Description
Technical field
This utility model is related to a kind of hydraulic system, more particularly, to a kind of hydraulic pressure system driving black soy sauce oil machine with single Hydraulic Station
System.
Background technology
At present, oil field widely uses crank-balanced pumping unit, and in actual motion, upstroke work done is an up
Weight such as bar, pump, fluid column and overcome frictional force, and down stroke work is the weight lifting counterweight of collaborative bar, pump free-falling
Block.This just illustrates oil pumper in actual motion, and the acting that upper and lower stroke all needs defines the waste of portion of energy.
Meanwhile, in the course of the work, motor part acting is to drive crank balance to current crank-balanced pumping unit
The balance weight of formula oil pumper moves and overcomes the mechanical resistance within reduction box, defines the waste of portion of energy.
Content of the invention
A kind of single Hydraulic Station is provided to drive black soy sauce oil machine hydraulic system, mesh in order to solve above-mentioned technical problem this utility model
Be two oil pumpers of a hydraulic pressure stand control, save initial outlay expense.
Drive black soy sauce oil machine hydraulic system for reaching above-mentioned purpose this utility model list Hydraulic Station, including Hydraulic Station, Hydraulic Station
It is connected with electro-hydraulic reversing valve input, two outfans of electro-hydraulic reversing valve pass through high pressure line and the first balanced valve and the respectively
Two balanced valves connect, and the first balanced valve and the second balanced valve are connected with first hydraulic cylinder and second hydraulic cylinder by pipeline respectively.
Electro-hydraulic reversing valve is m type function electro-hydraulic reversing valve.
It is provided with stroke lever and induction apparatuss in the outside of first hydraulic cylinder and second hydraulic cylinder.
The utility model has the advantages of: because hydraulic system is only done work in oil pumper upstroke, down stroke is by oil pumping
Bar, pump deadweight complete, so this hydraulic cylinder down stroke when, Hydraulic Station can drive another hydraulic cylinder, drives another oil pumping
Machine does work in upstroke, and not only energy-conservation also greatly reduces the initial stage Meteorological of equipment.One Hydraulic Station is electro-hydraulic by one
Reversal valve is respectively two hydraulic pressure oil supply cylinders, and a hydraulic cylinder rises, and another hydraulic cylinder declines simultaneously, otherwise so.For protecting
Hold hydraulic cylinder steadily to decline, during oil return, add direct controlled type balanced valve, the distance of stroke is set by stroke lever and induction apparatuss.And then
Realize driving the purpose of two oil pumpers work, that is, by two oil pumpers of a hydraulic pressure stand control, can save very big initial
Investment cost.

Specific embodiment
With reference to embodiment, this utility model is described further.Following examples are only tool of the present utility model
Body embodiment, but design concept of the present utility model is not limited thereto, all carries out non-reality using this design to this utility model
The change of matter, all should belong to the behavior invading this utility model protection domain.
This utility model list Hydraulic Station drives black soy sauce oil machine hydraulic system as shown in the figure, includes Hydraulic Station 7, Hydraulic Station 7 and
Electro-hydraulic reversing valve 6 input connects, two outfans of electro-hydraulic reversing valve 6 pass through respectively high pressure line and the first balanced valve 4 and
Second balanced valve 5 connects, and the first balanced valve 4 and the second balanced valve 5 pass through pipeline and first hydraulic cylinder 1 and second hydraulic cylinder respectively
2 connections.
Electro-hydraulic reversing valve 6 is m type function electro-hydraulic reversing valve.
It is provided with stroke lever and induction apparatuss 3 in the outside of first hydraulic cylinder 1 and second hydraulic cylinder 2.
Operation principle of the present utility model:
One Hydraulic Station passes through an electro-hydraulic reversing valve and is respectively two hydraulic pressure oil supply cylinders, and a hydraulic cylinder rises, simultaneously
Another hydraulic cylinder declines, otherwise so.For keeping hydraulic cylinder steadily to decline, during oil return, add direct controlled type balanced valve, stroke
Distance set by stroke lever and induction apparatuss.
Its work process is: Hydraulic Station is in the state of operating at full capacity all the time.
The yv1 end energising of electro-hydraulic reversing valve 6, valve is in left position, and the pressure oil of hydraulic pump output enters first hydraulic cylinder 1
Cavity of resorption, first hydraulic cylinder 1 plunger rod stretches out, and the sucker rod lifting of this oil pumper, when reaching up stroke summit, completes once
Oil pumping, induction apparatuss start, and electro-hydraulic reversing valve yv2 is energized, and valve commutates, and is in right position.The pressure oil of hydraulic pump output enters second
The cavity of resorption of hydraulic cylinder 2, second hydraulic cylinder 2 plunger rod stretches out, by the sucker rod lifting of another oil pumper.In second hydraulic cylinder 2
While just stretching out, first hydraulic cylinder 1 declines under sucker rod action of gravity, and balanced valve controls hydraulic cylinder decrease speed.
When second hydraulic cylinder 2 reaches up stroke summit, complete once to pump, induction apparatuss start, and electro-hydraulic reversing valve yv1 end is again
The commutation of secondary energising, the pressure oil of hydraulic pump output is again introduced into the cavity of resorption of first hydraulic cylinder 1, and hydraulic cylinder 1 plunger rod stretches out, will
The sucker rod lifting of this oil pumper.
While first hydraulic cylinder 1 is just stretched out again, hydraulic cylinder 2 declines under sucker rod action of gravity, balanced valve control
Hydraulic cylinder decrease speed processed.
So repeatedly, double oil pumping machine oil pumping operations are completed.
