Abstract
The utility model discloses a hydraulic pumping unit, which comprises a hydraulic power station, oscillating oil cylinders, a left bracket, a right bracket, a frame, a wobble wheel, two work-doing wire ropes, and two counterweight wire ropes. The wobble wheel is coaxially arranged with a small gear, the small gear engages with the racks arranged on the oil cylinder plug of the oscillating oil cylinder, the two oscillating oil cylinders arranged on the left side and the right side can do work in a balanced way, and a motor is obviated. Two oscillating oil cylinders arranged on the upper side and the lower side can improve operating efficiency. One of the brackets can rotate around the other bracket, so as to facilitate oil well maintenance. The two work doing wire ropes and two counterweight wire ropes are arranged in a self-locking way to avoid power loss due to slippage. The hydraulic pumping unit has the advantages of simple structure, good durability, small occupied space, and low running noise; and is suitable for all-weather operating conditions. The hydraulic pumping unit can be operated in oil wells with various depths by changing the diameter of the wobble wheel and the height of the brackets.
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 complicated, 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 oil oil machine, and current of electric was steady relatively when this machine started, and mechanism's chain is few, and the transmission energy consumption is little, can stepless control jig frequency, and hydraulic drive is conveniently regulated the efficient height.
For achieving the above object, the utility model hydraulic pumping unit, comprise hydraulic power station, oscillating oil cylinder, support, support, wobble wheel, wire rope and balancing weight, hydraulic power station is connected with oscillating oil cylinder, a left side, right two supports are arranged on the support, pass through bearings one wobble wheel between the two stands, with the coaxial pinion that is provided with of wobble wheel, the oil cylinder that swings is arranged on the support, the oil cylinder plunger of oscillating oil cylinder is provided with tooth bar, be meshed with pinion, the wobble wheel excircle is provided with a plurality of grooves, and work done wire rope and counterweight wire rope are separately positioned in the groove, two wire rope one ends are separately fixed on the wobble wheel, the angle of two fixed points is 180 °, and the counterweight wire rope other end connects balancing weight, and the work done wire rope other end connects the oil pumping oil pump.
Described oscillating oil cylinder is provided with two, is set up in parallel up and down on support, is respectively equipped with tooth bar on the oil cylinder plunger of upper and lower oscillating oil cylinder, is meshed with pinion.Described one of them support is movably arranged on the support.
Because the utility model hydraulic pumping unit, motor directly drive hydraulic power station and produce high pressure, the swing of hydraulic pressure oscillating oil cylinder band wobble wheel, the work done of pulling wire rope.Motor can idle startup after, start oil well with hydraulic control valve, and adopt equilibrium principle, current of electric is steady relatively during startup, and motor and electrical network are not had injury.The utility model only need be adjusted the flow speed control valve of hydraulic power station, adjusts oil mass, just can electrodeless control stroke.After the utility model application of motor starts, the hydraulic starting oil well, the balanced type work done, the moment of torsion when oil well starts is the same during with operate as normal, and motor torque changes little, does not need big motor, saves electric energy.The utility model hydraulic pumping unit work done wire rope and counterweight wire rope are two, and the self-locking form is provided with, power consumption penalty such as avoid skidding.The utility model is provided with left and right two supports, and wherein a support can rotate around another support, makes things convenient for the maintenance of oil well.The utility model hydraulic pumping unit, simple in structure, the parts good tolerance, floor space is little, and running noises is little, is applicable to round-the-clock operating mode, changes wobble wheel footpath and bracket height, can be to the oil well operation of the various degree of depth.
