Abstract
A low pumping speed pumping unit mainly solves the high pumping speed of the walking-beam pumping unit of the prior art, which is characterized in that a third grade driving shaft (3) is fixed between a output shaft (4) and a second grade driving shaft (2), wherein the two ends of the third grade driving shaft (3) are connected with left-and right gear wheels (7) which mesh pinion wheels (9) of the second grade driving shaft (2), and the third grade driving shaft (3) are connected with a pinion wheel (6) which meshes a gear wheel (5) of the output shaft (4). The low pumping speed pumping unit is characterized by being low in pumping speed.
Description
Technical field:
The utility model relates to used lifting device in the oil recovery field, oil field, especially low jig frequency oil pumper.
Background technology:
Along with the most of oil field of China has entered the exploitation middle and later periods, stripper well exploitation quantity constantly increases, in the peripheral oil recovery factory of grand celebration, have at present quite a few stripper well production fluid amount the 2-4 ton the sky, following pump is that diameter is 3 series of 32,38 and 44, by theoretical design stroke 2.5m design, minimum jig frequency should reach per minute 2 times.And present common beam pumping unit amount low jig frequency is a per minute more than 4 times, because of stripper well feed flow deficiency, causes sky generally to occur and take out phenomenon.Not only power consumption is big, and oil pipe, sucker rod, oil well pump serious wear, is unfavorable for applying.
The utility model content:
In order to solve the existing high problem of beam pumping unit jig frequency, the utility model provides a kind of low jig frequency oil pumper, and this low jig frequency oil pumper has the low characteristics of jig frequency.
The technical solution of the utility model is: this low jig frequency oil pumper comprises one-level driving shaft, secondary driving shaft and output shaft in the reducer, revolving gear about one-level driving shaft gear and secondary driving shaft is harmonious, be fixed with three grades of driving shafts between output shaft and secondary driving shaft, three grades of both ends of main drive shaft are connected with about three grades that are meshed with pinion on the secondary driving shaft and revolve gear wheel, be connected with on three grades of driving shafts with output shaft on the gear wheel pinion in mesh.
Gear wheel and pinion on three grades of driving shafts in the such scheme can be helical teeth.
The utlity model has following beneficial effect: this low jig frequency oil pumper is owing to take such scheme, use the jig frequency that triple reduction gear has reduced oil pumper, can guarantee that not only output does not subtract, and oil pipe, sucker rod, oil well pump wearing and tearing number of times have been reduced, increase the service life, oil pumper necessary electromotor power can reduce by 2～3 specifications in addition, and energy-saving effect is obvious.Make a large amount of stripper wells obtain rationally effectively exploitation.Help applying.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
1-one-level driving shaft among the figure, 2-secondary driving shaft, three grades of driving shafts of 3-, 4-output shaft, gear wheel on the 5-output shaft, pinion on three grades of driving shafts of 6-, gear wheel on three grades of driving shafts of 7-, revolve gear about on the 8-secondary driving shaft, pinion on the 9-secondary driving shaft, 10-reducer.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, this low jig frequency oil pumper comprises one-level driving shaft 1, secondary driving shaft 2 and output shaft 4 in the reducer 10, revolving gear 8 about one-level driving shaft 1 gear and secondary driving shaft 2 is harmonious, 2 on output shaft 4 and secondary driving shaft are fixed with three grades of driving shafts 3, three grades of driving shaft 3 two ends are connected with about three grades of being meshed with little angular gear 9 on the secondary driving shaft 2 and revolve and be connected with the little angular gear 6 that is meshed with big angular gear 5 on the output shaft 4 on 7, three grades of driving shafts 3 of big angular gear.Rotate by the gear that belt drives on the one-level driving shaft 1 by pumping-unit motor, be harmonious by revolving gear 8 about gear and secondary driving shaft 2, making on the secondary driving shaft 2 little angular gear 9 drive about three grades revolves big angular gear 7 and rotates, revolve big angular gear 7 about three grades and drive big angular gear 5 rotations on the output shaft 4, output shaft 4 drive cranks, connecting rod, walking beam are up and down reciprocatingly swung, and finally reach the purpose of lifting well liquid.Owing to adopted triple reduction gear, reduced the jig frequency of oil pumper, can guarantee that so not only output does not subtract, and because of the jig frequency reduction, so reduced oil pipe, sucker rod, oil well pump wearing and tearing number of times, prolong oil pipe, sucker rod, oil well pump application life, reduce by 2～3 specifications because of oil pumper necessary electromotor power in addition, energy-saving effect is obvious, thereby reduces cost for oil production greatly.Make a large amount of stripper wells obtain rationally effectively exploitation.Help applying.
Claims (2)
1, a kind of low jig frequency oil pumper, comprise one-level driving shaft (1), secondary driving shaft (2) and output shaft (4) are arranged in the reducer (10), revolving gear (8) about one-level driving shaft (1) gear and secondary driving shaft (2) is harmonious, it is characterized in that: be fixed with three grades of driving shafts (3) between output shaft (4) and secondary driving shaft (2), three grades of driving shafts (3) two ends are connected with goes up about three grades that pinion (9) is meshed with secondary driving shaft (2) and revolves gear wheel (7), is connected with on three grades of driving shafts (3) with output shaft (4) and goes up gear wheel (5) pinion in mesh (6).
2, low jig frequency oil pumper according to claim 1 is characterized in that: gear wheel (7) and pinion (6) on three grades of driving shafts (3) can be helical teeth.
