Description
Technical field
The present invention relates to oil exploitation and produce the technical field of equipment, particularly relate to a kind of stroke-frequency changing device of beam-pumping unit.
Background technology
At mid-late oilfield development, the oil well that the production fluid amount is low and heavy oil wells power consumption are large, expensive poor benefit.Reason is down-hole oil reservoir feed flow deficiency and causes pump efficiency to reduce, even the free phenomenon of taking out.In order to solve the dynamically middle under-supply contradiction of fluid of oil well production, generally can adopt the reduction beam-pumping unit jig frequency, but in fact the change of stroke at first is subject to the type restriction, and adjustable extent is less, mainly is to satisfy each oil well jig frequency coupling requirement by reducing the oil pumping jig frequency.
The equipment great majority that change jig frequency in the prior art are to adjust by reductor, because the reaction force to transmission system in the beam pumping unit running is larger, easily the gear of reductor inside produced larger impact, the wearing and tearing of gear are than very fast, reductor damage also just than comparatively fast, because the cost of reductor is higher, has caused the raising of the cost of winning of oil, inefficiency.
Summary of the invention
The objective of the invention is provides a kind of stroke-frequency changing device of beam-pumping unit in order to address the above problem.
Technical scheme of the present invention is: a kind of stroke-frequency changing device of beam-pumping unit, contain motor, the movable installing mechanism of motor, double tower wheel output mechanism, the movable installing mechanism of described motor comprises the square floor that is connected with motor, the square box frame plate that base plate top press-fits, the middle part of frame plate is provided with square orifice, the length and width of this square orifice are less than the length and width of square floor, described square floor frame plate four edges are provided with flanging, jackscrew is installed on the flanging, jackscrew passes flanging and installs and contact with the edge of square floor, described motor is installed in the middle part of square floor, and described motor shaft is connected with the transmission mechanism of oil pumper by the cone pulley output mechanism.
Described oil pumper transmission mechanism is energy-saving mechanism, comprise casing, power shaft, output shaft, freewheel clutch, described power shaft and output shaft all are installed in the casing by two spring bearings, described freewheel clutch is connected on the inner end of power shaft and output shaft, described power shaft outer end is provided with cone pulley, is connected by belt with cone pulley on the motor shaft.
Described casing inside is provided with oil sump, and the inner end of described power shaft and output shaft all is positioned at oil sump, and described freewheel clutch also is in this oil sump.
The installation sole of described motor is connected to the middle part of square floor by set bolt; The width that overlaps the zone of square floor and square box frame plate is greater than the length of cone pulley.
Beneficial effect of the present invention
The change stroke-frequency device of this invention is by adopting the cone pulley transmission, movable installing mechanism in conjunction with motor, can adjust flexibly the jig frequency of oil pumper, adjustable range is larger, again in conjunction with the energy-saving type transmission mechanism, can avoid the reaction force of oil pumper that transmission mechanism is impacted in addition, guarantee the application life of motor and transmission mechanism, can significantly lower the cost of winning of mid-late oilfield development, reduce the exploitation difficulty.
This invention is adjusted in the jig frequency process, does not need to change belt, only needs just can finish the process that jig frequency is adjusted by adjusting jackscrew, and labour intensity is low, high efficiency.
Become stroke-frequency device with original gearbox and compare, do not have mechanical wear, substantially got rid of the possibility that breaks down, only need reach rear replacing belt just application life until belt.
