Research On Adaptive Balance Block Device For Beam Pumping Unit

Conventional beam pumping unit, as the most common mechanical oil production equipment in domestic and overseas oilfields, has great torque fluctuation on the motor output shaft in view of its suspension load characteristics and its own structure. In this paper, according to the C-320D-256-100 conventional beam pumping unit which is currently in use, it is proved that the pumping unit has the advantages of low cost, low energy consumption and low cost. Increase the adaptive balance weight mechanism, so that the balance block with optimal balance function, make its structure more reasonable.In this paper, the basic theory of the conventional pumping beam pumping unit is sorted out, and the dynamic analysis of the four-bar linkage mechanism of the pumping unit is carried out by using the instantaneous center of velocity method, and the corresponding formulas are established according to the dynamic analysis of the suspension load and the equilibrium load. C-320D-256-100 pumping unit adaptive balance block scheme and principle, in order to obtain the rationality of the design parameters in the program, according to the kinematics and kinetic formula of the pumping unit MATLAB program analysis, and to obtain The optimal value of the parameters of the balance, the reducer for the objective function of the minimum RMS value of the improved structure and the original comparison, to achieve the purpose of effective energy saving, other indicators are also within the specified range. Finally, a brief statement is given to the mechanical design and electrical engineering. After analyzing the necessity of the finite element analysis of the crank, the finite element software of SolidWorks Simulation was used to analyze the key parts before and after the transformation. Through the stress cloud and strain cloud comparison, we can see that after the new mechanism, The maximum stress and the maximum strain of the crank are reduced compared with that before the reformation, and the feasibility of the new scheme is proved from the aspects of mechanics.Through this device, the balance of pumping unit can be improved to a certain extent after the transformation, and the working efficiency of balance adjustment of pumping unit can be improved by 11.5%, and the safety factor of key components is improved. For the traditional pumping unit, the energy saving and consumption reduction is certain. Reference and reference.
