Abstract
The utility model relates to a direct-pumping type oil field pumping unit of a permanent magnet disk type motor, comprising the permanent magnet disk type motor, a main frame and an oil pump; the pumping unit is characterized in that the permanent magnet disk type motor (1) is fixed with the bottom of the main frame (3); the two ends of a motor main shaft (11) are respectively provided with large sprocket wheels (7-1 and 7-2) which are respectively provided with chains (4-1 and 4-2) meshed with the large sprocket wheels; and the two ends of the chains (4-1 and 4-2) are respectively connected with an oil pump polish rod (5) and a balance weight vehicle (6) by small sprocket wheels (12). The oil pump is directly driven by low-speed high torque of the permanent magnet disk type motor; as a plurality of motors can be connected in series for operation, the working motors can be flexibly increased or reduced according to different oil well output volume and liquid feeding capability of the stratum when in operation; furthermore, by adjusting the movement mode of the oil pump polish rod, the oil pumping operation can achieve the best effect, so that the working efficiency is improved, and the pumping unit can be widely applied to oil pumping operation of oil fields and oil wells.
Description
Technical field
The utility model relates to the equipment of the oil pumping operation of oilfield, and is specifically a kind of, no walking beam permanent magnet disc motor direct-drawing type oil pumper.
Background technology
At present, the equipment of the oil pumping operation of oilfield mainly is connecting-rod beam formula oil pumper, and its main power source mostly is threephase asynchronous, reducing gear adopts belt transmission and reducer to slow down, and balance mode mostly is the crank spin balancing, indirectly balance, counterbalance effect is restricted, and reactive power consumption is big.This oil pumper structure is more numerous, and energy consumption is higher, and whole efficiency is undesirable, and stroke and motor pattern are non-adjustable.
The utility model content
The purpose of this utility model is in order to provide a kind of simple in structure, to have significantly improved the oil pumper whole work efficiency, energy efficient, and can realize increasing more conveniently and reduce to pump the permanent magnet disc motor direct-drawing type oil pumper of torsion assortment of load.
Described a kind of permanent magnet disc motor direct-drawing type oil-field oil pumper, comprise permanent magnet disc motor, frame, oil well pump, it is characterized in that: described permanent magnet disc motor and mainframe bottom are fixing, be respectively equipped with hinge wheel at the electric machine main shaft two ends, be respectively equipped with the chain with its engagement on hinge wheel, the two ends of chain are connected with oil pump polished rod and weight vehicle by minor sprocket respectively.
Chain on the homonymy hinge wheel is connected with oil pump polished rod, weight vehicle respectively by minor sprocket.
Described permanent magnet disc motor stator dish is two sides band teeth groove and the whole iron core that is embedded with coil, and its rotor disk is that two single faces all are pasted with many flat tray type structure to permanent magnetic iron.
Described permanent magnet disc motor rotor disk also can be the two-sided flat tray type structure that all is pasted with many to permanent magnetic iron, and its stator dish is two one-side band teeth groove and the whole iron core that is embedded with coil.
One end of described electric machine main shaft also can be connected with another same parameter permanent magnet disc motor main shaft by Cardan shaft.
The utility model utilizes the low-speed big of permanent magnet disc motor directly to drive oil well pump, because but the multiple electric motors tandem is exerted oneself, also can be according to oil well discharge capacity and stratum fluid supply capacity when operation different, increase or reduce the work of motor neatly, and the motor pattern of oil pump polished rod, make the oil pumping operation reach optimum efficiency, improved operating efficiency.
The utility model structure is simpler, and easy to connect, stable working, energy-efficient is installed, and can be widely used in the oil pumping operation of oilfield.
