Description

Deep well detector stator blank

Technical Field

The utility model belongs to the technical field of the oil machinery, in particular to deep well detector stator blank.

Background

In the petroleum industry, the structure of a finished stator product of a deep well detector in the prior art comprises an inner sleeve, blades and an outer sleeve, wherein transition inclined planes are arranged at the outer diameter of each blade and the inner diameter end part of the outer sleeve. Because the stator blade needs good wear resistance in a deep well state, the stator blade is usually made of two materials, namely 17-4PH dual-phase steel and cobalt-based alloy material, because the structure of the stator blade is complex, the design of a casting die is difficult, in the prior art, a bar material or a pipe material is processed through machining procedures such as wire cutting, a numerical control lathe, a machining center and the like, and the problems that the yield of the material is low and the production cost is increased exist.

Disclosure of Invention

The utility model aims to solve the technical problem overcome prior art's weak point, provide and to realize endotheca, overcoat and blade casting deep well detector stator blank as an organic whole to improve the yield and the structural strength of material, reduction in production cost.

The utility model discloses a technical scheme include endotheca and overcoat, have the blade at the outer wall circumferencial direction equipartition of endotheca, the length of overcoat is less than the length of endotheca, overcoat and blade casting structure as an organic whole, endotheca and overcoat are straight tube structure, are equipped with the transition inclined plane in the external diameter of every blade and the left end internal diameter combination department of overcoat, and the external diameter of the exposed blade that spills the overcoat part is greater than the internal diameter of overcoat, is equipped with conical rising head at the right-hand member internal diameter of endotheca to be equipped with first processing allowance at the internal diameter of endotheca respectively, 2 terminal surfaces and the right-hand member face of overcoat are equipped with the second processing allowance about the endotheca, are equipped with the third processing allowance at the external diameter of overcoat, are equipped with the fourth processing.

6 blades are uniformly distributed on the outer wall of the inner sleeve in the circumferential direction.

The first machining allowance of the inner diameter of the inner sleeve is equal to the second machining allowances of the left end face, the right end face and the right end face of the inner sleeve and the outer sleeve, and the first machining allowances are 3-5 mm.

And the third machining allowance of the outer diameter of the outer sleeve is 2-6 mm.

And the fourth machining allowance of the exposed outer diameter of the blade leaking out of the outer sleeve part is 1-3 mm.

Compared with the prior art, the beneficial effects of the utility model are that, will endotheca, overcoat and blade casting structure as an organic whole to adopt the blank structure that is close with stator finished product structure, the right-hand member face of 2 terminal surfaces and overcoat about the internal diameter of endotheca, the overcoat external diameter all is equipped with the machining allowance with the exposed blade external diameter that spills the overcoat part, process the machining allowance respectively and can accomplish stator finished product processing, it is low to have solved the product yield that is finished product material with bar or pipe material processing, increase manufacturing cost's problem, the product yield of material has been improved, the production beat has been accelerated, reduction in production cost.
