Well pumping apparatus with lubrication cups for drive string rod
A recently granted patent (Publication Number: US11982286B2) discloses a novel well pumping apparatus designed to improve efficiency and longevity. The apparatus includes a discharge head, a drive string rod connected to a production tubing, pre-lubrication ports at the discharge head, and lubrication cups installed along the drive string rod adjacent to sets of bearings. The use of non-metallic bearings, specifically fluoropolymer bearings, enhances the performance of the apparatus, with the option of reinforced fluoropolymer for added durability.
Furthermore, the patent details a method for maintaining the apparatus, involving the application of a non-aqueous lubricant to the bearings while the drive string is stationary, followed by activating a motor to rotate the drive string. The continuous flow of material rising in the production tubing, such as water or an edible oil-based lubricant, ensures ongoing lubrication of the bearings. This innovative approach not only simplifies maintenance but also contributes to the overall efficiency and reliability of the well pumping apparatus, showcasing advancements in the field of oil extraction technology.
