Abstract
The utility model relates to a reciprocating submersible motor, in particular to a balance device of the reciprocating submersible motor. The balance device mainly comprises a linear motor, a pull rod, a balance plunger, a pull rod, a packer, a plunger pump, a sleeve and a traveling valve, wherein the linear motor is connected with the balance plunger by the pull rod; the balance plunger is connected with the plunger pump by the pull rod; the plunger pump is provided with the traveling valve; and the bottom of the sleeve is provided with the packer which separates balance liquid from well fluid. The balance device of the reciprocating submersible motor has the beneficial effects that when in up-stroking, the balance liquid and the linear motor drive the plunger pump to ascend, and when in down-stroking, the pressure of the balance liquid to the plunger is in balance with the driving force of the linear motor.
Description
One, technical field:
The utility model relates to a kind of reciprocal submersible electric pump, particularly a kind of Equilibrator of reciprocal submersible electric pump.
Two, background technique:
Chinese patent literature 200410050431.5 discloses a kind of numerically controlled reciprocating submersible pump, be that the plunger in linear motor rotor and the oil well pump is joined, utilize the cable transmission electric energy to give linear electric motor, the direct drive plunger formula of electric mover oil well pump is up and down reciprocatingly finished the lifting campaign.Linear electric motor need the liquid on lift ram top during upstroke, the motor acting; And during down stroke, it is descending that the liquid of plunger upper part drives linear electric motor, and motor does not do work.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and a kind of Equilibrator that utilizes liquid to carry out the reciprocal submersible electric pump of balance is provided.
The technical solution of the utility model realizes in the following manner:
The utility model mainly is made up of linear electric motor, pull bar, balance plunger, pull bar, packet, plunger pump, sleeve pipe and traveling valve, linear electric motor are connected with balance plunger by pull bar, balance plunger connects plunger pump by pull bar, the cavity of resorption of balance plunger and sleeve pipe annular distance communicate, plunger pump is provided with traveling valve, and the bottom of described sleeve pipe is provided with packet balance liquid and well liquid are separated.
Above-mentioned balance liquid is a kind of of well liquid, waste water or counterweight liquid.
The beneficial effects of the utility model are: the drive plunger pump is up together for balance liquid and linear electric motor during upstroke, and the pressure of balance liquid coupled columns plug and the driving force of linear electric motor balance each other during down stroke, and be more energy-conservation.
Four, description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
Five, embodiment:
For further disclosing the technical solution of the utility model, elaborate by embodiment below in conjunction with accompanying drawing:
The utility model mainly is made up of linear electric motor 1, pull bar 2, balance plunger 3, pull bar 5, packet 6, plunger pump 7, sleeve pipe 8 and traveling valve 10, linear electric motor 1 connect balance plunger 3 by pull bar 2, balance plunger 3 connects plunger pump 7 by pull bar 5, the cavity of resorption of balance plunger and sleeve pipe 8 annular distances communicate, plunger pump 7 is provided with traveling valve 10, the bottom of described sleeve pipe 8 is provided with packet 6 separates balance liquid 4 and well liquid 9, and above-mentioned balance liquid 4 is a kind of of well liquid, waste water or counterweight liquid.
During upstroke: linear electric motor 1 are up by the plunger that pull bar 2 drives plunger pump 7, and under the effect of balance liquid 4, balance plunger 3 is subjected to a power that makes progress, and balance liquid 4 auxiliary straight line motors 1 drive plunger is up like this.
Down stroke: when linear electric motor were descending, the traveling valve 10 of plunger pump 7 was opened, and this moment, well liquid did not have active force to plunger, but under the effect of balance liquid, balance plunger is subjected to a power that makes progress, the driving force balance of this power and linear electric motor.
