The oil pumping machine of the present invention adopts an electromechanical integration structure, has the advantages of improving the service life and the running speed of the complete machine, small volume, light weight, steel saving by 1/3 to 1/2, and electricity saving by 30 to 50%, and is an ideal model.
Description
The invention belongs to driving mechanism and be positioned at the pumping unit of ground and special-purpose oil field oil recovery usefulness, a kind of program-controlled reciprocating beam-pumping unit of more specifically saying so.
Pumping unit is the capital equipment in the recover petroleum, and the pumping unit of each oil field use generally is beam pumping unit or some follow-on beam pumping units both at home and abroad at present.Beam pumping unit is to adopt connecting rod as the power-converting link, its conversion transfer curve near sinusoidal curve, effective merit in an acting cycle
The electromechanical conversion efficiency that is crank-connecting rod only is 63.7%, beam pumping unit adopts the rotation smooth fashion of crank weight, and load is to pump, therefore the load balance degree can not be higher than 64% theoretically, add that secondary balancing can not be higher than 75% yet, and the effect of bearing bigger pulsation moment of torsion as the speed reducer of power and the main transmission link of power, the on-the-spot more serious accident that often takes place of using; Because beam pumping unit adopts connecting rod, therefore it almost is impossible increasing more than the stroke to 7 meter, in whole upper and lower stroke, there is alternate load, sucker rod and even whole pumping unit are all caused fatigue damage, and beam-pumping unit also can't realize the operation of big stroke, little jig frequency, is disadvantageous to improving tar productivity therefore; This in addition pumping unit equipment is big, the energy consumption height, and manufacture cost is also than higher.
In order to improve the problem that the beam pumping unit structure exists, develop more non-beam beam-pumping unit both at home and abroad.For example the patent No. is 90208605.7,92219276.6,93218032.9,93230853.8 disclosed chain type oil pumps, adopt chain as power transmitting elements, the raising of the inefficacy of chain and polygon effect restriction transport velocity, and the life-span of chain report according to interrelated data, only be 15000 hours.
The objective of the invention is to overcome some shortcomings of prior art, developed a kind of efficient energy-saving that has, the program-controlled reciprocating beam-pumping unit of reliable and application electric technology.
Realize purpose main technical schemes of the present invention: the structural type that adopts the electromechanical integration of forming by gear transmission and the control of speed governing commutation electric power.Concrete structure and know-why: the voltage and the control signal supply of exporting certain frequency by the speed governing commutation electric control box that can set stroke and jig frequency reference value are attached thereto motor and the braking device that connects, the rotation of motor is passed to the speed reducer input end through the V-type grouped belt, and four wheel and rack tracks installing on two output shafts of speed reducer are realized the conjugation engagement.Under the control of speed governing commutation electric control box, the actuation gear and the rack-track engagement driving up and down reciprocatingly that be installed in that motor on the reversing gear bracket just changes, counter-rotating and steady commutation just drive speed reducer, thereby drive reversing gear bracket straight line motion up and down reciprocatingly, the stroke that pumps can be adjusted arbitrarily in 1-12 rice, therefore reversing gear bracket links to each other with the down-hole oil rig by the suspension oil well load band that is attached thereto and stride across the overhead traveling crane upper saw pulley, also drives the downhole pump motion of up and down reciprocatingly pumping thereupon.
Described speed governing commutation control box be adopt use on the elevator comprise the line construction of the trade mark as the speed governing commutation control panel of PWP/VVVQ18-37P, it is to adjust motor speed to change frequency of supply, voltage swing and phase place, changes that motor turns to, no surge start and noninertia brake.
Described rack-track adopts the multistage tooth bar structural type of joining, and this form is easily installed, and easy care is easily realized the stroke more than 12 meters, and jig frequency linear velocity maximum can reach more than 10 meter per seconds.
Major advantage of the present invention:
1, owing to adopts gear transmission technology, make full use of that gear transmission is accurate high, velocity range is wide, durable in use and the characteristics of low cost of manufacture, makes machine life long, operate steadily, most of stroke that pumps all is a uniform motion in a straight line, and dynamic load is 0.
2, owing to adopt the no surge start and the noninertia brake of speed governing commutation electric control box control motor, make reversing gear bracket pump just as taking the steady of elevator, eliminate sucker rod, oil well pump alternation fatigue damage, also prolonged the working life of entire equipment.
3, adopt accurate counterweight balance mode, balancing weight is set, power units such as the motor in the pumping unit, speed reducer reach more than 97% the degree of balance also all as the balancer weight of load.
4, mainly by the overall size decision of speed reducer, the complete machine external frame can be accomplished 1.5 square metres of floor spaces to complete machine external dimension of the present invention, because machine volume is little, in light weight, therefore can save steel 1/3-1/2.
5, speed reducer output driven gear radius of the present invention only is the 1/10-1/7 of beam type oil pumping machine crank length, and load balance degree raising 30%, therefore the speed reducer Peak torque is reduced more than 10 times, and it is minimum to pulse.
6, the present invention is owing to adopt the electromechanical integrated structure form, and it is all very steady to start, brake, and the transmission component friction pair is few, and the speed reducer moment of torsion is little, and degree of balance height makes the electric motor power of motor and copper, iron loss all reduce, and system saving electricity reaches 30-50%.
7, the present invention can regulate the reference value of stroke and jig frequency arbitrarily owing to adopt electronic technology in maximum magnitude, and the oil field tar productivity is highly beneficial for improving, and adopts pumping production rate of the present invention can improve 30-50%.
