Abstract
A mobile counterweight type pumping unit comprises a counterweight type balancing mechanism, a triangular support, a crank and connecting rod mechanism and frame. The counterweight type balancing mechanism comprises a walking beam, two slideways, a reciprocating screw rod, two counterweight blocks, a variable frequency motor and a horsehead. The variable frequency motor is fixed on the right of the upper end face of the walking beam and is connected to the right end of the reciprocating screw rod. The left end of the reciprocating screw rod is supported on the left of the upper end face of the walking beam through a screw rod bearing. The slideways are fixed on two sides of the walking beam. A nut is fitted on the reciprocating screw rod. Two identical counterweights are fixed onto the nut and are slidably fitted with the slideways respectively. A balancing block is fixed at the right end of the walking beam. The upper end of the triangular support is connected with the walking beam through a triangular support shaft. The upper end of a connecting rod is connected with the walking beam through an upper shaft. The lower end of a crank is connected with a shaft seat through a crankshaft. The lower end of the triangular support and the shaft seat are fixed onto the frame respectively. By replacing an original balancing block and a reducer with the counterweights and adding the balancing block onto the walking beam, the mobile counterweight type pumping unit is simple in structure and energy-saving.
Description
Technical field
The invention belongs to the oil pumper field, particularly a kind of self-balanced upper rotary formula oil pumper of pumping realized with self-balanced upper rotary.
Background technology
At present, the oil field crank-balanced pumping unit that is widely used, in actual motion, upstroke institute work is weight and overcome frictions such as lifting arm, pump, fluid column, and the down stroke work has only the weight of bar, pump etc.This just explains that oil pumper is in actual motion; The required merit of upper and lower stroke is different, and this has just formed the waste of portion of energy, wherein for the weight of bar, pump etc.; This part weight can be employed in the mode that installs balance weight on the walking beam additional and balance, and realizes energy-conservation effect.Simultaneously; Former crank-balanced pumping unit in the course of the work; A big chunk acting of motor is in the balance weight that the drives crank-balanced pumping unit mechanical resistance inner with overcoming reduction box; Employing self-balanced upper rotary formula oil pumper can remove the balance weight and the reduction box of former crank-balanced pumping unit, more can be energy-conservation greatly.
So; Realize that with self-balanced upper rotary the self-balanced upper rotary formula oil pumper of pumping is that realistic meaning is arranged very much; Adopt self-balanced upper rotary formula oil pumper can remove the balance weight and the reduction box of former crank-balanced pumping unit; And the weight of the bar of the crank-balanced pumping unit that will adopt usually at present, pump etc. is employed in the mode that installs balance weight on the walking beam additional and balances, and realizes energy-conservation effect.
Summary of the invention
The purpose of this invention is to provide self-balanced upper rotary formula oil pumper, this oil pumper is to the shortcoming of the energy waste of existing crank-balanced pumping unit existence, removes its balance weight and reduction box, uses balancing weight to realize oil pumping, reaches purpose of energy saving.
The technical scheme that adopts is:
Self-balanced upper rotary formula oil pumper comprises balancing weight formula balanced controls, tripod, crank-link mechanism and frame.
Its technical essential is:
Balancing weight formula balanced controls comprise walking beam, two identical slideways, back and forth leading screw, two identical balancing weights, variable-frequency motor and horse heads.
Variable-frequency motor is fixed on the right side, upper surface of walking beam, and variable-frequency motor connects through the right-hand member of shaft coupling with reciprocal leading screw, and back and forth the left end of leading screw passes through the leading screw seat supports in left side, walking beam upper surface.Both sides at walking beam
-1-
Be fixed with slideway respectively.
Back and forth be equiped with screw on the leading screw, be fixed with two identical balancing weights on the screw, described two balancing weights lay respectively at the both sides of walking beam, and are slidingly matched with said two slideways respectively.
Right-hand member at described walking beam is fixed with balance weight.
The left end and the horse head of walking beam connect firmly.
The upper end of tripod connects with walking beam through the tripod axle, and the lower end of tripod is fixed on the frame.
Crank-link mechanism comprises connecting rod, crank and axle bed.
Small end connects with walking beam through axle on the connecting rod, connects through the connecting rod lower shaft between connecting rod lower end and the crank upper end.
The crank lower end connects with axle bed through crank axle, and axle bed is fixed on the frame.
Its course of work is:
Balance weight is arranged on the walking beam end, in order to weight such as the pump that balances former crank-balanced pumping unit, bars.
Variable-frequency motor rotates, and drives reciprocal leading screw and rotates, and screw produces and moves; And then drive the slip of balancing weight property along the line slideway, promptly balancing weight makes walking beam do seesaw-type and moves up and down in walking beam tripod fulcrum two side shiftings; Accomplish the up-down stroke action of oil pumper, realize oil pumping.
Crank-link mechanism plays centralizing function.
Energy-conservation and operating principle:
This kind oil pumper when work, move and realize oil pumping through only driving balancing weight on the walking beam, cancelled original balance weight, reduction box, can realize energy-conservation effect.
Accompanying drawing 2 is the fundamental diagram of existing self-balanced upper rotary formula oil pumper, and Wb is a balance weight.
Calculate through energy below, set forth self-balanced upper rotary formula oil pump energy-saving principle this oil pumper:
Because: Eu=(Wr+Wl+F1) * S (formula 1)
Ed=(Wr+F2) * S (formula 2)
Annotate: Eu---the energy that upstroke is required.
Ed---the energy that down stroke is required.
Wr---bar, pump weight.
Fluid column weight in Wl---the oil pipe.
F1---upstroke frictional force, suction etc.
F2---down stroke frictional force, buoyancy etc.
S---oil well pump stroke.
Same through balancing weight formula oil pumper of the present invention, balance weight, variable-frequency motor acting can draw:
-2-
Eu=
S*Wb+Wm1
Ed=?
S*Wb+Wm2
In the formula: Wm1, Wm2 are respectively that variable-frequency motor is in up-down stroke institute work.
Can know that by formula 1 and formula 2 energy of Eu, Ed is unequal, like this foundation:
Eu=(Wr+Wl+F1)*S Ed=(?Wr+F2)?*S
Promptly draw:
(Wr+Wl+F1)*S=
S*Wb+Wm1
(?Wr+F2)?*S?=
S*Wb+Wm2
Wr*S=
S*Wb (balance weight that installs additional is identical with pump rod weight, i.e. Wr=Wb)
Abbreviation both drew:
（Wl+F1）=?Wm1
F2=?Wm2
Variable-frequency motor institute work is: Wm1=(Wl+F1), Wm2=F2 has significantly reduced variable-frequency motor institute work.
Its advantage is:
The present invention adopts balancing weight to remove former balance weight and reduction box, and the weight for bar, pump etc. is employed in the mode that installs balance weight on the walking beam additional to balance, and simple in structure, energy conservation reaches energy-conservation purpose.
