Abstract
The utility model provides an improved automatic core-regulating and direction-regulating polish rod sealer, which is suitable for pumping unit oil extraction wells. The utility model is provided with two-stage packing sealing, the first-stage sealing at the upper part is arranged in a spherical packing box, and the spherical packing box is pressed and sealed by a ball sealer base which is fixed between a top and a bottom slide plates. The sealing packing can automatically adjust direction with the spherical packing box and can automatically adjust core with the slide plates. Therefore, the utility model can overcome various errors between the polished rod and the well mouth, prevent eccentric wear, enhance the service life of the sealing packing and reduce the change time of the packing. When the packing need to be changed, a second-stage packing at the lower part can be tightly pressed for preventing oil leakage, so the cleanness of the well mouth can be kept.
Description
The utility model relates to a kind of automatic aligning tuning polished rod sealer, is specially adapted to the pumping production well.
The sealed packing that existing polished rod sealer matches with polished rod can not the aligning tuning, when being used for pumping production, because the mismachining tolerance of oil pumper foozle, alignment error, drilling well gradient error, wellhead for production etc., the polished rod axis that causes oil pumper to hang does not overlap with the axis of well head, and polished rod is when pumping, make polished rod sealer packing generation eccentric wear, make seal failure, produce leakage, cause and frequently to change packing, influence the ordinary production of oil well, contaminated environment.
The purpose of this utility model provides a kind of improved polished rod sealer, the center of its sealed packing, orientation angle can be regulated within the specific limits automatically, make sealed packing all the time with the dead in line of polished rod, overcome the eccentric wear phenomenon, reduce packing and change number of times, guarantee the oil well ordinary production, keep the well head cleaning.
The utility model is achieved in that and is provided with the two-stage sealed packing in polished rod sealer, the I level sealed packing on top is installed in the spherical sealed packing box, spherical packing box compresses sealing by being fixed on two sealed ball seats on the sliding plate, sealed packing can be adjusted direction automatically with spherical packing box, automatically planar adjust the center with sliding plate, prevent the packing eccentric wear, the II level packing of bottom is contained in sliding plate and the slip lock collar, II level sealed packing can be in sliding plate adjustment center automatically.
The utility model novel structure, reliable, the packing long service life of sealing.
The utility model is provided by following examples.
Figure one is the utility model structural representation.
Describe concrete structure of the present utility model and operating principle in detail below in conjunction with accompanying drawing:
With reference to figure one, oil pumper is when operate as normal, polished rod ［ 1 ］ is by I level sealed packing ［ 9 ］ sealing on polished rod sealer top, packing ［ 9 ］ is fixed in the spherical packing box ［ 8 ］, spherical packing box ［ 8 ］ is by being fixed on sliding plate ［ 6 ］, ［ 11 ］ the spherical up and down seal receptacle ［ 7 ］ on, ［ 10 ］ compress sealing, when polished rod ［ 1 ］ when axis departs from, packing ［ 9 ］ can be with spherical packing box ［ 8 ］ at spherical packing seat ［ 7 ］ up and down, ［ 10 ］ adjust direction in automatically, with sliding plate ［ 6 ］, ［ 11 ］ adjust the center automatically, thereby realize sealed packing ［ 9 ］ aligning tuning.Spherical packing box ［ 8 ］, compress by bolt ［ 14 ］ by gland ［ 12 ］, sealed packing ［ 9 ］ is taper, seal thrust by regulating sleeve ［ 13 ］ by threaded adjusting, frizing packing ［ 17 ］ is equipped with on regulating sleeve ［ 13 ］ top, and frizing packing ［ 17 ］ is compressed by bolt ［ 16 ］ by pressure cap ［ 19 ］, in the annular housing of regulating sleeve ［ 13 ］ and polished rod ［ 1 ］, can pass through oil nozzle ［ 15 ］ and inject butter, improve the working condition of packing.
Be provided with II level sealed packing ［ 2 ］ in the bottom of polished rod sealer, sealed packing ［ 2 ］ is contained in sliding plate ［ 3 ］ and the slip lock collar ［ 4 ］, regulates degree of tightness by slip lock collar ［ 4 ］, when polished rod ［ 1 ］ operate as normal, unclamp jackscrew ［ 5 ］, sealed packing ［ 2 ］ does not seal; When polished rod departed from, sealed packing ［ 2 ］ can move with sliding plate ［ 3 ］ ［ 4 ］, adjusts the center automatically, prevents eccentric wear; When needs are changed I level sealed packing ［ 9 ］, locking jackscrew ［ 5 ］, jackscrew ［ 5 ］ promotes slip lock collar ［ 4 ］, compresses II level sealed packing ［ 2 ］, realizes sealing; When playing lower sucker rod, the weight that support ［ 18 ］ can bear sucker rod is in case the sealing of pressure ring I level.
