Abstract
A kind of beam pumping unit of two-polar counterweight compensation belongs to the field of oil exploration machinery. The model is composed of a motor, a gearbox, a crank, an original eccentric counterweight, a rotating arm, an additional eccentric counterweight, a connecting rod, a beam, a rack, etc. The characteristics of the model are: in the gearbox is added one-level additional gears; the gears are directly meshed with the output gears of the gearbox or indirectly meshed through the additional dielectric gears; the axis extends out the two ends of the gearbox and fixes an additional eccentric counterweight respectively through the rotating arms. The ratio of the rotate speeds of the additional gears and the output gears of the gearbox is 2 to 1. When the original eccentric counterweight rotates to the right upper part, the additional eccentric counterweight rotates to the horizontal level or above the horizontal level of the rising semi-cycle. Based on the compensation of the original eccentric counterweight, the additional eccentric counterweight is added in the utility model, forming the two-polar counterweight compensation to further compensate the load of the motor; thus the rating power of the allocated motor is significantly reduced, which makes the motor efficiency and the power factor greatly improved.
Description
Technical field
The utility model relates to a kind of two-stage counterweight offset-type beam pumping unit, belongs to the oil exploitation mechanical field.
Background technology
Used beam pumping unit all has only the compensation of one-level counterweight in the oil exploitation at present, promptly respectively adds an eccentrically mounted weight on the crank at output shaft of gear-box two ends, in order to the load characteristic of small electromotor.This beam pumping unit that has only one-level eccentrically mounted weight compensation, even under optimal duty, the power output of motor in each oil pumping cycle all is pulsation deformationization in time, the amplitude of pulsation is much larger than its average.On-the-spot in order to guarantee that oil pumper can normal starting and work, all select high-power motor for use, the rated power of institute's adapted motor must be more than or equal to the amplitude of pulsating power, cause the average load rate of motor very low thus, average efficiency during machine operation and average power factor are all lower, thereby cause bigger motor resource and waste of power resources.
Summary of the invention
Big and operating efficiency, deficiency that power factor is lower for the rated power that overcomes existing beam pumping unit adapted motor, the utility model provides a kind of two-stage counterweight offset-type beam pumping unit, this oil pumper not only rated power of adapted motor is little, and the operating efficiency of motor and power factor are all very high.
The purpose of this utility model is achieved through the following technical solutions: a kind of two-stage counterweight offset-type beam pumping unit is made up of motor, gearbox, crank, original eccentrically mounted weight, spiral arm, additional eccentrically mounted weight, connecting rod, walking beam, frame etc.It is characterized in that: set up the one-level additional gear in gearbox, this gear and the direct geared of gearbox output stage are meshed or are meshed indirectly by additional idle wheel, and its shaft extension goes out the outer two ends of gearbox, and each fixes an additional eccentrically mounted weight through spiral arm.
Described additional gear is characterized in that: the rotating ratio of additional gear and gearbox output stage gear is 2: 1.
Described additional eccentrically mounted weight is characterized in that: in the time of directly over original eccentrically mounted weight rotates to, additional eccentrically mounted weight dextrorotation is to the level or the level position on the upper side of the half cycle that rises.
The utility model is because on the basis of original eccentrically mounted weight compensation, set up additional eccentrically mounted weight again, form the two-stage eccentrically mounted weight thus the load characteristic of motor is done further compensation, reduced the amplitude of motor power output effectively, therefore under identical condition, can significantly reduce the rated power of oil pumper adapted motor, improve its average load rate, and then motor working efficiency and power factor are greatly improved.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further.
Fig. 1 can be used as the complete machine structure schematic diagram of the utility model specific embodiment, and the additional eccentrically mounted weight that Fig. 2 can be used as the utility model specific embodiment is provided with structural representation partly.Specific implementation method is: set up an additional idle wheel (10) and an additional gear (11) in gearbox (2), additional gear (11) is meshing with gearbox output stage gear (9) by additional idle wheel (10).Additional gear (11) is 2: 1 with the rotating ratio of gearbox output stage gear (9).The purpose of setting up additional idle wheel (10) is the distance that strengthens between additional gear rotating shaft (12) and the gearbox output revolving shaft (8), to ensure spiral arm (15) enough revolution spaces is arranged.Whether reality sets up additional idle wheel, and the size of additional idle wheel diameter, and whether the scene of looking satisfies the revolution space of spiral arm (15) is determined.Additional gear rotating shaft (12) is stretched out outside the gearbox (2), and the two ends outside stretching out gearbox link by meshing dish (14) and spiral arm (15), and additional eccentrically mounted weight (16) is fixed on the spiral arm (15).Relative position relation between additional eccentrically mounted weight (16) and the original eccentrically mounted weight (4) can be adjusted and fix by the following method: fixed-site was motionless directly over original eccentrically mounted weight (4) was threaded to, unclamp locking nut (13), the direction of rotation of additional eccentrically mounted weight (16) is rotated the horizontal level of additional eccentrically mounted weight (16) to the half cycle that rises during according to the oil pumper actual motion, it is temporarily fixing to screw locking nut (13) then, fine tuning adds the angle that eccentrically mounted weight (16) upward deflects at horizontal level again when the oil pumper actual motion, till motor (1) output-power fluctuation minimum.Adjust and the fixing deflection angle that adds eccentrically mounted weight (16) for convenient, present embodiment has adopted fluted disc to connect form between rotating shaft (12) and spiral arm (15), promptly two planes can intermeshing disk, one dish is fixed in the rotating shaft (12), another dish is fixed on the spiral arm (15), unclamping the engagement of locking nut (13) two disk detachments can relatively rotate, and screws locking nut (13) two dishes and is in engagement.
Other parts that the utility model is related, as: motor (1), crank (3), original eccentrically mounted weight (4), connecting rod (5), walking beam (6), frame (7) etc., its structure and correlation are identical with existing beam pumping unit, can implement with reference to prior art.
