Description
Technical field
The present invention relates to technical field of petroleum machinery, specially a kind of oil pump vortex type high-efficient sand-settling device.
Background technology
At present in oil exploitation, there is sandstone, impurity, the generally bottom in oil well pump in oil pumping process, in oil
Set plug, sand-settling device, antiresiduum device to be effectively isolated sandstone impurity, wherein sand-settling device is used to efficiently separate the sandstone in oil.
But existing sand-settling device is when in use, sand setting effect is poor, and sand setting speed is slow, the frequent holddown of oil well pump, makes pump damage frequency high,
Oil well pump oil pumping effect is poor.
The content of the invention
To solve the above problems, the invention discloses a kind of oil pump vortex type high-efficient sand-settling device.
In order to reach object above, the present invention provides following technical scheme：
A kind of oil pump vortex type high-efficient sand-settling device, including top connection, cylinder, lower contact, the cylinder top connect top connection,
The cylinder inner sleeve is equipped with the top of central tube, the central tube and is connected with top connection, and lower screen is provided with above the central tube
Upper screen is provided with net, the top connection, fixed block is provided between the upper screen and lower screen, the fixed block is consolidated
Surely top connection is connected, some Miao's balls are provided between the upper screen and lower screen, Miao's ball can be between upper lower screen cloth
Activity, the cylinder bottom connects lower contact, and the lower contact inner sleeve is equipped with rotary fluid, and the choosing fluidly connects the cylinder
Body, the lower contact is provided with some inlets, and the inlet, which is located at, selects fluid side, and the lower contact bottom is taper.
Further, the body of the central tube is provided with filter opening, and the bottom of the central tube is blind hole.
Further, the sieve diameter of the upper screen is less than the sieve diameter of lower screen.
Further, it is threadedly coupled between the top connection, cylinder, lower contact.
The course of work and principle of the present invention：Formation one-level settlement space between fluid and lower contact is selected, oil flows from choosing
The inlet of body side enters, and the sandstone in oil is settled in one-level settlement space, and enter lower contact connection connects sand dress
In putting, oil is further up taken out by pump, and the sandstone formed between central tube and cylinder in two grades of settlement spaces, oil is further
Sedimentation, less sandstone together enters central tube with oil from the filter opening of central tube, and then, part sandstone is hindered by lower screen
Every, more tiny sandstone is entered in the screen space formed between upper screen and lower screen with oil by lower screen,
More tiny sandstone is further separated by upper screen, and clean oil is taken away by oil pump, and sand setting effect is good, sand setting speed
It hurry up, and pump efficiency is high, the reduction of pump damage frequency.
Compared with prior art, beneficial effects of the present invention：
1st, central tube of the invention and cylinder formation one-level rotational flow settlement space, form two grades of eddy flows between rotary fluid and lower contact
Settlement space, formation two-stage rotational flow settlement space of the invention, sand setting effect is good, and sand setting speed is fast.
2nd, lower contact bottom of the invention is set to taper, can effectively collect the sandstone of sedimentation, it is to avoid sandstone raises up, sand setting
Effect is good.
3rd, screen cloth of the invention effectively obstructs comparatively fine sandstone, and lower screen can tentatively remove sandstone, upper sieve
Net further removes sandstone, and screen cloth effectively increases desanding effect, it is to avoid sandstone results in blockage to pump, reduces the damage maintenance of pump
Frequency, improves pump efficiency.
4th, central tube of the invention is designed as bottom and is provided with filter opening for blind hole body, and bottom blind hole avoids oil directly therefrom
Heart bottom of the tube enters, and oil enters from the filter opening of body, on the one hand can be easy to form effective rotational flow settlement space, on the other hand
Also there is the effect of preliminary desanding, larger sandstone is not easily accessible.
5th, Miao's ball of the invention effectively can prevent sandstone to be squeezed in sieve aperture, effectively clear up screen cloth, it is to avoid screen cloth is blocked,
Ensure pump efficiency, reduce the maintenance load of workman.
6th, structure of the present invention is novel, and easy to use, sand setting, anti-slag effect are good, effectively prevent the generation of holddown phenomenon, improves
Oil pump pumping efficiency.
