Abstract
The utility model discloses an impulse-changing number pumping unit, is composed of a motor, a gear box, a crank shaft, a connection rod, a walking beam and a horsehead. The speed shifting mechanism is arranged between the motor and the crank shaft connection rod. The speed shifting mechanism is provided with an output shaft and input shaft. An output gear group and an input gear group are respectively arranged on the output shaft and input shaft. Engagement pairs with different transmission ratio are formed by the output gear group and input gear group sliding on the shaft. A coupling is arranged on one end of the output shaft, is connected with the crank shaft connection rod. A transmission wheel is arranged on the input shaft to form a transmission pair with the motor. Thus the decelerated motion from the motor to the crank shaft connection rod is completed and the impulse-changing number of the pumping unit can be controlled. The gear speed shifting mechanism is adopted. By adjusting the engagement relation between the output gear box and input gear, the impulse-changing number can be set, thus the adjusting range of the impulse number is wider, and according to the oil amount of the oil field, the impulse number can reach best matching. The device is provided with simple structure, convenient installation and using, can be extensively used in the speed regulating device of different pumping unit.
Description
Technical field:
The utility model discloses a kind of novel change strokes per minute oil pumper, belongs to the oil field oil production equipment
Technical field.
Background technology:
At present, the oil pumper that use in the oil field comprises beam type and no beam type structure, and its strokes per minute that drives oil well pump all is changeless, therefore, for the exploitation in low-abundance oil field, the pumping power surplus of oil pumper will be caused, efficient reduces, and strengthens the wearing and tearing of plant equipment.Usually reduce the strokes per minute of oil pumper by the method that changes the motor pulley diameter, but owing to be subjected to former design reducer gearratio and the limitation of selecting the motor ratio of revolutions for use, to drop to strokes per minute below 4 times, exist motor pulley and become too small, cause belt contact very little, greatly reduce problems such as transmission efficiency, and shortened belt application life, influenced the operate as normal of oil pumper.
Summary of the invention:
The utility model provides a kind of change strokes per minute oil pumper, and it is constant to have overcome existing oil pumper strokes per minute, causes the problem that operating efficiency reduces, plant equipment is wasted.
Technical solution of the present utility model is as follows: by motor, gear, reduction box, bent axle, connecting rod, walking beam and horse head constitute, wherein, the gear device is at motor and reduction box, between the crankshaft-link rod, in gear, be provided with output shaft, power shaft, on it respectively device the output gear wheels are arranged, the input gear train, by on axle separately, slide constituting the Meshing Pair of different drive ratios, one end of output shaft also is provided with shaft coupling and is connected with crank connecting link, power shaft is provided with drive and motor constitutes transmission, finish motor to reduction box, the retarded motion of crank connecting link, the change strokes per minute of control oil pumper.
Belt pulley by configuration different-diameter on the output shaft shaft coupling can also obtain more strokes per minute.
Good effect of the present utility model is: adopt gear shift, by adjusting the meshing relation of output gear wheels, input gear train, set the change strokes per minute of oil pumper, make strokes per minute amplitude modulation wideer, the rich oil mass according to the oil field reaches optimum Match.This apparatus structure is simple, and is easy to install, can be widely used in the arrangements for speed regulation of various oil pumpers.
Description of drawings:
Fig. 1 is the utility model structure principle chart.
Fig. 2 is the utility model gear structure principle chart.
The specific embodiment:
According to shown in Figure 1, motor 1 is located on the pedestal of oil pumper, its output is connected with the power shaft 8 of gear 2, reduction box 3 constitutes transmission by the output shaft 11 of belt pulley and gear 2, crank 4 is connected between connecting rod 5 and the gearbox 3, connecting rod 5 and walking beam 6 hinged drive horse head 7 work.With reference to Fig. 2, be provided with output shaft 11, power shaft 8 in the gear 2 side by side, on it respectively device have output gear wheels 10, the input gear train 9, and can on axle separately, slide constitute the Meshing Pair of different drive ratios, adopt 3 groups of change-speed gearings in the present embodiment, one end of output shaft 11 also is provided with shaft coupling 12 and is connected by the input of belt with reduction box 3, and power shaft 8 is provided with drive and motor 1 constitutes transmission, finishes the power transmission process.
