Abstract
The utility model discloses a machine body, including cylinder body and cylinder liner, be equipped with the cooling chamber between cylinder body and the cylinder liner, the cooling chamber is cooled off the chamber and is cooled off the chamber down on including corresponding from top to bottom to set up, be equipped with on the cylinder body with the cooling water inlet opening of last cooling chamber intercommunication with be used for the cooling water apopore of last cooling chamber with the inlet channel intercommunication of the cylinder cap of treating the installation, be equipped with on the cylinder body and be used for saying cooling water water return hole and the cylinder body apopore that communicates with the return water of the cylinder cap that cools off the chamber down and treat the installation. The lower cooling water of temperature is whole during the use is used for cooling off earlier the cylinder jacket top, then gets into the cylinder head and cool off, and the cooling water that flows back to from the cylinder head cools off the cylinder jacket bottom, and what make like this that the cooling water can be abundant cools off the cylinder jacket top, has reached the maximize of cooling water rational utilization. Through experimental identification, this kind of cooling method has reached fine cooling effect really, guarantees that the cylinder jacket top can obtain abundant cooling, reduces the trouble incidence of engine.
Description
Technical field
The utility model relates to a kind of body.
Background technique
Along with constantly bringing forth new ideas of diesel technology, its power per liter and torque value improve constantly, simultaneously for meeting the emission regulation demands of increasingly stringent, the pressure of explosion that parts and components of diesel engine bears and thermal stress more and more higher, therefore, the cooling how met under cylinder liner hot environment also becomes a new problem.Existing body adopts the unidirectional direct cooling air cylinder sleeve of circulating water, and as shown in Figure 1, cooling water directly enters the water jacket of body, one-way flow, then flows to cylinder head from the opening at body top and cools.In the prior art scheme, there is following shortcoming in the cooling of cylinder liner:
Cooling water enters water jacket when cooling cylinder liner, no matter be high-order water inlet or low position inflow water, cooling water is almost impartial cooling relation for the part that cylinder liner contacts with water jacket, in fact, in working process of diesel engine, cylinder liner temperature is reduced to temperature of lower successively by top, the cooling at what we were concerned about most is but cylinder liner top, and the cooling relation of this equalization will certainly cause cylinder liner to form a temperature gradient from top to bottom, the existence of this temperature gradient is disadvantageous for the diesel engine of long-term work, cooled fully from another aspect cylinder liner top, part cooling water is had to be underutilized.The long-term high temperature in this cylinder liner top will certainly cause the diesel engine faults such as piston crown carbon distribution, cylinder liner cavitation.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of body that effectively can solve the cooling of cylinder liner top.
For solving the problems of the technologies described above, the utility model comprises cylinder body, cylinder sleeve is separately installed with in multiple mounting holes of cylinder body, cooling chamber is provided with between cylinder body and cylinder sleeve, its structural feature is that described cooling chamber comprises the upper cooling chamber of corresponding setting up and down and lower cooling chamber, described cylinder body is provided with the cooling water water inlet and the cooling water osculum for being communicated with the inlet channel of cylinder cap to be installed by upper cooling chamber that are communicated with upper cooling chamber, and described cylinder body is provided with cooling water backwater hole for being communicated with the backwater road of cylinder cap to be installed by lower cooling chamber and cylinder body osculum.
Described upper cooling chamber is less than the height of lower cooling chamber along mounting hole axis along the height of mounting hole axis.
Described cooling water water inlet and cylinder body osculum are arranged on the homonymy of cylinder body.
Described cooling water water inlet and cylinder body osculum are arranged on the sidepiece of cylinder body.
The outlet of described cooling water osculum and the import of cooling water backwater hole are arranged on the end face of cylinder body, and the import of described cooling water osculum and the outlet of cooling water backwater hole are arranged on the sidepiece of cylinder body mounting hole.
Described cylinder body is provided with cooling water inlet channel and cooling water water outlet, and the import of described cooling water water inlet is communicated with cooling water inlet channel respectively, and the outlet of described cooling water backwater hole is communicated with cooling water water outlet respectively.
Described cooling water inlet channel and cooling water water outlet are arranged on the homonymy also corresponding setting up and down of cylinder body.
After adopting said structure, the utility model cooling chamber is divided into upper and lower cooling chamber, the cooling water that during use, temperature is lower is all first used for cooling air cylinder sleeve top, then enter cylinder head to cool, the cooling water flowed back to from cylinder head cools bottom cylinder liner, it is high a lot of when now the temperature of cooling water enters body than just, be used for bottom cooling air cylinder sleeve so again, relative to cylinder liner top, the requirement of bottom to cooling of cylinder liner is not strict, so just, make cooling water to cool cylinder liner top fully, reach the maximization of cooling water Appropriate application.Prove through test, this kind of type of cooling reaches good cooling effect really, ensures that cylinder liner top can be cooled fully, reduces breakdown in the motor incidence rate.
