Abstract
The utility model discloses an oil production screw pump, it relates to an oil production device. It includes surface drive, drive sucker rod, stator, rotor, sealed chamber and well -flushing valve, and surface drive links to each other with the rotor through the drive sucker rod, and the rotor setting cooperatees with the stator at sealed intracavity, rotor, and the well -flushing valve sets up in the rotor below, the well -flushing valve include valve body, spring, valve ball and liquid outlet, the inside top of valve body is provided with the liquid outlet, the liquid outlet below has set gradually spring, valve ball. The utility model discloses simple structure, it is efficient to recover the oil, and the well -flushing valve is difficult for the scale deposit moreover, has improved the well -flushing effect.
Description
Technical field
The utility model relates to a kind of extracting device of oil, be specifically related to a kind of oil pumping screw pump.
Background technique
Screw pump system is a kind of novel oil production equipment, primarily of above ground portion and underground part composition.And the screw pump of part is high in underwell pump initial production, after producing the short time, Liquid output obviously declines, and mostly because Underwell leakage causes, mainly flushing valve place produces.This produces to enterprise and brings very large impact, greatly reduces enterprises production efficiency.
Model utility content
For the deficiency that prior art exists, the utility model object is to provide a kind of oil pumping screw pump, and structure is simple, and oil recovery efficiency is high, and flushing valve is less scaling, improves well washing effect.
To achieve these goals, the utility model realizes by the following technical solutions: oil pumping screw pump, comprise surface drive, drive sucker rod, stator, rotor, Seal cage and flushing valve, surface drive is connected with rotor by driving sucker rod, rotor is arranged in Seal cage, rotor matches with stator, and flushing valve is arranged on below rotor; Described flushing valve comprises valve body, spring, valve ball and liquid outlet, and valve inner top is provided with liquid outlet, is disposed with spring, valve ball below liquid outlet.
As preferably, described valve ball diameter is 25mm.
As preferably, described liquid outlet is arranged on spring fixed end top.
The utility model structure is simple, and oil recovery efficiency is high, and flushing valve is less scaling, improves well washing effect.
Accompanying drawing explanation
The utility model is described in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the flushing valve in the utility model.
Embodiment
The technological means realized for making the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the utility model further.
With reference to Fig. 1-2, this embodiment is by the following technical solutions: oil pumping screw pump, comprise surface drive 1, drive sucker rod 2, stator 3, rotor 4, Seal cage 5 and flushing valve 6, surface drive 1 is connected with rotor 4 by driving sucker rod 2, rotor 4 is arranged in Seal cage 5, rotor 4 matches with stator 3, and flushing valve 6 is arranged on below rotor 4; Described flushing valve 6 comprises valve body 61, spring 62, valve ball 63 and liquid outlet 64, and valve body 61 inner tip is provided with liquid outlet 64, is disposed with spring 62, valve ball 63 below liquid outlet 64.
It should be noted that described valve ball 63 diameter is 25mm.
In addition, described liquid outlet 64 is arranged on spring 62 fixed end top.
This embodiment, by improving the structure of flushing valve 6, makes it can meet the unlatching ability of valve, and by improving the size of valve ball 63 and going out the height of liquid level, thus improve well washing effect.
This embodiment structure is simple, and oil recovery efficiency is high, and flushing valve is less scaling, improves well washing effect.
More than show and describe basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
