Oil Downhole Fluid Discharged From Guide Cage Flushes Sand Sedimentation Away Rod Inseted Pump
Oil downhole sucker rod series rod inseted pump description:
The RHAC/RHAC series pump barrel is mounted to the top by a bracket. The rod pump is suitable for sand production Wells and oil Wells, due to the discharge of fluids will wash away from guide cage between tubing and pump at the top of the sand will make it easier for pump barrel under the internal pressure caused by the liquid column and the influence of the tensile load, when the piston clearance on the stroke will increase, so do not recommend the use of this kind of top anchor in deep well pump when rod pump operation, The vertical valve at the bottom of the pump is easily immersed in the well fluid, which is suitable for low liquid level Wells. The top anchor mode keeps the pump in free suspension and has self-alignment effect, which is suitable for deviated Wells.
The pump is more suitable for heavy oil Wells than the bottom bolt insertion pump. However, due to the internal pressure and tension caused by the fluid column, the pump barrel is likely to expand and increase the plunger clearance, so it is not suitable for deep Wells.
