Abstract
The utility model discloses a cylinder sleeve for a mud pump, which comprises a cylinder sleeve body and is characterized in that a ceramic inner layer is arranged on the inner wall of the cylinder sleeve body. The cylinder sleeve body is a high-carbon high-chrome body, a clamp groove is arranged at one end of the cylinder sleeve body, and a boss is arranged at the other end of the cylinder sleeve body. The ceramic inner layer is coated on the inner wall of the cylinder sleeve body so that friction between the cylinder sleeve and a piston is reduced and abrasion resistance of the cylinder sleeve is improved. Simultaneously, the ceramic coating prolongs service life of the cylinder sleeve and enables service life of the cylinder sleeve to be more than 5 times compared with a normal duplex metal cylinder sleeve.
Description
Technical field
The utility model relates to the cylinder sleeve field, specifically, relates to a kind of slurry pump and uses cylinder sleeve.
Background technique
Slurry pump is the core of oil drilling platform, and mud slurry pump cylinder jacket promptly is the vitals of slurry pump, is again the easily worn part of slurry pump, and its wear resistance and working life are by the problem of extensive concern.At present, most of mud slurry pump cylinder jacket is a bi-metal liner, because working condition is abominable, bi-metal liner wears no resistance, and is easy to impairedly, and working life is short, is merely 300-400 hour the working life of bi-metal liner at present.When complicated geology or petroleum reservoir are dark, need usually change cylinder sleeve, thereby have a strong impact on drilling efficiency, be prone to come off influence production when Metallic cylinder uses with slurry pump equipment back simultaneously.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned defective, provides the slurry pump of a kind of wear-resisting, long service life and difficult drop-off to use cylinder sleeve.
For addressing the above problem, the technological scheme that the utility model adopted is:
A kind of slurry pump is used cylinder sleeve, comprises the cylinder sleeve body, it is characterized in that: the inwall of said cylinder sleeve body is provided with ceramic inner layer.
Further say:
Said cylinder sleeve body is the high carbon and chromium body.
One end of said cylinder sleeve body is provided with draw-in groove.
The other end of said cylinder sleeve body is provided with boss.
Owing to adopted technique scheme; Compared with prior art, on the inwall of cylinder sleeve body, be coated with one deck ceramic inner layer in the utility model, reduced the frictional force between cylinder sleeve and the piston; Improved the wear resistance of cylinder sleeve; Simultaneously, ceramic coating has also increased the working life of cylinder sleeve, and be more than 5 times of common double Metallic cylinder working life.
Below in conjunction with accompanying drawing and embodiment the utility model is done further description.
Description of drawings
Accompanying drawing is a kind of embodiment's of the utility model a structural representation.
Among the figure: the 1-draw-in groove; 2-cylinder sleeve body; The 3-ceramic inner layer; The 4-boss.
Embodiment
Embodiment:
A kind of slurry pump is used cylinder sleeve, shown in accompanying drawing, comprises the ceramic inner layer 3 on cylinder sleeve body 2 and the inwall that is arranged on cylinder sleeve body 2.In the present embodiment, cylinder sleeve body 2 is the high carbon and chromium body.The cylinder sleeve body that high carbon and chromium is processed has high wear-resisting property, corrosion resistance and high hardness, uses indeformable for a long time.Ceramic inner layer has very strong anticorrosive and antiwear property, is difficult for impairedly, can prolong simultaneously working life of cylinder sleeve greatly, and be more than 5 times of common double Metallic cylinder its working life.
In the present embodiment, be provided with draw-in groove 1 at an end of cylinder sleeve body, the other end of cylinder sleeve body is provided with boss 4, and draw-in groove compound rubber circle cooperates boss again, increases the stability that cylinder sleeve combines with slurry pump.
During use, the boss 4 of cylinder sleeve and the corresponding site of draw-in groove 1 and slurry pump are closely cooperated, increase the stability that cylinder sleeve and slurry pump cooperate, in case of necessity, can in groove, increase rubber band, make stability better.When having guaranteed slurry pump work like this, cylinder sleeve is difficult for coming off from slurry pump, reduces the required time of maintenance, has reduced production, has improved manufacturing efficiency simultaneously.
Claims (4)
