With reference to embodiment, this utility model is further illustrated, following embodiments are illustrative, be not limited
It is impossible to limit protection domain of the present utility model with following embodiments.
A kind of energy-conserving hydraulic formula oil rig, as shown in Figure 1, 2, 3, innovation of the present utility model is: inclusion Hydraulic Station,
Support 9 and oil pumper, described oil pumper includes two hydraulic cylinders 7,8 () in Fig. 3 (12), this two hydraulic cylinders be all vertically arranged and
The rodless cavity end of the two connects, and the piston rod 5 of hydraulic cylinder above connects described pedestal upper end 4, underlying liquid
Piston rod 19 bottom 10 of cylinder pressure is used for the sucker rod in pit shaft below connecting bracket, and the rod chamber 17 of two hydraulic cylinders is all logical
Cross the fuel tank 1 that the switch valve group 12 in Hydraulic Station and oil pump 13 connect in Hydraulic Station, the rodless cavity 18 of two hydraulic cylinders mutually interconnects
Logical, the piston rod of underlying hydraulic cylinder runs to and triggers upper limit position switch respectively when the top or bottom and lower limit is opened
Close ((13) .1 in Fig. 3 and (13) .2).
In the present embodiment, two accumulators 3 in described switch valve group connection liquid pressure station (include 3.1 Hes in Fig. 2
3.2).Described Hydraulic Station include two-way pump 13, motor 2, fuel tank 1, accumulator 3, framework 16 and electromagnetic valve ((7) .1 in Fig. 3,
(7) .2 and (7) .3), described two-way pump, motor, fuel tank, accumulator and electromagnetic valve are arranged in framework, and Motor drive two-way pump revolves
Turn, the oil-in of two-way pump connects fuel tank, an oil-out of two-way pump connect an accumulator 3.1 (the (9) .1 in Fig. 3) and
One end of one electromagnetic valve (the (7) .1 in Fig. 3), another oil-out of double pump connects another accumulator (the (9) .2 in Fig. 3)
With one end of another electromagnetic valve (the (7) .2 in Fig. 3), the other end 15 of two electromagnetic valves is by oil pipe 6 two hydraulic cylinders of connection
Rod chamber.
One accumulator 3.1 (the (9) .1 in Fig. 3) pressure in parallel on the oil pipe and an oil-out of two-way pump between
Force transducer () in Fig. 3 (10), a list in parallel on the oil pipe between another oil-out of another accumulator and two-way pump
To choke valve () in Fig. 3 (8).
The working condition of oil pumper is mainly made up of two parts: load declines and oil pumping lifting.Depression of order section under a load, takes out
Oil machine hydraulic cylinder no pressure, the piston rod of hydraulic cylinder is subject to load effect to be drawn out.When Oil cylinder of pumping is completely pulled out of, touch
Give limit switch, the load decline stage terminates, and oil pumper enters the oil pumping improvement stage.In the oil pumping improvement stage, in two-way pump
Under the dual fuel feeding effect with accumulator, pumping unit hydraulic cylinder pressure rises to rated pressure, overcomes carrying, and piston rod is retracted,
Pull sucker rod oil pumping.When pumping unit hydraulic cylinder is fully retracted, trigger upper limit position switch, the oil pumping improvement stage terminates, oil pumping
Machine release, is again introduced into loading the decline stage.
Motor, dt1, dt2 and dt3 opening during above-mentioned two (+) and close (-) state be shown in Table 1:
| Working condition | Motor | dt1 | dt2 | dt3 |
| Original state | — | — | — | — |
| Oil pumping lifting | + | + | — | + |
| Load declines | + | — | + | + |
Table 1: the state diagram of various process
Specific work process is as shown in Figure 3:
1. under original state, oil pumper is acted on by load, and two piston rods are fully extended, and (3) motor starts, and two-way pump is (4)
From fuel tank (1) interior oil suction, because now only electric magnet dt3 obtains electric, (7) .3 state switchs to end two position two-way valve, and fluid is only for operating
Accumulator can be filled with (9) in .1；
2. when (9) .1 inner fluid is full of accumulator, pressure transducer (10) sending signal, before adding, oil pumper is stretched completely
Trigger lower position switch (13) .2 sending signal when going out, confirm through two signals, oil pumper enters oil pumping lifting state: electric magnet
Dt1 obtain electric, two position two-way valve (7) .1 state switch to connect, two-way pump (4) with accumulator (9) .1 jointly be oil pumper (12) fuel feeding, take out
Oil machine piston rod is retracted, oil pumper lifting oil pumping；
3. when oil pumper piston rod is fully retracted, trigger upper travel switch (13) .1 sending signal, oil pumper enters negative
Carry decline state: electric magnet dt1 must not electricity, dt2 obtains electric, and (7) .1 state switchs to end two position two-way valve, and (7) .2 state switchs to even
Logical, oil pumper release, in the presence of external loading, (9) in .2, a part is logical for part inflow accumulator for oil pumper inner fluid
(5) .1 flows back to fuel tank to cross overflow valve, and meanwhile two-way pump (4) still in oil suction, fluid is filled with accumulator (9) in .1；
4. when oil pumper piston rod is fully extended, and accumulator is when (9) .1 inner fluid is full of, and oil pumper is again introduced into
Oil pumping lifting state, its working condition is identical with 1, but it should be noted that now, two-way pump (4) can be from accumulator (9) .2 interior suction
Oil, because the fluid in accumulator (9) .2 is with pressure, the power of two-way pump (4) oil suction can substantially reduce.
The implication of other labels in Fig. 3: (2) .1 is check valve, (6) .1 and (6) .2 be pressure measuring tie-in, (11) for pressure gauge.
Above-mentioned upper limit position switch and lower position switch may be mounted at the top and bottom of bracing frame 11, perpendicular on bracing frame
Directly be slidably installed a trigger member, and this trigger member passes through assembly pulley, bracing wire is connected with hydraulic cylinder, the position on the vertical direction of hydraulic cylinder
Put the trigger member that change is delivered on bracing frame by bracing wire, assembly pulley, triggered by it install on bracing frame above with
Two limit switches of lower section.One electric cabinet 14 is also installed on framework.
This utility model, the rodless cavity of two hydraulic cylinders is connected with each other, and then entirety is vertically arranged in support, cancels
The part such as caput Equi Asini of the prior art, walking beam, connecting rod, balance weight, greatly simplified the structure of oil pumper itself, in addition,
The driving of oil pumper is completed by Hydraulic Station, and during non-oil pumping state, accumulator carries out energy storage, and during oil pumping state, accumulator releases energy,
And oil pumper energy storage of producing when declined by ground pressure load effect, it is to avoid in prior art, motor is when driving counterweight
Energy dissipation that is to say, that oil pumper itself and drive part are all improved, make overall volume-diminished, energy profit
With more rationally, work efficiency is higher.
