Abstract
The utility model discloses an improvement to oil recovery machinery. The device consists of a reducer, a crankshaft, a connecting rod, a guide rail, a guide pulley, a main pulley and a balance cylinder assembly, wherein the guide pulley and the main pulley are arranged on the same shaft, one end of a steel wire rope arranged in a groove at the outer edge of the main pulley is fixed on the crankshaft, and the other end of the steel wire rope is connected with a sucker rod. The utility model discloses simple structure, weight 11-15 tons, safe and reliable, easy maintenance, balanced energy-conserving effectual.
Description
The utility model is the improvement to petroleum recovering machinery.
At present, the long stroke pumping unit of domestic production and development, all there are shortcomings such as poor reliability, maintenance complexity as chain type oil pump, gear long stroke pumping unit of stroke length increasing etc., Chinese patent CN89205502.2 compound wheel oil-pumper, though weight is lighter, diameter of pulley is excessive, the balanced energy conservation effect is relatively poor, steamboat wire rope bearing load is heavy, and the life-span is short, has increased maintenance work.
For fear of above-mentioned weak point, the purpose of this utility model is to provide a kind of simple in structure, in light weight, reliable operation, balanced energy conservation crankshaft roller formula long stroke pumping unit effective, easy to maintenance.
In order to achieve the above object, in conjunction with the accompanying drawings the utility model structure is described.
Fig. 1: crankshaft roller formula long stroke pumping unit structural representation.
Among the figure: 1 motor, 2 driving-belts, 3 reducers, 4 bent axles, 5 connecting rods, 6 leading blocks, 7 head pulleys, 8 guide rails, 9 wire rope, 10 piston rods, 11 balance cylinders, 12 gas bags.
The decelerator of crankshaft pulley type long stroke oil pump, balance cylinder assembly, guide rail all are fixed on the support, leading block pumps along guide rail, the reducer power output shaft is equipped with bent axle, connecting rod one end is connected with bent axle, the other end is connected with the leading block pivot hinge, and leading block and head pulley are connected on the same axle, and head pulley outer rim groove is equipped with steel wire rope, the steel wire rope two ends are connected with the bent axle other end and sucker rod respectively, and the push rod of balance cylinder piston and leading block axle are hinged.
The utility model course of work is as follows: the driven by motor reducer gear rotates, the driving crank rotation, and bent axle rotates and through connecting rod leading block and head pulley is pumped thereupon. Steel wire rope one end that is contained in the head pulley outer rim groove is fixed on the bent axle, when head pulley moves up, drive sucker rod by steel wire rope and move up thereupon, steel wire rope is dragged next segment distance by bent axle again simultaneously, sucker rod is finished compound motion, has realized the work of oil pumper long stroke. Crankshaft two end connects respectively connecting rod and steel wire rope, regulates when suitable when cylinder balancing pressure, and connecting rod all is subjected to pulling force when up-down stroke, and the power that this pulling force and steel wire rope bear is able to partial equilibrium to the formed moment in crank up center, reaches better energy-saving effect.
Advantage of the present utility model: simple in structure, in light weight, balanced energy conservation is effective, and is sturdy reliable, easy to maintenance, realized long stroke, low jig frequency.
Embodiment:
The utility model can be produced the oil pumper weight of all size size at the 11-15 ton, and jig frequency is 3,4,5 times/minute.
1,5 meters head pulley diameters of 12 tons of length of connecting rod of 6 meters polished rod loads of 1 meter stroke of crank throw are 1.5 meters
2,5.5 meters head pulley diameters of 13 tons of length of connecting rod of 7 meters polished rod loads of 1.2 meters strokes of crank throw are 1.5 meters
3,6 meters head pulley diameters of 14 tons of length of connecting rod of 9 meters polished rod loads of 1.5 meters strokes of crank throw are 1.7 meters
Claims (2)
