Abstract
The utility model discloses a multifunctional protector for bobbin type oil extracting pump. A traveling apparatus arranged on sucker rod of present bobbin type oil extracting pump is formed by stainless steel sheets stacked with fiber gaskets. While the fiber gasket is usually extruded out when being used, which causes the stratum turpan sand, the high wax oil and various solid formations to sink and the failures of sticking the pump or blocking the pump. A pump barrel is connected at the lower end of a sealing base through a lower collar and a float ore trap is mounted on the oil extracting rod in the sealing base. An oil pipe is connected at the upper end of the sealing base through a upper collar and a plurality of flat-tooth rings are at the external margin of the float ore trap. The utility model can effectively prevent airlock, the wax from being deposited and mechanical impurities from sticking the pump, reduce the pressure of the lower end of a plunger piston of the oil extracting pump under the dynamic status, increase the suction volume, remove the failures of sticking the pump and breaking the rod and blocking the pump caused by the stratum turpan sand and various sunk dirts on the internal wall of the oil pipe, has excellent effects and a larger market development prospect..
Description
Technical field
The utility model relates to a kind of oil extraction oil well pump, specifically is a kind of multi-function protector that is used for bobbin formula oil well pump, belongs to petroleum machinery.
Background technique
The most bobbin formula oil well pumps that adopt in present domestic oil field recover the oil, and the device of installing on this oil well pump sucker rod that moves about is to adopt that stainless steel sheets is alternate with the fiber pad to be formed by stacking, other technological deficiency of this pump structure in addition, in use the fiber pad inevitably often is extruded, and causes often to run into following insoluble problem in oil recovery process: the one, and sand is told on the stratum; The 2nd, discharge the stronger trip unity body of cohesion in the stratum; The 3rd, high wax oil; The 4th, various solid formations sink in the oil body; More than various phenomenons, caused oil well that holddown or stifled failure of pump often take place, influence oil pumping effect.
The model utility content
The purpose of this utility model is a kind of multi-function protector that is used for bobbin formula oil well pump of design, to overcome the technological deficiency that present bobbin formula oil well pump exists.
The technical solution of the utility model is:
Be connected with pump barrel by following box cupling in the sealing seat lower end, floating valve is housed on the sucker rod in sealing seat, box cupling is connected with oil pipe on passing through in the sealing seat upper end, and the sucker rod lower end is connected with plunger by locknut, and the floating valve outer rim is several flat ring gears.
The utility model can effectively be prevented gas lock, anti-wax deposition, anti-mechanical admixture holddown, reduce the pressure of oil pump plunger piston lower end under dynamically, increase intake, remove disconnected bar of the holddown that dirty dirt caused of telling sand and the various sinkings of tube inner wall in the stratum and stifled failure of pump, respond well.
Description of drawings
Accompanying drawing 1 is a main TV structure sectional drawing of the present utility model.
Accompanying drawing 2 is the A-A sectional drawing of the utility model accompanying drawing 1.
Description of reference numerals is as follows:
Oil pipe 1, last box cupling 2, sealing seat 3, floating valve 4, sucker rod 5, following box cupling 6, pump barrel 7, locknut 8, plunger 9.
Embodiment
Below in conjunction with embodiment's accompanying drawing of the present utility model the utility model is done to describe in further detail, its concrete technological scheme is:
Passing through down in sealing seat (3) lower end, box cupling (6) is connected with pump barrel (a 7) silk reed, sucker rod (5) in sealing seat (3) is gone up suit floating valve (4), be connected with oil pipe (1) silk reed by last box cupling (2) in sealing seat (3) upper end, sucker rod (5) lower end is connected with plunger (9) by locknut (8).
Floating valve (4) outer rim is 8 flat ring gears.
When under sucker rod (5) plunger (8) that the lower end connected towards the time, floating valve (4) is very fast whereabouts and sealing seat (3) closure under the effect of deadweight and oil column gravity, oil column gravity is limited in sealing seat (3) top, be convenient to down-hole fluid and under the non-resistance state, enter plunger (8), when plunger (8) is up, floating valve (4) is by automatic jack-up, and fluid enters oil pipe (1) in the flat ring gear of floating valve (4) and sealing seat (3).
The utility model is simple in structure, and is easy to install, and the plunger compression time is short; can effectively prevent gas lock, reduce sucker rod wax deposition and mechanical admixture holddown, the protection strata pressure improves pump efficiency; can generally be used in bobbin formula oil well pump, have bigger market development prospect.
Claims (2)
1. multi-function protector that is used for bobbin formula oil well pump; formed by the plunger (8) that locknut (8) connects by oil pipe (1), sucker rod (5) and sucker rod (5) lower end; box cupling (6) is connected with pump barrel (7) to it is characterized in that passing through down in sealing seat (3) lower end; on the sucker rod (5) in sealing seat (3) floating valve (4) is housed, is connected with oil pipe (1) by last box cupling (2) in sealing seat (3) upper end.
2. a kind of multi-function protector that is used for bobbin formula oil well pump according to claim 1 is characterized in that described floating valve (4) outer rim is several flat ring gears.
