Abstract
The utility model relates to an oil enhancing device of a pumping device, which mainly solves the problems of the prior oil enhancing device that: the structure is complicated and the installation and exchange is not convenient. A spring (6) and an upper righting sleeve (3), a lower righting sleeve (7) are set through a polished rod (1) between a square clip (2) and a rope suspending device (8) and the top end and the lower end of the spring (5) are set in the holes of the upper righting sleeve (3) and the lower righting sleeve (6); and guard sleeves (4) are outlaid on the upper righting sleeve (3), the spring (5) and the lower righting sleeve (6) and the lower end of the spring is connected with the lower righting sleeve (6) and the top end comprises a square clip (2) and a center hole. When the oil enhancing device is in upward stroke of the pumping device, the closing time of the travelling valve in the down-well plunger pump relatively lags and the time of the oil entering into the pump barrel is increased, therefore the pump input is increased and the yield is increased.
Description
Technical field
The utility model relates to the oil increasing machine structure that can improve oilwell produced fluid amount in a kind of oil well oil recovery, specifically a kind of oil pumper oil increasing device.
Background technology
Down-hole oil production instrument common and that the supporting use of oil pumper is recovered the oil is a reciprocating plunger pump, under the drive of oil pumper, pump and realize upwards carrying of oil mixed liquor, because the influence of the hysteresis of moving valve in the pump barrel and standing valve motion, oil pick-up tube inwall wax deposition, fouling, cause the soakage leakage of pump, the operating efficiency of pump is reduced.In order to improve the soakage of plunger displacement pump, the general way that solves is in the sucker rod on pump barrel top, down-hole oil increasing device to be set, and this class oil increasing device structure more complicated, it is cumbersome that replacing is installed, also increased simultaneously the live load of oil well pump, and along with the oil increasing device prolongation of service time, appearance wax deposition in various degree and sand card phenomenon do not have and increase oil effect.
The utility model content
For the complex structure that solves existing oil increasing device, the inconvenient problem of changing is installed, this is practical newly to provide a kind of oil pumper oil increasing device, this oil increasing device is simple in structure, be easy to install and change.
The technical solution of the utility model is: a kind of oil pumper oil increasing device, comprise the square clamp of fixing polished rod and be through at polished rod eye on the polished rod, be installed with spring on the polished rod between described side's clamp and polished rod eye and go up supporting positive cover, supporting positive cover, and the upper and lower side of spring down and place in the hole of supporting positive cover up and down; And go up supporting positive cover, spring, the following external casing of supporting positive cover, and its lower end is connected the centre bore that its side of having, upper end clamp can move within it with following supporting positive cover.
The beneficial effects of the utility model are: owing to adopt technique scheme, between square clamp on the polished rod and polished rod eye seat, wear a spring, when the oil pumper upstroke, need overcome the tension force of spring, just can continue upwards the generation hysteresis effect time on after making its compression, and the time of opening of the travelling valve in the plunger displacement pump of down-hole also prolongs relatively, the time that fluid enters pump barrel also increases thereupon, thereby has increased the amount of pumping into, and has played the effect that increases oil.

Accompanying drawing 1 is a structural representation of the present utility model;
1-polished rod 2-side clamp 3-goes up supporting positive cover 7-polished rod eye 8-driving hole under the supporting positive cover 4-casing 5-spring 6-
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Shown in accompanying drawing 1, this oil pumper oil increasing device comprise fixing polished rod 1 square clamp 2, be through at the polished rod eye 7 on the polished rod 1, supporting positive cover 3 on the following supporting positive cover 6 that is installed with spring 5 and lower end thereof on the polished rod 1 of 7 of square clamp 2 and polished rod eyes, upper end, and the upper and lower side of spring 5 places supporting positive cover (3 up and down, 6) in the hole, last supporting positive cover 3, spring 5 reach the supporting positive cover 6 outer casings 4 that are equipped with down, casing 4 can play the safeguard protection effect to spring, casing 4 lower ends are threaded with supporting positive cover 6, there is centre bore casing 4 upper ends, and square clamp 2 can move axially in its hole; Have on the supporting positive cover 6 and be convenient to the driving hole 8 that is connected is installed with casing 4 screw threads.
During the operation of oil pumper down stroke, this oil increasing device can move down synchronously with polished rod 1, travelling valve in the plunger displacement pump of down-hole is opened, standing valve cuts out, and when the oil pumper upstroke is moved, when the wire rope on the polished rod eye 7 moves up under the drive of oil pumper, at first to overcome the tension force of spring 5 and compress spring 5, when spring 5 is compressed to extreme position, could move up with polished rod 1 and square clamp 2, like this, the travelling valve shut-in time in the plunger displacement pump of down-hole is relatively lagged behind, the time that fluid enters pump barrel also increases thereupon, thereby has increased the amount of pumping into, and has played to increase the effect that oil improves output.This oil increasing device is applicable to that mainly daily output is greater than 10 tons oil pumper.
Claims (1)
1, a kind of oil pumper oil increasing device, comprise the square clamp (2) of fixing polished rod (1) and be through at polished rod eye (7) on the polished rod (1), it is characterized in that: be installed with spring (5) on the polished rod (1) between square clamp (2) and polished rod eye (7) and go up supporting positive cover (3), following supporting positive cover (6), and the upper and lower side of spring (5) places in the hole of supporting positive cover (3,6) up and down; And last supporting positive cover (3), spring (5) and the following external casing of supporting positive cover (6) (4) and lower end are connected with following supporting positive cover (6), the centre bore that its upper end side's of having clamp (2) can move within it.
