Embodiment Construction

[0012] Below in conjunction with accompanying drawing and example the present invention will be further described:

[0013] Such as figure 1 As shown, a new type of pumping unit includes: donkey head 1, traveling beam 2, support 3, high-pressure spring 4, crossbeam 5, connecting rod 6, crank 7, reduction box 8 and motor 9, and described donkey head 1 and traveling beam One end of beam 2 is integrally formed, the middle section of beam 2 is rotationally connected with the top of bracket 3 through a rotating shaft, the other end of beam 2 is rotationally connected with the protrusion in the middle of beam 5 through a rotating shaft, and one end of two high-pressure springs 4 is fixed through a The other end of the two high-pressure springs 4 is fixedly connected to the other end of the beam 2 by means of fixed connection, and the other ends of the two high-pressure springs 4 are respectively connected to the bracket 3 by means of fixed connection. The tops of the two long board...

Abstract

The invention relates to a novel pumping unit which comprises a donkey head, a swinging beam, a support, high-pressure springs, a beam, a connecting rod, a crank, a speed reducing box and a motor. The donkey head is fixedly connected with one end of the swinging beam to be integrally formed, the middle section of the swinging beam is connected with the top end of the support through a rotating shaft in a rotating mode, and the other end of the swinging beam is connected with a protrusion in the middle of the beam through a rotating shaft in a rotating mode. One of the two high-pressure springs is fixedly connected with one end of the swinging beam in a fixedly connected mode, the other high-pressure spring is fixedly connected with the other end of the swinging beam in a fixedly connected mode, and the other ends of the two high-pressure springs are fixedly connected with protrusions at the top ends of two long boards extending out of the front side and the back side of the support in a fixedly connected mode. By means of the novel pumping unit, the utilization rate of energy is improved, production effectiveness is increased, the loading conditions of suspension points can be improved, the loading conditions of the motor can be relieved, the balancing degree is improved, and the negative torque is eliminated or weakened.

Description

technical field [0001] The invention relates to an oil pumping product, in particular to a novel 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 power, and the work efficiency and...
