The utility model is characterized in that the motor stator (6) and the hollow axle rod (7) in the combined body (12) for assembling the combined body(12)are arranged in an oil well pipeline (1); a permanent magnetism mover is arranged in the hollow axle rod (7); a sealing element (5), an upper oil outlet valve (4), a pressure oil outlet (3) and an oil outlet pipe (2) are arranged at the upper end of the motor stator (6); the upper end of the oil outlet pipe(2) is provided with a manometer (15) which is connected with an oil outlet switch (16). The lower end of the motor stator(6)of the body is provided with a lower sealing element (8); a lower oil outlet valve (9) is to a pressure oil inlet (10) and an oil inlet valve (11); one side of the body(12)is provided with cables (13) and connected with a driving control box (14). The utility model has the advantages of simple structure, reliable functions, small volume, low energy consumption, low cost and high efficiency; the extracting oil has high pressure, which does not need to increase auxiliary oil pump in long range transmission.

Description

A kind of electromagnetic actuator device

One, technical field

The utility model belongs to a kind of plunger pump and the combined drive unit of motor, the main supporting oil production system that is used in the petroleum industry aspect.

Two, background technique

At present, the oil production system aspect petroleum industry uses plunger pump to recover the oil and adopts rope traction often, and to-and-fro motion is limited, and required motor power is bigger, and power consumption is bigger, inefficiency.And the former oil pressure that plunger pump is extracted out is low, needs constantly pressurize with auxiliary oil pump during long-range conveying, safeguards simultaneously, maintenance, administration cost be higher.

Three, summary of the invention

According to above-mentioned situation, the purpose of this utility model provides a kind of electromagnetic actuator device.It is the drive unit that adopts techniques of linear motor and the combination of hydraulicdriven plunger pump.Specific structural features is: Electromagnetic Drive linear electric motor housing is adopted the injection moulding sealing, to guarantee that burn into is not non-leakage in the underground solution of High Temperature High Pressure, body upper connects oil outlet tube, its linear electric motor axostylus axostyle adopts hollow circular-tube, as the oil pumping passage, at organism bottom and axostylus axostyle two ends up and down, be equipped with unidirectional make progress into and out of the fuel tap door.When axostylus axostyle moves upward, vacuum appears in the body, and crude oil promptly enters body from the oiling valve of organism bottom, and when axostylus axostyle moved downward, the crude oil in the body entered oil outlet tube from the outlet valve of axostylus axostyle lower end and upper end, promptly realized oil pumping.Axostylus axostyle pumps by the instruction that drive controller sends.Drive controller is installed in the control box, and control box is arranged in above space, the face of land or the control room.

The beneficial effects of the utility model are that simple in structure, reliable in function, volume are little, little power consumption, cost is low, efficient is high, do not need the auxiliary oil pump pressurization when the former oil pressure height of extracting out, long-range conveying.

Four, description of drawings

Fig. 1 is the novel structural representation of this usefulness;

Fig. 2 is the structural representation of the stator 6 of this device.

Among the figure 1, oil country tubular good, 2, oil outlet tube, 3, the pressure oil outlet, 4, go up outlet valve, 5, go up Sealing, 6, the motor stator of body, 7, dress permanent magnetism mover in the hollow axis pole, 8, lower seal, 9, following outlet valve, 10, the pressure oil inlet, 11, oiling valve, 12, body, 13, cable, 14, drive control box, 15, pressure gauge, 16, go out oil switch, 17, stator lasmination, 18, staor winding, 19, motor housing, 20, sealed pipe

Five, mode of execution

As shown in Figure 1, motor stator 6, the hollow axis pole 7 of Assembly organism 12 in the body of in oil country tubular good 1, installing 12, the permanent magnetism mover is housed in hollow axis pole 7, motor stator 6 upper ends be equipped with Sealing 5, on outlet valve 4 and pressure oil outlet 3 and oil outlet tube 2, in oil outlet tube 2 upper ends pressure gauge 15 is housed, and with go out oil switch 16 and be connected, lower seal 8, following outlet valve 9 are installed to pressure oil inlet 10 and oiling valve 11 in motor stator 6 lower ends of body 12, in these body 12 1 sides cable 13 is installed, and is formed by connecting with drive control box 14.

As shown in Figure 2, the structure of the stator 6 of this device is that stator lasmination 17 and staor winding 18 combinations are installed in motor housing 19, is sealed to form by sealed pipe 20, and stator lasmination 17 is used to produce magnetic force, makes magnetic force form circular shape and distributes; Staor winding 18 is to produce the stator power source, its formation decision motor thrust size, motor housing 19 is that the magnetic field that the adjacent stators lamination is produced constitutes closed magnetic circuit, and rise and support and seal action, sealed pipe 20 is to stop extraneous liquid to immerse in the staor winding, and and mover between produce magnetic suspension force.

If this device is when being installed on the oil well, and when hollow axis pole 7 moved upward, outlet valve 4 and following outlet valve 9 were closed on the axostylus axostyle, drives the interior crude oil of axostylus axostyle and moves upward.Vacuum occur in the body 12 this moment, and crude oil promptly enters body from the oiling valve 11 of organism bottom by pressure oil inlet 10; When hollow axis pole outlet valve 9 under the axostylus axostyle enters in the axostylus axostyle, the crude oil in the axostylus axostyle then enters oil outlet tube 2 from last outlet valve 4, pressure oil outlet 3.Under the control of control box 14 inner drivers, hollow axis pole 7 continuous high speed to-and-fro motion promptly realize the work of ceaselessly pumping.
