Application of seals made of directed reinforced polymeric composite materials to improve wear resistance of friction units of oil well pumps

[摘要] Here we deal with the perspectives of advanced materials application to improve wear resistance of oil well pumps friction units, in particular, cup packing materials. We present results of wear resistance estimation of some polymeric composite materials with differently directed strengthening (chaotically, perpendicular and parallel to friction forces). Composite materials based on advanced polymers: nylon plastic, polysulphone, polyethylene, polyethylene terephthalate. Dispersed graphite, carbon fiber, dispersed (1 mm) carbon fiber, synthetic high-modulus fibers were used as fillers. The results showed that in friction units of oil well pumps contacting with raw oil it is rational to use seals made of composite materials based on polyamide, strengthened with synthetic high modular fibers perpendicular to the fiction surface.
