Description
Technical field
The utility model belongs to the oil field equipment field, relates to a kind of pumpingh well polished rod sealing device.
Background technology
At present, the polished rod seal product of oil pumping machine well head is varied, and the encapsulant of use is also varied, the effect difference, and cost is also different, each have their own advantage.Especially moisture for height, fuel-displaced this class well intermittently, management difficulty is just larger, causes greatly reduce its application life, needs the frequent sealed packing of changing, and affects oil recovery efficiency.
The utility model content
The purpose of this utility model is to provide a kind of cheap, wear-resisting, easy-to-install pumpingh well polished rod sealing device.
The technical solution adopted in the utility model is as follows:
A kind of pumpingh well polished rod sealing device, comprise oil pumping polish rod 10, oil pumping polish rod is through the filling container 6 of sealed packing box 4, and sealed packing 9 is fixed in the filling container 6 of described sealed packing box and wraps up oil pumping polish rod, it is characterized in that, described sealed packing 9 is the bar shaped belt; The circular cone bench-type that the filling container of described sealed packing box 4 is downward convergent; The middle part processing outer lug boss 801 of sealed packing delivery wheel 8, fix a weld-ring 802 in the upper end of sealed packing delivery wheel 8, described outer lug boss matches with weld-ring and blocks the inner convex platform of pressure cap 7 upper ends and leave end play; The top of the bottom embedding sealing packing box filling container of described sealed packing delivery wheel 8 also compresses described sealed packing, the external screw thread interlock on the internal thread of described pressure cap and sealed packing box top; Vertically be provided with the sealed packing delivery chute 803 of inclination on the sidewall of described sealed packing delivery wheel 8;
Described pumpingh well polished rod sealing device bottom is provided with well head and connects base 1, and the oil inner whorl of base that is connected with well head in the ninth of the ten Heavenly Stems 3 connects, and is fixed on the tuningout base 401 of described sealed packing box 4 lower ends.
The bottom of the filling container 6 of described sealed packing box is provided with righting copper sheathing 1.
Described sealed packing 9 is trapezoidal conveyer belt for shape of cross section; The shape of cross section of described sealed packing delivery chute 803 is identical with the shape of cross section of described sealed packing 9.
The angle of inclination of described sealed packing delivery chute 803 is 5-30 °.
Fixed installation handle 701 on described pressure cap 7.
Connect the interior installation righting of base 1 copper sheathing 22 at described well head.
Pumpingh well polished rod sealing device of the present utility model, realized using the conveyer belt of scrapping as sealed packing, and the material cheapness, reduce costs; Because conveyer belt is embedded with silk thread, so intensity is high, wear-resisting; By the filling container of delivery chute and circular cone bench-type, conveniently the conveyer belt rotating disc is entered or discharge the sealed packing box, easy to use; In addition, owing to can accumulating a certain amount of lubricated butter of using among the triangle gap formed between the conveyer belt be coiled in the sealed packing box, therefore there is good anti-dry grinding performance, long service life.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of having installed on Fig. 1 basis after sealed packing and polished rod.
Illustrate:
The specific embodiment
Following examples are only for the utility model example clearly is described, and are not the restriction to embodiment of the present utility model.For those of ordinary skill in the field; can also make other multi-form variation or changes on the basis of following explanation, and these belong to apparent variation that the utility model spirit draws or change still among protection domain of the present utility model.
As shown in Figure 1, 2, a kind of pumpingh well polished rod sealing device, comprise oil pumping polish rod 10, and oil pumping polish rod is through the filling container 6 of sealed packing box 4, sealed packing 9 is fixed in the filling container 6 of described sealed packing box and wraps up oil pumping polish rod, and described sealed packing 9 is the bar shaped belt; The circular cone bench-type that the filling container of described sealed packing box 4 is downward convergent, the bottom of the filling container 6 of described sealed packing box is provided with righting copper sheathing 1, for aligning oil pumping polish rod.
The middle part processing outer lug boss 801 of sealed packing delivery wheel 8, fix a weld-ring 802 in the upper end of sealed packing delivery wheel 8, described outer lug boss matches with weld-ring and blocks the inner convex platform of pressure cap 7 upper ends and leave end play, and the sealed packing delivery wheel can rotate.On described pressure cap 7, fixed installation handle 701, conveniently turn pressure cap.The bottom of described sealed packing delivery wheel 8 embeds the top of filling container and compresses described sealed packing, the external screw thread interlock on the internal thread of described pressure cap and sealed packing box top; Vertically be provided with the sealed packing delivery chute 803 of inclination on the sidewall of described sealed packing delivery wheel 8, the angle of inclination of described sealed packing delivery chute 803 is 5-30 °, is more conducive to the sealed packing conveying turnover that conveyer belt is made.Described sealed packing 9 is trapezoidal conveyer belt for shape of cross section; The shape of cross section of described sealed packing delivery chute 803 is identical with the shape of cross section of described sealed packing 9.Conveyer belt can use scraps conveyer belt, makes sealed packing, and the material cheapness, reduce costs; Because the conveyer belt kind is embedded with silk thread, so intensity is high, wear-resisting.
Described pumpingh well polished rod sealing device bottom is provided with well head and connects base 1, and the oil inner whorl of base that is connected with well head in the ninth of the ten Heavenly Stems 3 connects, and is fixed on the tuningout base 401 of described sealed packing box 4 lower ends.According to the deviation angle of oil pumping polish rod, at described well head, connect the interior installation righting of base 1 copper sheathing 22.
During use, after the pumpingh well polished rod sealing device is installed, in the sealed packing delivery chute 803 of the sealed packing 9 Self-sealing packing delivery wheels 8 that conveyer belt is made, stretch in the filling container 6 of sealed packing box 4, rotary seal packing delivery wheel 8, be delivered to sealed packing in filling container; After oil pumper starts slightly the time, adjust pressure cap, the press seal packing.
When the sealed packing long term wear, in the situation that not stop pumping, when oil pumping polish rod is descending, till pressure cap is tightened and is adjusted to oil pumping polish rod and is not with oil.
When sealed packing need to be changed, bump off a well, unclamp pressure cap, take out sealed packing, then reinstall new sealed packing according to aforesaid way.
During tuningout, if the polished rod deviation angle is less, by righting copper sheathing two tuningouts, if the polished rod deviation angle is larger, take out the rear tuningout of righting copper sheathing two, this is prior art.
