During the process of sucking viscoelastic fluid, clearance between pump barrel and plunger, and rod tube flow passage lead to the increase of down resistance of the sucker rod, the resistance reduces gradually from the largest value at the bottom to the neutral point, which causes lateral force of the rod string, and results in partial wear.
