Marine diesel engine is an important part of Marine power system, its running state directly affects the safety and economic benefits of the ship. As an important part of diesel engine, the maintenance and repair technology of diesel engine forging is very important to the normal operation of diesel engine. This paper introduces the repair and maintenance technology of Marine diesel engine forgings.
Maintenance technology of Marine diesel engine forgings
Fault diagnosis
Fault diagnosis is the first step in the maintenance process. By observing the working state of the diesel engine, listening to the sound, checking the oil pressure, temperature and other parameters, the cause and location of the fault can be preliminarily determined. At the same time, the use of advanced testing equipment, such as vibration analyzer, oil analyzer, etc., can carry out more in-depth fault diagnosis of diesel engine.
Disassembly and inspection
On the basis of fault diagnosis, you need to remove related components for detailed inspection. By observing the wear, deformation, cracks and other conditions of the parts, the maintenance program can be determined. At the same time, the relevant parts are measured and tested to ensure that their performance meets the requirements.
Repair and replacement
Repair or replace damaged parts according to inspection results. For slightly worn parts, grinding, polishing and other methods can be used to repair; For severely worn or damaged parts, replace them with new parts. During the repair and replacement process, pay attention to the installation position, fitting accuracy, and connection firmness of the parts.
Debugging and trial run
After the repair or replacement is completed, the diesel engine needs to be commissioned and trial run. By adjusting the parameters, the diesel engine can be restored to normal working state. At the same time, observe the running condition of the diesel engine to check whether there are abnormal sound, vibration and other problems. If all is well, it can be delivered.

Periodic inspection
Check the diesel engine regularly, including appearance, internal structure, oil, etc. By checking visually or using detection devices, you can find potential problems in time and avoid faults.
Cleaning and lubrication
Keeping the diesel engine clean and lubricated is an important part of maintenance. Regularly clean the appearance and internal parts of the diesel engine to remove dust and dirt; Replace oil, hydraulic oil and other lubricating oil regularly to ensure the normal lubrication of each component.
Adjustment and fastening
Various parameters of diesel engine are adjusted, such as valve clearance, injection advance Angle, etc., to ensure its normal operation. At the same time, the connection of each component is tightened to ensure that the connection is firm and stable.
Preventive maintenance
Preventive maintenance is an important means to avoid failure. By regularly replacing worn parts, cleaning filters and other measures, the probability of failure can be reduced. At the same time, the diesel engine is recorded for preventive maintenance, so that potential problems can be detected and dealt with in time.
The repair and maintenance technology of Marine diesel engine forgings is very important to ensure the normal operation of diesel engine. Through reasonable maintenance technology and maintenance measures, the service life of diesel engine can be extended, and its operating efficiency and economy can be improved. Therefore, crew and maintenance personnel need to fully understand and master these technologies to ensure the safety and economic efficiency of the ship.
