Description
Technical field
The utility model relates to a kind of arrangements for speed regulation, especially a kind of pumping unit speed regulator.
Background technique
In the oilfield exploitation evolution, replenish stratum energy to water filling and exploit once more from blowing, machine instruction statement mining, the individual well crude output is more and more lower, the extraction liquid measure is more and more higher, and flow successively decreases soon, dry grinding occurs, cause down-hole and ground installation burden to increase, make the corresponding raising of cost of production.Be to reduce the rod tube wearing and tearing, improve pump efficiency, need to reduce the jig frequency of pumping unit usually,, solve the contradiction of the fast and down-hole liquid undersupply of pumping unit to improve system effectiveness.At present, measure commonly used has: (1) uses electromagnetic adjustable speed motor, but moment of torsion is not enough during its low speed, and pumping unit can not balance, and energy consumption is higher than more than 60% of common electric machine; (2) with the motor pulley reduced diameter, the jig frequency that makes pumping unit is less than 4.5 times, and at this moment, belt and belt pulley cornerite are not enough, occurs skidding, and damages belt and belt pulley; (3) by simple addition one-level pulley decelerates, to increase velocity ratio, reduce the pumping unit rotating speed, just because of limited by the belt pulley external diameter, transmission cornerite deficiency can not normally be moved, and this mode also can not satisfy the actual conditions needs far away; (4) use multistage or slowspeed machine, perhaps frequency-variable controller, but its cost height, easy care does not also cause waste to oil field motor assets; (5) change pumping unit, this mode is not only invested huge, and the adaptability of other operating modes such as oil well extract is weakened, and is a kind of waste equally.The shortcoming of said method is the cost height, and the execute-in-place inconvenience does not fundamentally solve the low jig frequency problem, and belt damages fast, the phenomenon of stop pumping often occurs occurring because of the belt fracture.Existing in prior technology deficiency that Here it is.
Summary of the invention
The technical problems to be solved in the utility model is exactly at the existing in prior technology deficiency, and a kind of pumping unit speed regulator that can effectively realize low jig frequency is provided.
This programme is realized by following technical measures: this pumping unit speed regulator comprises horizontal stand, is positioned at big belt pulley, small belt pulley and the belt of horizontal stand top, position on the described horizontal stand between big belt pulley and small belt pulley also is provided with retarder, and the two ends of retarder link to each other with small belt pulley with big belt pulley respectively.
Above-mentioned horizontal stand is a parallelogram four-bar linkage, and the horizontal stand of this structural type can guarantee that whole speed regulator keeps level to move forward and backward.
Be connected with the adjustment leading screw in the above-mentioned horizontal stand with on the connecting rod of its frame corresponding end, move forward and backward by adjusting the connecting rod that leading screw drives in the horizontal stand with the frame opposite end, guaranteeing under the constant situation of lubricating condition, after the accent ginseng proportioning of pumping unit changes, be convenient to realize the quick tensioning of big belt pulley and small belt pulley.
The axle outside of above-mentioned retarder is set with conical sleeve, and the endoporus of big belt pulley and small belt pulley is the cone shape hole adaptive with the conical sleeve shape.This structural type can realize the quick loading and unloading of big belt pulley and small belt pulley, can also make big belt pulley and small belt pulley and conical sleeve form self-locking structure, realizes firmly assembling.
The front end of above-mentioned conical sleeve is provided with mounting groove, the opening flange is installed in the mounting groove, pass the clamping bolt that an end and big belt pulley or small belt pulley closely contacts on the opening flange, by clamping bolt with big belt pulley and more firm the fixing of small belt pulley.
The inboard front end of above-mentioned conical sleeve has thread, with conical sleeve for convenience detach, big belt pulley and small belt pulley.
The beneficial effect of this programme can be learnt according to the narration to such scheme, in this pumping unit speed regulator, position on the horizontal stand between big belt pulley and small belt pulley also is provided with retarder, the two ends of retarder link to each other with small belt pulley with big belt pulley respectively, big belt pulley links to each other with motor pulley by belt, and small belt pulley links to each other with pumping unit input shaft belt pulley by belt.By adopting retarder, increased the velocity ratio and the speed regulation precision of pumping unit effectively, reduced the jig frequency of power of motor and pumping unit effectively, both saved the energy, reduced cost of production again.This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.
Description of drawings
