Description
Technical field
The invention belongs to oil pumping in oil fields pump technical field, more particularly to a kind of vortex automatically cleaning oil well pump.
Background technology
In recent years, oil field at home enters successively the exploitation later stage, is corroded after chip and down-hole chemical sand control operation by tube rod
Sand-fixating agent etc. has sticking suspended impurity to be affected, and causes the problems such as oil well pump holddown, leakage more to project, subject matter performance
：1）Rust piece, the dirty suspended impurity such as piece and down-hole silt particle, potting resin, gel produced in oil jacket annular space, sucks oil well pump
Afterwards, deposit near standing valve, cause standing valve to block or poorly sealed；2）In lower pump operation, roofbolt scratch tube inner wall is produced
Raw iron filings and scaling enter in pump chamber, cause to have accumulated full junk before oil pumping pump work at standing valve, directly affect standing valve
Keying.Problem above causes pump detection period short, and maintenance cost is high, affects production efficiency.For the sticky contaminant that down-hole suspends,
Conventional oil well pump cannot be discharged in time, and the sand-preventing pump for using is more based on sand setting structure, and store up sand limited space, to such impurity
Treatment effect is unsatisfactory.
The content of the invention
To overcome above-mentioned the deficiencies in the prior art, it is an object of the invention to provide being to provide a kind of vortex automatically cleaning oil pumping
Pump, for having sticking suspended impurity in clean-up pump, prevents impurity from depositing in pump chamber；It is total that the pump devises eddy flow standing valve
Device structure is risen into vortex rotation, the well liquid for making carrying impurity is produced eddy flow after standing valve and raised speed, and logical in upper and lower stroke
Cross vortex rotation and rise device by the rotary motion that is converted to rotor of sliding up and down of plunger, the local eddy currents of generation are to the impurity in pump chamber
Play a part of stirring rotation to rise, impurity is discharged inside pump chamber, realize self-cleaning function, solve oil well pump because of down-hole dirt thing shadow
Holddown, the problem of leakage rung and produce, effectively extends pump detection period, improve production efficiency.
For achieving the above object, the technical solution used in the present invention is：One kind vortex automatically cleaning oil pumping pump configuration, includes
