Abstract

The invention relates to a vertical energy-saving pumping unit which includes a motor, a motor actuator, gravity distributors, a self-balance system for polished rod eyes, a balance weight and a sucker rod system, which are arranged on a base. The balance weight is connected with one gravity distributor through a lifting system, and the sucker rod system is connected with another gravity distributor through the self-balance system for polished rod eyes, and the two gravity distributors are connected with the motor actuator through wire ropes. A dynamic righting device for righting the wire ropes is arranged between the motor actuator and the gravity distributors. Each of the gravity distributors is formed by installing an upper and a lower group of pulleys on a support frame, wherein the upper group is a movable pulley group and the lower group is a fixed pulley group. The wire ropes pass through the upper and the lower group of pulleys sequentially. The motor actuator is a reversibleroller. The motor can provide the power corresponding to the weight difference between the sucker rod system and the balance weight after the weight difference is decomposed by the gravity distributor, so the motor power of the motor actuator is very small, thus saving electric and energy.

Description

1. Technical field: [0001] The invention relates to a pumping unit used in oil exploitation, in particular to a vertical energy-saving pumping unit. 2. Background technology: [0002] 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 ZL200620088857.4 and whose patent name is "a vertical pumping unit" discloses a vertical pumping unit. It is composed of reducer, driving drum and polished rod of the pumping unit connected to the motor; the driving drum is wrapped with a tape flexible object, one end of which is connected to the polished rod of the pumpin...
