Abstract
A kind of pumping well polish rod packing assembly, comprising: spring base (1), bolt (2), spring (3), packing seat (4), packing (5), screw rod (6), gripper shoe (7), jackscrew (8); It is characterized in that: the spring (3) of described pumping well polish rod packing assembly is contained in the ladder hole (A) of spring base (1), the edge of spring base (1) is arranged with bolt (2), bolt (2) is equipped with successively packing seat (4), packing (5), packing seat (4), gripper shoe (7), the screwed hole of centre of gripper shoe (7) is built with jackscrew (8).The utility model is applicable to not stop production and changes packing polished rod sealer, and packing is from operation when fastening, and easy to operate, spring force is large, can automatic feed, and service time is long, good sealing effect, avoids crude oil loss and contaminated environment.
Description
Technical field
the utility model relates to oil-field oil pumper wellhead polish rod sealed packing structure technology, specifically a kind of pumping well polish rod packing assembly.
Background technology
in process of production, wellhead polish rod sealing is key technology to oil field machinery oil pumpingh well, and packing kind is more, have ring-like, tapered, the replacing packing that do not stop production have also been obtained extensive use, but this packing needs both sides to operate when fastening, operation inconvenience, spring force is little, can not automatic feed, service time is short, and sealing effectiveness is poor, the easy leakage of oil of well head, causes crude oil to lose and contaminated environment.
Summary of the invention
the purpose of this utility model is exactly in view of the foregoing defects the prior art has, designs a kind of pumping well polish rod packing assembly.
the utility model is realized by following technical proposals:
pumping well polish rod packing assembly, comprising: spring base, bolt, spring, packing seat, packing, screw rod, gripper shoe, jackscrew.The spring of described pumping well polish rod packing assembly is contained in the ladder hole of spring base, and the edge of spring base is arranged with bolt, and bolt is equipped with successively packing seat, packing, packing seat, gripper shoe, the screwed hole of centre of gripper shoe is built with jackscrew.
packing seat center in above-mentioned pumping well polish rod packing assembly is provided with through hole, and edge is arranged with bolt hole, and an end face periphery is provided with annular flange flange.
packing in above-mentioned pumping well polish rod packing assembly is cylindrical, for two halves structure, centre is provided with polished rod through hole, polished rod through hole central vertical is in the center of packing, center-line joint is square waveform, and the center, two ends of packing is respectively provided with a screw rod, is convenient to dismounting, edge is arranged with bolt hole, and two ends circumference is arranged with twice annular flange flange and cylindrical shape boss.
jackscrew center in above-mentioned pumping well polish rod packing assembly is provided with blind hole, is provided with external screw thread, is provided with six square toes outside the annular boss of termination.
the beneficial effects of the utility model are: be applicable to not stop production and change packing polished rod sealer, and packing is from operation when fastening, and easy to operate, spring force is large, can automatic feed, and service time is long, good sealing effect, avoids crude oil loss and contaminated environment.
Accompanying drawing explanation
fig. 1-the utility model master is depending on partly cuing open structural representation.
in figure, 1. spring base, 2. bolt, 3. spring, 4. packing seat, 5. packing, 501. flanges, 6. screw rod, 7. gripper shoe, 8. jackscrew, 801. six square toes; A. ladder hole, B. through hole, C. polished rod through hole, D. tapped through hole, E. blind hole, F. bolt hole.
Detailed description of the invention
below in conjunction with accompanying drawing, enforcement of the present utility model is further elaborated:
pumping well polish rod packing assembly is made up of spring base 1, bolt 2, spring 3, packing seat 4, packing 5, screw rod 6, gripper shoe 7, jackscrew 8.The spring 3 of described pumping well polish rod packing assembly is contained in the ladder hole A of spring base 1, the edge of spring base 1 is arranged with bolt 2, bolt 2 is equipped with successively packing seat 4, packing 5, packing seat 4, gripper shoe 7, the screwed hole of centre of gripper shoe 7 is built with jackscrew 8.During use, pumping well polish rod packing assembly is loaded in polished rod sealer, polished rod passes from polished rod through hole C, block six square toes 801 of jackscrew 8 with box spanner, rotate clockwise box spanner, suitable fastening jackscrew 8, packing 5 is under the elastic force effect of spring 3, along with the wearing and tearing of polished rod and packing, automatic feed, thus sealing function is played to polished rod.
