Abstract
The compound wheel type beam-pumping unit belongs to the petroleum oil production mechanism. The compound wheel type beam-pumping unit is composed of a machine frame, a speed reducer, a crank pitman mechanism, a compound wheel lifting device and a balanced system. The compound wheel type beam-pumping unit is characterized in that the compound wheel type beam-pumping unit achieves the long stroke oil production by means of the crank pitman mechanism and the special compound wheel lifting device. When the utility model is in contrast with the existing beam type pumping unit or the existing chain type pumping unit, the utility model has the following advantages: small volume, light weight, simple structure, few power consumption and long stroke, etc advantages. The weight of the compound wheel type beam-pumping unit is 1/3 weight of the beam type pumping unit, the driving stroke can reach 6 to 10 meter, and the utility model is especially adaptable to be used for the oil field whose viscosity of crude is large in China.
Description
Compound wheel oil-pumper belongs to petroleum recovering machinery.
At present, China's application pumping unit more widely is a beam pumping unit, and it is simple in structure, easy to use, but heavy, the beam pumping unit of 6 meters strokes, and complete machine weight reaches about 50 tons, and big energy-consuming.For fear of above-mentioned deficiency, Chinese patent CN 872 16773 drum type pumping unit provide in light weight, and the chain that consumes energy few rotates pumping unit, but this oil pumper structure is complicated, adopts chain drive, maintenance difficult.
It is a kind of simple in structure, easy to maintenance that the purpose of this utility model is to provide, compound wheel oil-pumper in light weight, that power consumption is few utilizes crank-link mechanism and double action wheel lifting appliance to replace the quadric chain of beam pumping unit and the chain drive and the automatic reversing apparatus of drum type pumping unit.
In order to achieve the above object, 1 pair of structure of the present utility model is described in conjunction with the accompanying drawings.
Fig. 1 compound wheel oil-pumper structural representation
Among the figure: 1 motor, 2 V-belts, 3 reducers, 4 cranks, 5 connecting rods, 6 frames, 7 wire rope fixed pulleys, 8 balance cylinders, 9 wire rope, 10 tracks, 11 polished rod eyes, 12 carriages, 13 rollers, 14 double actions wheel holder, 15 double actions wheel.
As shown in Figure 1, compound wheel oil-pumper is by frame, decelerator, and toggle, double action wheel lifting device and balance sysmte form. Double action wheel lifting device is by carriage, and double action is taken turns, the top of frame, and double action wheel shaft and carriage are fastened as a whole, and on the double action wheel shaft rolling bearing are housed, and direct and double action wheel links together. The carriage bottom is connected with the push rod of balance cylinder upper end, and the lower end of balance cylinder is fixed on the ladder-shaped frame of vertical type frame.
On the carriage of double action wheel lifting device roller is housed, carriage can be done along the track that arranges on the frame through roller and move up and down. The double action at carriage top is taken turns its both sides that are configured to bull wheel and is provided with two steamboats, and they are consubstantialities. After fixed pulley is walked around at the two ends of steel cable, be fixed on the outer rim of two steamboats of double action wheel, and after another root steel wire rope walked around the pulley that is fixed on the outer margin of large wheel, two ends were fixed on the polished rod eye simultaneously, polished rod eye links to each other with sucker rod. When the double action wheel moves up and down along track with carriage, be subjected to pining down of steel wire rope to do corresponding rotation.
The balance sysmte of compound wheel oil-pumper; Adopt the gas balance.Be made up of balance cylinder and push rod, the push rod upper end is connected with the carriage bottom, and the lower end is in balance cylinder, and push rod can be done upper and lower motion with carriage.
The frame of compound wheel oil-pumper is a vertical type, divides upper and lower two parts, and top is rectangular frame, and is provided with track, and the bottom is a ladder-shaped frame.
The course of work of the present utility model is as follows:
After the electric motor starting running, drive reducer, reducer output shaft drives two cranks and rotates, on crank drivening rod and carriage are done, following reciprocating motion.When carriage moves on track, move on the push rod of drive balance cylinder, balance cylinder is emitted the energy of depositing.The wheel of double action simultaneously moves up with carriage, and the wire rope of little double action wheel outer rim is fixed on pining down of fixed pulley on the frame, the double action crop rotation is rotated accordingly, double action crop rotation compound motion.Drive sucker rod and move up thereupon because of fixing on wire rope on the big double action wheel, the actual displacement of sucker rod is that the carriage length that moves up is rotated the radian sum with big double action wheel.When carriage moved down, the double action frame length that moves up was rotated the radian sum with big double action wheel.When carriage moved down, the double action wheel pind down down at sucker rod and rotates, and carriage drive balance cylinder push rod with gas compression in the cylinder, stores simultaneously.Finished the upper and lower reciprocating motion that drives oil well pump.
Advantage of the present utility model: compound wheel oil-pumper is simple in structure, and is in light weight, about 12 tons, is 1/3 of beam pumping unit generally, saves great deal of steel.These machine installation and maintenance are convenient, and equilibrium condition is good, save the energy, low cost of manufacture.The work jig frequency is 2-4 time/minute, and stroke 6-10 rice is more suitable to China high viscosity oil oil field.
Embodiment:
Frame adopts A
3Number steel is welded, and other part adopts 35-45 medium carbon steel to make, and the double action wheel can adopt steel-casting.
The major technique standard of compound wheel oil-pumper:
Suspension point maximum load 12-14 ton
Driving stroke 6-10 rice
Jig frequency 2-4 time/minute
Complete machine weight 10-12 ton
Balance mode gas equilibrium air pressure is 3 MPas
Power of motor 30-45 kilowatt
