Technical field
The present invention relates to a kind of from well the beam-pumping unit of recover petroleum, be specifically related to a kind of magnetic coupling slow-speed motor direct-drive type beam-pumping unit.
Background technology
Beam pumping unit, also claim girder-like oil pump, beam type crank balanced pumping unit, refer to contain walking beam, by linkage, commutate, the oil pumper of crank pouring weight balance, is commonly called as the machine of kowtowing, beam pumping unit, from oil production method, belonging to and have bar class oil production equipment, is oil field one of main oil pumper type of using at present.As shown in Figure 1, traditional beam pumping unit, consists of horse head, walking beam, support, connecting rod, crank, balance weight, control device, base, reduction box and motor.Horse head is connected in one end of walking beam, connecting rod is connected in the other end of walking beam, the top of support is connected in the middle part of walking beam, the bottom of support is fixed on base, the middle part of crank is connected in the end of connecting rod, and balance weight is connected in crank, and motor is connected in reduction box by belt, control device is fixed on base, in order to control the duty of motor.Its operating principle is: take motor as power, utilize belt transmission effect, drive change gear box work, thereby obtain the slow-speed of revolution needing, and drive crank to rotate, by the transformation of connecting rod, walking beam and horse head, drive downhole pump to do rectilinear motion.
Traditional this beam pumping unit, 1), complex structure there are the following problems:: motor, by belt, drives reduction box work, thereby just can obtain the required slow-speed of revolution; 2), poor work stability: wearing and tearing or broken teeth, belt easy fracture easily appear in the gear on reduction box; 3), consume energy high: gear drive and belt transmission all can cause gearing loss; 4), maintenance cost is high: gear drive and belt transmission all can cause gearing loss; For guaranteeing normal use, need the gear oil in periodic replacement belt and reduction box.
Therefore, we need a kind of simple in structure, job stability is high, it is low to consume energy, maintenance cost is low beam pumping unit.
Summary of the invention
The object of the invention is to solve in prior art, beam pumping unit complex structure, poor work stability, the problem that power consumption is high, maintenance cost is high, provide a kind of magnetic coupling slow-speed motor direct-drive type beam-pumping unit.
For achieving the above object, the technical solution adopted in the present invention is as follows:
Magnetic coupling slow-speed motor direct-drive type beam-pumping unit, comprise horse head, walking beam, support, connecting rod, crank, balance weight, control device and base, described horse head is connected in one end of walking beam, described connecting rod is connected in the other end of walking beam, the top of described support is connected in the middle part of walking beam, the middle part of described crank is connected in the end of connecting rod, described balance weight is connected in crank, described control device is fixed on base, it is characterized in that: also comprise magnetic coupling slow-speed motor, the output shaft end of described magnetic coupling slow-speed motor is connected in the end of crank.
Described magnetic coupling slow-speed motor is to adopt magnetic coupling technology to reach the motor of low speed.
Compared with prior art, the invention has the advantages that: the present invention adopts magnetic coupling technology, make magnetic coupling slow-speed motor, met the requirement of the high-power output of low speed.Thereby with magnetic coupling slow-speed motor, replaced traditional motor by belt, driven the combining structure of reduction box work.Not only simplify the structure,, also solved because reduction box and belt cause meanwhile, poor work stability, the problem high, maintenance cost is high consumes energy.Thereby make that structure of the present invention is more simple, job stability is higher, power consumption is lower, maintenance cost is lower.
Accompanying drawing explanation
Fig. 1 is beam pumping unit structural representation in prior art;
Fig. 2 is magnetic coupling slow-speed motor direct-drive type beam-pumping unit structural representation of the present invention.
The specific embodiment
One embodiment of the present invention are exactly in prior art, and as shown in Figure 1, motor 11, by belt 12, drives reduction box 10 work, the improvement that this combining structure is made.Below in conjunction with 2 pairs of one embodiment of the present invention of accompanying drawing, make detailed description.
As shown in Figure 2, magnetic coupling slow-speed motor direct-drive type beam-pumping unit of the present invention, is comprised of horse head 1, walking beam 2, support 3, connecting rod 4, crank 5, balance weight 6, control device 7, base 8 and magnetic coupling slow-speed motor 9.One end of walking beam 2 is connected in horse head 1, and the other end is connected in connecting rod 4.The top movable of support 3 is connected in the middle part of walking beam 2, in order to support walking beam 2.The middle part of crank 5 is movably connected on the end of connecting rod 4, meanwhile, is also provided with balance weight 6 on crank 5.Control device 7 arranges on base 8.Magnetic coupling slow-speed motor 9 is fixed on base 8, and the output shaft end of magnetic coupling slow-speed motor 9, is directly connected in crank 5.Magnetic coupling slow-speed motor 9 comprises the strong magnetic end of rare earth and copper dish.Magnetic coupling slow-speed motor 9 is to adopt magnetic coupling technology to reach the motor of low speed.It utilizes the strong magnetic end of rare earth, during with the relative motion of copper dish, and the huge magnetic force of generation, directly driving crank 5 work.Meanwhile, by frequency conversion control technique, can carry out stepless speed variation to magnetic coupling slow-speed motor 9, thereby make magnetic coupling slow-speed motor 9, keep the state of the required high-power output of low speed.
The present invention adopts magnetic coupling technology, makes the magnetic coupling slow-speed motor 9 can be lasting, keeps the high-power output state of low speed, and speed can remain on 1～10 rev/min.With magnetic coupling slow-speed motor 9, replaced traditionally, motor 11, by belt 12, drives reduction box 10 work, this combining structure.Thereby simplify the structure, saved cost.Meanwhile, also avoided gear drive and belt transmission, the mechanical loss causing, has produced significant energy-saving effect.The service behaviour that it is stable, has guaranteed that beam-pumping unit can stablize lasting work, and has greatly reduced maintenance cost.
