Description

Technical Field

[0001] The invention relates to the technical field of marine diesel engines, and in particular to an exhaust pipe bracket device of a medium-speed diesel engine and a mounting method thereof. Background Art

[0002] The diesel engine's supercharging system is used to increase the amount of air entering the diesel engine's combustion chamber. The fresh air is filtered through the air filter, compressed by the supercharger compressor, cooled by the intermediate air cooler, and then distributed to each cylinder through the cast aluminum intake manifold. The exhaust gas after combustion and work flows into the exhaust pipe through the exhaust manifold, driving the supercharger turbine, and the turbine drives the compressor impeller.

[0003] Due to the redesign of the supercharging system of a medium-speed diesel engine, in order to improve the smooth flow of the exhaust pipes of each cylinder and ensure that the exhaust gas continuously provides kinetic energy for the supercharger, the supercharger exhaust pipe was redesigned. Since the exhaust pipe is affected by the diesel engine body and the airflow in the pipeline during the operation of the diesel engine, it will produce greater vibrations. The vibration will reduce the service life of the exhaust pipe and easily cause rupture and breakage of the fixing bolts, which will affect the normal operation of the diesel engine.

[0004] In addition, if the exhaust pipe ruptures or the fixing bolts break, high-temperature gas will leak from the pipeline, which may easily injure people.

[0005] Therefore, it is necessary to provide a new exhaust pipe bracket device for a medium-speed diesel engine and an installation method thereof to solve the above-mentioned technical problems. Summary of the invention
