In the process of using LED advertising vehicles, occasionally there will be some minor faults in the generator set, resulting in the generator set not working properly. In fact, as long as a slight adjustment can be restored to normal, so we should have the ability to handle simple faults, in the event of a generator set failure, make an adjustment to see if the fault can be resolved. Pay attention to the following aspects when adjusting:
1. Adjusting the regulator: If the generator does not move or the charging current is too large or too small during use, the regulator needs to be adjusted. If the battery is charged, the current is too large to shorten the service life of the battery; if it is too small, the battery cannot be charged on time. When the diesel generator is working, if the charging current indicated by the charging current meter is too large, the current limiting spring of the regulator should be adjusted to shorten the spring, and the current will decrease, otherwise the current will increase. Pay attention to the force during the adjustment process, and touch it gently until it meets the requirements.
2. Adjustment of oil pressure: There are two kinds of lubrication methods for generators: pressure lubrication and splash lubrication. The lubrication quality of the generator has a lot to do with the pressure of the oil. Therefore, the generator must be oiled when working. The pressure is controlled within an effective range.
3. Decompression adjustment of the generator: In the winter, during the use of the generator, it may be difficult to start due to cold weather or insufficient battery power. At this time, the method of decompressing the intake valve of the generator should be adopted to reduce the compression ratio, improve the starting resistance, and start the generator.
4. Adjustment of the fan belt: The tension of the fan belt of the generator should be just right. If it is too tight, the wear of the straight alternator bearing, the water pump bearing and the fan bearing will be intensified. If the belt is too loose, the fan will have insufficient air volume, which will affect the cooling effect of the cooling water. At the same time, the generator output voltage will drop and the pump flow will decrease. To the use requirements. Therefore, it is necessary to adjust the fan belt according to the requirements of use.
