Problems solved by technology

Although it has the disadvantages of large acceleration of the suspension point of the donkey head, poor balance effect, low efficiency, large volume and heavy weight, it is still the most widely used pumping unit at present.
[0003] At present, all beam pumping units use motors, cranks, and reducers as driving devices to drive the beams to do periodic reciprocating motions. The mechanism has many large parts and lacks flexibility and precision in control.
It is impossible to accurately control the force of the beam, so the stability of the pumping unit is poor during operation, the system efficiency is not high, and there is a waste of energy. For this reason, we have developed a new energy-saving intelligent beam pumping unit

Embodiment 1

[0033] Such as Figure 1-5 As shown, the embodiment of the present invention provides an energy-saving intelligent beam pumping unit, including a base 1, one side of the upper part of the base 1 is fixedly connected with a support mechanism 2, and the top of the support mechanism 2 is rotatably connected with a beam 3, and the beam 3 One end of the donkey head 4 is fixedly connected, and the donkey head 4 is suspended with a steel wire rope 5, and the steel wire rope 5 is connected with the sucker rod. By setting the donkey head 4 at one end of the beam 3 and the counterweight mechanism 6 at the other end, the beam 3 can be rotated by the supporting mechanism 2 so that the donkey head 4 can swing up and down;

[0034] One end of the beam 3 away from the donkey head 4 is fixedly connected with a fixed seat 7, and a counterweight mechanism 6 is installed on the outside of the fixed seat 7;

[0035] The upper part of the base 1 is connected with a limit swivel seat 8, and the ce...

Embodiment 2

[0042] By designing the traveling balance mechanism 12 to cooperate with the driving mechanism 9, a better balance of the traveling beam 3 can be achieved. The traveling balancing mechanism 12 includes two fixed plates 1201, and both sides of the top of the traveling beam 3 are fixedly connected with the fixed plates 1201, wherein The inner side of a fixed plate 1201 is fixedly connected with a transmission motor 1202, and the top of the output shaft of the transmission motor 1202 is fixedly connected with a transmission screw 1203. Swimming balance block 1204 is installed, and the front and rear ends of the swimming beam 3 top are fixedly connected with the limit slide rail 1205 corresponding to the swimming balancing block 1204, by setting the swimming balance mechanism 12 at the top of the swimming beam 3, and by The transmission motor 1202 drives the traveling balance block 1204 to adjust the relative direction and position of the traveling balance block 1204 on the traveli...

Abstract

The invention provides an energy-saving intelligent beam-pumping unit, and relates to the technical field of petroleum and natural gas exploitation. The energy-saving intelligent beam-pumping unit comprises a base and is characterized in that one side of the top of the base is fixedly connected with a supporting mechanism, the top of the supporting mechanism is rotationally connected with a walking beam, one end of the walking beam is fixedly connected with a horse head, the other end of the walking beam is provided with a fixing base provided with a balance weight mechanism, a limiting rotaryseat driving mechanism is fixedly connected to the base and is arranged between the limiting rotary seat and the walking beam, a moving balance mechanism is arranged at the top of the walking beam, and a buffer damping assembly is mounted on the base. By precisely balancing the walking beam of the pumping unit, energy conservation is achieved, the pumping unit is used for a low-yield well, the stroke frequency is reduced, design redundancy is reduced, a low-power motor is used for driving the pumping unit to work, and besides a conventional industrial power source, solar energy, wind energy and the like can be adopted as supplementary energy for power supply.

Description

technical field [0001] The invention relates to the technical field of oil and natural gas exploitation, in particular to an energy-saving intelligent beam pumping unit. Background technique [0002] The pumping unit is the most important lifting equipment in the rod pumping system, and the number of beam pumping units accounts for a large proportion. The basic characteristics of the beam pumping unit are large structure, reliable operation, easy operation and maintenance. convenient. Although it has disadvantages such as large acceleration of the suspension point of the donkey head, poor balance effect, low efficiency, large volume and heavy weight, it is still the most widely used pumping unit at present. [0003] At present, all beam pumping units use motor, crank, and reducer as the driving device to drive the beam to do periodic reciprocating motion. The mechanism has many large parts and lacks flexibility and precision in control. It is impossible to accurately contr...
