Description
Technical field
The utility model relates to a kind of oil field equipment, especially for the energy-saving hydraulic resistance balance post beam-pumping unit of oil field oil recovery.
Background technology
People can know from present data, and the balance of beam-pumping unit is to add balance weight iron on the beam-pumping unit crank, when oil pumper is worked, and the part gravity of sucker rod when load when partly rising and decline in order to balanced oil extractor.But this structure constitutional balance effect is bad, and not only very power consumption when adjusting equilibrant force, needs mobile counterweight iron, and so more aggravated energy consumption, with regard to the more common two horse head beam-pumping units of present use, also still there is the excessive problem that consumes energy in unusual difficulty.
Summary of the invention
The purpose of this utility model provides a kind of new hydraulic resistance balance post beam-pumping unit, it has removed Ben Chong De Minus speed device, balance weight and crank-link mechanism on traditional oil pumper, adopted hydraulic power system, telescopic oil cylinder and hydro-cushion device to be combined into holistic device, the drive walking beam moves up and down, it can not only provide more stable lifting power and equilibrant force for hydraulic resistance balance post beam-pumping unit, and can be according to condition of construction, adjustment power reaches economize on electricity and energy-conservation effect easily.
This practical technical scheme is: a kind of hydraulic resistance balance post beam-pumping unit, comprise hydraulic resistance balance post, horse head, walking beam, support, oil pumping unit base and sucker rod, this walking beam afterbody links to each other with support, hydraulic resistance balance post upper end is hinged with walking beam, lower end and oil pumping unit base are hinged, and upper link point is on the walking beam between support and the horse head.
This hydraulic resistance balance post is cut down and is constituted by oil cylinder, piston rod, balancing pole, balance tank, gas-accumulating tank, power oil tank, cross over pipe, oil pipe, motor, oil pump, distribution, the epicoele of gas-accumulating tank is equipped with high pressure nitrogen, cavity of resorption is equipped with hydraulic oil, and the cavity of resorption by cross over pipe UNICOM balance tank, motor, oil pump link to each other with hydraulic oil by oil pipe, this distribution is cut down hydraulic oil is sent to the epicoele and the cavity of resorption of oil cylinder by oil pipe respectively from the power oil tank, and piston rod connects balancing pole by piston.
Description of drawings
Fig. 1 is the structure chart of the utility model embodiment.
Fig. 2 is the structure chart of hydraulic resistance balance post among Fig. 1.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 description of symbols: 1-hydraulic resistance balance post; The 2-horse head; The 3-walking beam; The 4-support; The 5-oil pumping unit base; The 6-sucker rod.
Fig. 2 description of symbols: 7-piston rod; The 8-oil cylinder; The 9-piston; The 10-balancing pole; The 11-gas-accumulating tank; The 12-high pressure nitrogen; 13-hydraulic oil; The 14-cross over pipe; The 15-balance tank; 16-oil pipe: 17-distribution is cut down; The 18-oil pump; The 19-motor; The 20-oil inlet pipe; The 21-oil storage tank.
See also Fig. 1, the utility model hydraulic resistance balance post beam-pumping unit, comprise hydraulic resistance balance post 1, horse head 2, walking beam 3, support 4, oil pumping unit base 5 and sucker rod 6, described support 4 bottoms are installed on the oil pumping unit base 5, the top links to each other with walking beam 3, the upper end of described hydraulic resistance balance post 1 and walking beam 3 hinge joints, lower end and oil pumping unit base 5 are hinged, and upper link point is on the walking beam 3 between support 4 and the horse head 2.
See also Fig. 2, described hydraulic resistance balance post 1 by piston rod 7, oil cylinder 8, piston 9, balancing pole 10, gas-accumulating tank 11, high pressure nitrogen 12, hydraulic oil 13, cross over pipe 14, balance tank 15, oil pipe 16, distribute cut down 17, oil pump 18, motor 19, oil inlet pipe 20, oil storage tank 21 form.Described gas-accumulating tank 11 epicoeles are equipped with high pressure nitrogen 12, and cavity of resorption is equipped with hydraulic oil 13, and these gas-accumulating tank 11 cavity of resorptions are connected by the cavity of resorption of a connecting pipe 14 with balance tank 15, and piston rod connects balancing pole by piston.Described motor 19 drives oil pump 18, with the hydraulic oil 13 in the oil storage tank 21, enter in the oil pump 18 by oil inlet pipe 20, further enter to distribute and cut down 17 by oil pipe 16, and cut down 17 by distribution and enter the epicoele and the cavity of resorption of oil cylinder 8 respectively by other oil pipe 16 according to duty, in addition, the bottom of oil cylinder 8 is a balance tank 15.
See also Fig. 1 and Fig. 2, motor 19 drives oil pump 18, and the hydraulic oil 13 in the oil storage tank 21 is assigned to the cavity of resorption of oil cylinder 8 via distributing valve 17, so only needs less thrust just can make horse head 2 up.When horse head 2 is up, the hydraulic oil 13 of gas-accumulating tank 11 cavity of resorptions of hydraulic resistance balance post 1 enters the cavity of resorption of balance tank 15 by communicating pipe 14,13 pairs of balancing poles of hydraulic oil 10 produce thrust upwards, and then produce thrust upwards by 9 pairs of piston rods of piston 7, balance whole gravity of sucker rod 6 and the lifting force of part crude oil liquid in the oil well.When horse head 2 is descending, under the action of gravity of sucker rod 6, it is descending that oil cylinder 8 epicoeles also only need less pressure just can oppress piston rod 6, thereby piston 9 and balancing pole 10 are descending, hydraulic oil 13 in the balance tank 15 enters in the gas-accumulating tank 11 by cross over pipe 14, when horse head 2 rises, repeat a process again.
Hydraulic resistance balance post beam-pumping unit of the present utility model, setting by hydraulic resistance balance post 1, can load Dao the few oil pumper of Minus by Da, purpose of energy saving, the working conditions change of root a tree name oil well is in addition adjusted the pressure size of hydraulic resistance balance post 1 inner high voltage nitrogen 12, also just changed the size of equilibrant force, thereby obtain better power savings, it has removed Ben Chong De Minus speed device, balance weight and crank-link mechanism on traditional oil pumper, has alleviated the weight of oil pumper.
