Abstract

The invention relates to an oil pumping unit. The oil pumping unit comprises a horse head, a girder beam, a bracket, high-pressure springs, a cross beam, connecting rods, a crank, a reduction box and a motor. The horse head is fixedly connected with one end of the girder beam to be integrally formed. The middle section of the girder beam is rotationally connected with the top end of the bracket through a rotating shaft. The other end of the girder beam is rotationally connected with a middle protrusion of the cross beam through a rotating shaft. One end of one of the two high-pressure springs is fixedly connected with one end of the girder beam. The other high-pressure spring is fixedly connected with the other end of the girder beam. The other ends of the two high-pressure springs are fixedly connected with protrusions at the top ends of two long plates stretching out of the front side and the back side of the bracket correspondingly. According to the oil pumping unit, the energy utilization rate and production benefits are increased; the loading condition of suspension points can be improved, and the loading condition of the motor is relieved; the balance degree of the oil pumping unit is improved, and inverse torque is eliminated or weakened.

Description

technical field [0001] The invention relates to an oil pumping product, in particular to a pumping unit. Background technique [0002] At present, various manufacturers at home and abroad have successively developed pumping units such as front-mounted pumping units, out-of-phase crank pumping units, and air-balanced pumping units, which have overcome some shortcomings of conventional beam pumping units to varying degrees. But still can not get rid of the use of four-bar linkage to transform the rotary motion into linear reciprocating motion, resulting in the pumping unit balance effect has not been fundamentally improved, the acceleration is still high, the inertial load is large, and the total mass is doubled. Therefore, there is no It solves the fundamental problem, and makes the structure more complex, which increases a certain burden on repair, maintenance, and service life. [0003] At present, the pumping unit consumes a lot of electricity, and the work efficiency and...
