Abstract
A flywheel energy-saving device on a beam pumping unit relates to a mechanical recovery equipment component, which is characterized in that a flywheel is mounted on an input shaft of a reduction gearbox, the flywheel is combined with a brake device, and an overrunning clutch is installed on a belt pulley. The flywheel energy-saving device has the advantages that during oil pumping process, impact damage to a driving mechanism caused by uniform inertial load can be avoided, and energy of the inertial load can be stored to be utilized, thereby achieving the purpose of saving energy. When the rotating speed of the input shaft of the reduction gearbox exceeds a certain rotating speed, the input shaft can be separated from a large belt pulley, thereby preventing increment of the rotating speed of a motor. Besides, the flywheel energy-saving device enables power output of the motor to be more uniform, thereby saving electricity further. The flywheel energy-saving device is simple in structure, reliable in operation and long in service life.
Description
Technical field
The utility model relates to a kind of parts of mechanical oil recovery equip ment in the oilfield exploitation.
Background technology
In the petroleum production engineering of oil field, the plant equipment that adopts is beam pumping unit mostly, and it is a kind of quadric chain, and its suspension point (being commonly called as horse head on oil pumper) drive polished rod and beam hanger foremost is reciprocating, thereby it is reciprocating to drive the oil extraction pump plunger, recovers the oil.But in a reciprocating process, its movement velocity and inertia force are not the relations of simple increasing or decreasing, in upstroke, its preceding half stroke acceleration direction is identical with the direction of motion, be that acceleration makes progress, and inertia force is downward, being increases polished rod load gradually; In its later half stroke, the acceleration direction is opposite with the direction of motion, and promptly acceleration is downward, and inertia force upwards, is to reduce polished rod load gradually.In down stroke, situation is then just opposite, and preceding half stroke acceleration is downward, and inertia force upwards reduces polished rod load gradually; Later half stroke acceleration makes progress, and inertia force is downward, will strengthen polished rod load.Though the difference of polished rod load in upper and lower stroke has obtained solution to a great extent through taking to install additional balance weight, back horse head and other measure, make the oil pumper basically can operate as normal.But, in a stroke, the motion state that acceleration is opposite with the inertia force direction exists all the time, on having caused, in the down stroke, preceding half stroke output power of motor acting, later half stroke is because the effect of inertia force, the inertial load that forms impels the crank rotation to quicken, and passes through reduction box, belt transmission can make the runaway speed running at short notice, its rotating speed can surpass its rated speed, and make motor become generator, but the electric current that sends can not obtain utilization again, can only consume with the form of doing negative work, therefore beam-pumping unit still has quite a few energy to be wasted at present, and the electric work utilization rate also has the space of improving.
The utility model content
The purpose of this utility model is the flying wheel energy saver on a kind of beam-pumping unit of design, uses it further to economize on electricity, and improves capacity usage ratio.
Technical solution of the present utility model is to realize like this, flying wheel energy saver on a kind of beam-pumping unit, at reduction box power shaft left end belt pulley is installed, its right-hand member is equipped with brake wheel, on the reduction box housing, brake gear is installed, its special character is on the reduction box power shaft flying wheel to be installed.
In above-mentioned technical solution, its special character is that also the end that brake wheel is installed at the reduction box power shaft is equipped with flying wheel, and flying wheel and brake wheel combine.
In above-mentioned technical solution, special character also is, freewheel clutch is installed on belt pulley.
The usefulness of this device is: 1. owing to installed flying wheel (flywheel) additional on the power shaft of reduction box, not only can replace motor brake inertial load cause the excessive hypervelocity of transmission mechanism, avoid impact failure to transmission mechanism, but also the energy of inertial load can be stored, and the later half stroke that passes through upper and lower stroke in the crank angle discharges, it is more balanced to make mechanism transmit energy, reaches purpose of energy saving.2. because freewheel clutch is installed on big belt pulley, in oil pumping process, when the power shaft rotating speed of reduction box surpassed its certain rotating speed, the reduction box power shaft can separate with big belt pulley, and motor speed is increased.3. these two technical measures of freewheel clutch and flying wheel will be installed combine, and be assembled in the same transmission system, and can make oil pumper in operation process, power of electric motor output is more steady, can further play power savings.4. the inertia belt sheave structure is simple, reliable operation, long service life.
Description of drawings
Accompanying drawing is cross-sectional view of the present utility model (reduction box does not cut open).
The specific embodiment
On camshaft 8, cam is arranged, camshaft 8 is installed on the dial 9, dial 9 is sleeved on the left end of brake hoop 5, the front end of camshaft 8 is inserted in the hole of shoe plate 7 and brake hoop 5, on shoe plate 7, be fixed with brake block 4, the hoop 5 that will brake is installed on the reduction box housing 2 by screw, and pull bar 10 connects mutually with dial 9, more than forms brake gear.The brake wheel of former oil pumper is thickeied to increase its weight, as flying wheel 3 of the present utility model, make flying wheel and brake wheel in conjunction with as a whole,, join the flying wheel of 420 kilogram weights as the oil pumper of 12 types according to the weight of oil pumper model and oil well depth design flying wheel.Flying wheel 3 is installed in power shaft 6 right-hand members of reduction box 2 by axle key.
When oil pumper turns round, drive sucker rod, the oil well pump piston reciprocates, last, in the down stroke, preceding half stroke output power of motor oil pumping acting, later half stroke is because the effect of inertia force, the inertial load that forms impels the crank rotation to quicken, pass through walking beam, connecting rod, crank is delivered in the clutch, at this moment freewheel clutch will make belt pulley 1 and axle sleeve 14 break away from connection relation, the acceleration that inertial load is produced can not be delivered on the motor, because flying wheel 3 and axle sleeve 14 are installed on the same axle, therefore this energy can be stored on the flying wheel 3, by the time the crank angle is on the pumping unit horsehead, in the later half stroke of down stroke, this energy can be discharged, reach purpose of energy saving.
