Description
Technical field
The utility model relates to a kind of dynamical system that is used for oil-field oil pumper, particularly a kind of uninterruptible power system of oil-field oil pumper.
Background technology
The power of oil-field oil pumper is normally provided respectively by motor or motor; Under condition with the supply of power electricity; Most motor that adopt drive oil pumper work through reductor, in the remote districts that do not have supply of electric power, then adopt motor to pass through reductor and drive oil pumper work.Yet, in oil pumping process, all can there be associated gas to produce, the tolerance size of this associated gas is unstable, is current few for a long time phenomenon.For avoiding associated gas that surrounding enviroment are polluted, therefore, most associated gases all are that the mode through direct burning consumes.But the burning associated gas not only causes energy waste, also causes air environmental pollution simultaneously.For this reason, can collect the back comprehensive utilization to it.But if the associated gas of each oil well is collected through pipeline, because the associated gas total amount is less, and the dispersion of oil well position, this concentrated comprehensive utilization mode need dispose a large amount of conveyance conduits and ancillary facility, and it is less economical.
Summary of the invention
The purpose of the utility model is exactly the deficiency to prior art; A kind of uninterruptible power system that is used for oil-field oil pumper is provided, and it provides power as the complementary energy to oil pumper with electric energy and associated gas, eliminates environment pollution hidden danger; And the associated gas utilization is abundant, good economy performance.
For realizing above-mentioned purpose, first technical scheme that the utility model adopts.
A kind of uninterruptible power system of oil-field oil pumper; Comprise the oil pumper, the motor that are connected with reductor; The reductor input is connected with the output shaft of motor, and the terminals of motor often are connected with electrical source of power, comprises that also associated gas capable of using is the gas engine of fuel; Gas engine is rotated through the motor shaft that belt transmission drives motor, is connected with isolator between gas engine output shaft and the drive pulley on it.
Adopt the utility model of such scheme; Because electrical source of power often is connected with the terminals of motor; Naturally formed replenishing to power that gas engine provides; When the gas engine fuel abundance and during operate as normal, gas engine provides kinetic energy to the output shaft of motor, motor does not consume or the power of few consumption of power power supply.In the fuel abundance of gas engine and during operate as normal, gas engine independently drives motor output shaft and rotates, and at this moment, though the terminals of motor are connected on the electrical source of power, does not ask for electric energy from power supply, motor is in relative idling conditions.When gas engine causes power output deficiency because of fuel shortage or quits work, motor is replenished or all power supplies by the electrical source of power free of discontinuities automatically, makes its output shaft maintenance set rotational speed, thereby drives reductor and oil pumper work.At this moment, owing to be provided with isolator between the output shaft of gas engine and the belt pulley, the rotational motion of motor output shaft can not drive the rotation of gas engine output shaft.Like this, not only make full use of the associated gas that recovers the oil and produced nearby, practiced thrift power consumption, and eliminated because of associated gas burns in atmosphere and caused the hidden danger of environment pollution, had higher economic value.
Optimized technical scheme; The air inlet front end of said gas engine is provided with the gas balance mixing arrangement; Associated gas passes through the gas balance mixing arrangement to the gas engine air feed; When fluctuating within the specific limits, can keep power basicly stable to the steady air feed of gas engine to be implemented in the associated gas generation.
Another technical scheme that the utility model adopts is; A kind of uninterruptible power system of oil-field oil pumper comprises the oil pumper, the motor that are connected with reductor, and the reductor input is connected with the output shaft of motor; The terminals of motor often are connected with electrical source of power; Comprise that also associated gas capable of using is the gas engine of fuel, gas engine is connected with first motor that is used to generate electricity, is provided with isolator between the output shaft of gas engine and the belt pulley; The output shaft of gas engine is connected with the motor shaft of first motor through isolator, and the gas engine and first motor constitute gas electricity generator; The parallelly connected access of the output power of gas electricity generator motor with electrical source of power; Said motor can be many, and oil pumper is corresponding one by one with the quantity of motor.
Adopt the utility model of this technical scheme; In the fuel abundance of gas engine and during operate as normal, the motor shaft that gas engine drives first motor rotates, first motor speed is slightly larger than its rated speed; First motor is in the generating duty; Its electric energy that sends is incorporated motor into the power electricity, when its electric energy is enough to guarantee the required electric energy of motor, though the terminals of motor are connected on the electrical source of power; But do not ask for electric energy from external electrical source of power; Even in self power generation that gas electricity generator produced during greater than the required electric energy of motor, self power generation also can form compensation to the transportation tail of power electricity, with the line loss of automatic compensation power electricity.When gas engine causes power output deficiency because of fuel shortage or quits work; Motor is replenished or all power supplies by the electrical source of power free of discontinuities automatically; Make its output shaft keep setting rotating speed and drive the rotation of reductor power shaft, and then make oil pumper continue operate as normal.When the output speed of gas engine is not enough to keep the required rotating speed of first motor generating duty; First motor converts the motor duty automatically gradually to; At this moment, because the output shaft of gas engine is provided with isolator, the output shaft that first motor output shaft can not drive gas engine rotates; First motor is in the no-load running state, and electrical loss is extremely low.Since the electric forming that power electricity and gas electricity generator send complementation; Its another benefit of bringing is; A gas engine can provide power for many oil pumpers simultaneously with a gas engine that combines to constitute of one first motor, the same gas engine of associated gas centralizedly supply that the corresponding oil well of each motor produces.Can further make full use of associated gas and good economy performance.
Optimized technical scheme, said first motor is an excitation type motor, utilizes the excitation effect of electrical source of power, can the generating efficiency of gas electricity generator be increased to about 75% by 25%.
Optimized technical scheme; The air inlet front end of said gas engine is provided with the gas balance mixing arrangement; Associated gas passes through the gas balance mixing arrangement to the gas engine air feed; When fluctuating within the specific limits, can keep power basicly stable to the steady air feed of gas engine to be implemented in the associated gas generation.
The utility model beneficial effect compared with prior art is, to oil pumper power is provided as the complementary energy with electric energy and associated gas, eliminate environment pollution hidden danger, and the associated gas utilization is abundant, good economy performance; When associated gas being converted to electric energy output, the generating efficiency of its gas electricity generator can reach about 75%.
