The height of the pumping unit suction pipe inlet relative to the riverbed bottom

One of the solutions to reduce the production and maintenance costs of the sucker rod pumping installations is to develop automated systems for regulating and controlling their operations. The development of these automated systems requires an attentive modeling of the dynamics of the mechanism of the pumping unit, process in which the identification of the values of the parameters involved in the calculations plays an essential role. The paper presents the manner of determining the values of some parameters of the mechanism of a C-320D-256-100 pumping unit starting from the variation on a cinematic cycle of the motor torque at the crank shaft. Simulations were performed with a computer program developed by the authors, and the experimental records were processed with the program Total Well Management.

Polished Rod

The paper presents the results of theoretical modeling of joined movement of pump rods and plunger pump and multiphase flow in a well for determination of dynamic loads on the polished rod of pumping unit. The specificity of the proposed model is the possibility of taking into account for complications in rod pump operating, such as leakage in valve steam, presence of gas and emulsion, incorrect fitting of plunger inside the cylinder pump. The satisfactory agreement of results of the model simulation with filed measurements are obtained.

The effect of hydrogenation conditions on rate of hydrogenation of rape seed oil was studied in a laboratory stirred tank reactor of 250 ml volume, with nickel on kieselguhr catalyst within the range of conditions (150 ⪬ t(°C) ⪬ 190), (0.1 ⪬ P(MPa) ⪬ 1.0), and (0.01 ⪬ cNi(%) ⪬ 0.37). On the basis of these results a comparison of the effect of a Venturi tube and single pipe gas inlet as gas distributors on hydrogenation rate was made in a bench scale unit of 5 l volume.
