The use of composite materials in the elements of the beam-balanced pumping unit

The article discusses the potential of using composite materials in the construction of the beam-balanced pumping unit. Traditionally, these constructions are made from steel with high strength and reliability. However, modern requirements for energy efficiency and cost reduction encourage to active search for alternative solutions. One such solution is the use of composite materials with several significant advantages: low density, high specific strength, corrosion resistance, and the ability to withstand aggressive environments. As an optimal solution, the authors of this article suggest hybrid elements — traverse, connecting rod, and beam. These elements are made from composite profiles with metal inserts in the fastening zones and connected using bonded-bolted joints. Use of hybrid elements ensures both reliable connections and the material's opportunity to interact with different physical and mechanical properties. The article particularly focuses on construction features of metal-composite joints and their potential resistance to bending and tensile loads. The authors further enumerate limitations to the use of composites: high cost, sensitivity to temperature effects, and complexity of repairs. Nevertheless, they consider the combination of composite and metal components as a promising line of development that may enhance the efficiency and durability of equipment in the oil production industry. The article serves as a review of the design phase without a detailed calculation section.
