Abstract

The invention relates to a vertical energy-saving pumping unit. The pumping unit comprises a motor, a motor dragging device, a gravity distributor, a beam hanger self-balancing system, a balance weight and a pumping rod system which are installed on a base, wherein the pumping rod system is connected with the balance weight by the beam hanger self-balancing system installed at the upper end of a support; the balance weight is connected with the gravity distributor; the gravity distributor is connected with the motor dragging device by a steel wire rope; a dynamic centering device for centering the steel wire rope is installed between the motor dragging device and the gravity distributor; the gravity distributor is formed by installing upper and lower pulley blocks on a supporting frame; the upper pulley block is a movable pulley block and can slide up and down along the supporting frame; the lower pulley block is a fixed pulley block and is fixed on the supporting frame; the steel wire rope is sequentially penetrated through the upper pulley block and the lower pulley block; and the motor dragging device is a reversible drum. After the difference of the weight of the pumping rod system and the weight of the balance weight is decomposed by the gravity distributor, a motor is used for providing the dynamic force corresponding to the difference, so the power of the motor matched with the motor dragging device is low, thus achieving the effect of electricity and energy saving.

Description

[0001] This application is a divisional application of the invention patent application "vertical energy-saving oil pumping unit". The invention name of the original application is: vertical energy-saving oil pumping unit, the application date is June 19, 2008, and the application number is: 200810110975.4. 1. Technical field: [0002] The invention relates to an oil pumping unit used in oil exploitation, in particular to a vertical energy-saving oil pumping unit. 2. Background technology: [0003] In the process of oil extraction, it is necessary to use a pumping unit to pump crude oil up from the ground. With the continuous advancement of technology, the vertical pumping unit omits the crank-link mechanism, beam, beam, and donkey of the traditional beam pumping unit. The first-class mechanism reduces mechanical loss and achieves energy-saving effects to varying degrees, and is gradually being applied. For example, a Chinese utility model patent whose patent number is ZL200...
