Description
Technical field
The present invention relates to the energy savers of pumping unit adjustment in production of recovering the oil.
Background technology
Pumping unit is the capital equipment of oil field machinery oil and the main energy consumption equipment in oil field.For many years, in pumping unit
On also take many energy conservation measures, but its effect is all less desirable.Due to paying weight in the four-bar mechanism of pumping unit
Be for the purpose of with balancing in well hanger gravity, if suspended weights are more than weight of object in well, when pumping unit horsehead downlink,
Motor load becomes smaller, and then increases when uplink.The energy that the energy of downlink saving consumes more far from counteracting uplink, and cause
Motor job insecurity influences motor service life.
Invention content
The present invention is that there are one infusion pumps 1 for dress among walking beam on pumping units 6, and the both ends of infusion pump 1 are respectively provided with magnetic force and change
It is connected to valve 2A, 2B, magnetic change valve with both ends fluid reservoir 8 by woven hose 7, flow regulating valve 3 there are one dresses on woven hose 7,
In the lower part of walking beam on pumping units 6 equipped with preceding reversing switch 4, rear reversing switch 5.
It can be with pumping unit donkey the advantage of the invention is that providing one kind in the case where former balance of well pumping unit device is constant
Head moves up and down and the balancing device of variation, the i.e. transformation using liquid weight at walking beam both ends make pumping unit horsehead move downward
When before weight, when moving upwards behind weight reduce motor load and energy-efficient purpose to reach.
Description of the drawings
Fig. 1 is the front view of the present invention；
Fig. 2 is to adjust weighing apparatus device in walking beam top layout figure；
Fig. 3 is liquid flow schematic diagram
Specific implementation mode
Present invention will be explained in further detail with reference to the accompanying drawings and embodiments.
As shown in Figure 1, 2, 3, energy-saving balancing device for beam-pumping unit is that there are one infusion pumps 1 for dress among walking beam on pumping units, defeated
Liquid pump both ends are respectively provided with magnetic change valve 2A, a 2B, and reversal valve is connected by one section of woven hose 7 with both ends fluid reservoir,
For dress there are one flow regulating valve 3, infusion pump is continuous work on woven hose, and liquid changes flow direction by two reversal valves, works as horse head
When in top dead-centre, both ends liquid tank level is equal, and because underground weight is zero in this movement velocity, pumping unit is hard most at this time
Small, reversal valve 2B is in pump inlet state of closing, and 2A is then in and opens pump discharge state, and front end liquid storage pot liquid starts to inject
Rear end fluid reservoir.When horse head, which is run to walking beam, to be horizontal, rear end liquid tank level highest, in no tune weighing apparatus device
When, motor load is maximum.Since the weight of rear end high liquid level fluid reservoir is more than front end, so diligent peak-peak is reduced, this
When after reversing switch 5 open, preceding reversing switch 4 simultaneously closes off, and two commutation magnet valves commutate simultaneously, and rear end liquid storage pot liquid starts
Forward end fluid reservoir inject, until when walking beam level complete a commutation process, and two work done peak values of pumping-unit motor also by
It reduces, reduces motor power consumption, the effect of flow regulating valve 3 is can to limit inflow-rate of water turbine for the pumping unit of different model, is wanted with reaching
The counterpoise asked.Although infusion pump work done also consumes certain energy, more than the electricity for reducing pumping unit electricity consumption peak value saving
Much less.Because pumping unit selects matching motor to be calculated with power consumption peak value maximum, therefore using can after this law balancing
Again smaller power motor is selected.
