Description
Art
The utility model relates to a kind of hybrid efficient long stroke hydraulic pumping unit, and this machine belongs to bar hydraulic pumping unit
Class, is a kind of new-type oil recovery machiner in oil extraction in oil field technique.This owner to be made up of long stroke framework and efficient hydraulic system.
Background technology
Learn that long stroke pumping unit efficiency is higher than other types after deliberation with experiment, therefore very eurypalynous length occur recently
Stroke beam-pumping unit.But it is difficult to make long stroke machine, chain-type because old beam pumping unit limits by moment of torsion and walking beam length
Though machine can make long stroke, but structure is complicated, and the life-span is short, and efficiency is low, therefore there is no matured product at present and comes out in a large number.The machine
Use walking beam have big and simple speed increasing ratio and hydraulic pressure have efficiently and the feature of simple in construction designs a kind of hybrid height
Effect long stroke hydraulic pumping unit, its stroke is up to 10m, even more high.
Content of the invention
The purpose of this utility model is to propose a kind of hybrid efficient long stroke hydraulic pumping unit so that it is have stroke
Long, efficiency high, volume is little, lightweight, highly low, stroke, jig frequency can continuously adjust, when pumping can above fast lower slow and super,
The advantages such as disconnected load energy autostop warning, and steel 70% can be saved, make weight only have the 30% of former machine.And can accomplish without joining
Pouring weight formula balances.Another feature of the machine is to be operated inEnvironment in without heating and cool down.
Implementing technical measures of the present utility model is, this machine is by a long stroke framework and a set of efficient hydraulic system group
Becoming, its framework includes support, walking beam and front and back horse head.Hydraulic system includes multi-functional oil cylinder, 2～3 bladder storages in parallel
Energy device, exchange system and bar sensory perceptual system super, disconnected and oil sources.
In framework, the front pivot angle of walking beam is much larger than a radian, can be to 101 °, thus stroke is much larger than the front radius of walking beam
R, thus long stroke machine can be designed with short walking beam, in like manner the front radius of walking beam and the ratio of rear radius are also much larger than 1, can be to 5, this
Sample just can make that oil cylinder stroke is short and the hydraulic pumping unit of stroke length, to ensure the oil cylinder long-life.
When cylinder rod is descending, and i.e. horse head is up, 2～3 high pressure accumulators lead to cylinder upper cavity oil hydraulic oil and from
Oil sources simultaneously flows to the hydraulic oil of cavity of resorption in oil cylinder by reversal valve and is respectively acting on upper and lower two pistons so that it is produces and promotes donkey
Up makes a concerted effort, and when horse head to top dead-centre, the commutative ring on cylinder rod and following proximity switch are connected, therefore reversal valve
Commutation, the hydraulic oil of oil sources changes its course and flows into the middle epicoele of oil cylinder, promotes cylinder rod up, the hydraulic coupling now producing and sucker rod
The oil of epicoele is pushed back again accumulator by minimum polished rod load together that produce when descending, completes a cycle of oil pumping.Here store
Can not only make oil pumper improve efficiency by device, oil pumper also can be made to complete the automatic balance function without balancing weight.
In addition, the position of two proximity switches on cylinder rod side is continuously adjustable, thus the length of stroke can be continuous
Regulation.
Load stopping alarm system super, disconnected is made up of the Pressure gauge with high pressure and low tension contact switch.
Medium-sized electro-hydraulic reversing valve is made up of by brake system a 3-position 4-way.
Brief description
Embodiment shown below in conjunction with the accompanying drawings, the utility model is described in further detail.Wherein:
Fig. 1 is framework map of the present utility model, and Fig. 2 is hydraulic scheme of the present utility model.
Detailed description of the invention
Due to walking beam 2 in the utility model Fig. 1 pivot angle be much larger than a radian, can to 101 ° therefore stroke S long-range
In the front radius R of walking beam 2, thus constitute long stroke.The rear radius r of walking beam is much smaller than its front radius R, can arrive, make oil cylinder 5
Stroke L is much smaller than stroke S, thus increases the life-span of oil cylinder.Cylinder rod 4 shown in Fig. 2 is each at its on the way upper and lower two-end-point
Fill a proximity switch 13 and 14, cylinder rod fills a commutative ring 12, when this commutative ring 12 is close proximity to switch 13 or 14
Reversal valve 8 just changes oil circuit direction, makes cylinder rod inverted running, the position of this two proximity switches can with continuous moving, thus
Stroke can change continuously.Hydraulic oil needed for oil cylinder is from oil sources PS。
Two pieces of accumulators 6 in Fig. 2 are in parallel and communicate with cylinder upper cavity oil 7, and when the up oil pumping of horse head, cylinder rod to be propped
Maximum polished rod load, produces bigger lower thrust by the hydraulic oil in accumulator at cylinder upper cavity oil 7 for saving energy, and with from
Oil sources simultaneously pulls the up oil pumping of horse head by reversal valve 8 in the hydraulic coupling that middle cavity of resorption 9 produces together；Commutate when horse head to summit
Ring 12 and switch 13 connection, make oil circuit commutate, on minimum reconnaissance load is together with the hydraulic coupling from the middle epicoele 18 of oil sources
Push piston 10, advances the fluid in epicoele 7 in accumulator 6, thus completes the cycle of operation of an oil pumping.
17 is the oil pressure gauge with electric contact, and when the sucker rod in oil well is broken, load is prominent lets out, oil pressure huge fall therewith, because of
Electric contact 16 perception of this oil pressure gauge 17 simultaneously sends signal, makes that complete machine is vertical to stop, otherwise loads when Rock in Well blocks sucker rod
Power abruptly increase, the same perception of high-tension electricity contact 15 of oil pressure gauge 17 makes that complete machine is vertical to stop.
The function of brake system is to be completed medium-sized electro-hydraulic reversing valve 8 by 3-position 4-way, when receiving brake signal, changes
To valve 8 power-off immediately, spool returns to middle position and blocks 9 and 18 liang of chambeies simultaneously, therefore shuts down.
