Problems solved by technology
The volume of the oil sump of the existing marine medium-speed diesel engine cannot carry the amount of lubricating oil that meets its operating requirements, so it cannot be directly applied to the heavy-duty medium-speed diesel engine for nuclear power emergency generators
At the same time, since the existing drawings do not have an installation plan for the lubricating oil pump of the engine, the installation of the lubricating oil pump of the main engine needs to be considered when designing the oil pan
[0004] The oil pan is the main container for the diesel engine to store lubricating oil. If the supply of lubricating oil is interrupted, it will not only affect the normal operation of the diesel engine, but in severe cases, the whole diesel engine will be scrapped

Embodiment Construction
[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings.
[0027] As shown in the figure, the heavy-duty medium-speed diesel engine wet sump for the nuclear power emergency generator of the present invention includes:
[0028] The oil sump 2 is provided with three support plates 5 in the oil sump 2. The support plates 5 are of a "π" type structure and are cut from 5mm steel plates, which are evenly distributed inside the oil sump 2, and are connected with the oil sump. The bottom plate and the side plate of the shell 2 are connected by welding. Its function is to enhance the strength and rigidity of the oil pan and prevent it from excessive deformation.
[0029] A free end plate 3 is arranged at the free end of the oil pan 2 . A flange interface is reserved at the upper left position of the free end end plate 3 for installing the main lubricating oil suction flange 16, and the main lubricating oil suction flange 16...

A heavy medium-speed diesel engine wet oil sump for a nuclear power emergency generator comprises an oil sump shell defined by a bottom plate and side edges, a main lubricating oil suction pipe with a one-way valve, a main lubricating oil suction opening filter screen body, a pre-supply oil pump suction pipe and a pre-supply oil suction opening filter screen body. Multiple support plates are arranged in the oil sump shell. The support plates are connected with the bottom plate and the side edges in a welded manner. By the adoption of the heavy medium-speed diesel engine wet oil sump for the nuclear power emergency generator, the use requirement of the nuclear power emergency generator unit can be completely met, and meanwhile a simple and feasible scheme is provided for mounting of a diesel engine main lubricating oil pump.
Description
technical field [0001] The invention relates to the field of mechanical manufacturing of nuclear power emergency generators, in particular to a heavy-duty medium-speed diesel engine wet oil pan for nuclear power emergency generators. Background technique [0002] In recent years, with the rapid development of my country's nuclear power industry, the demand for emergency generator sets for nuclear power has also increased year by year. As one of the core components of nuclear power emergency generator sets, the demand for heavy-duty medium-speed diesel engines is also growing simultaneously. [0003] Due to the special requirements of the nuclear power emergency generator set, it is required that the generator set can run continuously for at least seven days without failure after it is started. The existing marine medium-speed diesel oil sump volume cannot carry the amount of lubricating oil that meets its operating requirements, so it cannot be directly applied to heavy-dut...
