Abstract
The invention relates to a pumping unit convenient for adjusting balance, which belongs to the field of petroleum extraction machines. The pumping unit comprises a main motor, a speed changing box, a crank, a connecting rod, a stand, a walking beam, a fixed balance block and an adjusting mechanism, wherein the rear part of the walking beam is provided with the adjusting mechanism, and the adjusting mechanism comprises a movable balance block, a lead screw, an adjusting motor, a speed reducer and a control box. The movable balance block is connected with the lead screw and straightly reciprocates following the rotation of the lead screw. The lead screw is connected with the adjusting motor through the speed reducer, and an adjusting motor power line is led into the control box along the walking beam and the stand. The invention realizes that the movable balance block moves back and forth on the walking beam through controlling the positive rotation and the inverse rotation of the adjusting motor on the ground, thereby ensuring that the pumping unit is convenient for adjusting balance without stopping production and closing down.
Description
Technical field
The present invention relates to a kind of oil pumper of being convenient to adjust balance, belong to the oil exploitation mechanical field.
Background technology
In the course of work, because the variation of hole condition and pump condition, original balance can be damaged oil pumper, thereby need carry out the balance adjustment again at the scene.But existing oil pumper carries out balance adjustment difficulty height, workload is big, and must shut down, stop production.
Summary of the invention
In order to overcome the above-mentioned deficiency of existing oil pumper, the invention provides a kind of oil pumper of being convenient to adjust balance, not only the balance adjustment is very simple for it, and needn't stop production, shut down.
The present invention seeks to be achieved through the following technical solutions: the oil pumper of being convenient to adjust balance is made up of main motor, gearbox, crank, connecting rod, frame, walking beam, stable equilibrium piece, governor motion, it is characterized in that: have a governor motion at the rear portion of walking beam, this governor motion is made up of mobile equilibrium piece, leading screw, adjusting motor, reductor, control box.
Described governor motion is characterized in that mobile equilibrium piece and leading screw link, and the mobile equilibrium piece is along with linear reciprocating motion is done in the rotation of leading screw.
Described governor motion is characterized in that leading screw links by reductor and adjusting motor.
Described adjusting motor is characterized in that regulating motor power-supply wire and is incorporated in the control box along walking beam, frame.
The invention has the beneficial effects as follows: realize moving before and after the mobile equilibrium piece is on walking beam by the forward and backward of control and regulation motor on ground, thereby it is very easy and need not stop production, shut down to make oil pumper adjust balance.
Description of drawings
Accompanying drawing is a complete machine structure schematic diagram of the present invention.
Among the figure: 1. motor; 2. gearbox; 3. crank; 4. connecting rod; 5. stable equilibrium piece; 6. leading screw; 7. mobile equilibrium piece; 8. reductor; 9. adjusting motor; 10. adjusting motor power-supply wire; 11. walking beam; 12. horse head; 13. frame; 14. control box; 15. base.
The specific embodiment
The present invention will be further described below in conjunction with specific embodiment:
Accompanying drawing can be used as the structural representation of the specific embodiment of the invention.Set up a stable equilibrium piece (5) and a mobile equilibrium piece (7) at the rear portion of walking beam (11).The gross weight of stable equilibrium piece (5) and mobile equilibrium piece (7) can be estimated by half sum of fluid column weight on weight that approximates oil pumper work sucker rod that time joins and the oil pump plunger piston.Stable equilibrium piece (5) is about 3: 1 with the ratio of the weight of mobile equilibrium piece (7).Stable equilibrium piece (5) is preferably made the multi-disc combining structure, is fixed by bolts on the walking beam (11), does the necessary adjustment that increases, subtracts when changing significantly so that the hole condition of oil pumper work or pump condition have.Mobile equilibrium piece (7) moving forward and backward by leading screw (6) on walking beam (11) drives, and leading screw (6) links by reductor (8) and adjusting motor (9).Regulate motor power-supply wire (10) and guide in the control box (14) of frame (13) bottom under along walking beam (11) to rotating shaft place, regulate motor (9) in Ground Control with the handled easily person.
Can be at the governor motion at walking beam (11) rear portion on the top of walking beam (11), also can be in the bottom of walking beam (11).Governor motion can prevent to drench with rain in the bottom of walking beam (11).Governor motion in the accompanying drawing is on the top of walking beam (11).
The on-the-spot balance of adjusting of oil pumper is carried out as follows: snap in a clamp on amperemeter on the power line of pumping-unit motor (1), with the current amplitude of monitoring oil pumper in upper and lower stroke.If the amplitude of electric current in upper and lower stroke is unequal, then operate control box (14), make and regulate the motor forward or reverse, drive mobile equilibrium piece (7) through leading screw (6) and move forward or backward, till upper and lower stroke current amplitude equates.Can the follow conventional lines single-spar construction of oil pumper of walking beam of the present invention (11), the also beam frame structure that can adopt accompanying drawing to provide, the advantage of beam frame structure is to save rolled steel dosage.Connecting rod of the present invention (4) suffered tensile force in the oil pumper upstroke, suffered compressive force in down stroke will fully satisfy the requirement of compressive strength in the design of its intensity.Crank of the present invention (3) is not because of needing additional bob-weight thereon, as long as its length can satisfy the needs of oil pumper length of stroke.Other parts that the present invention relates to such as motor (1), gearbox (2), horse head (12) etc. are identical with existing oil pumper, can implement with reference to prior art.
Claims (4)
