The lateral wall of the positioning tie bar is equipped with compression spring, and centralizer is additionally provided on the polished rod, and the oil-extractor polish-rod after answering is several
What precision is high, and the technological means of processing can be such that outside stainless steel is filled into automatically at the sucker rod shortcoming being corroded, to not
Stay any gap.The application of Corrosion of Stainless Steel sucker rod substantially prolongs the safe handling period of well mouth sealing device.
Further, the compound sleeve material is stainless steel.
Further, the side of the polished rod is equipped with packing box, and the packing box is equipped with circular hole corresponding with polished rod.
Further, the sealed plunger is equipped with sealing column consent, and the lateral wall of the polished rod is matched with plunger hole.
Further, the envelope fat pier of gas is equipped in the positioning device.
Further, the positioning device side is equipped with lubrication oil filler point.
Further, it is additionally provided with universal joint gum cover on the outside of the polished rod.
The advantages of the present invention over the prior art are that：Oil-extractor polish-rod geometric accuracy after reparation is high, the skill of processing
Art means can be such that outside stainless steel is filled into automatically at the sucker rod shortcoming being corroded, to which what gap do not remained in office.Stainless steel
The application for corroding sucker rod, substantially prolongs the safe handling period of well mouth sealing device, and oil, vapour, water is effectively inhibited to let out
Dew makes the subduction pollution of well site periphery, ecological environment be protected.
