Heavy medium-speed diesel engine wet sump and design method thereof

Abstract

The invention discloses a heavy medium-speed diesel engine wet sump which comprises an oil sump body (7), a timing gear end cover plate (6), an output end cover plate (9), a pre-supply oil pump suction port (4), an oil separator suction port (5), an oil separator oil return port (3) and a lubricating oil pump oil suction device, wherein a plurality of oil sump support plates (8) are arranged in the oil sump body (7); the timing gear end cover plate (6) and the output end cover plate (9) are respectively located at two ends of the oil sump body (7); the pre-supply oil pump suction port (4) is formed in the bottom of the timing gear end cover plate (6) for connecting with a pre-supply lubricating oil pump; the oil separator suction port (5) is formed in the bottom of the timing gear end cover plate (6) for connecting with an oil separator;, the oil separator oil return port (3) is formed in the bottom of the output end cover plate (9) for connecting with the oil separator; and the lubricating oil pump oil suction device is located at the bottom of the oil sump body (7) for providing lubricating oil for a diesel engine. The invention also discloses a design method of the heavy medium-speed diesel engine wet sump. The wet sump, disclosed by the invention, has the advantages of complete function, reasonable structure, reliable strength and good seal.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a heavy-duty medium-speed diesel engine wet oil pan and a design method thereof. Background technique [0002] With the continuous expansion of the business scope of Chinese shipping companies, there are more and more different customer needs, resulting in a rapid replacement of new and old models, and there are many models. Different oil pans are required for different machines. The oil sump of the old model has the following disadvantages: Due to the special requirements for the use of heavy-duty medium-speed diesel engines for nuclear power emergency generators, it is necessary for the diesel engine to run continuously for at least 7 days without failure after it is started. The volume of the existing diesel oil pan cannot carry the amount of lubricating oil that meets its operating requirements. Moreover, the flow area of ​​the piping system of the oil suction device...

AI Technical Summary

Problems solved by technology

The oil pan of the old model has the following disadvantages: Due to the special requirements for the use of heavy-duty medium-speed diesel engines for nuclear power emergency generators, it is necessary for the diesel engine to run continuously for at least 7 days without failure after starting

Existing diesel engine oil sump volume cannot carry the amount of lubricating oil that meets its operating requirements

Moreover, the flow area of ​​the piping system of the lubricating oil pump oil suction device of the old model cannot meet the lubricating oil flow requirements of the heavy-duty medium-speed diesel engine used in nuclear power emergency generators

[0003] Therefore, it cannot be directly used for the wet oil sump of heavy-duty medium-speed diesel engines used in nuclear power emergency generators
