Two Days of the Wheels of the Horizontal Angle Change Impact Study of 12 Type Rack Pumping Unit Frame

With the continuous progress of the oil production technology, the pumping unitfrom the original beam pumping unit has gradually developed into a non-beam pumping unit. Long annular rack pumping unit is a kind of non-beam pumping unit. Studying for the overall stress of the 12 type long ring rack pumping unit, When the diameter of theup sky wheel is equal to the diameter of the before sky wheel. The influence of the ang-le between the connecting line and the horizontal plane on the whole stress state, deform-ation and stability of the frame is two sky wheel. According to the basic parameters of t-he oil machine type 12 long ring gear rack pumping determined the pumping unit's overa-ll size, then carries on the stress analysis to the wheel for two sky wheel, for horizontal and vertical component of their respective, using SolidWorks to 12 long ring rack pumpin-g oil machine modeling, then will be built model were introduced into ANSYS Workbenc-h. Finally to mesh, applied load, fixed constraint, solve with the model. As can be seen from the results, when the two days of the wheel core connection and the angle between the horizontal plane changes, it will cause the overall stability of the rack, stress, deform-ation, strength, etc. With the increase of the angle, the equivalent stress and total deform-ation of the frame will be increased, and the stability of the frame will be reduced.
