The invention discloses an accessory used for guiding a sucker rod. The accessory comprises an outer shell, an outer ring, pulley wheels and a fastening component, wherein the main body of the outer ring, the pulley wheels and the fastening component are all arranged in the outer shell, the outer ring is provided with notches along the peripheral direction, the notches are used for arranging the pulley wheels, the upper parts of the pulley wheels extend out of the outer ring to guide the sucker rod, the fastening component is arranged in the outer ring, fastening force can be generated by the fastening component, and the accessory and the sucker rod produce a good fixing effect. The invention discloses the accessory used for guiding the sucker rod, the accessory is reasonable in structural design and has a unique effect, the number and the positions of accessories on the sucker rod can be determined according to the length of the sucker rod and the actual working condition, and the installation and the operation of the accessories are convenient; and at the same time, the stability of the accessory is outstanding, the accessory has a good guiding effect, the working stability of the sucker rod can be effectively improved, and the service life of the sucker rod is prolonged.
Description
technical field [0001] The invention relates to a sucker rod fitting, in particular to a new type of guide fitting that can effectively improve the working stability of the sucker rod, and belongs to the technical field of oil fittings. Background technique [0002] The sucker rod is a hollow and slender rod, which is connected to the main rod at the top and the oil well pump at the bottom, which mainly plays the role of power transmission; The buckles are connected one by one, and extend to the piston at the underground oil layer, and the oil is pumped by reciprocating up and down. [0003] During the reciprocating movement of the sucker rod up and down in the oil pipe, due to the pressure of the oil and the actual condition of the pipeline, there will be collision and friction with the oil pipe, which reduces the service life and working stability of the sucker rod. Usually, people will install centralizers on adjacent sucker rods, but the centralizers can only be install...
