... the well head, and is an optimal solution for rod-lift production of low-volume wells. For the chain drive body, double tee profiles with parallel faces are used, which serve as both a support structure and balance weight guides. The paper presents technical characteristics of the new-design chain drive in comparison to PTs 30 model chain drive developed by the Bugulma Mechanical Plant, as well as a case study. The authors analyze technical solutions and consider ways to improve the chain drive ...
