The prior art beam pumping unit is in order to satisfy the starting of oil pumper, the power of selected gas-distributing motor is all much bigger than power demand in the oil pumper real-world operation process, add the minimizing of oil content in the oil well, the power that motor is exported in actual use is far longer than the required power of oil pumper actual motion.Common " low load with strong power phenomenon " that Here it is.In order to solve this technical problem, the utility model adopts multispeed electric machine to mate the pre-retarding device of high transmission efficiency, the starting of employing low speed, the working method of high-speed cruising: both satisfied the required power of system's starting, and can satisfy power required in the running again.Not only reduced the loss of motor self, and made motor, improved the gross efficiency of motor all the time in high efficient area work.
The freewheel clutch of the utility model makes the energy in the system directly store, and discharges automatically subsequently, and is both energy-conservation thus, and asynchronous generating is to the interference of electrical network when having avoided the hypervelocity rotation again.Detailed process is as follows:
When crankshaft balance weight 61 when the summit begins to fall, because its potential energy of effect of gravity is converted into kinetic energy, the load of motor 10 begins progressively to alleviate, when the action of gravity of described crankshaft balance weight 60 makes main shaft 51 rotary speeies of described reducing gear 50 surpass the rotating speed of motor 10 driving big belt pulleys 30, this moment pre-retarding device 15 be subjected to force direction opposite with the locking direction of freewheel clutch, freewheel clutch promptly is released or breaks away from connection, thereby makes motor 10 almost no-load running and power saving.
When crankshaft balance weight 61 falls to minimum point, its kinetic energy begins to be converted into potential energy and stores, under the effect of gravity, main shaft 51 rotating speeds of described reducing gear 50 are slack-off gradually, until consistent with the rotating speed of big belt pulley 30, in the still approximate no-load running of this stage motor 10, still for saving the time period of electric energy, this moment pre-retarding device 15 be subjected to force direction identical with the locking direction of freewheel clutch, freewheel clutch promptly is fixed or connects, and motor 10 beginning load runnings are transmitted the drawing force of motor to reducing gear 50 by big belt pulley 30, until described crankshaft balance weight 61 is promoted to the summit, a complete cycle of described oil recovery finishes.
The utility model freewheel clutch 12 is to select according to the torque of pre-retarding device 15, and is installed in small belt pulley 11 the insides on these pre-retarding device 15 output shafts.Freewheel clutch 12 with the difference of other clutches is, it need not controlling organization, but rely on its unidirectional locking principle to realize connecting or the disengaging effect, the transmission of its moment is unidirectional, promptly between driving shaft and driven shaft, can only make driven shaft do a direction rotation, have the idle running function in the time of in the other direction.The connection of the utility model freewheel clutch 12 or disengaging are determined by the force direction that is subjected to that is attached thereto the pre-retarding device 15 that connects fully, when the locking direction that is subjected to force direction and freewheel clutch 12 of this pre-retarding device 15 was identical, freewheel clutch 12 promptly was connected; When the locking direction that is subjected to force direction and freewheel clutch 12 of pre-retarding device 15 was opposite, freewheel clutch 12 was promptly thrown off.The utility model freewheel clutch 12 can surmount or transmitting torque, accurately locate, prevent to reverse.Because be prior art, no longer superfluous herein chatting.
The utility model oil pumper is mainly by the research change torque operating mode of beam pumping unit in operation process, and each moving component such as crankshaft balance weight and mule-head hanger and oil well pump and be extracted the weight of crude oil of lifting and their traffic direction and position all can make the operating mode of oil pumper real time altering.Rationally and made full use of each moving component of oil pumper especially horse head and the potential energy of crankshaft balance weight and the mutual conversion between the kinetic energy, improve greatly and save the electric energy effect, the while has been avoided the counter productive that rotatablely moves and react to motor and produce of moving up and down of horse head and crankshaft balance weight effectively.
Weight with respect to crankshaft balance weight and horse head, polished rod eye and oil well pump and to be extracted the weight of crude oil of lifting light, be convenient to understand for making problem reduction, the utility model oil pumper is when considering to make full use of the storage between " potential energy-kinetic energy-potential energy " of each moving component of beam pumping unit and transforming, only consider that the pre-retarding device of crankshaft balance weight and horse head and oil pumper is as an integrated load, its combination weight and traffic direction thereof and position, and ignore other parts such as polished rod eye and oil well pump and be extracted the influence of the former weight of oil of lifting to the energy conversion.
The above embodiment has only been expressed preferred implementation of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim; Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model; Therefore, all equivalents and modifications of being done with the utility model claim scope all should belong to the covering scope of the utility model claim.
