Abstract
The utility model discloses an oil well linkage drug adding pump which mainly solves the problems of the prior drug adding pump that a sealing piece is easy to wear, and the pump does not add drugs after a drug box is fed with the drugs. The oil well linkage drug adding pump is characterized in that an oil chamber sealing body (3) is arranged in a spring sleeve seat (1) and is internally and sequentially provided with a sealing ring (4) and a sealing oil chamber (5), and a plunger is tightly contacted with the sealing ring (4) and the sealing oil chamber (5); the lower end of the oil chamber sealing body (3) is connected with a pump body (2), a drug flow channel (6) for communicating with the top and the bottom is transversely arranged in the pump body (2), a step hole at an axial section of the drug flow channel (6) is provided with a valve ball (7), one end of the pump body (2) is connected with an upper flow joint (8) and a lower flow joint (9), and the valve ball (7) is arranged in a step hole of the upper flow joint (8). The oil well linkage drug adding pump has the advantages that the sealing piece is difficult to wear, the service life is long, and the pump continue to add the drugs without shutdown after the drug box is fed with the drugs.
Description
Technical field:
The utility model relates to the used medicine adding device of well head, especially oil well linkage type dosing pump in the oil recovery field, oil field.
Background technique:
In oil recovery field, oil field, in order to prevent underground equipment wax deposition and fouling, need in the well liquid of down-hole, add the medicament of anti-wax deposition and fouling, guarantee that underground equipment normally moves.At present,, generally use the mode that dosing pump is installed on well head, in the well liquid of down-hole, add anti-wax deposition and fouling medicament, make anti-wax deposition and fouling medicament to carry out dosing according to the oil well pump laws of motion in order to guarantee to add dose.And at present the oil well dosing pump is because reasons in structure exists the problem that pump after the easy to wear and medicine-chest dosing of Sealing does not help medicine, and influence is normally recovered the oil.
The model utility content:
In order to solve the problem that pump after the easy to wear and medicine-chest dosing of existing dosing pump Sealing does not help medicine; the utility model provides a kind of oil well linkage type dosing pump, this oil well linkage type dosing pump has that Sealing is not easy to wear, the life-span is long and the medicine-chest dosing after do not shut down the characteristics that pump continues to help medicine.
The technical solution of the utility model is: this oil well linkage type dosing pump comprises the pump housing and spring housing cylinder base, the spring housing cylinder base is built-in with grease chamber's seal, be disposed with seal ring and seal oil chamber in grease chamber's seal, plunger closely contacts with seal ring and seal oil chamber; Seal lower end, grease chamber is connected with the pump housing, and the stream medicine passage up and down that is connected is laterally arranged in the pump housing, is equipped with valve ball on the stream medicine passage axial direction part step hole, and the pump housing one end is connected with upper and lower stream joint, and upper reaches joint step hole is built-in with valve ball.
The utlity model has following beneficial effect: this oil well linkage type dosing pump is owing to take such scheme, because of having adopted two kinds of compound seal modes of seal ring and seal oil chamber, seal oil chamber and plunger do not have friction, and seal ring is by offering machine oil in the seal oil chamber, friction factor also reduces greatly, so prolonged the working life of seal ring, improves sealing reliability, reinforced suction power, the ordinary production of assurance oil well.Again because of having adopted stream medicine passage up and down; and on stream medicine passage step hole and be placed with valve ball in the joint step hole of upper reaches; make after the medicine-chest dosing; need not to stop pumping unit and just can continue proper functioning; thereby reduced dead time, improved the working efficiency of oil recovery well, reduced labor strength; solve the problem that does not obtain fine solution for many years, guaranteed the ordinary production of oil well then.This oil well linkage type dosing pump has that Sealing is not easy to wear thus, the life-span is long and the medicine-chest dosing after do not shut down the characteristics that pump continues to help medicine.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation.
1-spring housing cylinder base among the figure, the 2-pump housing, 3-grease chamber seal, 4-seal ring, 5-seal oil chamber, 6-stream medicine passage, 7-valve ball, 8-upper reaches joint, the dirty joint of 9-.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, this oil well linkage type dosing pump comprises the pump housing 2 and spring housing cylinder base 1, and spring housing cylinder base 1 is built-in with grease chamber's seal 3, is disposed with seal ring 4 and seal oil chamber 5 in grease chamber's seal 3, and plunger closely contacts with seal ring 4 and seal oil chamber 5; Seal 3 lower ends in grease chamber's are connected with the pump housing 2, the stream medicine passage 6 up and down that is connected is laterally arranged in the pump housing 2, be equipped with valve ball 7 on the stream medicine passage 6 axial direction part step holes, the pump housing 2 one ends are connected with upper reaches joint 8 and dirty joint 9, and joint 8 step holes in upper reaches are built-in with valve ball 7.
During actual the use, at first this oil well linkage type dosing pump is fixed on the well head, upper reaches joint 8 is communicated with the down-hole again, dirty joint 9 is communicated with medicine-chest, gets final product proper functioning.When the pumping unit down stroke, polished rod drives plunger and moves downward, and at this moment the valve ball 7 in the upper reaches joint 8 moves upward, and passage is opened, and soup injects the down-hole, finishes the dosing process.When the pumping unit upstroke, polished rod drives plunger and moves upward, at this moment the valve ball 7 in the upper reaches joint 8 is closed, the pathway closure that is communicated with oil well, valve ball 7 in flowing on medicine passage 6 step holes simultaneously moves upward under the effect of draft, the passage that is communicated with medicine-chest is opened, and soup enters in the upper reaches medicine passage 6, finishes the process of aspiration medicinal liquid.Like this in the process that pumps of pumping unit, this oil well linkage type dosing pump along with pumping unit clocklike to the down-hole dosing, realize quantitatively that regularly circuit is to the down-hole dosing.Owing to adopted seal ring 4 and 5 two kinds of compound seal modes of seal oil chamber, seal oil chamber 5 does not have friction with plunger, and seal ring 4 is by offering machine oil in the seal oil chamber 5, friction factor also reduces greatly, so prolonged the working life of seal ring 4, improve sealing reliability, reinforced suction power, the ordinary production of assurance oil well.Again because of having adopted stream medicine passage 6 up and down; and on stream medicine passage 6 step holes and be placed with valve ball 7 in upper reaches joint 8 step holes; make after the medicine-chest dosing; need not to stop pumping unit and just can continue proper functioning; thereby reduced dead time, improved the working efficiency of oil recovery well, reduced labor strength; solve the problem that does not obtain fine solution for many years, guaranteed the ordinary production of oil well then.This oil well linkage type dosing pump has that Sealing is not easy to wear thus, the life-span is long and the medicine-chest dosing after do not shut down the characteristics that pump continues to help medicine.
