Summary of the invention
The object of the invention is to the machine oil overcome in existing cast aluminum sump and pass to oil sump by heat, then pass to environment by oil sump, and then dispel the heat, because of the factor such as oil sump heat diffusion area is limited, radiating efficiency is not high.Weak heat-dissipating, the defect that oil return is obstructed, and a kind of marine diesel engine cast aluminum sump machine oil cooling scheme is provided, greatly can improve radiating efficiency, oil return unobstructed control oil sump inner engine oil temperature.
Technical solution of the present invention is such, a kind of marine diesel engine cast aluminum sump, comprise oil sump, heat dissipating pipe assembly, exterior seal ring, inner seal ring and cover plate, it is characterized in that heat dissipating pipe assembly (2) is arranged in oil sump (1) inner chamber, heat dissipating pipe assembly (2) has water intake and water outlet, heat dissipating pipe assembly (2) is equipped with heat dissipating pipe, mounting plate, multiple Duct fixing clamp, and by being welded to connect, cover plate (5) is oil sump (1) and the connection tie of heat dissipating pipe assembly (2), the sealing of outside screw and internal heat dissipating pipe assembly (2) mounting hole is by processing twice groove and the exterior seal ring (3) adopting two O RunddichtringOs, inner seal ring (4) seals, cover plate (5) bolt is arranged on oil sump (1), heat dissipating pipe assembly (2) is installed on cover plate (5) by 2 bolts, heat dissipating pipe assembly (2) has multiple spot to be fixed on oil sump (1) inner chamber, heat dissipating pipe assembly (2) water intake is connected cover plate (5) with water outlet by the mounting hole of oil sump (1) side, exterior seal ring (3) is had between it, inner seal ring (4) seals.
Outside the water intake that exterior seal ring (3), inner seal ring (4) are contained in cover plate (5) and water outlet.
The heat dissipating pipe of heat dissipating pipe assembly (2) is protruding from oil sump (1) mounting hole, is transition fit between it.
the sealing of heat dissipating pipe assembly (2) is by cover plate (5) having inner sealing groove and inner seal ring (4) sealing.
The sealing of cover plate (5) installation direction is by the outside seal groove on cover plate (5) and exterior seal ring (3) sealing.
Compared with prior art, the invention has the beneficial effects as follows: traditional cast aluminum sump inner engine oil is dispelled the heat by natural radiation, oil sump increases rib and can improve radiating efficiency, but can limited space be increased.This programme carries out pressure cold oil drain pan inner engine oil by extracting seawater, greatly can improve radiating efficiency, very effective to reduction oil sump inner engine oil temperature.
Accompanying drawing explanation
Fig. 1 is assembling exploded perspective view of the present invention.
Fig. 2 is cover plate for sealing part schematic front view of the present invention.
Reference character: oil sump (1), heat dissipating pipe assembly (2), exterior seal ring (3), inner seal ring (4), cover plate (5).
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
Embodiment 1, and 1) working principle: each Assembly of the parts explosive view of oil sump parts is shown in Fig. 1 (not embodying construction bolt), primarily of oil sump (1), heat dissipating pipe assembly (2), exterior seal ring (3), inner seal ring (4), cover plate (5) composition.Heat dissipating pipe assembly (2) has water intake and water outlet, enclosed water paths is formed in oil sump (1), externally connected pipe and motor-drive pump, take out seawater by motor-drive pump and enter that heat dissipating pipe assembly (2) is inner to circulate, between heat dissipating pipe maritime interior waters and oil sump (1) inner engine oil, the temperature difference is large, coefficient of heat transfer is high, can take away machine oil amount of heat, and then reduces oil temperature.
2) annexation and each part main points: this oil sump assembly, as an assembly unit, first should assemble each sub-part, then be installed on motor.Oil sump (1) need process for by the tapped hole of the hole of heat dissipating pipe assembly (2), fixing heat dissipating pipe assembly (2) and install cover plate (5) tapped hole.Heat dissipating pipe assembly (2) is answered integrated heat dissipation pipe, mounting plate, multiple Duct fixing clamp, by being welded to connect.Cover plate (5) is as the connection tie of oil sump (1) with heat dissipating pipe assembly (2), realize the sealing of outside screw and internal heat dissipating pipe assembly (2) mounting hole, by processing twice groove, adopt two O shape rubber seal exterior seal ring (3), inner seal ring (4) seals, cover plate (5) attachment face structure is shown in Fig. 2.Cover plate (5) is first installed and oil sump (1) by many (4 ~ 6) bolts, sealing to construction bolt direction is realized by the outside seal groove on cover plate (5) and exterior seal ring (3), heat dissipating pipe assembly (2) is installed on cover plate (5) by 2 bolts, sealing to heat dissipating pipe installation direction is realized by the inner sealing groove on cover plate (5) and inner seal ring (4), simultaneously, for preventing vibration, heat dissipating pipe assembly (2) carries out many places and is fixed on oil sump (1).
Embodiment 2,1) oil sump inner engine oil radiating mode: for marine diesel engine, get seawater and cool oil sump (1) inner engine oil, this mode is easy to realize, and for the cooling of oil sump (1) inner engine oil, to reduce oil sump inner engine oil temperature very effective.
2) design proposal: this programme adopts cover plate (5) as connecting tie, instead of employing heat dissipating pipe assembly (2) is directly installed on the mode on oil sump (1), its object is to: 1, when satisfied energy realizes installation and space outerpace is limited, increase heat dissipating pipe surface area to greatest extent and can improve radiating efficiency; 2, when oil sump (1) size is certain, the size of the upper mounting hole that can process of oil sump (1) is restricted.Directly install and the mode on oil sump (1) according to heat dissipating pipe assembly (2), heat dissipating pipe need stretch in oil sump (1) from outside and install, because the hole size that oil sump (1) is processed is limited, length and the surface area of heat dissipating pipe are restricted, and this programme is by increasing cover plate (5), heat dissipating pipe assembly (2) can be realized install from protruding in oil sump (1), therefore oil sump (1) is as long as the hole of upper processing can make heat dissipating pipe attachment face pass through, oil sump (1) interior space can be utilized to greatest extent, increasing heat radiation area.
