The two reducers in the device must ensure the coaxiality, center height, parallelism with the bottom surface and other key dimensions of the output shafts at both ends of the whole device, and must be installed and positioned quickly and accurately. At the same time, it must meet the requirements of connecting and fixing the whole device to the original oil pumping unit without changing the size of the original oil pumping unit base. Therefore, the structural design of the base is directly related to the rapid and accurate assembly of the whole device and the oil pumping unit and the normal operation of the oil pumping unit.
