Abstract
The utility model discloses a polished rod stuffing box for sucker rod pumping unit for oil recovery and capable of error correction and direction regulation, and comprises an adapter, a connection screw bolt, a packing box, a stuffing and a gland. A direction-regulating disc, with tilting end surface, is arranged between the adapter and the packing box. The tilt angle of the tilting end surface of the direction-regulating disc matches with the offset of included angle between the central lines of the packing box and the adapter. The direction-regulating disc is constituted by vertically-overlapped upper and lower direction-regulating discs (each with tilting end surface), the upper and lower direction-regulating discs rotate around the central line, so that the two tilting end surfaces form a certain angle to match with the offset of an angle produced by the alignment of central lines of the packing box and the polished rod of pumping unit, leading to the alignment of central lines of the packing box and the polished rod of pumping unit. Accordingly, the utility model can avoid the eccentric wear of stuffing, prolong the service life of stuffing, reduce the frequency of changing stuffing, reduce the labor intensity, and increase the production efficiency of pumping unit.
