Upper signalling means 19, upper signalling means 21, pulley 17 and electric power controller 20 are fixed on the support 18, and support 18 then is installed on the support 1.
Five, the specific embodiment:
Starting at the beginning of operating principle is divided, down stroke and three step summaries of upstroke:
Starting just: this moment, each parts of oil pumper all remained static, and position polished rod eye 22 is positioned at bottom (bottom dead centre).When pressing starting button, electric power controller 20 gives motor 2 energisings, motor 2 starting under no loads.After motor 2 startings, electric power controller 20 begins to electromagnetic clutch 8 input control electric currents.The control electric current of input is in the process of changing from small to big, and the rotating speed of electromagnetic clutch 8 output shafts is promptly from the zero rated speed that increases to motor 2 gradually, and output torque.Drive capstan winch 15 rotations by reducer 13, make steel wire twine and the 23 up actings of lifting sucker rod.This moment is because the rotating speed of the star-wheel 24 of freewheel clutch 3 and freewheel clutch 11 all is ahead of foreign steamer 25, so two freewheel clutches all are in slipping state.This moment, flywheel 9 did not rotate, and still remained static, and did not influence motor 2 actings.
The down stroke stage: when position polished rod eye 22 rose to upper signalling means 19 positions, upper signalling means 19 promptly sent control signal, began to reduce the control electric current of electromagnetic clutch 8.Along with reducing of control electric current, the output shaft rotating speed of electromagnetic clutch 8 is reduced to zero gradually, and sucker rod 23 arrives top dead-centres at this moment.Because this moment, the control electric current of electromagnetic clutch 8 was zero, its output shaft has been free shape, so that sucker rod 23 begin under action of gravity is descending, this moment, motor 2 was in Light Condition, and motor 2 controllers are at this moment with its outage.
Make capstan winch 15 counter-rotatings by position polished rod eye 22, wire rope 16, pulley 17 when sucker rod 23 is descending, drive the output counter-rotating of reducer 13 and electromagnetic clutch 8 then.Its counter-rotating will make the star-wheel 24 and foreign steamer 25 switched in opposite of freewheel clutch 11, thus two-wheeled in conjunction with and force flywheel 9 rotations (counter-rotating).In the descending process of sucker rod 23, its speed constantly increases, the also corresponding increase of the rotating speed of flywheel 9.
After flywheel 9 rotations are got up, the ring gear 7 that install its inner chamber bottom is by the engagement of transition gear 5 with external gear 4, transmission of power is given the foreign steamer 25 of freewheel clutch 3, this moment, freewheel clutch foreign steamer 25 will rotate synchronously and direction is positive veer because the effect of external gear 4 and transition gear 5 will turn to change.Because motor 2 its rotor speeds of outage back constantly reduce, when the star-wheel 24 of the freewheel clutch 3 of rotation was reduced to the rotating speed that is lower than foreign steamer 25 gradually synchronously with it, the two-wheeled combination forced motor 2 rotor speeds no longer to reduce.Though so just make motor 2 cut off the power supply, its rotor still is being in (see figure 3) under the high speed rotation status under the effect of flywheel 9.
The upstroke stage: when position polished rod eye 22 arrived upper signalling means 21 positions, upper signalling means 21 sent signal to electric power controller 20.Electric power controller 20 gives motor 2 energisings immediately, because motor 2 rotors have been in the high speed rotation status and have been unloaded at this moment, only is the exciting curent of motor 2 so give the electric current of motor 2 inputs this moment.Exciting curent only is about 5% of motor 2 rated current, thus can be to motor 2 or miscellaneous equipment or electrical network generation impact, and motor 2 is starting very stably.After motor 2 startings, electric power controller 20 begins to electromagnetic clutch 8 input control electric currents, the ascending level and smooth increase of electric current.Because this moment, the output shaft of electromagnetic clutch 8 was in inverted status, so can making it trend towards change, the input of electric current turns to (brake effect), cause the transition of just changeing by counter steer.
Have inertia mechanical energy during flywheel 9 rotations, mainly show on the rotating speed.When motor 2 starting drive just load, because this moment, flywheel 9 rotating speeds were higher, the foreign steamer 25 of freewheel clutch 3 turns round for driving wheel drives star-wheel 24, so motor 2 is played the power-assist effect.When flywheel 9 through after a while energy consumption, when causing rotating speed to descend, can cause foreign steamer 25 rotating speeds of freewheel clutch 3 to lag behind the rotating speed of star-wheel 24.When being in this state following time, the star-wheel 24 of freewheel clutch 3 and foreign steamer 25 can skid and break away from.This moment, flywheel 9 will withdraw from working system automatically, and can not become the load of motor 2.
When position polished rod eye 22 rose to upper signalling means 19 positions, upper signalling means 19 sent signal, began to control the electric power control that electric power controller 20 carries out down stroke.Go round and begin again.
