Abstract

The invention provides a motor-direct-driven beam-pumping unit and relates to oil extraction equipment. The motor-direct-driven beam-pumping unit comprises a base, a motor, a frame, a balance weight, a connecting rod, a walking beam and a horsehead; the front end of the base is fixed with the frame; the top end of the frame is in movable fit with and hinged to the middle of the walking beam; the horsehead is fixed at the front end of the walking beam, and a cross beam is fixed at the tail end of the walking beam; the motor is fixed at the tail end of the base, output shafts on the two sides of the motor are in stationary fit with and hinged to one end of the crank arm of the balance weight, and the other end of the crank arm is in movable fit with and hinged to the two ends of the cross arm through the connecting rod. The motor-direct-driven beam-pumping unit is transformed based on a conventional pumping unit, the workload of transformation is low, and the period is short; the number of intermediate gearing-down mechanisms is reduced, so that the transmission efficiency is improved; moreover, vibration during the gearing-down process is eliminated, so that a system runs more smoothly, and the noise is small; the motor is low in rotation speed, low in heat emission and high in efficiency and does not require lubrication; the power factor is increased, reactive loss is reduced, stepless adjustment on the times of stroke is realized, and the service life of the integral beam-pumping unit is prolonged.

Description

Electric-machine directly-driven beam pumping unit
Technical field
The present invention relates to petroleum recovering equipment, relate in particular to a kind of electric-machine directly-driven beam pumping unit.
Background technology
At present, oil pumper has become in oil exploration equipment must indispensable equipment, in numerous oil pumpers, beam pumping unit is a kind of of comparative maturity, it is to utilize motor direction operation, by a series of mechanisms such as Belt Transmission gear reduction units, drive walking beam repeatedly to move, beam pumping unit is from occurring having had so far thousands of optimization to improve, but be all in counterweight, on crank connecting link, improve many, all do not leave the constraint of reductor, there are many shortcomings in this beam pumping unit, as: drive link more, maintenance cost is higher, be unfavorable for adjusting jig frequency, because driving, thereby the more transmission efficiency of link is lower so power consumption is higher, noise is larger simultaneously, gear-box internal construction is complicated, Breakdown Maintenance degree-of-difficulty factor is more high.
Summary of the invention
The present invention is intended to for the deficiency existing in background technology, and a kind of electric-machine directly-driven beam pumping unit is provided, and has cancelled the setting of reduction box, has overturned traditional transmission mode of beam-balanced pumping unit, is that beam pumping unit is optimized an improved revolution.
Electric-machine directly-driven beam pumping unit of the present invention, to be formed by base, motor, frame, balance weight, connecting rod, walking beam and horse head, front end and the frame of base fixed, the moving coordination hinge in frame top and walking beam middle part, and walking beam front end is fixed wtih horse head, tail end is fixed with crossbeam; The output shaft that the tail end of base is fixed wtih motor, its both sides respectively, the other end hinged with both sides crank one end stationary fit by the moving coordination hinge in two ends of connecting rod and crossbeam.
As a further improvement on the present invention, described motor is axial two ends symmetric double output shaft motor.
As a further improvement on the present invention, the output shaft of motor is provided with check mechanism.
As a further improvement on the present invention, the described staircase that is fixed with on wing base after motor.
Electric-machine directly-driven beam pumping unit of the present invention, structure design is novel, in the situation that not changing pumping unit main body structure, directly replaces reduction box, motor and the control cabinet of former oil pumper with motor.Change workload is little, and the cycle is short; Reduced intermediate reduction gear transmission mechanism, improved transmission efficiency, and eliminated the vibration in deceleration transmission process, system operation is more steady, and noise is little; Motor speed is low, generates heat little, and efficiency is high, without lubricated; Improved power factor, reduced reactive loss, and realize jig frequency step-less adjustment; Owing to having cancelled reduction box and conventional motor, reduced replacing reduction box lubrication oil and belt, reduce trouble point, realizes non-maintainingly, improves oil pumper machine life.
