Sucker Rod for Screw Pump Drive
價(jià)格：元
The Sucker Rod for Screw Pump Drive is a newly developed special sucker rod by our company, specifically designed for surface-driven screw pump oil extraction systems. This new sucker rod enhances the strength of the rod string and improves the reliability of the connection points, reducing common failures such as rod breakage, thread loosening, and pushing incidents.
There are two types of screw pump drive rods: solid and hollow. The connection structures are as follows (refer to Figures 1 and 2 for connection structures):
1.Double-shoulder straight thread structure
2.Wedge-shaped spigot left-hand thread structure
