Description
Technical field
The utility model relates to the used plant equipment of oil exploitation, and particularly a kind of variable speed energy conservation power set that are applicable to oil pumper belong to the new type power energy saver that oil well extracts crude oil.
Background technology
In the exploitation of oil, oil pumper at present commonly used is by quadric chain rotatablely moving of motor to be become the reciprocating motion of oil well pump, makes oil production machine finish the oil pumping function.This oil pumper is a cycling alternating load, when upstroke, horse head drives oil pump and pumps, and machine is made useful work, and this moment, the horse head of oil pumper bore the liquid emphasis amount that acts on piston cross-section and sucker rod weight and the loads such as friction, inertia, vibration in liquid is annotated; And horse head is when descending (oil pump oil suction), and machine is made idle work, and this moment, the horse head of oil pumper only bore the weight of sucker rod in liquid is annotated.In the course of the work, useful work and idle work slightly account for half in time, and the load difference of up-down stroke is very big, the high-power high pulling torque work of upstroke motor, and down stroke is unloaded, power dissipation.So currently used driving arrangement all is high power motor usually, power consumption is high, and power factor is low.The energy consumption that how to reduce this oil production equipment has become the technical task that relevant insider seeks.
Summary of the invention
A kind of output torque that the purpose of this utility model is designed at above-mentioned existing in prior technology defective just can be with the variable speed energy conservation power set that are applicable to oil pumper of rotation speed change, low, the high efficiency of this power set energy consumption can make the oil pumper installed power reduce by 50% and save electricity more than 30%.
The purpose of this utility model realizes by following scheme: the variable speed energy conservation power set that originally are applicable to oil pumper comprise initiatively motor and by motor-driven pump load initiatively, wherein, between active motor and pump load, be provided with and help speed motor, initiatively motor shaft is connected with helping the speed motor axle with gear by one-way clutch, helps the speed motor axle to be connected with load.
In the utility model, speed change gear can be following scheme: promptly gear comprises and is sleeved on the motor shaft initiatively and sun gear, the planetary gear that is meshed with sun gear that match with one-way clutch on being installed in motor shaft initiatively and be fixedly connected on the planet carrier composition that helps on the speed motor axle.This moment initiatively motor shaft with help the speed motor axle to be the coaxial line mode to be provided with.
Speed change gear also can be another kind of scheme: promptly gear comprise be sleeved on help on the speed motor axle and be installed in the gear wheel that helps the one-way clutch on the speed motor axle to match, be installed on the motor shaft initiatively and form with the gear wheel pinion in mesh.This moment initiatively motor shaft with help the speed motor axle to be the parallel mode setting.
Operation principle of the present utility model is, adopts the principle of inertia of mechanics uniformly accelerated motion, thereby makes oil pumper reach desirable result of use in conjunction with prior art.In use, pass to by gear earlier and help speed motor output slow-speed of revolution power,, rotate by helping speed motor to drive load when load speed is lower than when helping speed motor (rated speed) by the active motor, one-way clutch breaks away from simultaneously, helps speed motor output to be accelerated motion.That is to say, when the active motor rises to most significant end to the oil pumper upstroke by gear, descending rapidly fully is discharged in the next upstroke kinetic energy in the down stroke by helping speed motor to drive load (this moment, clutch broke away from), dash to most significant end by the load of active driven by motor again, so go round and begin again, can make the active motor and help speed motor alternation in different speed, the actuating unit gross power is descended one times, energy-conservation more than 30%, realize the kinetic energy characteristic of small-power, high pulling torque, solved the high defective of existing oil pumper power consumption.
Advantage of the present utility model is: owing to increased gear and one-way clutch, can make the active motor and help speed motor alternation in different speed, realize that output torque can reduce energy consumption with rotation speed change, has improved operating efficiency.
