Abstract
The invention discloses a kind of gravity-driven oil pumper, described oil pumper includes walking beam, hinge, pouring weight, Electric Traction mechanism, support and sucker rod, described hinge is arranged on the upper end of support, described walking beam is rack-mount by hinge, the front end of described walking beam is connected with sucker rod, walking beam is provided with guide rail and sensor, described walking beam swings up and down in vertical direction with hinge for fulcrum, described pouring weight is made tandem by Electric Traction mechanism on guide rail and is moved, when pouring weight is moved rearwards by, pouring weight drives walking beam to make clockwise and swings, realize Pumping action, when pouring weight moves forward, walking beam is made counterclockwise to swing, sucker rod moves downward.The oil pumper of the present invention is two bar pumping units, without belt pulley and reductor, has efficiency high, the advantages such as energy consumption is low, and simple in construction is easy to operate, and cost is low.
Description
Technical field
The invention belongs to oil exploitation mechanical field, be specifically related to a kind of gravity-driven oil pumper.
Background technology
The beam pumping unit being applied to oil extraction in oil field at present mainly has two classes: a class is traditional driven by motor reductor
The beam pumping unit of transmission, another kind of is the permanent magnet direct driving motor beam pumping unit without reductor developed in recent years.
The beam pumping unit of traditional driven by motor deceleration transmission, its structure is that asynchronous motor passes through belt pulley drive reductor,
Sucker rod is driven, it is achieved oil pumping, its advantage is: when sucker rod overloading, and belt creep, to motor and deceleration through quadric chain
Machine plays a protective role.Its shortcoming is: transmission efficiency is low, and energy consumption is big, and belt deterioration is big, and maintenance is frequent.Permanent magnet direct driving motor
Beam pumping unit, eliminates belt transmission and reductor, and efficiency is high, easy to maintenance, but the torque of direct driving motor is little, volume
Greatly, manufacturing cost is high, and cost performance is low.
Summary of the invention
For problems of the prior art, the present invention provides a kind of gravity-driven oil pumper, has efficiency height, energy
Consume low, simple in construction and the advantage such as easy to operate.
For achieving the above object, the present invention is by the following technical solutions:
A kind of gravity-driven oil pumper, described oil pumper includes walking beam, hinge, pouring weight, Electric Traction mechanism, support and oil pumping
Bar,
Described hinge is arranged on the upper end of support, described walking beam by hinge rack-mount, the front end of described walking beam with
Sucker rod connects, and is provided with guide rail and sensor on walking beam, and described walking beam swings up and down in vertical direction with hinge for fulcrum,
Described pouring weight is made tandem by Electric Traction mechanism on guide rail and is moved, and when pouring weight is moved rearwards by, pouring weight drives walking beam
Making to swing clockwise, it is achieved Pumping action, when pouring weight moves forward, walking beam is made counterclockwise to swing, sucker rod to
Lower motion.
Described Electric Traction mechanism changes the arm of force size when dragging pouring weight front-rear reciprocation movement, thus is produced from center-of-gravity regulating position
Raw moment of torsion.
Compared with prior art, the invention have the benefit that
The present invention drives walking beam to make clockwise by pouring weight and swings, it is achieved Pumping action, when being moved forward by pouring weight, and trip
Beam is made counterclockwise to swing, and sucker rod moves downward；The oil pumper of the present invention is two bar pumping units, without belt pulley and deceleration
Machine, has efficiency high, the advantages such as energy consumption is low, and simple in construction is easy to operate, and cost is low.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
As it is shown in figure 1, the present embodiment gravity-driven oil pumper, described oil pumper includes walking beam 1, hinge 2, pouring weight 3, electricity
Power tractor 4, support 5 and sucker rod 6, described hinge 2 is arranged on the upper end of support 5, and described walking beam 1 is pacified by hinge 2
Being contained on support 5, the front end of described walking beam 1 is connected with sucker rod 6, is provided with guide rail 8 and sensor 9, described walking beam on walking beam 1
1 swings up and down in vertical direction with hinge 2 for fulcrum, before and after described pouring weight 3 is made by Electric Traction mechanism 4 on guide rail 8
Linear motion, when pouring weight 3 is moved rearwards by, pouring weight 3 drives walking beam 1 to make clockwise and swings, it is achieved Pumping action, works as pouring weight
3 when moving forward, and walking beam 1 is made counterclockwise to swing, and sucker rod 6 moves downward.
As preferably, during the present embodiment Electric Traction mechanism's dragging pouring weight front-rear reciprocation movement, change arm of force size, thus
The moment of torsion that center-of-gravity regulating position produces.
Although the present invention has been made specific descriptions by above-described embodiment, but comes for those of ordinary skill in the art
Say, it is understood that can modify based on present disclosure within without departing from the spirit and scope of the present invention
Or improve, these amendments and improvement are all within the spirit and scope of the present invention.
