Abstract
The utility model discloses an enhancing device for pump efficiency. The enhancing device comprises a sucker rod (2) in an oil pumping pipe (1). The enhancing device is characterized in that the sucker rod (2) is provided with an oil extracting piston (3) axially floating along the sucker rod (2); the external side of the oil extracting piston (3) is provided with a seal ring (4) matching with the internal diameter of the oil pumping pipe (1); a plurality of oil holes (5) are evenly and axially distributed in a position where the oil extracting piston (3) is close to the sucker rod (2); an upper end cap (6) and a lower end cap (7) are respectively fastened over the sucker rod (2) and below the oil extracting piston (3); a plurality of notches (8) are evenly distributed on the external circumference of the upper end cap (6) and the lower end cap (7); and the lower end of the oil extracting piston (3) is provided with a tapered part (9). The enhancing device for pump efficiency is simply structured with smart design; and by the use of the enhancing device, oil leakage and stroke loss are reduced and work efficiency of an oil pump is increased.
Description
Technical field
The utility model relates to a kind of pump oil device, particularly a kind of pump efficiency height-increasing device.
Background technique
The oil well pump that oil field is used, between its plunger and pump barrel, for existing the problem of leakage, this problem can cause the negative pressure in pump barrel to reduce, thereby affects oil inlet quantity, reduces the working efficiency of oil well pump.Along with long exploitation, the degree of depth of oil well increases gradually, the elastic elongation of sucker rod is also increasing, its loss of plunger stroke is also day by day serious, when entering the middle and later periods of exploitation, because long-term geology changes, can there is corrosion-deformation in pump barrel sleeve pipe simultaneously, oil pipe bends, and causes the connection mouth of oil pipe partly to be missed.Generally speaking, for various reasons, As time goes on production efficiency can reduce existing oil well pump, therefore needs now a kind of Novel oil well pump structure that can address the above problem.
Summary of the invention
The utility model is in order to solve the existing above-mentioned deficiency of prior art, proposes a kind of simple in structurely, designs ingeniously, can reduce oily wastage, reduces loss of plunger stroke, improve the pump efficiency height-increasing device of oil well pump working efficiency.
Technical solution of the present utility model is: a kind of pump efficiency height-increasing device, comprise the sucker rod 2 that is positioned at oil pick-up tube 1, it is characterized in that: on described sucker rod 2, being provided with can be along the oily piston 3 of carrying of its axial float, in the arranged outside of carrying oily piston 3, there is the seal ring 4 matching with oil pick-up tube 1 internal diameter, carry oily piston 3 near the part of sucker rod 2, offer vertically a plurality of equally distributed oilholes 5, carry on the sucker rod 2 of above and below of oily piston 3 and be fixedly installed respectively upper plug head 6 and lower end cap 7, and on the excircle of upper plug head 6 and lower end cap 7, be also provided with a plurality of equally distributed breach 8, the lower end of carrying oily piston 3 is provided with tapering part 9.
Compared with the existing technology, tool has the following advantages the utility model:
The pump efficiency height-increasing device of this kind of structural type, it is simple in structure, designs ingenious.A plurality of pump efficiency height-increasing devices are according to certain distance interval, being arranged on sucker rod of series connection, each pump efficiency height-increasing device is equivalent to an one-way valve, oil cannot flow downward after entering in pump efficiency height-increasing device, thereby realizes the segmented seal of oil pick-up tube and carry oil, this mode can significantly reduce the beam hanger pressure on oil pump plunger piston, when reducing oil well pump leakage, in oil pick-up tube, form higher negative pressure, increase the filling index of oil inlet quantity and oil well pump; This segmentation is simultaneously put forward oily mode and has also been reduced the elasticity prolongation of sucker rod in up stroke process, reduces loss of plunger stroke, and then reaches the object of crude oil volume increase.Its preparation process is simple, cheap for manufacturing cost simultaneously, therefore can say that it has possessed multiple advantage, is particularly suitable for applying in the art, and its market prospects are very wide.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment's structural representation.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.As shown in Figure 1: a kind of pump efficiency height-increasing device, comprise the sucker rod 2 that is positioned at oil pick-up tube 1, on sucker rod 2, be provided with and carry oily piston 3, and this carry oily piston 3 can be on sucker rod 2 axial float, the seal ring 4 that has the internal diameter with oil pick-up tube 1 to match in the arranged outside of carrying oily piston 3, offer oilhole 5 carrying the core of oily piston 3 (near the part of sucker rod 2), and oilhole 5 is a plurality of, on circumference, be uniformly distributed, on the sucker rod 2 of above and below of carrying oily piston 3, be also fixedly installed respectively upper plug head 6 lower end caps 7, on the excircle of upper plug head 6 and lower end cap 7, be also provided with a plurality of equally distributed breach 8 simultaneously, in the lower end of carrying oily piston 3, be provided with tapering part 9, it can seal up breach 8.
The working procedure of the utility model embodiment's pump efficiency height-increasing device is as follows: when sucker rod 2 is descending, oil phase is for up in oil pick-up tube 1, and enter the cavity between lower end cap 7 and upper plug head 6 by the breach 8 on lower end cap 7 excircles, then continuing uply by the oilhole of carrying on oily piston 3, to enter the cavity of carrying between oily piston 3 and upper plug head 6, is now normal oil pumping state;
When sucker rod 2 is up, under the effect of deadweight and oil pressure, carry oily piston 3 descending with respect to lower end cap 7, carry the tapering part 9 of oily piston 3 lower ends and be arranged on the seal ring 4 of carrying on oily piston 3 excircles and jointly say breach 8 sealings on lower end cap 7, oil remains in carries oily piston 3 tops, realizes the segmented seal of oil pick-up tube 1.
Claims (1)
1. a pump efficiency height-increasing device, comprise the sucker rod (2) that is positioned at oil pick-up tube (1), it is characterized in that: on described sucker rod (2), being provided with can be along the oily piston of carrying of its axial float (3), in the arranged outside of carrying oily piston (3), there is the seal ring (4) matching with oil pick-up tube (1) internal diameter, carry oily piston (3) near the part of sucker rod (2), offer vertically a plurality of equally distributed oilholes (5), carry on the sucker rod (2) of above and below of oily piston (3) and be fixedly installed respectively upper plug head (6) and lower end cap (7), and be also provided with a plurality of equally distributed breach (8) on the excircle of upper plug head (6) and lower end cap (7), the lower end of carrying oily piston (3) is provided with tapering part (9).
