Description

Hydraulic pumping unit
Technical field
The utility model relates to a kind of oil recovery machiner, is specifically related to a kind of hydraulic pumping unit.
Background technology
At present, mostly the oil pumper that the oil recovery industry is used is the machine driving chain type, be by the driven by motor reduction box after three grades or level Four are slowed down, spur walking beam with crank-link mechanism, walking beam pulling wire rope makes its work done, because oil well is all deep, more than one meter, moment of torsion is bigger when causing traditional oil pumper to start, needed moment of torsion approximately is more than 1.5 times of operate as normal, life-span to the stabilization of power grids and motor can both produce certain negatively influencing, and load lightens when normal oil pumping, and torque ratio is less, motor is in substantially and freely transfers state when transferring, increase reactive loss, make system effectiveness low, power consumption is serious, motor average load rate is low, low load with strong power, the mechanical driving part energy consumption is bigger, and energy waste is serious.Well ground in the geological condition complexity, thick as oil, contain sand, wax deposition is more, the comparison difficulty of smoking, when particularly the intermediary and later stages well location of oil well hangs down shortage of oil, need to regulate jig frequency, traditional oil pumper often needs the power distribution cabinet of replacing belt pulley or reduction box etc., more loaded down with trivial details, dangerous big, workload is big, and expense increases.
Summary of the invention
The purpose of this utility model is to provide a kind of hydraulic pumping unit, and this oil pumper can be to jig frequency, the stepless level and smooth adjustment of stroke.Hydraulic-driven, the flexible transmission of chain, stable working, easy to adjust, mechanical efficiency height.
For achieving the above object, the utility model hydraulic pumping unit comprises hydraulic power station, master cylinder, the return oil cylinder, support, wobble wheel, sprocket, the chain tooth bar, wire rope, oil well pump and balancing weight, hydraulic power station is connected with master cylinder and return oil cylinder, two supports are arranged on the support, two stands is by the bearing block support power transmission shaft, coaxial wobble wheel and the drive chain gear of being provided with, the chain tooth bar is set on the sprocket, master cylinder and return oil cylinder one end and supporting base are hinged, supporting base is fixed on the support, the connecting-rod head of two oil cylinders is affixed with the two ends of chain tooth bar respectively, wobble wheel is provided with a plurality of grooves along excircle, two wire rope one ends of work done and counterweight are separately fixed in the groove of wobble wheel, and the angle of two fixed points is 180 °, and the other end of two wire rope is connected with oil well pump with balancing weight behind the wobble wheel groove respectively.
Described support also is provided with diagonal member for stablizing consideration, also is provided with drag link between diagonal member and support.Because this oil pumper hydraulic power station adopts the novel permanent magnetic motor after the alternating current of frequency conversion drives oil pump generation hydraulic oil; restart hydraulic control device; so electric motor starting is steady relatively; motor does not have tangible starting current peak value; conservation of power, protection electrical network; compare with the mechanical oil pumper of same model, can make main capacity motor reduce 1/3, power consumption can reduce 40% more than.Adopt sprocket, the transmission of chain tooth bar can make that this oil pumper has simple in structure, flexible transmission, parts comparative lifetime is long, floor space is little, operate steadily, can significantly reduce noise pollution, change wobble wheel size and bracket height, can adapt to the oil well operation of the various degree of depth.
Description of drawings
Fig. 1 is the schematic diagram of the utility model hydraulic pumping unit front view
The specific embodiment
The utility model hydraulic pumping unit comprises power station 11 as shown in the figure, master cylinder 5, return oil cylinder 8, support 12, wobble wheel 2, sprocket 1, chain tooth bar 3, wire rope 4, balancing weight 6, oil well pump 10, described hydraulic power station is made up of AC permanent-magnet motor and high-pressure oil pump, hydraulic power station is connected with master cylinder and return oil cylinder 8 through high-pressure oil pipe, two oil cylinder lower ends are hinged on the supporting base 9, supporting base is fixed on the support, support 12 bottoms are fixed on the base 7, the top is provided with bearing support and supporting drive shaft, this coaxial wobble wheel 2 and sprocket 1 of being provided with, chain tooth bar 3 is arranged on the sprocket, chain tooth bar two ends are connected with the connecting rod of master cylinder and return oil cylinder respectively, wobble wheel 2 is provided with a plurality of grooves along excircle, two wire rope one ends are separately fixed in the wobble wheel groove, the angle of two fixed points is 180 °, and the other end of wire rope is connected with oil well pump with balancing weight 6 respectively.
For strengthening the stability of support, a diagonal member 7 can also be set between base and support, and can between diagonal member and support, drag link be set.
Also can adjust the work done angle of master cylinder and return oil cylinder, make its conversion between 20 °-120 ° according to the difference of geological conditions.
The utility model is provided with left and right two supports, and one of them can rotate around another support for can adjust setting, makes things convenient for well maintenance.
During work, when hydraulic power station output hydraulic power oil enters master cylinder and return oil cylinder, under the effect of hydraulic control system, master cylinder and return oil cylinder are done opposite running, thereby it is reciprocating to drive the sprocket bar, and drive the sprocket crop rotation and back and forth rotate, the swing crop rotation that drives coaxial setting simultaneously is less than 360 ° of reciprocally swingings, and the wobble wheel external diameter is about 2500 millimeter.Relative fixed two wire rope in the groove of wobble wheel excircle, and the balancing weight and the oil well pump of the other end are reciprocating, finish oil pumping.The control system of hydraulic power station can freely, infinitely change the pendulum angle of wobble wheel, the effective travel length of change oil pumper and the jig frequency in the unit interval, rotating speed stepless adjustment between 100-1500 rev/min can be realized, stepless adjustment in stroke 1-7 rice, 0.1-16 time/minute scope of jig frequency can be realized.
