Many customers have a wrong understanding when using and maintaining diesel generator sets. They think that if the generator is not often used, it does not necessarily need to be maintained. Only when it is used more and for a long time, it needs to be maintained.
Whether the diesel generator set is used or not, it must be maintained regularly, especially because the first 60 hours of the diesel generator set is the run-in period. After the run-in period, the lubricating oil in the generator set contains a large amount of iron and slag, which seriously pollutes the lubricating oil. Such contaminated lubricating oil to lubricate the generator set again will only cause serious damage to the engine. Moreover, the lubricating oil also has a shelf life. Once the lubricating oil is expired, it will not lubricate the engine, but because the expired lubricating oil becomes sticky and blocks the lubricating oil channel to damage the engine.
There is a long-term do not check the replacement of the diesel generator filter, (air filter, diesel filter, oil filter) not only affect the power of the diesel generator, but also because of the blockage of the filter element to the engine failure left hidden trouble.
The normal maintenance of diesel generator is not only a simple replacement of lubricating oil and filter element, but also a comprehensive and systematic inspection of the generator to remove hidden problems of diesel generator sets and eliminate faults in the bud. In this way, regular periodic maintenance of the diesel generator set can ensure the normal service life of the generator set.
The purpose of,
Ensure the sound and safe operation of diesel generator set, ensure that in the mains power failure can be put into use in time, to ensure normal power supply.
Two, the scope of application
(a) regular maintenance of diesel generator sets
1. Check the water level and oil level once a day;
2. Clean the external surface of the unit and the environment of the machine room once a day.
(2) diesel generator set maintenance at the end of the month
1. Clean the external surface of the unit;
2. Check whether the speed regulating rod is flexible and lubricates each connection point;
3. Replace the cooling water, measure the PH value (normal value 7.5-9) before and after the replacement, and make a good measurement record, and apply medicine if necessary (notify the water treatment workers to cooperate);
4. Check the tension of the fan belt and the charger belt, and adjust it if necessary;
5. Cooperate with the emergency power generation test of electrical work to check whether the reading, temperature and loudness of each instrument are normal when the diesel engine is running, and make a good operation record.
(3) diesel generator set maintenance at the end of the month
1. Check the air flow resistance indicator and clean the air filter when it is red;
2, release diesel water, clean grade diesel filter;
3, it is necessary to pay attention to lubrication fan belt pulley and belt tensioning wheel bearings;
4. Check the lubricating oil level of the overspeed mechanical protection device, and add oil when insufficient;
5. Check the fastening of the main external connecting bolts.
(4) annual maintenance of diesel generator sets
1. Cooperate with electricians to carry out parallel load operation and check the operation situation;
2. Cooperate with electrical simulation to test the performance of each safety protection device;
3. Test and check the axis and opening gear, and make good records;
4. Remove the inspection cover to observe the inspection shaft and cylinder;
5. Dosing and cleaning the cooling system (notify the water treatment worker to cooperate);
6. Check the quality of oil and replace the oil when necessary;
7. Clean the second level diesel filter;
8. Clean the oil filter;
9. Add the following items after every 500 hours of operation:
A. Replace the filter element of the second stage diesel filter;
B. Change the oil;
C. Check the tightness of cylinder head bolts and connecting rod bolts;
D. Check and correct valve clearance, timing and record oil injection;
E. Pressure test and adjustment of fuel injector.
