Description
(1) technical field
The utility model relates to the transmission gear shift mechanical device that rotatablely moves, and particularly is the energy-conservation transmission device of a kind of pumping unit low jig frequency.
(2) background technique
The oil field development middle and later periods, oil well that the production fluid amount is low and thick oil well power consumption are big, and the cost height is of poor benefits.Its basic reason is down-hole oil reservoir feed flow deficiency and causes pump efficiency to reduce, even the free phenomenon of taking out.In order to solve the dynamically middle fluid of oil well production for the contradiction that should not take out, can reduce the pumping unit jig frequency or reduce stroke, in fact the change of stroke is subjected to the type restriction, and adjustable extent is less, mainly is to satisfy each oil well jig frequency coupling requirement by reducing the pumping unit jig frequency.Reducing one of method that the pumping unit jig frequency adopts usually is to change the medium and small diameter pulley of little transmission device, and GB minimum diameter allowable is 200mm, when diameter during less than 160mm, because of cornerite is too little, easily skids, and quickens the belt wearing and tearing, and minimum jig frequency can only reach 4 times/minute.Two of method is to adopt multipole several motors, reduces rotating speed, and not only motor cost increases, and 8 utmost point motors can only make the pumping unit jig frequency drop to 3 times/minute, still can not satisfy the requirement of many oil wells.Three of method is to adopt electromagnetic adjustable speed motor, though can make pumping unit realize 0～9 time/minute stepless speed regulation, low cruise is not steady, and the power consumption of motor excitation part is more, and motor cost and operation and maintenance cost are higher.Four of method is to adopt variable-frequency governor, though economize on electricity can reach about 30%, cost is higher, and management difficulty is big, inapplicable open-air unmanned oil well environment.In addition, also have the conversion of Single-chip Controlling star angle, or,, all can not satisfy the requirement that pumping unit reduces jig frequency though certain energy-saving effect is arranged by the speed governing of electric control cubicle control oil pumping motor.Chinese patent " oil pump energy-saving retarder " (02268408) is that the transmission of one-level belt pulley is become the transmission of two-stage belt pulley, reach the purpose that reduces the pumping unit jig frequency, though energy-saving effect is better than above-mentioned the whole bag of tricks, but to transform again and increase installing space the old pumping unit erecting bed, both increased more investment, it is time-consuming to require great effort again, influences crude oil production, also is unfavorable for the large-scale popularization application.
(3) summary of the invention
In view of above-mentioned prior art all has tangible deficiency, the utility model is broken through conventional thought, and other wards off the fork footpath, no longer motor itself is taked technical measures, but drive part is optimized combination, provide a kind of distinguished pumping unit low jig frequency energy-conservation transmission device.Reach the requirement of both satisfying the special low jig frequency optimum Match of each oil well, again purpose of energy saving significantly.
Above-mentioned purpose is realized by following technical proposals:
The energy-conservation transmission device of pumping unit low jig frequency is a driving force with the motor, adopts the belt pulley kind of drive, it is characterized in that being formed by motor, retarder and belt pulley assembling.The output shaft and the input shaft of speed reducer of motor fixedly link, and on the output shaft of retarder belt pulley are installed, and the three is connected into as a whole by axle and key assembling.The two casing joint of retarder and motor adopts flange plate to add nut and is fixedly connected.Belt pulley directly is contained in the extension of reducer output shaft.This transmission device is fixedly mounted on the oil pumping unit base by the support of retarder.
The retarder of this transmission device adopts cycloidal-pin wheel retarder or other mechanical transmission retarder.
There is a blind hole thread at the center, reducer output shaft exterior edge face of this transmission device, is used for installing baffle plate, prevents the belt pulley slippage.
The cycloidal-pin wheel retarder that the utility model is used, be the novel transmission gear shift machinery that adopts K-H-V fewer differential teeth planetary formula transmission principle and the engagement of cycloid pin tooth, have that reduction speed ratio is big, efficient is high, running is steady, noise is little, many outstanding advantages such as compact structure, easy for installation, long service life.Use it for the pumping unit field, in aggregates with motor, belt pulley optimum organization, as the new transmission device of pumping unit, be important innovations part of the present utility model.Preliminary examination proves, adopts one-level cycloidal-pin wheel retarder, the pumping unit jig frequency can be reduced to 1～3 time/minute scope, and economize on electricity can reach 50～70%; Can adopt 15KW, 18.5KW, 22KW motor to replace the motor of original 37KW, 45KW, 55KW respectively, transformer capacity also correspondingly reduces, and not only economizes on electricity but also save the power equipment investment; Owing to reduced the system-wide motion speed of pumping unit, can alleviate transmission, motion parts, and the tired and wearing and tearing of oil well pump and sucker rod, prolonged working life and plant maintenance cycle; Especially can prolong 2～3 times the working life of belt, correspondingly reduce replacing belt number of times, alleviate the amount of labour, strive for the more oil pumping production time; The pumping unit all system operates steadily, safe and reliable, more be applicable to impact, dynamic load, long-term continuous operation; This transmission structures compactness, volume is little, and is in light weight, can be directly installed on the position of original motor, and installs and removes very conveniently, except regularly adding the machine oil, almost need not other maintenance cost.
