Abstract
The utility model relates to a dedicated energy-saving device for an oil pumping unit in an oil field. The dedicated energy-saving device comprises an electric motor, a speed reducer, a coupling and a belt pulley, wherein an output shaft of the electric motor is connected with the coupling through a key; an input shaft of the speed reducer is connected with the coupling through a key; and the belt pulley is arranged on the output shaft of the speed reducer. The dedicated energy-saving device has an important innovation as follows: a cycloidal pin gear speed reducer adopted in the field of the oil pumping unit is combined with the electric motor and the belt pulley so as to form a whole body in an optimal manner, and the whole body is used as a new transmission device of the oil pumping unit. The dedicated energy-saving device has the advantages of compact structure, small volume and light weight, and can be directly installed in the position of the original electric motor; the electric motor and the speed reducer are connected through the coupling, so that disassembly and assembly are convenient, time and labor can be saved, and maintenance cost is saved when the electric motor or the speed reducer is damaged and maintained.
Description
Technical field
The utility model relates to a kind of transmission gear shift mechanical device, particularly a kind of oil-field oil pumper private energy-saving apparatus.
Background technology
In the oil field development middle and later periods, oil well that the production fluid amount is low and heavy oil wells power consumption are big, expensive poor benefit.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 under-supply contradiction of fluid of oil well production, generally can adopt and reduce the oil pumper jig frequency, but in fact the change of stroke at first 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 oil pumping jig frequency.One of general method that reduces the common employing of oil pumper jig frequency is to change the medium and small diameter pulley of little transmission device, 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, reduce rotating speed, not only motor cost increases, 8 utmost point motors can only use the oil pumper jig frequency to drop to 3 times/minute, still can not satisfy the requirement of many oil wells, and three of method is to adopt electromagnetic adjustable speed motor, though the stepless speed regulation that oil pumper is realized 0-9 time/minute, but 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.Method four is to adopt variable-frequency governor, though economize on electricity reaches about 30%, cost is higher, and management difficulty is big, incompatible open-air unmanned oil well environment.
The utility model content:
The utility model provides a kind of oil-field oil pumper private energy-saving apparatus, by to running part optimum organization, reaches the requirement of both satisfying the special low jig frequency optimum Match of each oil well, again purpose of energy saving significantly.
The purpose of this utility model is achieved through the following technical solutions: a kind of oil-field oil pumper private energy-saving apparatus, comprise motor, reducer, shaft joint and belt pulley, the output shaft of motor is connected by key with shaft joint, reducer input shaft is connected by key with shaft joint, and the output shaft of reducer is provided with belt pulley.
Described reducer adopts cycloidal-pin wheel reducer or other machine driving reducer.
The cycloidal-pin wheel reducer that the utility model adopts in the oil pumper field, in aggregates with motor, belt pulley optimum organization, as the new transmission device of oil pumper, be important innovations part of the present utility model.Many outstanding advantages such as the cycloidal-pin wheel reducer has that speed reducing ratio is big, efficient is high, running is steady, noise is little, compact conformation, easy for installation, long service life.Preliminary examination proves, adopt one-level cycloidal-pin wheel reducer, the oil pumper jig frequency can be reduced to 1～3 time/minute scope, economize on electricity can reach 50～70%, can adopt 15KW, 18.5KW, the 22KW motor replaces original 37KW respectively, 45KW, the motor of 55KW, transformer capacity also correspondingly reduces, not only economize on electricity but also save the power equipment investment, owing to reduced the system-wide speed of service of oil pumper, can alleviate transmission, motion parts, and the tired and wearing and tearing of oil well pump and sucker rod, application life and plant maintenance cycle have been prolonged, especially can prolong 2～3 times the application life of belt, correspondingly reduced replacing belt number of times, alleviated the amount of labour, striven for the more oil pumping production time, the oil pumper total system operates steadily, safe and reliable, more be applicable to impact, dynamic loading, long-term continuous operation, the utility model compact conformation, volume is little, and is in light weight, can be directly installed on the position of original motor, the utility model motor is connected by shaft joint with reducer, can easy disassembly when motor or reducer damage maintenance, time saving and energy saving, and save maintenance cost.
