When marine diesel generator sets are used in different seasons, the following aspects should be paid attention to to to ensure their stable operation and prolong their service time:After screening and investigation marine generator It is likely to become a new force driving economic development. https://usrpower.com/product-category/marine-generators/pmg-yacht-generator/
A, marine diesel generator set preparation before the season.
Sanitary cleaning of marine diesel generator set;
Remove the insulation blanket (if applicable) and thoroughly clean the generator set, including cleaning up dirt, sundries, grease, etc.
In the process of cleaning, pay attention to check loose nuts, rivets and appearance defects, and replace and repair them in time.
Check and change the oil:
According to the requirements of the instruction manual of the generator set, select the engine oil suitable for the current season.
Drain the old oil and replace it with new oil and oil filter.
Check and replace the third filter of marine diesel generator set;
Air filter, diesel filter and oil filter (referred to as “three filters” for short) are important parts of the generator set and need to be inspected and replaced regularly.
Paper filter may not fully recover its performance after cleaning, so it is recommended to replace it with a new one. Metal filter screen and filter element can be cleaned with clean oil, brush or air cylinder, but not with fire.
Check the cooling system:
Check the level and quality of coolant and replace it if necessary.
Clean the scale and sediment in the cooling system to ensure good cooling effect.
Second, the marine diesel generator set in season when the operation of the matters needing attention
Adjust the oil indicator:
For diesel engines equipped with “winter and summer” rotation indicators, the arrow of the indicator should be rotated to the word “summer” to realize large oil circulation, so as to reduce the pressure drop and parts wear caused by excessive oil temperature.
Use the right fuel:
According to the seasonal changes, choose the fuel suitable for the current temperature. When the temperature is high in summer, low viscosity fuel such as No.0 diesel can be used to reduce fuel consumption and carbon deposition.
Start and run the check:
Before starting the marine diesel generator set, check whether the liquid levels of fuel, lubricating oil and coolant are normal.
After start-up, observe the operating conditions of the generator set, such as whether the parameters such as voltage, frequency, oil temperature and water temperature are within the normal range.
If any abnormality is found, stop the machine immediately to check and troubleshoot.
Three, marine diesel generator set after the season maintenance.
Regular inspection and maintenance:
According to the usage of the generator set, check and maintain the plan regularly.
Check whether cables and connectors are fastened and reliable, check brushes and carbon deposits, and make necessary cleaning and replacement.
Storage management:
If the generator is not used for a long time, it should be stored in a dry, ventilated and dust-free environment to avoid direct sunlight and humidity.
Close the fuel valve and cooling water valve, remove the battery and keep it properly.
Recording and feedback:
Record the usage and maintenance records of the generator set, so as to find and solve problems in time.
If the generator set is found to be faulty or abnormal, it should be stopped in time and seek the help of professionals.
To sum up, marine diesel generator sets need to pay attention to many aspects when they are used in different seasons, including preparations before changing seasons, operational precautions during changing seasons and maintenance after changing seasons. Through inspection and maintenance, it can be ensured that the generator set can run stably and reliably in an emergency.
