Abstract
The invention provides a speed reducer for an oil pumping unit and relates to a speed reduction device, in particular to a speed reduction device for an oil pumping unit. The speed reducer for the oil pumping unit comprises an oil pumping rod, a piston and a pump cylinder, wherein the oil pumping rod is fixedly arranged at the upper part of the piston; and the piston is arranged inside the pump cylinder in a sliding manner. The speed reducer is characterized in that the lower part of the piston is connected with a speed reduction slide block through a connecting rod; and a breathing hole communicated with the pump cylinder is formed between the piston and the speed reduction slide block. The speed reducer for the oil pumping unit has the benefits that through forming the breathing hole between the piston and the speed reduction slide block and by utilizing oil pressure difference generated at the upper part and the lower part of the speed reduction slide block, the load of a horse head suspension point is reduced, a pump hanger is additionally arranged, and the pump efficiency is improved; and the speed reducer has simple structure and very strong practicality.
Description
Technical field
The present invention relates to a kind of speed reducer, particularly a kind of speed reducer for oil pumping unit.
Background technique
Prolongation along with the oil field development time, mineral resources are more and more rare, deeply buried reservoir, stratum energy are low, poor permeability, the poor oil reservoir of flood effectiveness obtain being exploited more and more, for this class oil reservoir mainly adopt little pump deeply the mode of taking out exploit, the existing little pump deeply technology of taking out is subject to the restriction of the specified polished rod load of pumping unit and sucker rod quality, the lower pump degree of depth is subject to certain restrictions, and is difficult to satisfy the needs of oil field development.
Summary of the invention
The pump degree of depth under a kind of growth of the present invention, the oil pump speed reducer of alleviation reconnaissance load.
A kind of oil pump speed reducer of the present invention.
A kind of speed reducer for oil pumping unit of the present invention, by between piston and deceleration slide block, spiracle being set, and utilize the poor horse head polished rod load that alleviates of oil pressure that therefore is created in deceleration slide block upper and lower part, increase pump and hang, improve pump efficiency, the simple and practical property of the present invention is very strong.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention 1.
Among the figure: the 1-sucker rod; The 2-piston; The 3-pump barrel; The 4-spiracle; 5-deceleration slide block.
Embodiment
Embodiment 1.
A kind of oil pump speed reducer of the present invention, comprise sucker rod 1, piston 2 and pump barrel 3, sucker rod 1 is fixedly installed on piston 2 tops, piston 2 slides and is arranged at pump barrel 3 inside, the plug bottom connects a deceleration slide block 5 by connecting rod, is provided with the spiracle 4 with pump barrel 3 conductings between described piston 2 and the deceleration slide block 5.
The present invention links together sucker rod 1, piston 2, deceleration slide block 5, move up and down with sucker rod 1, because the shutoff of piston 2 and deceleration slide block 5, so that form a hollow between the upper-end surface of the lower end surface of packed-piston 2 and deceleration slide block 5, this hollow is communicated with pump barrel 3 by spiracle 4, therefore the pressure of hollow is identical with the pressure of annular space, so the upper and lower end face of the slide block 5 that slows down has an oil pressure poor, the thrust that is produced by this pressure difference makes it produce a lifting force that makes progress in the lower end surface of deceleration slide block 5.When pumping unit horsehead is up, the deceleration slide block 5 suffered power of lifting auxiliary pumping units drive sucker rod 1 and move upward, the load of pumping unit is alleviated, also alleviated simultaneously the pulling force of deceleration slide block 5 top sucker rods 1, accelerated the speed uplink of pumping unit, when pumping unit horsehead is descending, deceleration slide block 5 is driven by the sucker rod 1 of its underpart and moves downward, because the deceleration slide block 5 suffered power of lifting that make progress still exist, so the descending speed of pumping unit slows down, this has also just in time met up fast, the descending slow energy-saving principle of pumping unit.Pumping unit so pumps, and has alleviated the horse head polished rod load, also so that increase the pump extension in former base of design.
