Abstract
This paper presents a rack-and-pinion pumping unit. A type of SRD (switched reluctance driver) motor is utilized as the driving unit of the pumping unit. The rotation direction of the output shaft of the motor can change automatically, without reversing mechanism，so it can directly dive the gear box and then drive the rack-and-pinion in which the rack connected with the suck rod. Additionally, a super capacitor unit and control unit of charge and discharge is used to design the balance of the pumping unit. Due to the special balance design and no crank-rocker mechanism in the rack-and-pinion pumping unit, it has features of simple structure, less floor area, well balanced and high running efficiency. The most important is that the stroke and number of punching can be adjusted in a wide range which can adapt to different oil wells.
