Description
Technical field
The present invention relates to pumping unit field, a kind of particularly variation device.
Background technique
Existing pumping unit generallys use beam pumping unit, the disadvantage is that volume is big, swims depth of beam at 5 meters or more.
In use, sucker rod pumps in oil pipe, well head sealing packing is vulnerable part, needed after using abrasion into
Row replacement.Replacement operation needs two people cooperation, and needs replacement in one day primary, and staff labor intensity is very big.And packing is frequent
Abrasion be accompanied by the leakage of Wellhead crue oil, will cause environmental pollution.
Summary of the invention
In order to solve the problems, such as that existing beam pumping unit maintenance is inconvenient.The present invention provides a kind of variation device, the changes
Dynamic device and pulley casing can be combined into novel pumping unit, which can by the variation device and gear-box
Pumping for sucker rod is converted by the rotary motion of motor, not only reduces volume management easy to repair, it can be with
So that the sealing means of well head is changed into mechanical seal by packing_seal, good sealing effect can be played.
The present invention solves technological invention used by its technical problem: a kind of variation device, including sequentially connected defeated
Enter to hold transmission shaft, driving crank, eccentric shaft, change crank, fixing axle, spur rack and synchromesh gear, in input terminal transmission shaft
It is parallel to each other between heart line, the center line of eccentric shaft, the center line of fixing axle and the center line of synchromesh gear, spur rack is connected with
Mobile position-limit mechanism, the movement position-limit mechanism move spur rack can only along the length direction of spur rack, be driven in input terminal
During the unidirectional continuous rotation of axis, synchromesh gear is capable of the angle of the rotation setting of two way alternate.
The beneficial effects of the present invention are:
1, pumping for sucker rod is converted for the rotary motion of motor by the variation device and pulley casing, from
And the sealing means of well head is made to be changed into mechanical seal by packing_seal, good sealing effect can be played.
2, operation is safer, and highest point is only higher by 1.5 meters than well head in the overall structure of the novel pumping unit, relatively passes
The height that the beam pumping unit of system moves then 5 meters or more reduces very much, great convenience Operations,Administration And Maintenance, and operator
Without climbing again, security risk when operation is reduced.
3, structure is simple, management convenient for safeguarding.Compared to more traditional beam pumping unit, the novel pumping unit globality
Height, transmission mechanism have using case internal gear oil lubrication, do not need frequent external lubrication maintenance, reduce the labor of operator
Fatigue resistance.
4, the hermetically sealed of well head is realized.Well head is connected and sealed by pulley casing, and transmission mechanism is by machine between each cabinet
Tool sealing is sealed, and is substantially improved well head leakage situation, is solved the problems, such as environmental pollution.
5, the replacement frequency of traditional packing_seal is greatly reduced.Well mouth sealing device is replaced by mechanical seal, is not used
Packing_seal, the replacement cycle of common packing_seal are 1 to 3 day, and the average life of mechanical seal more than half a year, from
And the labor intensity for replacing seal operation is substantially reduced.
6, it is greatly saved airtight and watertight padding, reduces production cost.Common packing_seal 50 yuan one, mechanical seal
500 yuan or so one, 10 packing_seals of every replacement are equivalent to the price using a mechanical seal, and packing_seal is more
Changing the period is 1 day to 3 days, changes calculating with 3 days one, is equivalent within one month one mechanical seal of consumption, and mechanical seal is flat
Equal service life is more than half a year, so more cost-effective using mechanical seal.
7, structure is simple, and materials are saved, and production technology is uncomplicated, and more traditional beam pumping unit is cheaper.
8, it is mainly used in heavy oil wells production, thin oil well can also be used, and sealing effect is more preferably.Since thin oil well well head leaks
Mistake situation is lighter, and traditional pumping unit and sealing means are sufficient for production requirement.
