Abstract
The utility model relates to a cylinder sleeve. The cylinder sleeve is hollow in the middle portion, a support ring is arranged on the outer wall at one end of the cylinder sleeve, and raised carbon scraping ring is arranged on the inner wall of the cylinder sleeve on the support ring portion. An antifriction layer is arranged on the inner wall of the hollow portion of the cylinder sleeve. By arranging the carbon scraping ring, the cylinder sleeve can improve the cleaning of impurities inside the cylinder sleeve and prolong the service life of the cylinder sleeve. The antifriction layer is arranged on the inner wall of the cylinder sleeve, and therefore the pressure resistance performance and the abrasion resistance performance of the cylinder sleeve are improved.
Description
Technical field
The utility model relates to the cylinder field, relates in particular to a kind of cylinder liner.
Background technique
Along with oil price is constantly soaring, the fuel cost that is used for the medium speed diesel of shipping and generator set improves constantly, therefore each motor producer releases heavy oil or miscella motor one after another, only have about half of light oil as fuel cost with heavy oil, but because the heavy oil carbon content is high, impurity is many, viscosity is large, therefore, and a large amount of carbon distribution that forms after the burning, these carbon distributions along with piston ring up and down reciprocatingly, cylinder liner internal wall is produced abrasive wear, form early mill, cause engine power to descend, air leak amount strengthens, and the cylinder life-span shortens.
The model utility content
In view of this, be necessary to provide a kind of and be applicable to the heavy oil environment, and long cylinder liner of life-span.
The utility model is to realize like this, a kind of cylinder liner, described cylinder liner middle part hollow out, an end outer wall of described cylinder liner is provided with support ring, cylinder liner internal wall at described support ring place is provided with the carbocyclic ring of scraping of projection, and the inwall at described cylinder liner hollow out position is provided with one deck wearing course.
Further, the described carbocyclic ring of scraping is circular protrusion.
Further, the outer wall of described cylinder liner is provided with sealing water channel.
Further, the thickness of described wearing course is 1----4mm.
The advantage of the cylinder liner that the utility model provides is: scrape carbocyclic ring by setting, improve the cleaning to cylinder liner inside impurity, improve the working life of cylinder liner.
By one deck wearing course is set at cylinder liner internal wall, improved withstand voltage properties and the wear-resisting property of cylinder liner.
The utility model cylinder liner construction is simple, with low cost, unfailing performance is high.
Description of drawings
Fig. 1 is the structural representation of the utility model cylinder liner.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
See also Fig. 1, Fig. 1 is the structural representation of the utility model cylinder liner 10.
Described cylinder liner 10 middle part hollow outs, and an end outer wall is provided with support ring 1, what cylinder liner 10 inwalls at described support ring 1 place were provided with projection scrapes carbocyclic ring 2, the inwall at described cylinder liner 10 hollow out positions is provided with one deck wearing course 3, the described carbocyclic ring 2 of scraping is circular protrusion, and the thickness of described wearing course 3 is 1----4mm.
The outer wall of described cylinder liner 10 is provided with sealing water channel 4.
In sum, the advantage of the cylinder liner that the utility model provides is: scrape carbocyclic ring by setting, improve the cleaning to cylinder liner inside impurity, improve the working life of cylinder liner.
By one deck wearing course is set at cylinder liner internal wall, improved withstand voltage properties and the wear-resisting property of cylinder liner.
The utility model cylinder liner construction is simple, with low cost, unfailing performance is high.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
