Description
Technical field
The utility model relates to a kind of oil production equipment, particularly a kind of pumping unit of oil well.
Background technology
During ultradeep well recovers the oil, oil well pump is all single pump, because the degree of depth of oil well is deep, oil well pump stroke is larger, and the pump leakage that makes to pump is larger, and the loss of recovering the oil is excessive, oil recovery efficiency is not very desirable, has reduced the economy of recovering the oil, and can not meet production requirement.
Utility model content
Goal of the invention of the present utility model is: the problem existing for prior art, provides a kind of pumping unit of oil well of quick detachable, grease proofing re-injection.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of pumping unit of oil well, comprise central axis, in described central axis, be provided with ball seat, in described ball seat, be provided with valve ball, described ball seat upper end is provided with ball cover, on described central axis, be provided with cannelure, in described cannelure, be provided with leakproof kitchen apron, described leakproof kitchen apron upper end is provided with arc convex, described leakproof kitchen apron lower end and central axis are affixed, described leakproof kitchen apron lower end arranged outside has retainer ring, in described cannelure, leakproof kitchen apron lower end is provided with locating ring, on described locating ring, be provided with support skirt, described locating ring can slide up and down in cannelure, described locating ring is screwed on central axis, described support skirt is wrapped in leakproof kitchen apron outside.
As preferred version of the present utility model, described support skirt top edge is wrapped in arc convex lower edge on leakproof kitchen apron.
As preferred version of the present utility model, described locating ring and support skirt are iron, steel or carbon steel alloy.
As preferred version of the present utility model, on described central axis, be at least provided with two groups of leakproof kitchen aprons and locating ring, can reach better oil-leakage-prevention effect, improve the extraction of oil mass.
In sum, owing to having adopted technique scheme, the beneficial effects of the utility model are: simple in structure, easy to operate, can reach the effect that prevents oily re-injection, and safe and reliable, leakproof kitchen apron is easily changed, and has saved cost for oil production.
