Description
Technical field
The present invention takes out linkage electric-machine directly-driven vertical oil-pumping machine for a kind of electric moving and unloading extension, belongs to electromechanical
Change new application.
Background technology
In oil field development, tradition double leval jib beam pumping unit is topmost exploitation means.According to not exclusively
Statistics, the whole world has mechanical oil well more than 150 ten thousand mouthfuls at present, and it is left that double leval jib beam pumping unit accounts for 90%
The right side, becomes the leading type of mechanical oil recovery.Along with the deterioration of earth environment, the mankind to efficient energy-saving, low-carbon (LC),
The demand of environmental protection is more and more urgent, all kinds of energy-savings material, does not shut down intelligence and adjusts ginseng, safe and environment-friendly balance
Balance vertical oil pump is born in succession, especially with the " ultra-low speed big torsional moment special-shape of CNPC's Wang Gang teaching inventive
Motor dragging and tower type high-efficiency low-consumption intelligent pumping unit " have originality and guide effect (ZL00246414.4,
ZL02257259.7、ZL200510123422.9、ZL200920222339.0、ZL201020111249.7)。
After above-mentioned patent, domestic occurring in that 3 kinds are imitated types the most successively, but its structure and principle do not have essence
Sexually revise.Compared with tradition double leval jib beam pumping unit, the energy-conservation 30-70% of Balance vertical oil-pumping machine,
Save material 30-60%, do not shut down intelligence and adjust ginseng to improve work efficiency more than 1000 times, be suitable to long stroke, low jig frequency
Working system, maintenance workload reduces more than 60%, and these obvious technical advantages determine Balance and stand
The development trend of the big substituted tradition double leval jib beam pumping unit of formula oil pumper.But sum up oil pumping in nearly 30 years
The development course of machine, technical advantage so significantly Balance vertical oil-pumping machine remains in middle and small scale and pushes away
In the wide stage, failing all the time to replace tradition double leval jib beam pumping unit, its restraining factors are as follows:
Although one is that conventional Balance vertical oil-pumping machine more traditional double leval jib beam pumping unit is greatly simplified,
