Abstract

The utility model discloses a high-efficiency gas-exhaust oil well pump with oil baffle plates. The pump comprises an outer main pipe; an oil pump main body is sleeved in the outer main pipe and is provided with a pump core, an oil drainage device, a valve ball seat and a liquid inlet pipe in turn; an oil return pipe is sleeved in the liquid inlet pipe; an upper part of the outer main pipe is provided with gas exhaust ports, liquid inlet ports are disposed below the gas exhaust ports on the outer main pipe, a lower part of the liquid inlet pipe is provided with liquid inlet openings, and the oil baffle plates are arranged between the outer main pipe and the oil pump main body. By using the high-efficiency air-exhaust oil well pump provided by the utility model, the problem that oil cannot be normally exploited when gases in a pump cylinder are not effectively exhausted during oil exploitation is solved.

Description

A kind of efficient oil baffle exhaust oil well pump

Technical field

The utility model belongs to the oil exploration equipment technical field, relates to a kind of efficient oil baffle exhaust oil well pump.

Background technique

When carrying out petroleum production with oil well pump, often can run into have bubble in pump barrel, and raise when a large amount of bubbles can not get will making when effectively discharging the pump barrel internal air pressure, cause and can't normally recover the oil.

Summary of the invention

The purpose of this utility model is to provide a kind of efficient oil baffle exhaust oil well pump, has solved when petroleum production in pump barrel that gas can not get effectively discharging and the normal problem of recover petroleum.

The technological scheme that the utility model adopts is, a kind of efficient oil baffle exhaust oil well pump, comprise the ectosome supervisor, be socketed with the oil pump main body in the ectosome supervisor, the oil pump main body is disposed with pump core, oil drainer, anti-that ball seat and liquid inlet pipe from top to bottom, is socketed with in liquid inlet pipe and returns oil pipe, ectosome supervisor top has relief opening, have liquid entering hole below ectosome supervisor's relief opening, the bottom of liquid inlet pipe has inlet opening, is provided with oil baffle between ectosome supervisor and oil pump main body.

The beneficial effects of the utility model are, the setting by oil baffle splashes fluid to scatter, and then a large amount of gas is discharged from, and make oil to be exploited smoothly.

Description of drawings

Fig. 1 is the structural representation of a kind of efficient oil baffle exhaust oil well pump of the utility model.

In figure, 1. ectosome supervisor, 2. oil pump main body, 3. pump core, 4. oil drainer, 5. anti-your ball seat, 6. liquid inlet pipe, 7. return oil pipe, 8. relief opening, 9. liquid entering hole, 10. inlet opening, 11. oil baffles.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.

The utility model provides a kind of efficient oil baffle exhaust oil well pump, as shown in Figure 1, comprise ectosome supervisor 1, be socketed with oil pump main body 2 in ectosome supervisor 1, oil pump main body 2 is disposed with pump core 3, oil drainer 4, anti-that ball seat 5 and liquid inlet pipe 6 from top to bottom, be socketed with in liquid inlet pipe 6 and return oil pipe 7, ectosome supervisor 1 top has relief opening 8, ectosome supervisor 1 relief opening 8 belows have liquid entering hole 9, the bottom of liquid inlet pipe 6 has inlet opening 10, is provided with oil baffle 11 between described ectosome supervisor 1 and oil pump main body 2.

liquid entering hole 9 in oil well pump of the present utility model is higher than the bottom of pump core 3, when oil well pump is worked, form the space between ectosome supervisor 1 and oil pump main body 2, so during liquid entering hole 9 feed liquor, the downward sedimentation of liquid, gas is along the upwards diffusion of ectosome supervisor 1 inwall, owing to being provided with oil baffle 11 between ectosome supervisor 1 and oil pump main body 2, so when liquid during from liquid entering hole 9 feed liquor, the sedimentation downwards of liquid left and right, and large quantity of fluid is splashed by oil baffle 11 and is scattered, and then a large amount of gases are discharged from, alleviated like this air pressure in pump barrel, the oil of down-hole can be exploited out smoothly.

Claims

1. efficient oil baffle exhaust oil well pump, it is characterized in that, comprise ectosome supervisor (1), be socketed with oil pump main body (2) in ectosome supervisor (1), oil pump main body (2) is disposed with pump core (3) from top to bottom, oil drainer (4), anti-that ball seat (5) and liquid inlet pipe (6), be socketed with in liquid inlet pipe (6) and return oil pipe (7), ectosome supervisor (1) top has relief opening (8), have liquid entering hole (9) below ectosome supervisor's (1) relief opening (8), the bottom of liquid inlet pipe (6) has inlet opening (10), be provided with oil baffle (11) between described ectosome supervisor (1) and oil pump main body (2).
