Description
Technical field
The utility model relates to a kind of cylinder sleeve, specifically a kind of casting engine of boat and ship cylinder sleeve.
Background technique
Cylinder sleeve of engine is the cylindrical metal parts guiding piston to carry out straight reciprocating motion in cylinder.Thermal energy is mechanical energy by expanding by working medium in cylinder sleeve of engine; Gas receiving piston in compresser cylinder compresses and improves pressure.At present in engine of boat and ship, more particularly than relatively large cylinder sleeve, there is cylinder sleeve life-span too short problem, trace it to its cause, the cooling of cylinder sleeve is just in the middle part of cylinder sleeve, and cylinder sleeve top is not cooled.
Model utility content
The purpose of this utility model is to provide a kind of casting engine of boat and ship cylinder sleeve, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technological scheme:
A kind of casting engine of boat and ship cylinder sleeve, comprise the cylinder sleeve main body of casting, lower projection and gas port is provided with below described cylinder sleeve main body, the pullover of casting is provided with above described cylinder sleeve main body, described pullover in be provided with cooling channel and cooling liquid is imported and exported, described cooling liquid is imported and exported and is located at pullover upper end, and described cooling channel communicates with each other, and described pullover outer surface is provided with groove.
As further program of the utility model: described pullover be tube-in-tube structure, be welded on above cylinder sleeve main body.
As further program of the utility model: described cooling channel is loop configuration, annular cooling channel is imported and exported with cooling liquid and is communicated with.
As further program of the utility model: described pullover upper end is provided with convex shoulder, be provided with cooling liquid inside described convex shoulder and import and export.
As further program of the utility model: described lower projection outer surface is provided with installation groove.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, by the cover header structure of casting, make cylinder sleeve top also can to effectively cool, cylinder sleeve operationally better can be dispelled the heat, adds working life.
Accompanying drawing explanation
Fig. 1 is the structural representation of casting engine of boat and ship cylinder sleeve.
In figure: cylinder sleeve main body 1, pullover 2, cooling liquid import and export 3, cooling channel 4, convex shoulder 5, groove 6, gas port 7, lower projection 8.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, in the utility model embodiment, a kind of casting engine of boat and ship cylinder sleeve, comprise the cylinder sleeve main body 1 of casting, lower projection 8 and gas port 4 is provided with below cylinder sleeve main body 1, pullover 2 of casting are provided with above cylinder sleeve main body 1, be provided with cooling channel 4 in pullover 2 and import and export 3 with cooling liquid, cooling liquid is imported and exported 3 and is located at pullover 1 upper end, cooling channel 4 communicates with each other, pullover 2 outer surfaces are provided with groove 6, pullover 2 is tube-in-tube structure, be welded on above cylinder sleeve main body 1, cooling channel 4 is loop configuration, the cooling channel 4 of annular is imported and exported 3 with cooling liquid and is communicated with, pullover 2 upper ends are provided with convex shoulder 5, be provided with cooling liquid inside convex shoulder 5 and import and export 3, lower projection 8 outer surface is provided with installation groove.The utility model structure is simple, by the cover header structure of casting, make cylinder sleeve top also can to effectively cool, cooling liquid is imported and exported 4 by cooling liquid and is entered cooling channel 3, cooling cylinder cover top, cylinder sleeve operationally better can be dispelled the heat, add and make working life cylinder sleeve operationally can better dispel the heat, add working life.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any reference character in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this specification is described according to mode of execution, but not each mode of execution only comprises an independently technological scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should by specification integrally, and the technological scheme in each embodiment also through appropriately combined, can form other mode of executions that it will be appreciated by those skilled in the art that.
