Abstract
A kind of mud pump sleeve belongs to the pipeline protection technique field of equipment.This mud pump sleeve includes a main body and the connecting flange for being separately positioned on main body both ends, main body uses tubular construction, the centre of main body is thick, both ends are thin, cross section is ellipse, it is set in the middle part of main body there are one rectangle flange, multiple Length discrepancy through holes and a circular hole is equipped in the main body in the oval flange hole of rectangle flange.The tube-in-tube structure is reasonable, and original welding scheme is changed to hot investment casting one-pass molding, reduces internal flaw, the sealing performance of container can be improved, simultaneously can also reduce product deformation and subsequent production in allowance, reduce casting with processing cost, improve production efficiency.
Description
Technical field
The utility model is related to a kind of mud pump sleeve, for mud or water to be conveyed in drilling process in drilling
The machinery of flushing liquors is waited, belongs to the pipeline protection technique field of equipment.
Background technology
Zhong ﹐ slush pumps are drilled by earth's surface scouring media-Qing Shui ﹑ mud or polymer flush fluid one in common direct circulation
Under fixed pressure, the bottom of drill bit is directly sent to through the soft pipe ﹑ taps of excessively high pressure and drill string central hole, is bored with reaching cooling
The landwaste cut is removed and is transported to earth's surface by head.It further needs exist for considering the factors such as equipment attrition, corrosion, it is ensured that
There is sufficiently long normal service life.
The content of the invention
In order to ensure the reliably working of drilling equipment, the utility model provides a kind of mud pump sleeve, the sleeve
Should be rational in infrastructure, welding scheme after original casting is changed to hot investment casting one-pass molding, internal flaw is reduced, can improve
The sealing performance of container, at the same can also reduce product deformation and subsequent production in allowance, reduce casting with
The cost of processing, improves production efficiency.
The technical solution adopted in the utility model is：A kind of mud pump sleeve, it includes a main body and difference
It is arranged on first connecting flange and the second connecting flange at main body both ends, the main body uses tubular construction, the centre of main body is thick,
Both ends are thin, and cross section is ellipse, set in the middle part of main body there are one rectangle flange, in the ellipse of rectangle flange
Main body in flange hole is equipped with multiple Length discrepancy through holes and a circular hole, and the cylindrical surface of first connecting flange is equipped with the
One through hole and the second through hole.
The quantity of the Length discrepancy through hole is 12, is arranged in the surrounding of the circular hole.
It is linked together between the rectangle flange and main body by connecting tube of the section for ellipse.
The beneficial effects of the utility model are：This mud pump sleeve includes a main body and is separately positioned on master
The connecting flange at body both ends, main body use tubular construction, and the centre of main body is thick, both ends are thin, and cross section is ellipse, in main body
Middle part is set there are one rectangle flange, and multiple Length discrepancies are equipped in the main body in the oval flange hole of rectangle flange
Through hole and a circular hole.The tube-in-tube structure is reasonable, and original welding scheme is changed to hot investment casting one-pass molding, reduces internal lack
Fall into, the sealing performance of container can be improved, while can also reduce product deformation and subsequent production in allowance, drop
Low casting and the cost of processing, improve production efficiency.

Specific embodiment
It becomes apparent from intactly illustrating the utility model by way of example and in conjunction with the accompanying drawings.
Fig. 1,2,3 are a kind of structure charts of mud pump sleeve.In figure, this mud pump includes one with sleeve
A main body 1 and the first connecting flange 2 and the second connecting flange 4 for being separately positioned on 1 both ends of main body.Main body 1 uses tubular construction,
The centre of main body 1 is thick, both ends are thin, and cross section is ellipse, is set in the middle part of main body 1 there are one rectangle flange 3, in length
Main body 1 in the oval flange hole of square flange 3 is equipped with a multiple Length discrepancy through hole 1a and circular hole 1b.First connection method
The cylindrical surface of orchid 2 is equipped with first through hole 2a and the second through hole 2b.The quantity of Length discrepancy through hole 1a is 12, is arranged in institute
State the surrounding of circular hole 1b.It is linked together between rectangle flange 3 and main body 1 by connecting tube 3a of the section for ellipse.
Using above-mentioned technical solution, the middle part of main body is the Length discrepancy through hole that 12 length do not wait, and Length discrepancy leads to
The centre in hole is 25 circular holes of φ, one end of main body there are one the first connecting flange, on the cylindrical surface of the first connecting flange there are two
Through hole has 4 M12 threaded holes in the plane of the first connecting flange.The other end of main body be the second connecting flange, the second connection method
There are 4 M12 threaded holes in blue plane.There are one rectangle flange, rectangle methods for the middle part of main body, the outside of Length discrepancy through hole
It is linked together between blue and main body by connecting tube, connection tube section is ellipse.There are 4 companies in the plane of rectangle flange
Connect hole.
