Abstract
The utility model relates to an eccentric packing for a sucker rod, belonging to the packing of a sealing part used at the sucker rod of a pumping unit. The utility model is characterized in that the eccentric packing for the sucker rod is circular-ring shaped; a packing hole is arranged in the center of the packing; the packing hole is eccentric; the eccentric value of the packing hole and the packing is between 4.5mm and 5.5mm. The utility model has the advantages that eccentric design of the packing hole of the packing meets the operating requirement of factual eccentric displacement of the smooth rod; thus, the smooth rod can be arranged at the sealing center, which avoids the eccentric wear for the packing; the sealing is good. The utility model is suitable for the pumping unit if the packing does not been abraded seriously by the smooth rod.
Description
One, technical field:
The utility model relates to the seal packing that uses on the oil pumping machine oil pumping bar in the field produces, specifically is the eccentric packing of sucker rod.
Two, background technology:
The packing that generally uses in the oil recovery process of oil field is an annular at present, packing hole in the middle of it is concentric with packing, and sucker rod has produced error for various reasons when location and installation, making polished rod produce deflection when pumping tilts, polished rod can be partial to friction to the concentric packing that is installed in the rod packing box like this, cause the seal clearance between polished rod and the packing excessive, sealing effectiveness is poor, make production tree often run oil, also make simultaneously the shortening in application life of this concentric packing, waste is serious.
Three, summary of the invention:
The purpose of this utility model provides the eccentric packing of a kind of sucker rod, and the eccentric packing of this sucker rod has solved the eccentric wear problem that exists between the concentric packing of former usefulness and the polished rod, allows polished rod that the deflection displacement is arranged.
The technical scheme that its technical problem that solves the utility model adopts is: the eccentric packing of this sucker rod is an annular, in the middle of the packing packing hole is arranged, and the packing hole is eccentric, and the eccentricity value of packing hole and packing is between 4.5 millimeters-5.5 millimeters.
Beneficial effect:
The utility model is according to the reason of polished rod eccentric wear, the packing hole of this packing is designed to eccentric, satisfied the service requirement of the in esse deflection displacement of polished rod, because all there is identical deflection displacement in packing with polished rod, polished rod can be in the position of center seal, can not cause eccentric wear to packing; The eccentricity value of the utility model packing hole and packing suits to use in to the not serious oil pumper of packing eccentric wear at polished rod between 4.5 millimeters-5.5 millimeters.
Four, description of drawings:
Fig. 1 is a sectional view of the present utility model;
Fig. 2 is a vertical view of the present utility model;
Fig. 3 is the sectional view of another kind of embodiment.
1 packing, 2 packing holes
Five, the specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
In conjunction with illustrated in figures 1 and 2, the eccentric packing of this sucker rod is an annular, in the middle of the packing 1 packing hole 2 is arranged, and packing hole 2 is eccentric, and packing hole 2 is 4.5 millimeters with the eccentricity value of packing 1.
Fig. 3 is the sectional view of another kind of embodiment, and present embodiment mid-game root hole 2 is 5.5 millimeters with the eccentricity value of packing 1, and other structure is with shown in Figure 1 identical.
When the utility model uses, be contained in the packing box of oil pumping machine oil pumping bar, because the packing hole 2 of this packing is designed to eccentric, satisfied the service requirement of the in esse deflection displacement of polished rod, overcome concentric packing the deflection displacement can not be provided, and polished rod is in order to obtain to be partial to the problem of displacement to concentric packing eccentric wear, good sealing effect.The eccentricity value of the utility model packing hole 2 and packing 1 is fit to polished rod to using in the not serious oil pumper of packing eccentric wear between 4.5 millimeters-5.5 millimeters.
Claims (1)
