Abstract

The invention discloses a double-well pumping unit driven by one electric motor. The double-well pumping unit comprises a main machine and an auxiliary machine, wherein each of the main machine and the auxiliary machine comprises a walking beam, a main framework, a horsehead, a counterweight and a base; the bottom end of each main framework is fixed on the corresponding base; the fulcrum of each walking beam is hinged to the top end of the corresponding main framework; each mule head is arranged at the front end of the corresponding walking beam; each counterweight is arranged at the tail end of the corresponding walking beam; an electric motor is mounted on the base of the main machine; a reel is mounted on an output shaft of the electric motor; one end of a first steel wire rope and one end of a second steel wire rope are connected to the reel; the other end of the first steel wire rope is connected with the counterweight of the main machine; a fixed pulley is mounted on the base of the auxiliary machine; the other end of the second steel wire rope rounds to the rear part of the fixed pulley to be connected with the counterweight of the auxiliary machine. The double-well beam pumping unit disclosed by the invention has the characteristics that the loads of the pumping unit are balanced by the counterweights at the tail ends of the walking beams of the pumping unit for two wells, so that oil pumping can be performed on two adjacent oil wells at the same time, and the 50% of energy can be saved; after oil pumping for one of the oil wells is stopped, the oil pumping for the other oil well can still be performed. The double-well pumping unit is simple in structure and convenient to maintain.

Description

The twin-well oil-pumping machine driven by a motor
Technical field
The present invention relates to a kind of oil pumper, specifically a kind of mechanical type cylinder twin-well oil-pumping machine driven by a motor, is applicable to cluster wells production.
Background technology
Oil-field oil pumper kind is more, wherein a kind of structure of the oil pumper generally applied is, one section at walking beam is provided with horse head, and dependence motor drives reduction box to drive crank and connecting rod makes walking beam, horse head swings up and down centered by axis, thus drive sucker rod, reach the object of oil exploitation.This oil pumper every a bite oil well must be equipped with a set of power set (motor, reduction box, crank and connecting rod), and investment is large, and take up room large, energy consumption is high.
Summary of the invention
The object of the invention is to provide a kind of twin-well oil-pumping machine driven by a motor, drives the pumping production of adjacent two mouthfuls of oil wells with an oil pumper simultaneously, large with the investment solving prior art existence, takes up room large, the problem that energy consumption is high.
The object of the invention is to realize by the following technical solutions: a kind of twin-well oil-pumping machine driven by a motor, comprise the main frame of a bite oil well and the subsidiary engine of adjacent a bite oil well, this main and auxiliaries respectively comprises walking beam, body frame, horse head, counterweight and base, the bottom of body frame is fixed on base, the fulcrum of walking beam is hinged on the top of body frame, horse head and counterweight is respectively equipped with in the front end of walking beam and tail end, it is characterized in that, the base of described main frame is equipped with motor, the output shaft of this motor is equipped with spool, this spool connects one end of the first wire rope and the second wire rope, the other end of this first wire rope is connected with the counterweight of main frame, the base of described subsidiary engine is equipped with fixed pulley, is connected with the counterweight of subsidiary engine after the other end of this second wire rope walks around this fixed pulley.
Be dismountable structure between the counterweight of the first described wire rope and the two ends of the second wire rope and spool and main frame, subsidiary engine.
The present invention compared with prior art, has following feature:
1, with the load of the balancing weight balanced oil extractor of the walking beam on pumping units tail end of two mouthfuls of oil wells, can be simultaneously
Adjacent two mouthfuls of oil wells are pumped, energy-conservationly reaches 50%; After wherein a bite oil well stops adopting, another mouthful of oil well still can normally work.
2, operating power is more reasonable, reduces the motor maximum current of oil pumper and the difference of minimum current,
Only this just can save a large amount of electric energy.
3, structure is simple, easy to maintenance.

Detailed description of the invention
See Fig. 1, a kind of twin-well oil-pumping machine driven by a motor of the present invention, comprise the host A of a bite oil well and the subsidiary engine B of adjacent a bite oil well, this host A and subsidiary engine B respectively comprise walking beam 5, body frame 7, horse head 6, counterweight 4 and base 8, the bottom of body frame 7 is fixed on base 8, the fulcrum of walking beam 5 is hinged on the top of body frame 7, horse head 6 and counterweight 4 is respectively equipped with in the front end of walking beam 5 and tail end, it is characterized in that, the base 8 of described host A is equipped with motor 1, the output shaft of this motor 1 is equipped with spool 9, this spool 9 connects one end of the first wire rope 2 and the second wire rope 10, the other end of this first wire rope 2 is connected with the counterweight 4 of host A, the base 8 of described subsidiary engine B is equipped with fixed pulley 3, and the other end of this second wire rope 10 is walked around this fixed pulley 3 and is connected with the counterweight 4 of subsidiary engine B afterwards.
Be dismountable structure between the counterweight 4 of the first described wire rope 2 and the two ends of the second wire rope 10 and spool 9 and main frame, subsidiary engine, when only needing an oil well job, the first wire rope 2 or the second wire rope 10 of can dismantling.
When oil pumper has been in place the counterweight 4 of later adjustment oil pumper afterbody, the load of the weight ratio well rod of oil pumper afterbody is made to want about one ton.
When host A and subsidiary engine B work simultaneously, by the rotation of the positive and negative both direction of motor 1, make the host A on two mouthfuls of oil wells and subsidiary engine B mono-rising, another declines, and motion reaches simultaneously to the object that two mouthfuls of oil wells recover the oil and so forth.
When side oil well stops adopting and another mouthful of oil well still needs work, after so adjusting the weight of counterweight 4, the first wire rope 2 or the second wire rope 10 of then dismantling.Actuating motor 1 drives host A or subsidiary engine B to work by the first wire rope 2 or the second wire rope 10.
