Description
Technical field
The utility model relates to a kind of oil well pump Junk prevention protector.
Background technology
Most domestic oil field adopts oil pumper to carry out oil recovery and produces, along with the production in oil field, oil well output can reduce gradually, moisture meeting raises gradually, and oil well hole condition can slowly be deteriorated, the various situations being unfavorable for producing such as oil well easily occurs wax deposition, shakes out, fouling, eccentric wear, corrosion, in well, easily the various dirty sheet of generation, wax stone, etched sheet, sand grains, tool wear fall block etc., cause the jam of oil well pump, leakage, valve malfunctioning, oil well pump cisco unity malfunction, affects the normal production of oil well.
Although each elephant takes certain measure for junks such as the wax in oil well, dirt, sand, also devise some anti-block instruments, all fail fundamentally to stop dirt to fall into pit shaft, solve the oil well pump jam problem because junk causes.
Therefore need to study a kind of simple effective method, realize in oil well production process, stop the junks such as wax, dirt, sand to fall in pit shaft, prevent the generation of oil well pump jam situation, ensure that oil well pump normally aspirates to reach, oil well is normally produced, the object of Extended Pump Detection Period.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of oil well pump Junk prevention protector; to realize in oil well production process, stop the junks such as wax, dirt, sand to fall in pit shaft, prevent the generation of oil well pump jam situation; ensure that oil well pump normally aspirates, the normal production of oil well.
The technical solution of the utility model is:
A kind of oil well pump Junk prevention protector, its special character is: comprise pipe, card holding trough, beam hanger in top connection, outer tube, " shuttle " shape valve, interior pipe, storage chamber, flushing screw, lower contact, " shuttle " shape valve; Described interior pipe is arranged in lower contact; Described outer tube bottom is connected with lower contact; Outer tube top is connected with top connection; Described outer tube, lower contact and interior pipe form storage chamber; Described " shuttle " shape valve is two flaps, is sleeved on beam hanger by card holding trough, and described " shuttle " shape valve can slide on beam hanger, and described " shuttle " shape valve and beam hanger contact surface are manage in " shuttle " shape valve.
Above-mentioned " shuttle " shape valve surface has water conservancy diversion screw thread.
The bottom of above-mentioned outer tube is provided with flushing screw.
Between above-mentioned each parts, connected mode is for being threaded.
The utility model has the advantage of:
When oil well pump normally works; " shuttle " shape valve is in interior pipe top always; in oil well pump, liquid stream can enter oil pipe by space between " shuttle " shape valve and interior pipe; then storage chamber is fallen into along the thread surface of " shuttle " shape valve after the junk sedimentations such as the wax in oil pipe, dirt, sand; the junks such as wax, dirt, sand can not enter oil pump sleeve; prevent the generation of oil well pump jam, serve the protective effect of oil well pump Junk prevention.

Detailed description of the invention
See Fig. 1, a kind of oil well pump Junk prevention protector, comprises top connection 1, outer tube 2, " shuttle " shape valve 3, interior pipe 4, storage chamber 5, rinses pipe 8, card holding trough 9, beam hanger 10 in screw 6, lower contact 7, " shuttle " shape valve; Described interior pipe 4 is arranged in lower contact 7; Described outer tube 2 bottom is connected with lower contact 7; Outer tube 2 top is connected with top connection 1; Described outer tube 2, lower contact 7 and interior pipe 4 form storage chamber 5; Described " shuttle " shape valve 3 is two flaps, is sleeved on beam hanger 10 by card holding trough 9, and described " shuttle " shape valve 3 can slide on beam hanger 10, and described " shuttle " shape valve 3 and beam hanger 10 contact surface are pipe 8 in " shuttle " shape valve.There is water conservancy diversion screw thread on " shuttle " shape valve 3 surface.The bottom of outer tube 2 is provided with rinses screw 6.Between each parts, connected mode is for being threaded.
Using method of the present utility model:
The using method of oil well pump Junk prevention protector:
(1), under during oil well pump operation, oil well pump Junk prevention protector lower contact 7 is connected to the top of oil well pump, top connection 1 is connected with oil pipe;
(2) under during oil pump plunger piston operation, be sleeved on oil pump plunger piston on first beam hanger 10 by " shuttle " shape valve 3, " shuttle " shape valve 3 can slide on beam hanger 10;
(3) when oil well is normally produced, upstroke: " shuttle " shape valve 3 is by actings in conjunction such as gravity, frictional force and liquid flowing resistances, " shuttle " shape valve 3 is in interior pipe 4 top, and the water conservancy diversion screw thread on " shuttle " shape valve 3 surface reduces the resistance that liquid flows through, and liquid stream can pass through smoothly.Down stroke: " shuttle " shape valve 3 is by actings in conjunction such as gravity, frictional force and liquid flowing resistances, and cover on interior pipe 4 top, the junk such as wax, dirt, sand of " shuttle " shape valve 3 top sedimentation falls into storage chamber 5 along thread surface;
(4) during oil well overhaul, take out oil well pump Junk prevention protector, lay down and rinse screw 6, clean, installed by flushing screw 6 after cleaning with clear water to protector storage chamber 5, protector can continue to use.
Oil well pump Junk prevention protector carries out designing and developing according to conventional oil pipe specification, mechanism makes every effort to simple, is convenient to mounting, commissioning and maintenance maintenance.Its " shuttle " shape valve 3 adopts flap-type to design, and is convenient to fitting operation; In " shuttle " shape valve, pipe 8 adopts superhigh molecular weight polyethylene material to make, and has wear-resistant, shock resistance and self-lubricating property; " shuttle " shape valve surface devises water conservancy diversion screw thread, to reduce the resistance of liquid stream.Oil well pump Junk prevention protector can effectively stop the junks such as wax, dirt, sand to enter pump barrel, prevents the generation of oil well pump jam.
Operating principle of the present utility model is:
Oil well pump Junk prevention protector is arranged on oil-well pump of oil well top.When oil well is normally produced, upstroke: " shuttle " shape valve 3 is by actings in conjunction such as gravity, frictional force and liquid flowing resistances, and " shuttle " shape valve 3 is in interior pipe 4 top, the water conservancy diversion screw thread on " shuttle " shape valve 3 surface reduces the resistance that liquid flows through, and liquid stream can pass through smoothly.Down stroke: " shuttle " shape valve 3 is by actings in conjunction such as gravity, frictional force and liquid flowing resistances, and cover on interior pipe 4 top, the junk such as wax, dirt, sand of " shuttle " shape valve 3 top sedimentation falls into storage chamber 5 along thread surface; Protector can effectively stop the junks such as wax, dirt, sand to enter pump barrel, prevents the generation of oil well pump jam.
When oil well carries out pump detection and workover, take out oil well pump Junk prevention protector, lay down and rinse screw 6, clean, installed by flushing screw 6 after cleaning with clear water to protector storage chamber 5, protector can continue to use.
