Abstract
The utility model discloses a vacuum ground oil pump, which is composed of a cam body, a plurality of plunger oil pumps, a current collector, a dispersion body and a support frame, wherein, the plunger oil pumps are rolled in a groove which is arranged in the cam body and the depth of which is approximate to a sine curve by a roller carrier which is arranged on the front end of a special-shaped pull press shaft. Plungers can move repeatedly in plunger barrels by forcibly, and the cavities of the plunger barrels are changed to vacuum. Because a plurality of barrels are operated together, two plungers and plunger barrels can form vacuum cavities which can absorb gas at any hour, and two plungers and plunger barrels can exhaust absorbed gas. High vacuum can be formed quickly by repeatedly and continuously pumping. The vacuum ground oil pump can cause high negative pressure to oil storing layers, and can achieve the purpose of dumping crude oil. The utility model can be arranged on ground and can alternately operate with a plurality of plunger oil pumps. The utility model has the advantages of convenient maintenance, simple structure, stable running, high efficiency and energy saving.
Description
The utility model belongs to the petroleum machinery technical field.
Since the establishment of the nation, along with the exploitation of many finds, the oil production rate of China increases year by year.But the oil production equipment of China does not all improve from structure and principle for many years, still continues to use the plunger oil-well pump of foreign country.This plunger oil-well pump is installed in the down-hole hundreds of even goes up dark underground of km, pumping unit makes a round trip and can only take out once oil, when breaking down, oil well pump be proposed and can keep in repair from the down-hole, so have that pumping efficiency is low, a complex structure, power consumption is big, maintenance is inconvenient deficiency.
The purpose of this utility model provide a kind of setting on the ground, simple in structure, efficient is high, energy saving, vacuum easy to maintenance oil well pump on the ground.
The technical solution of the utility model is: be fixed with 4-8 plunger oil-well pump on the circumference on fore poppet and the back poppet symmetrically, plunger oil-well pump is made up of sleeve and reducing plunger, is linking cam body at the front end of plunger oil-well pump by coupling, special-shaped tension and compression axle, turning rolls; Near sinusoidal curvilinear body and interior near sinusoidal curvilinear body outside on cam body, being equipped with, it is the groove of near sinusoidal curvilinear motion that inside and outside near sinusoidal curvilinear body forms the degree of depth, turning rolls is installed in the near sinusoidal curvilinear groove; Cam body is installed on the line shaft, line shaft by Bearing Installation in fore poppet; Feed liquor mechanism is installed in the rear end of plunger oil-well pump, and feed liquor mechanism communicates with dispersion by hollow bolt, has a plurality of oil pockets to communicate in the dispersion, and communicates with a minute raw edge; Side at plunger oil-well pump is provided with oil outlet, and oil outlet communicates with collector by fuel-displaced mechanism; In oil-feed mechanism and fuel-displaced mechanism valve ball is housed respectively, valve ball is pressed on filler opening or the oil outlet by spring; Thin portion at the reducing plunger has 6-8 equidistant ring-type choked flow groove.
Working principle of the present utility model is: dividing raw edge to be connected on the well head oil pick-up tube, driven by motor cam body, cam force plunger to move reciprocatingly in plunger tube.When wherein two relative plunger tubes of plunger were pulled outwardly, the cavity of plunger tube became vacuum, and the gas in the oil pick-up tube is inhaled into vacuum chamber, when plunger when the plunger tube direction is moved, this part gas promptly is discharged from.Owing to work simultaneously for many, each all has two plungers and plunger tube formation vacuum chamber to suck gas constantly in oil pick-up tube, the gas that the vacuum chamber that also all has two plungers and plunger tube to form sucks is discharged from, gas in the oil pick-up tube is once and again extracted out like this, very fast formation high vacuum, oil reservoirs are caused high negative pressure, therefore the continuous sucking-off of intracrustal crude oil.
Good effect of the present utility model is:
1, the utility model is worked on the ground, so easy to maintenance;
2, the utility model is because a plurality of plunger oil-well pump alternations, have simple in structure, operate steadily, the advantage of efficient height, energy saving;
3, write off ground pumping unit and underground plunger pump.
Fig. 1 is a structural representation of the present utility model.
Be described in detail the utility model below in conjunction with drawings and Examples.
Can be clear that with reference to figure 1 the utility model is fixed with 6 plunger oil-well pumps 10 symmetrically on the circumference of fore poppet 9 and back poppet 15, plunger oil-well pump 10 is made up of plunger tube 10a and reducing plunger 11; Front end (cam body end) at plunger oil-well pump 10 is linking cam body 2 by coupling 8, special-shaped tension and compression axle 7 and turning rolls 4; Near sinusoidal curvilinear body 3 and outer near sinusoidal curvilinear body 5 on cam body 2, being equipped with, inside and outside near sinusoidal curvilinear body forms the degree of depth for pressing the groove 6 of near sinusoidal curvilinear motion, and turning rolls 4 rolls near sinusoidal curvilinear groove 6; For avoiding special-shaped tension and compression axle 7 distortions and turning rolls 4 and curvilinear groove scratching, in coupling 8, special-shaped tension and compression axle 7 can freely rotate special-shaped tension and compression axle 7 by Bearing Installation, makes turning rolls 4 along normal rolling the in the near sinusoidal curvilinear groove 6.Cam body 2 is installed on the line shaft 1, line shaft 1 by Bearing Installation in fore poppet 9; Oil-feed mechanism 16 is installed in the rear end of plunger oil-well pump 10, and oil-feed mechanism 16 communicates with dispersion 19 by hollow bolt 18, and dispersion 19 has 6 oil pockets 20 to communicate, and communicates with a minute raw edge (oil-feed gas port) 21; Side at plunger oil-well pump is provided with oil outlet, and oil outlet communicates with collector 22 by fuel-displaced mechanism 13, and collector 22 communicates with the fuel-displaced mechanism 13 of each plunger oil-well pump 10; In oil-feed mechanism 16 and fuel-displaced mechanism 13 valve ball 17 and 14 are housed respectively, valve ball 17 and 14 is pressed on filler opening or the oil outlet by spring respectively; Thin portion at reducing plunger 11 has 8 equidistant ring-type choked flow flutes 12, prevents that gas-liquid from flowing backwards, and plays decompression.
Working procedure of the present utility model is: will divide raw edge (filler opening) to be connected on the well head oil pick-up tube, motor is connected on the line shaft, when cam body 2 rotates, force rolling frame 4 near sinusoidal curvilinear groove 6, to roll, special-shaped tension and compression axle 7 moves reciprocatingly plunger 10 in plunger tube 10a, when plunger 10 is pulled outwardly, the cavity of plunger tube 10a becomes vacuum, under the effect of negative pressure, valve ball 17 leaves filler opening, gas-liquid oil pocket 20 in dispersion 19 that come in from a minute raw edge (filler opening) 21 this moment by filler opening, enters plunger tube 10a inner cavity; When plunger 10 inwardly advanced, valve ball 14 left oil outlet, and valve ball 17 is closed filler opening, and vapour-liquid enters fuel-displaced mechanism 13, discharged from fuel-displaced mechanism 13, by oil outlet tube 23 outflows of collector 22, finished a work cycle.Owing to work simultaneously for many, each all has two plungers and plunger tube formation vacuum chamber to suck gas constantly in oil pick-up tube, the gas that the vacuum chamber that also all has two plungers and plunger tube to form sucks is discharged, gas in the oil pick-up tube is constantly extracted out repeatedly like this, very fast formation high vacuum, oil reservoirs are caused high negative pressure, therefore the then interior continuous sucking-off of crude oil of the earth's crust.
