Abstract
The utility model relates to an anti-leaking oil pump which is a device for a pumping well in an oil field. The anti-leaking oil pump comprises an upper pump cylinder joint, a pump cylinder, a plunger assembly, a lower pump cylinder joint and an oil inlet valve, wherein the upper pump cylinder joint, the pump cylinder, the lower pump cylinder joint and the oil inlet valve are connected in turn; the plunger assembly is arranged in the pump cylinder; an upper part of a coupling is connected with a lower exterior of the upper pump cylinder joint; a lower part of the coupling is connected with the upper part of a sealing pipe; the lower part of the sealing pipe is connected with the upper part of an adapter connector; the sealing pipe and the adapter connector are sleeved on the pump cylinder; the upper part of a sealing sleeve is connected with the lower part of the adapter connector; the sealing sleeve is sleeved on the lower pump cylinder joint; a sealing ring is arranged between the sealing sleeve and the lower pump cylinder joint; and a closed space is arranged between the pump cylinder and the sealing pipe. After the pump cylinder is corroded and perforated, the interior of the pump cylinder is still under sealing state and the oil pump still can normally pump oil, so that the service life of the oil pump is prolonged, the production cycle of the oil well is increased, the output of the oil well is increased and the economic benefit is obvious.
Description
Technical field
The utility model is the equipment that oil field pumping well is used, and is a kind of leakproof oil well pump.
Background technique
In the oil pumping of oil field, every mouthful of pumping well is all wanted next oil well pump, and the pump barrel of oil well pump need seal and not leak and could normally pump.But in the oil well of the anti-eccentric wear of lower liner oil pipe, the pump barrel of oil well pump is bored a hole easily, makes its pump barrel and oil well casing UNICOM, and oil well pump loses the oil pumping function, causes oil well stopping production inspection pump, causes heavy economic losses.
Summary of the invention
The purpose of the utility model is a kind of leakproof oil well pump of design, still can normally pump after making the pump barrel perforation of its oil well pump, prolongs the working life of oil well pump, increases the oil well production cycle.
The purpose of the utility model is achieved in that and comprises pump barrel joint, pump barrel, plunger piston assembly, following pump barrel joint, oiling valve; Last pump barrel joint, pump barrel, following pump barrel joint, oiling valve connect successively, and plunger piston assembly is in pump barrel, and box cupling top is connected with last pump barrel joint is outside down; The box cupling bottom is connected with sealed pipe top; The sealed pipe bottom is connected with change snapping head top, and sealed pipe, change snapping headgear are contained in outside the pump barrel, and stuffing box gland top is connected with change snapping head bottom; Stuffing box gland is sleeved on down outside the pump barrel joint, between stuffing box gland and the following pump barrel joint seal ring is arranged.
The beneficial effect of the utility model is: be enclosed space between pump barrel and the sealed pipe; Behind the pump barrel corrosion failure, still be in closed state in the pump barrel, oil well pump still can normally be pumped; Can prolong the working life of oil well pump; Increase the oil well production cycle, improve oil well output, have remarkable economic efficiency.
Description of drawings
Fig. 1 is the utility model embodiment's a erection drawing.
Embodiment
Below in conjunction with Fig. 1 the utility model embodiment is described.
Can be known that by figure the embodiment of the utility model comprises pump barrel joint 1, pump barrel 4, plunger piston assembly 5, pump barrel joint 9, oiling valve 10 down, last pump barrel joint 1, pump barrel 4, descend pump barrel joint 9, oiling valve 10 to connect successively, plunger piston assembly 5 is in pump barrel 4; 1 time outside connection of box cupling 2 tops and last pump barrel joint, connecting thread is a tubing round thread, and screw thread can seal, and box cupling 2 bottoms are connected with sealed pipe 3 tops; Connecting thread is a tubing round thread, and screw thread can seal, and sealed pipe 3 bottoms are connected with change snapping head 6 tops; Connecting thread is a tubing round thread, and screw thread can seal, and sealed pipe 3, change snapping head 6 are sleeved on outside the pump barrel 4; Stuffing box gland 7 tops are connected with change snapping head 6 bottoms, and connecting thread is regular screw threads, leans on end face seal; Stuffing box gland 7 is sleeved on down outside the pump barrel joint 9, between stuffing box gland 7 and the following pump barrel joint 9 seal ring 8 is arranged, and is enclosed space between pump barrel and the sealed pipe thereby make; After pump barrel 4 perforation, sealed pipe 3 seals, and the utility model still can normally be pumped.
