Fig. 3 is a hydraulic schematic diagram of the present invention.
The specific embodiment
A kind of improved automatic control hydraulic drive oil pumping machine, as Fig. 1, Fig. 2, shown in Figure 3, be included in the hydraulic cylinder of installing on the hydraulic circuit and motor-driven reversal valve 7 is being set on hydraulic cylinder 4, the journey controller 10 that install hydraulic cylinder 4 piston rod ends is provided with the stroke of symmetry and regulates block 9, the control arm of motor-driven reversal valve 7 matches with the block 9 of symmetry, on support 1, installing upright hydraulic cylinder 4 and support frame 12, hydraulic cylinder 4 piston rod parts are installed with movable pulley 11, and the sprocket wheel 14 that has safe locking device is installed on support frame 12 upper mounting plates.Safe locking device is a ratchet mechanism, is installing ratchet 22 on sprocket shaft, and the ratchet of installing on support frame 12 upper mounting plates 13 matches with ratchet 22.The preceding platform 17 of jockey sprocket 16 is housed in the articulated front portion, the outside of support frame 12 upper mounting plates, be hinged on the elevating ram 21 on the support 1, its piston rod is hinged by hinged support bar 20 and preceding platform 17, one end of wire rope 8 is connecting the cable regulator 3 that is packed on the support 1, and cable regulator 3 matches with screw on being packed in support 1 for having the leading screw of handle.The other end of wire rope 8 is by the movable pulley 11 of hydraulic cylinder 4 piston rod ends, be connected with tandem-driving bogie 18 bottoms through the fixed pulley 2 on the support 1, the chain 21 that tandem-driving bogie 18 tops connect is connected with polished rod eye 19 with jockey sprocket 16 by the sprocket wheel 14 on support frame 12 upper mounting plates, and polished rod eye 19 is connecting sucker rod.In tandem-driving bogie 18 balancing weight is housed, the roller of tandem-driving bogie 18 both sides or sliding shoes match with the guide rail of setting in the support frame 12.Variable capacity oil pump 6 is installed on hydraulic circuit, on the oil circuit of variable capacity oil pump 6 and hydraulic cylinder 4, set gradually pilot operated directional control valve 26, one-way throttle valve 27, hand-operated direction valve 28, electromagnetic valve 29 and Three-way rotary valve 25, on the import and export oil circuit of hydraulic cylinder 4, connecting elevating ram 21 by Three-way rotary valve 25 respectively.Hydraulic circuit oil connects fuel tanks 30 through pilot operated directional control valve 26, other Three-way rotary valve 25, oil return fine filter 23, on the oil circuit of described other Three-way rotary valve 25 and oil return fine filter 23 forced heat abstractor 24 is being set.In summer, oil return enters fuel tank 30 through pilot operated directional control valve 26, Three-way rotary valve 25, forced heat abstractor 23, rotates Three-way rotary valve 25 in the winter time, and oil return is without forced heat abstractor 24, oil sump tank 30.
Operating principle of the present invention as shown in Figure 3, because action of gravity drops to terminal point, stroke on the Fill argon clamping fixture 10 is regulated block 9 and is pushed into motor-driven reversal valve machine 7 control arms the next when sucker rod.This moment, control oil channel pressure oil entered pilot operated directional control valve 26 left sides through motor-driven reversal valve 7, promoted pilot operated directional control valve 26 spools and moved right.At this moment, pressure oil rises to setting pressure, through pilot operated directional control valve 26, one-way throttle valve 27, hand-operated direction valve 28, electromagnetic valve 29, Three-way rotary valve 25, enters hydraulic cylinder 4 and promotes the piston rod rising.The speed that piston rod rises is to be set up by variable capacity oil pump 6, and the oil of hydraulic cylinder 4 is through hand-operated direction valve 28, pilot operated directional control valve 26, Three-way rotary valve 25, oil return fine filter 23.Process forced heat abstractor 23, oil sump tank 30 during summer; Three-way rotary valve 25 rotates during winter, and oil return is without forced heat abstractor 23, oil sump tank 30.When hydraulic cylinder 4 piston rods rise to the stroke top dead centre, stroke on the Fill argon clamping fixture is regulated block 9, be pushed into motor-driven reversal valve machine 7 control arms upper, motor-driven reversal valve 7 transpositions, this moment, control oil channel pressure oil entered pilot operated directional control valve 26 right sides through motor-driven reversal valve 7, promoted pilot operated directional control valve 26 spools and was moved to the left.Because pilot operated directional control valve 26 spools are " H " type function, so this moment, hydraulic system pressure was in unloading condition, the discharge capacity of variable capacity oil pump 6 through pilot operated directional control valve " H " type function through the oil of Three-way rotary valve 25, forced heat abstractor 24, oil filter 23, oil sump tank 30. hydraulic cylinders 4 because oil is discharged in the effect of gravity, add in the hydraulic cylinder 4 through Three-way rotary valve 25, electromagnetic valve 29, hand-operated direction valve 28, one-way throttle valve 27, pilot operated directional control valve 26 " H " type function loop oil sump tank 30 or by the loop.This moment, one-way throttle valve 27 just can be controlled the decrease speed of hydraulic cylinder 4 piston rods and the realization sucker rod is upper and lower does variable motion.Can realize that for the thin oil oil production technology decrease speed makes oil well pump that a sufficient oil-absorbing process is arranged slowly, the rate of climb is fast, reduces oil well pump and reveals, and can improve output.If during well workover, Three-way rotary valve 25 gone to turn over oil cylinder 21 loops, turn over the oil cylinder piston bar rate of climb in the flow speed control valve control.Hand-operated direction valve 28 major functions on the hydraulic circuit are that piston rod stretches out and losing under the situation of gravity and can't withdraw, and available in this case hand-operated direction valve 28 is finished withdrawal.The major function of electromagnetic valve 29 is: the energising of machine operate as normal, the electric loop of electromagnetic valve 29 is connected the machine power failure or is quit work.Electromagnetic valve 29 dead electricity, electromagnetic valve 29 spring reset hydraulic cylinders 4 rodless cavity oil are blocked.Sucker rod this moment, transfixion that is to say no matter sucker rod is to rise or the decline operating mode, and shutting down sucker rod at any time all can transfixion, can not cause because pump load produces to dash down greater than tandem-driving bogie 18 weight causes the accident, and is safe and reliable.Hydraulic cylinder 4 produces thrust under the effect of system works pressure, promotion is installed in the running block of piston rod end, work stretches out motion, be fixed on wire rope product degree adjuster 3 on around wire rope one end on the movable pulley this moment, wire rope is through the vertical intermediary of running block fixed pulley 5 assembly pulley that reverses again, vertically-guided fixed pulley 2 is connected with tandem-driving bogie 18 bottoms, realized piston rod speed * 4=sucker rod hoisting velocity under the effect of running block, the oil cylinder of 1 meter of stroke just can be realized 4 meters stroke like this.Avoided the piston rod high-speed motion, piston rod movement speed has reached perfect condition, and prolong a lot the application life of oil cylinder.
Not only compact conformation, volume are little, in light weight, power consumption is low in the present invention, reliable operation, fault rate are low, and can regulate stroke and jig frequency easily, the realization sucker rod is done upper and lower variable motion according to the oil production technology needs, has improved the mechanical performance of equipment operation.During well workover, under the situation of mobile host not, can solve the well workover space easily.
