Abstract
Disclosed is a cam cylinder automatic control beam-pumping unit which is mainly composed of a motor 1, a speed reducer 2, a brake 3, idle gears 7, a dynamic force cylinder 8, a pylon 6, etc., wherein, a support bracket 5 which is arranged above the pylon 6 is provided with the motor 1, the speed reducer 2, the brake 3, and the dynamic force cylinder 8; the two sides of the radical direction of the dynamic force cylinder 8 are respectively provided with the two same idle gears 7; the two ends of a steel cable 10 which winds around the dynamic force cylinder 8 are respectively connected with a lifting device 4 and a balance block 9 through the gear grooves of the idle gears 7; a shaft coupling is arranged between the brake 3 and the speed reducer 2. The utility model has the advantages of simple structure, stable work, convenient production, convenient maintenance, and a large amount of steel saving.
Description
The utility model belongs to a kind of oil production equipment in the petroleum industry.
In the petroleum industry, oil production method mainly contains two kinds of blowing method and oil pumping methods.The characteristics of blowing method are to utilize the energy on stratum itself to come lifting crude oil.Along with continually developing of oil field, stratum energy consumes gradually, even in the oil field of waterflooding extraction, water logging and strong water logging phenomenon have also appearred in its intermediary and later stages.In order to guarantee the stable and high yields of crude oil, just must exploit with the oil pumping method.Domestic and international application pumping unit the most widely is a beam pumping unit, or is called sucker-rod pumping equipment.Along with the continuous increase of well depth and output, the shortcoming of beam pumping unit is just more obvious, mainly is that pumping unit weight increases, and the accident of sucker rod increases and the pump delivery reduction of pumping aborning.In order to alleviate the weight of pumping unit, adopted no beam pumping unit.Through consulting interrelated data, still find no and the same or analogous record of the utility model.
The purpose of this utility model is in order to alleviate the weight of traditional pumping unit, to increase the oil pumping throw of pump, therefore having designed cammingly cylinder automatic control pumping unit.
The utility model is realized as follows:
Cammingly cylinder automatic control pumping unit, mainly form by motor 1, retarder 2, brake 3, idle pulley 7, power drum 8, pylon 6 etc., support 5 is housed above pylon 6, motor 1, retarder 2, brake 3 and power drum 8 are housed on support 5, be respectively equipped with two identical idle pulleys 7 in the radially both sides of power drum 8, the two ends that are wrapped in the wire rope 10 on the power drum 8 rise device 4 and link to each other with equilibrium block 9 with outstanding via the race of idle pulley 7 respectively, between brake 3 and retarder 2 coupling are housed.The surface of power drum 8 is provided with spirality cam line steel wire rope groove.The wheel rim of two idle pulleys 7 is provided with can receive the race of wire rope.
The utility model has the advantages that: can improve the length of stroke of oil well pump effectively, reduce strokes per minute, improve the working life of sucker rod, simple in structure, easy to operate, performance is safe and reliable, and is in light weight, saves steel.
Fig. 1 is a main TV structure schematic representation of the present utility model;
Fig. 2 is a side-looking structural representation of the present utility model.
Introduce most preferred embodiment of the present utility model with reference to the accompanying drawings in detail:
Cammingly cylinder automatic oil pumping machine, pylon 6 and support 5 all are to be welded with shaped steel, motor 1 usefulness variable-frequency governor control clockwise and anticlockwise is to realize the work of the upper and lower stroke of pumping unit.Motor 1 through retarder 2 with transmission of power to power drum 8, on power drum 8, be fixed with wire rope 10, an end of wire rope 10 is connected with equilibrium block 9, the other end rises device 4 and links to each other with hanging, and hangs to rise device 4 and link to each other with sucker rod in the oil well.During work, motor 1 rotates through retarder 2 transfer motion power cylinders 8, thereby wire rope 10 is driven outstandingly rises device 4 and sucker rod is up moves with the upstroke of finishing the oil well pump piston, when upstroke stops, thereby motor 1 counter-rotating makes the descending realization down stroke motion of sucker rod, owing to be provided with spirality cam line steel wire rope groove in the both sides of power drum 8, when each stroke movement, wire rope twines along the radius roller that changes, but so torque load of checker sucker rod steel wire rope and equilibrium block wire rope.Owing to adopted the cam roller structure, equilibrium block 9 has been stopped reposefully, at the stop of upper and lower stroke so that motor 1 switching direction.The utility model is than simple in structure many of beam pumping unit, and can correspondingly save great deal of steel, and cost of production is relatively low, is convenient to make and safeguard.
Claims (3)
1, cammingly cylinder automatic control pumping unit, mainly form by motor 1, retarder 2, brake 3, idle pulley 7, power drum 8, pylon 6 etc., support 5 is equipped with in the top that it is characterized in that pylon 6, motor 1, retarder 2, brake 3 and power drum 8 are housed on support 5, be respectively equipped with two identical idle pulleys 7 in the radially both sides of power drum 8, the two ends that are wrapped in the wire rope 10 on the power drum 8 rise device 4 and link to each other with equilibrium block 9 with outstanding via the race of idle pulley 7 respectively, between brake 3 and retarder 2 coupling are housed.
