Shengji API 11B oil well pumping unit rod rotator oil well sucker rod rotator
Shengji API 11B oil well pumping unit rod rotator oil well sucker rod rotatorr
Product DescriptionIn the sucker rod pump oil production system, the reciprocating motion of the sucker rod in the tubing causes the intense friction between the sucker rod and the tubing, which leads to the fracture of the sucker rod and the perforation of the oil pipe. More serious in partial deviated wells and horizontal wells. Shengji rod rotator produced by Shengji integral tubing Rotator manufacturer can make the sucker rod rotation at a constant speed, so that the sucker rod and tubing wear will be distributed in the range of 360 degrees, reduce eccentric wear, so as to prolong the service life of the sucker rod and tubing and reduce the production cost.
1. Reduce eccentric wear and prolong the service life of the sucker rod and tubing.
2. Compact structure, small size easy to install.
3. Allow the rod to rotate at a steady speed.
4. Low speed and heavy load, do not affect normal oil production.
5. Applicable to various types of pumping units.

Basal Principle
The rod rotator is on top of the hanger, and the sucker rod is right through its center bore. What's more, it top is with the polish rod clip. At a certain position in the down stroke the pull rope between the pumping unit horsehead and the rotor pull the actuator level to turn a certain angle. At the moment, the rachet pawl drive worm drive shaft and worm gear will turn a certain angle in a clockwise direction , and so that the worm will also turn a certain angle. As a result, the cover cap turns a certain angle, too. The polish rod clip makes the gravity of the sucker rod string act on the cover cap, so the sucker rod can also turn a certain angle. In the up stroke, the pawl can be relocated by the actuator level gravity.
