Key points of daily inspection and maintenance of Marine generator
Time：2024-03-12
As the core part of the Marine power system, the running state of the Marine generator is directly related to the safe navigation and daily operation of the ship. Therefore, it is very important to test and maintain Marine generator on a daily basis. This paper will elaborate the steps, operation points and precautions of the daily inspection and maintenance of Marine generators, to help readers better grasp the relevant knowledge, ensure the normal operation of generators, and extend their service life.

1. Routine testing steps
Visual inspection
Check whether the generator housing is intact and there are no cracks, deformation or rust.
Check whether the generator terminal is tight, loose or overheated.
Check that the cooling fan and air vent are clean and free of blockage.
Running status check
Start the generator and observe whether the startup process is smooth and whether there is abnormal sound or vibration.
Check whether the output voltage, current, frequency and other parameters of the generator are within the normal range.
Observe the generator temperature indicator to ensure that the operating temperature of the generator does not exceed the specified value.
Lubrication and cooling system inspection
Check the oil level to make sure it is within the normal range and see if the oil is clean.
Check the cooling water system to ensure that the waterway is smooth, no leakage phenomenon, and the cooling water temperature is appropriate.
Second, the main points of operation
Test preparation
Ensure that the testing tools are complete, including multimeters, thermometers, and vibration meters.
Understand the working principle and performance parameters of the generator, so as to accurately judge its operating state.
Detection operation
In the process of testing, the operation procedures should be strictly followed to avoid misoperation or missing test items.
The abnormal situation should be recorded in time and corresponding measures should be taken.
Maintenance measures
According to the use of the generator, regularly change the lubricating oil and clean the cooling system.
Tighten loose terminals and replace damaged parts.
Third, precautions
Safety first
When testing and maintaining the generator, ensure that the generator is shut down and disconnect the power supply.
Observe safe operation procedures and wear protective equipment to prevent electric shock or mechanical injury.
Maintenance cycle
According to the generator operating instructions and ship operation conditions, to establish a reasonable maintenance cycle.
Regular comprehensive testing and maintenance of the generator to ensure its stable, safe and reliable performance.
Record and report
The results of each test and maintenance are recorded in detail, and generator maintenance files are established.
Report the problems found to superiors in time, and make suggestions for improvement.
Through the implementation of the above steps and points, we can effectively carry out daily testing and maintenance of Marine generators to ensure their normal operation and extend their service life. As a Marine engineer, we should always be vigilant and constantly improve our professional level to contribute to the safe navigation and efficient operation of the ship.
