cause defective shock absorber, and damping effect is bad.
The utility model content
The utility model provides a kind of simple in structure, reasonable in design at the defective that prior art exists, and shock-absorbing capacity is good, can subdue axially and radial stresses, can prolong sucker rod a kind of sucker rod damper in application life.
For solving the problems of the technologies described above, the technical solution of the utility model is: the sucker rod damper, comprise top connection and lower contact, be fixed with center-pole in the described top connection, the outside of described center-pole is provided with the cylinder barrel that is tightly connected with it and fills hydraulic oil, one end of described cylinder barrel is fixedlyed connected with lower contact, is provided with the daming piston hinged with described center-pole in the described cylinder barrel, is arranged with damping spring on the center-pole between described cylinder barrel and the top connection.
The openend of described cylinder barrel is provided with the O-ring seal for sealing.
After having adopted technique scheme, the beneficial effect that the utility model is obtained is: the utility model is simple in structure, and is reasonable in design, and shock-absorbing capacity is good, can subdue axially and radial stresses, prolonged the application life of sucker rod.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
As shown in Figure 1, the sucker rod damper, comprise top connection 1 and lower contact 2, be fixed with center-pole 3 in the described top connection 1, the outside of described center-pole 3 is provided with the cylinder barrel 4 that is tightly connected with it and fills hydraulic oil, one end of described cylinder barrel 4 is fixedlyed connected with lower contact 2, is provided with the daming piston 5 hinged with described center-pole 3 in the described cylinder barrel 4, is arranged with damping spring 6 on the center-pole between described cylinder barrel 4 and the top connection 1.
The openend of described cylinder barrel 4 is provided with the O-ring seal 7 for sealing.Arrange by sealing, can effectively prevent the hydraulic oil leakage.
During use, by splendid attire hydraulic oil in cylinder barrel 4, and the daming piston 5 hinged with center-pole 3 is set in cylinder barrel 4, can alleviate sucker rod directly collides, play the bumper and absorbing shock effect, thereby prevent that sucker rod is subjected to axial fluctuating load, has prolonged the application life of sucker rod; Circumferentially disperse to daming piston 5 by the hinged pressure that center-pole 3 is born, reduce the bad moment of torsion of sucker rod, alleviate radial stresses, prolonged the application life of sucker rod; And be arranged with damping spring 6 by the center-pole 3 between cylinder barrel 4 and top connection 1, can play the bumper and absorbing shock effect together with daming piston 5, slow down the sucker rod downstream rate, thereby subdue axial stress, avoid sucker rod to bend, and further improved damping effect, thereby reduced fracture and the dropout phenomenon of sucker rod, prolonged the application life of sucker rod.
The utility model is simple in structure, and is reasonable in design, and shock-absorbing capacity is good, can subdue axially and radial stresses, prolonged the application life of sucker rod.
Claims (2)
