Abstract
The article investigates the problem of determining the number of swings of the rods suspension point of the new constructive solution of the sucker-rod pumping unit in the lowspeed operation mode. It was determined that this small value of the speed causes a decrease in the maximum kinetic energy caused by the mechanical transmission of the rod well pump, and therefore, considering this energy parameter of the system as an analyzed parameter is of great practical importance. Therefore, in the article, as a criterion for the low-speed operation mode, a comparison of the maximum kinetic energy of the pumping unit and the useful energy spent on lifting of the liquid from the well was proposed. It was determined that with the increase in the diameter of the plunger, the useful energy used on lifting the liquid from the well increases, and accordingly, the share of kinetic energies in the total used energy balance increases accordingly.
