The lower ends of the supports are fixedly connected to a base, and the upper ends of the supports are provided with bearing supports and used for supporting a transmission shaft; the wobble wheel and the chain gear are coaxially arranged on the transmission shaft; one end of the main oil cylinder and one end of the return oil cylinder are hinged with a support seat; the support seat is fixed on the supports; the connecting rod of the main oil cylinder and the connecting rod of the return oil cylinder are connected with two ends of the chain rack matched with the chain gear respectively; a plurality of grooves are formed on the outer circumference of the wobble wheel; one end of each steel wire rope is fixed in the corresponding groove of the wobble wheel, and the included angle between the two fixation points is 180 degrees; and the other ends of the steel wire ropes are connected with the balancing weight and the oil-well pump respectively. The hydraulic pumping unit of the utility model adopts a novel permanent magnet motor, so that the electric power is saved, the power network is protected, and the power consumption can be reduced by more than 40 percent. Therefore, the hydraulic pumping unit has the advantages of simple structure, flexible transmission and small occupied area, and operates steadily, can greatly reduce noise pollution and be applied to the operations of oil wells with various depths, and can also adapt to the wells in oil fields, which have low yields in the In addition, the service lives of the machine parts are comparatively longer.
Description
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
