| Abstract: | A down-hole autotracking well pumping unit different from the conventional pumping unit was designed. This pumping unit fits a down-hole automatic transfer unit controlled on the ground. The working principle of motor-driven control system of the down-hole automatic transfer well pumping unit was analyzed. The matched position and the adjustment techniques for fluid balancing cylinder on the ground with the down-hole working fluid cylinder were analyzed using the down-hole seepage flow theory. The result indicates that the new type of well pumping unit has some good properties such as its simple structure, low cost, working reliability and high efficiency. |
