Plant engineering field, its technology relate to the fields such as Design of Mechanical Structure, Hydrostatic secondary control and new energy.
Background technology
Show according to the study, the electric energy of oil production equipment consumption accounts for more than the 20% of whole Oil Production power consumption, in face of increasingly serious
Energy crisis, new oil production equipment is improved or develops to realize that energy-conservation seems extremely important.And traditional beam type is taken out
Not only complicated in mechanical structure, manufacturing cost are big for oil machine, and operating efficiency is very low, at home typically only 12-23%, and external
This kind of oil pumper also averagely be only 30% or so；On the contrary, hydraulic pumping unit due to light weight, small volume, length of stroke and
Number of strokes can step-less adjustment the features such as, especially its operating efficiency is high, easily realizes energy-conservation and is rapidly developed it.In mesh
In preceding research, realize that the method for hydraulic pumping unit energy-conservation is mainly and the gravitational potential that sucker rod falls first is reclaimed by accumulator
Can, then re-used when sucker rod rises and pumped, but the shortcoming of this method, which is multiple energy, to be changed so that energy-saving effect
Decline, and add energy conversion component so that complicated, cost increase.Another method is so as to drop using counterweight
Low installation power, but this method causes oil pumper to be greatly reduced in the power needed for constant velocity stage, and fluid power system is low
Operating efficiency under power is relatively low.Therefore, the present invention proposes new multi-energy hybrid power hydraulic pumping unit.
The content of the invention
In order to solve traditional beam pumping unit and current hydraulic pumping unit shortcoming as described above, present invention employs double
The Design of Mechanical Structure that well is mutually balanced, or the knot that can be balanced in the use area being not suitable for using twin-well using individual well plus counterweight
Structure is designed, while drive system employs the hydraulic constant pressure network hydrostatic Secondary Regulation Technology and small-sized scene of no restriction loss mutually
The new energy technology of electricity is reissued, oil pumper is hydraulically operated in boost phase and can adjust in real time to adapt to loading demand, and it is even
Power direct drive is provided by wind and solar hybrid generating system under fast stage low-power operating mode, so as to realize the purpose of efficient energy-saving.
Patent of the present invention solves the technical scheme that its technical problem used：One is the structure design of energy-conservation.The multipotency
Source hybrid-power hydraulic oil pumper is using twin-well balanced arrangement or individual well and counterweight balanced arrangement, and its main distinction is that individual well adds and matched somebody with somebody
The configuration of weight is not pumped when sucker rod is returned, and twin-well configuration can be pumped with continuity.Two be to use constant pressure network hydraulic pressure two
Secondary regulation technology, hydraulic pump exports hydraulic oil to constant pressure network, and secondary component motor/pump can in real time be adjusted according to loading demand
Displacement size, system realizes energy-conservation without restriction loss and spill losses and the real-time change for adapting to load.Three be renewable energy
Fluid power system is installed in the utilization in source, driving roller one end, and the other end is then installed and provides energy by wind and solar hybrid generating system
The drive system of amount, load is hydraulically operated in powerful boost phase, and the constant velocity stage run in small-power is then by wind
Light power generating system drives.
The energy-saving effect of patent of the present invention is, on the premise of system effectiveness is considered, when twin-well is run, and sucker rod accelerates rank
Section consumption power is maximum, and installation power is 25 kW, smaller in constant velocity stage's consumption power, and theoretical calculation power is 2.2 kW, dress
Acc power reduces 23.3%, the shorter boost phase time is 2 s compared with the average installed power 32.6kW of existing oil pumper,
During into longer constant velocity stage, system be switched to wind and solar hybrid generating system provide energy, and wind energy and luminous energy be cleaning,
Efficient regenerative resource, therefore its energy-saving effect is extremely notable.
Brief description of the drawings

Embodiment
【Embodiment 1】
As shown in figure 1, the novel energy-conserving hydraulic pumping unit mechanical structure unit mainly by driving roller, frame, sucker rod 1 and is taken out
The composition such as beam hanger 2, steel wire rope, two crown sheavies.Two sucker rods are after crown sheave by steel wire rope connection and balanced, symmetrical
Driving roller both sides are arranged in, and drive the steel wire rope of both sides on roller to wind in the opposite direction, so that when driving roller
When the sucker rod of side rises oil pumping, the sucker rod of opposite side synchronously declines, and forms the oil pumping of twin-well alternately operating, and reach continuous
Property oil pumping., can be the oil pumping of driving roller side in addition, the oil-producing region for being not suitable for installing two oil wells in nearer distance
Bar is changed to counterweight, and the course of work does not change, and is simply continuously pumped from twin-well and is changed into individual well oil pumping.
【Embodiment 2】
As shown in Fig. 2 the drive system of the novel energy-conserving hydraulic pumping unit is by hydraulic pressure Hydrostatic transmission and small-sized wind light mutual complementing
