As we know in Azerbaijan, oil production is carried out both in the offshore and onshore. Offshore production is carried out on special platforms, while the onshore exploitation carried out directly by a mechanized method. This downhole pumps consist of a surface mechanical transmission and downhole equipment. For direct mechanization of ground equipment, a device called rocking machine is used, consisting of transmission and converting mechanisms. The main task of the rocking machine is to ensure the conversion of the rotational motion of the engine into the up and down stroke of the plunger of the pump. The downhole equipment includes rods column that lift liquid from the well, a cylinder and a plunger. The main object of study of the report is the strength condition of the rod column, which is one of the operational and technological characteristics of the rocking machine. As a result of the research carried out in the report, a mathematical expression was proposed to determine the linear density of the liquid column, which satisfies the condition of the strength of the rod string, in order to clarify the areas of application and ensure the safe operation of the rocking machine. This formula can be applied not only to the existing classic rocking machines, but also to other new design of rocking machines.
