Eagle Innovations company to make technical improvements to develop a way to solve the problem of wear and corrosion, which introduced a new generation of underground pumps. Apply a new "E" -CARBON coating to the surface of the pump element - a thin and dense patented material that greatly extends pump life. The new surface coating has a hardness of 92 + Rc, which gives oil tool designers and fabricators the opportunity to optimize the performance of downhole pumping equipment. The coating does not break or separate from the base metal surface. Impact bending and normal bending operation will not make the coating fragmentation, fall off. It operates successfully at temperatures up to 1400 ° F (775 ° C) without adversely affecting the integrity of the coating and base metal. The coefficient of friction of the opposite and contact surfaces of the metal coated with the new method is significantly reduced. Applying new materials to pump components such as bushings, plungers, ball and valve seats that are subject to sliding and moving contact can virtually eliminate the problem of wear and erosion, making installation and removal much easier. Coating can be evenly distributed on the surface, and can closely control the thickness of the metal deposit error, the range controlled at 0.001 ~ 0.002in. Other advantages include: 1, can be coated on all the base metal alloy; 2, good corrosion resistance; 3, with the substrate to form a whole, will not be broken or fall off. It can be applied to: (1) all base metal such as ball / seat, sleeve and plunger; (2) stem and core; (3) thread (ID and OD); (4) Bearing; (5) PC pump wheel; (6) spoiler. Developers claim that the system can basically be applied to all pump components.
