Abstract
The utility model belongs to an electromechanical product, in particular to a rodless driving mechanism for a reciprocating oil well pump. The utility model is realized in the way (such as the diagram) that the rodless driving mechanism for a reciprocating oil well pump comprises a linear electric motor, a space sealing pipe (11) between the linear electric motor and a reciprocating pump and a reciprocating type oil well pump. The linear electric motor comprises a sealing outer shell (1), an upper and a lower end covers (12), a spindle iron core (2), a three-phase spindle winding (3), a hollow mover guideway (4), an upper and a lower damper springs (5), an upper and a lower position sensors (6), a hollow mover iron core (7), a mover winding (8) and a driving connecting rod (9) fixed with a mover. When the three-phase spindle winding is communicated with three-phase alternating current, an alternating magnetic field can be generated in the mover iron core. Induction current is generated in a mover coil; the induction current is under a stress in a magnetic field, driving the mover to move. When the mover moves to an upper and a lower commutation points, the position sensor sends out a commutation signal controller to control commutation of the linear electric motor. Thereby, a reciprocating pump piston is driven to move reciprocatingly to pump crude oil onto the ground. When the dynamic force produced by a single motor is insufficient, the mode of multi-stage relay can be taken.
Description
The utility model belongs to electronic product, and particularly a kind of reciprocating oil-well pump does not have the bar driving mechanism.
At present, oil recovery generally adopts beam pumping unit, tower-type pumping unit to drive with reciprocating pump.These driving mechanisms have common characteristics, and promptly the sucker rod that Fu Za ground mechanism all will be by last km is passed to reciprocating pump in the well with power.These driving mechanisms need a large amount of steel, therefore, and the cost height.These driving mechanisms not only cause efficient low but also because sucker rod flexible causes throw of pump to reduce significantly with the increase of the pump degree of depth down because complicated ground mechanism is arranged, the efficient of pumping unit is further reduced, cost for oil production is further strengthened and influence the economic effect of enterprise.
Goal of the invention of the present utility model is to provide a kind of reciprocating oil-well pump not have the bar driving mechanism according to the problems referred to above, and this driving mechanism is by directly driving reciprocating pump with the together following linear electric motor in oil well of pump by the drive link that is connected on linear motor rotor and the reciprocating pump pull bar.Owing to cancelled complicated ground mechanism and sucker rod, therefore, can save material, reduce cost, raise the efficiency, simultaneously throw of pump is being had in one's pocket.
Accompanying drawing is that reciprocating oil-well pump does not have bar driving mechanism schematic representation.The utility model is to realize (as figure) like this: reciprocating oil-well pump does not have space sealing pipe (11) and reciprocating oil-well pump composition between bar driving mechanism linear electric motor, linear electric motor and reciprocating pump.Linear electric motor by can (1), up and down end cap (12) spindle iron core (2), three-phase spindle winding (3), hollow mover guide rail (4), damping spring (5), upper-lower position sensor (6), hollow mover iron core (7), mover winding (8), the drive link (9) and the ground controller that are fixed on the mover are formed up and down.When being connected with threephase AC in the three-phase spindle winding, can produce alternating magnetic field in the mover core, produce induction current in the mover coil, induction current is the motion of driver under stress mover in magnetic field, when mover moves to up and down reversing point, position transducer sends the commutation of commutation signal controller control linear electric motor, drives the reciprocating piston pump to-and-fro motion thus crude oil is extracted into ground.As being short of power that single motor produced, can take multistage relay mode.
Below in conjunction with accompanying drawing one case study on implementation is described: 1, spindle iron core (2) is loaded in the spindle shell (1), is lowered to the spindle winding of desiring to make (3); 2, the upper and lower end damping spring is loaded on up and down end cap, the lower end cap that assembles is loaded on the shell, hollow mover guide rail (4) is packed into, the mover of packing into from the upper end, the drive link of packing into from the lower end (9) also is connected with mover, loads onto the upper end cap that assembles; 3, space sealing pipe (11) between linear electric motor and reciprocating pump and reciprocating pump (14) being gone up end housing links to each other, drive link (9) linked to each other with reciprocating pump pull bar (13) again links to each other space sealing pipe (11) between linear electric motor and reciprocating pump, 4, oil pipe is connected with hollow mover guide rail (4): with pump down to the precalculated position.
