Abstract
The utility model belongs to an oil-well pump, which is suitable for the sufficiency of liquid-supply. The continuous liquid-supply oil-well pump is mainly composed of a travelling valve (1), a single flow valve (2), a fixing sealing block (3), a liquid filling single flow valve (4), a piston (5), a pump cylinder (6), a travelling sliding block (7) and a fixing valve (8), wherein, the moving element piston (5), the travelling sliding block (7), the outer surface, the fixing sealing block (3), the inner surface of the pump cylinder (6) of the continuous liquid-supply oil-well pump can be in surface technical processing; the hardness can reach 70 DEG. Therefore, the utility model has the advantages of wear resistance and long service life; an upper and a lower stoke oil sucking pumps of the oil sucking pump can both carry out continuously liquid-supply; the discharge capacity is high; the utility model has the characteristics that the fluid flow state of an oil layer can be improved, and the productivity can be raised.
Description
The utility model belongs to a kind of oil well pump, is applicable to the feed flow abundance, the oil well that lifting rate is high, particularly a kind of continuous feed liquor oil well pump.
Water flooding enters the later stage, and oilwell produced fluid amount raises, moisture rising, common oil well pump is because feed liquor when up stroke only, can not feed liquor during down stroke, and the limited requirement that can not satisfy discharge opeing of pump delivery, the cost of repairs height though the electric pump well discharge capacity is big, the operating cost height.
Goal of the invention of the present utility model is to provide a kind of continuous feed liquor oil well pump according to the problems referred to above, and this continuous liquid oil well pump is to adopt two valve feed liquor principles, has solved not problem such as feed liquor and operating cost height of down stroke.
Accompanying drawing is continuous feed liquor oil well pump sectional drawing.
The utility model is that a kind of continuous feed liquor oil well pump of realization like this (as figure) mainly is made up of travelling valve (1), one-way valve (2), fixing seal piece (3), feed liquor one-way valve (4), piston (5), pump barrel (6), the slide block that moves about (7), standing valve (8), there is travelling valve (1) upper end of piston (5), there is the slide block of moving about (7) lower end, there is one-way valve (2) upper end of fixing seal piece (3), and the lower end has feed liquor one-way valve (4) travelling valve (8) to be contained in the lower end of pump barrel (6).
Movement parts piston of the present utility model (5), the slide block that moves about (7) outer surface, fixing seal piece (3) and pump barrel (6) internal surface are all handled through sufacing, hardness can reach 70 degree, therefore wear-resisting, the all continuous feed liquor of long service life, the upper and lower stroke oil well pump of pumping unit, the discharge capacity height, have the reservoir fluid of improvement flowing state, increase the characteristics of output.
Below in conjunction with accompanying drawing an embodiment is described: after piston (5), the slide block that moves about (7) outer surface and fixing seal piece (3), pump barrel (6), the internal surface chromium plating after at first car being become is handled again be processed into after travelling valve (1), one-way valve (2), sealing block (3), feed liquor one-way valve (4) assembling.
Claims (1)
1, a kind of continuous feed liquor oil well pump mainly is made up of travelling valve (1), one-way valve (2), fixing seal piece (3), feed liquor one-way valve (4), piston (5), pump barrel (6), the slide block that moves about (7), standing valve (8), there is the slide block of moving about (7) lower end that it is characterized in that piston (5), there is one-way valve (2) upper end of fixing seal piece (3), and there is feed liquor one-way valve (4) lower end.
