Abstract
The utility model relates to a long-stroke oil pumping unit, which operates according to the principle of an elevator. The long-stroke oil pumping unit is characterized in that one end of a drag rope is connected to an oil pump and the other end of the drag rope is connected to a counterweight; mutually relative motion makes the loads of a pulling motor equalize to change the direction of a magnetic field, so the motor can make reversing operation. The utility model has the advantages of a simple and economic reversible control system, the simple structure of a bracket, reliable running, convenient maintenance, obvious energy saving effect, and low cost.
Description
The utility model is a kind of long stroke oil recovery pumping unit.
At present at a large amount of beam pumping units that use, be curved arm rod mechanism because it adopts, stroke is short, and power is unbalanced, and volume is big, and efficient is low.Though some improvement project still has many deficiencys at present.Improved from the dragging motor aspect have various high-slip motors, for example a tubular type cage type asynchronous motor.When pump oil pumping heavy duty, motor speed descends, and motor speed raises during pump strike the oil underloading.This motor slip ratio height has strengthened slip loss, but the motor working current ratio is steady, and the loss of motor and power supply network is reduced, and can receive certain energy-saving effect.Improved from the driving mechanism aspect have various long stroke pumping units, for example a long stroke beam-pumping unit with chain without sliding beam.This pumping unit has machine operation more steady, improvements such as the few and stroke longer of inertia loading, but exist mechanism complicated, adjusting stroke and jig frequency inconvenience.Stroke further strengthen deficiency such as have any problem (CN2071846V, CN87103481A).
It is simple that the purpose of this utility model provides a kind of supporting structure, reliable, energy-conservation direct current ladder type pumping unit.
The utility model realizes that as follows accompanying drawing is the structural representation of this Elevator pumping unit, and 1. motors and speed reducer among the figure are 2. taken out same pump, 3. support, 4. counterweight, 5. tow rope, 6.7. guide wheel.Pumping unit is the principle work of adopting elevator.Support, motor and speed reducer are contained in the ground of working site.Upper saw pulley is contained in the two ends, the left and right sides of cantilever tip, and tow rope connects counterweight by motor and speed reducer one end through a upper saw pulley, and the other end connects the oil pump bar by another upper saw pulley.The motor of reversible operation moves up and down through tow rope drive oil well pump and counterweight.When the oil pump bar is upwards proposed oily work done, the counterweight storage potential energy that moves upward.This pumping unit supporting structure is simple, and support height increases maximum stroke length and just can extend, and matches with speed-adjustable motor, is easy to realize long stroke, and Shaochong is inferior, makes the pump topping up full, and it is big to reach discharge capacity, the purpose that loss is few.
Motor adopts brush or brushless direct current motor, and this motor has exciting winding.Owing to be long stroke, do not require that motor is reversible fast, can adopt the reversible scheme in magnetic field.Promptly change armature supply and make the electrical motor gearshift running, change magnetic direction with reversible rectifying device and make the motor forward and backward with a cover speed stream device.The excitation of motor is only set up motor-field, and output mechanical work institute energy requirement is not provided.So the exciting power of motor is little, is (5～10) % of capacity motor approximately.
The direct current ladder type pumping unit that the utility model provides, supporting structure is simple, and is reliable, and operation and maintenance is convenient, and energy-saving effect is remarkable.
