Marine Diesel Generating Set Turbocharger Overload Overheat

Jan. 13, 2022

In the process of using marine diesel generator set, we encounter the phenomenon of turbocharger overheating. What's going on? Dingbo power introduction: the phenomenon of long-time overload of marine diesel generator and low oil pressure will lead to overheating of turbocharger!


1.Causes of overheating of turbocharger of marine diesel generator set.


If the generator is overloaded for a long time, it will cause poor fuel combustion and high exhaust temperature, which will correspondingly increase the local overheating of the turbocharger, resulting in dull noise and black smoke from the exhaust pipe.


Low oil pressure.

On the one hand, it will cause insufficient lubrication of the turbocharger friction surface, accelerate wear, improve the bearing clearance and greatly deteriorate the lubrication


On the other hand, it will not only lead to insufficient cooling of the turbocharger and the increase of overspeed temperature rate, but also reduce the viscosity of the oil and further deteriorate.


Engine oil deterioration and improper adjustment of cooling water temperature (full load within 93 ℃) are also the reasons for turbocharger overheating.

2.Countermeasures


Precautions for reducing turbocharger failure of marine diesel generator set


1. Judge the working state of large Yuchai generator set (vibration, noise, exhaust color, water leakage, etc.) in strict accordance with the operating procedures and inspection of working state, so as to provide clues for finding faults;


2. Do maintenance work and follow the maintenance plan.


3. Grasp the characteristics, hazards and corresponding disposal methods of faults to reduce serious accidents.


4. The fault shall be eliminated in time, and the diesel engine shall not be started until the problem is solved, so as to avoid further damage.


The above are the causes and solutions of overheating of turbocharger of marine diesel generator set introduced to users by Dingbo power, hoping to bring reference to users.


When troubleshooting the cause of turbocharger overheating, the following contents shall be strictly followed:


1. Accurately judge the working state of diesel engine (vibration, noise, exhaust color, water leakage, etc.) in strict accordance with the operating procedures and inspection of working state, so as to provide clues for finding faults;


2. Do maintenance work and follow the maintenance plan.


3. Grasp various characteristics, hazards and corresponding disposal methods of faults to avoid serious accidents.


4. The fault shall be eliminated in time, and the diesel engine shall not be started until the problem is solved, so as to avoid further damage.
