Discussion on the Influence of Friction and Wear on the Reliability of Marine Diesel Engines

In view of the impact of friction and wear on the reliability of marine diesel engines, this article discusses the main causes of wear in marine diesel engines when analyzing the specific effects, including the impact of average effective pressure on friction loss, the impact of rotational speed on friction loss, the impact of cylinder number on friction loss, the impact of oil viscosity and cooling system temperature, and the impact of fuel injection pump pressure on friction loss The impact of the number of piston rings on diesel engines. In the analysis and discussion of the impact of friction and wear on the reliability of marine diesel engines, relevant suggestions were proposed for fault diagnosis, such as the application of the following diagnostic techniques: internal machine equipment gear wear fault analysis, bearing melting wear fault analysis, bearing wear deformation fault analysis, bearing pitting peeling fault analysis, diesel engine piston wear fault analysis, etc, And the following measures to avoid wear issues: reasonably reducing the speed of diesel engines, scientifically reducing the number of piston rings, and continuously optimizing the lubrication system.
