| titleOfInvention | NEW AND IMPROVED DESIGN OF ELECTRIC SUBMERSIBLE PUMP ENGINE |
| abstract | 1. Submersible pump motor comprising:! rotationally mounted shaft! sleeve connected to the shaft! rotor section connected to the shaft! casing containing the shaft, sleeve and rotor section,! the stator section located in the casing and connected to it, and! a cylindrical bearing housing coupled to a sleeve housed in it, located in the housing and connected to it,! moreover, at least the sleeve or bearing housing has a coating consisting of nickel boron. ! 2. The submersible pump motor according to claim 1, in which the sleeve is made of a material selected from the group comprising bronze 62, bronze 660 and AISI 1018-1040 steel. ! 3. The submersible pump motor according to claim 1, wherein the bearing housing is made of nitralloy. ! 4. The submersible pump motor according to claim 1, wherein the nickel-boron coating is obtained by non-electrochemical deposition. ! 5. The submersible pump motor according to claim 1, in which the percentage of the coating of nickel-boron by weight of 4.5-7.0% is boron, and the rest is nickel. ! 6. The submersible pump motor of claim 1, wherein the nickel boron coating thickness is about 0.00075 inches. ! 7. The submersible pump motor according to claim 1, wherein the RMS roughness (RMS) of the treated nickel-boron coating surface is a maximum of 8-16. ! 8. A bearing assembly for a submersible pump motor comprising a shaft having a rotor section connected to it and a casing having a stator section connected to it and containing a shaft, the bearing assembly comprising:! a sleeve adapted for connection to a rotatable shaft, and! a cylindrical bearing housing associated with a sleeve housed in it and adapted |
