Description
Technical Field
The invention relates to a marine diesel engine, in particular to a diesel engine oil pan cooling device.
Background
The internal combustion engine is an important power machine and is widely applied to various fields of industrial production and social life. Among them, diesel engines are an important branch of internal combustion engines, and have an irreplaceable position in terms of power of transportation means, agricultural machines and engineering machines.
The oil pan has the functions of preventing other impurities from entering the closed crankcase, collecting and storing lubricating oil flowing back from between each kinematic pair of the diesel engine, dissipating part of heat and preventing the lubricating oil from oxidative denaturation.
With the continuous improvement of the strengthening degree of the engine, the heat load is higher and higher, so that the lubricating effect of the engine is influenced due to the fact that the temperature of lubricating oil is too high, and the dynamic economy, the reliability and the like of the engine are influenced due to lubrication failure.
In the oil pan of a diesel engine, hot lubricating oil is concentrated in an upper layer due to the reduction of the density of the temperature rise, and cold oil is concentrated in a lower layer, and the cooling device of the existing oil pan of the diesel engine is concentrated only in the lower part of the oil pan of the diesel engine to cool the lubricating oil in the oil pan effectively. The hidden trouble caused by the too high temperature of the lubricating oil still exists.
Disclosure of Invention
The invention aims to provide a low-speed engine oil pan reinforced cooling device for a ship, which has strong universality and remarkable cooling effect.
The purpose of the invention is realized in the following way:
the invention relates to a low-speed engine oil pan reinforced cooling device for a ship, which is characterized in that: including the oil pan, set up the oil inlet on the outer wall of oil pan upper end, set up the oil drain port on the outer wall of oil pan lower extreme, set up the cooling water pipeline in the oil pan, the cooling water import of cooling water pipeline is located the outside of oil pan one side, the cooling water export of cooling water pipeline is located the outside of oil pan opposite side, the cooling water pipeline is located the bottom surface inner wall of oil pan, set up cooling water pipe annular rib on the outer wall of cooling water pipe, the bottom surface inner wall of oil pan sets up reinforces heat transfer recess.
The invention may further include:
1. the bottom of the oil pan is provided with a diversion turbine which guides the upper layer of lubricating oil into the lower part of the oil pan and sends the lower layer of lubricating oil to the upper part.
2. The upper part of the oil pan is provided with a wind wave prevention baffle along the longitudinal direction of the oil pan.
The invention has the advantages that:
1. the new diversion turbine is added, so that the hot lubricating oil can be effectively cooled. The current situation that the upper layer of the hot lubricating oil cannot be cooled and the lower temperature lubricating oil is cooled at the bottom in the existing cooling mode is avoided.
2. Annular ribs are arranged outside the water cooling pipeline, equipment is not added in a limited space, and heat exchange is effectively enhanced.
3. The grooves of the bottom plate of the oil pan are arranged, so that the lubricating oil at the bottom of the oil pan can be cooled by surrounding air.

FIG. 2 is a schematic view of an oil pan with a inducer turbine;
fig. 3 is an overall schematic of the present invention.
Detailed Description
The invention is described in more detail below, by way of example, with reference to the accompanying drawings:
referring to fig. 1-3, the low-speed oil pan reinforced cooling device for a ship mainly comprises: the oil inlet 1, the oil drain port 2, the cooling water inlet 3, the cooling water outlet 4, the wave-resistant ring groove 5, the oil pan reinforcing rib 6, the oil pan bolt hole 7, the flow guiding turbine 8, the reinforced heat exchange groove 9 and the cooling water pipe annular rib 10.
The upper part of the oil pan is provided with a wind wave prevention baffle plate 5, and the floor of the oil pan is provided with a reinforced heat exchange groove 9 which are mutually combined to prevent the lubricating oil in the oil pan from tilting and leaking due to the jolt of the wind waves on the sea.
The rectangular groove 9 at the lower part of the oil pan is a fin for heat exchange between the lower part of the oil pan and air, so that the heat convection and radiation exchange between the lower bottom plate of the oil pan and the air are enhanced.
The water cooling pipeline at the lower part of the oil pan reasonably utilizes sea water for heat exchange, and a circle of annular ribs are additionally arranged outside the heat exchange pipeline, so that the heat exchange between the water cooling pipeline and the lubricating oil is enhanced.
According to the invention, two diversion turbines are arranged at the bottom of the traditional diesel engine oil pan, and the two turbines are used for guiding the lubricating oil with higher temperature at the upper layer in the oil pan into the lower part of the oil pan for concentrated cooling, and then the lubricating oil with cooled lower layer of the oil pan is sent to the upper layer of the oil pan.
According to the invention, the design of the bottom plate of the traditional oil pan is modified, a plurality of grooves are formed in the bottom plate at the bottom of the oil pan, and the grooves are added, so that the liquid level in the oil pan is deepened, and the lubricating oil loss caused by shaking and overflowing of the lubricating oil in the oil pan due to seaborne storms is prevented. In addition, the grooves form heat dissipation ribs on the outer side of the oil pan bottom plate, so that the oil pan bottom plate can dissipate heat by means of surrounding air.
In order to achieve the effect of enhancing heat exchange, besides the measures, the invention also provides a seawater cooling water pipeline at the bottom of the oil pan, and annular ribs are arranged outside the cooling water pipeline to enhance heat exchange between cooling water and hot lubricating oil.
As shown in fig. 3, the hot oil enters the oil pan from the oil inlet 1, and is then sucked into the bottom of the oil pan by the guide turbine 8. The hot oil is cooled at the bottom of the oil sump by a cooling water channel with annular ribs 10 together with rectangular grooves 9 in the bottom of the oil sump. Cooling seawater enters from the cooling water inlet 3, and after cooling, the lubricating oil flows out from the cooling water pipeline 4. The cooled oil flows out from the oil drain port 2.
The specific principle of the invention is as follows:
the lubricating oil with higher temperature is accumulated on the upper layer of the oil pan due to lower density, so that the effective cooling of the cooling device positioned on the oil pan can not be obtained.
