The Phenomenon That the Performance of Volvo Generator is Declining

After Volvo diesel generator has been used for a long time, regular maintenance is required. If the user ignores this point, the performance of Volvo generator may gradually decline, and the performance decline of the generator set may bury a major hidden trouble and make it enter the overhaul ahead of schedule. period, shorten the service life, when your diesel generator set has the following phenomena, you need to pay attention. 

1. The oil pressure is reduced. During the normal operation of the diesel generator set, the wear of the bearing can be judged by the oil pressure. The lower the oil pressure, the larger the bearing wear clearance. 

2. Fuel consumption increases. The increase in fuel consumption is related to many factors. For example, the oil volume adjustment of the fuel injection pump sub-pump is too large, the fuel injection nozzle leaks oil, the cooling effect is poor, the sealing of the intake and exhaust valves is not strict, the quality of the lubricating oil is poor, and the cylinder pressure is too low, which will increase the oil volume of Volvo generator during operation. Therefore, Dingbo Power reminds users that the increase in fuel consumption of diesel generator sets is a comprehensive evaluation index. 

3. The oil consumption increases. As we all know, during the normal operation of the diesel generator set, the increase in oil consumption is mainly reflected in the increase in the wear degree of the cylinder and piston group. The more blue smoke in the exhaust pipe of the diesel generator set, the more oil consumption.

4. The impurities in the oil increase. The number of grams of impurities in the oil judges the wear degree of the lubricating parts required in the diesel generator set. Generator manufacturers remind users that the content of various elements in the oil can also be tested to determine the rate of wear of moving parts. 

5. The crankshaft pressure is reduced. The size of the crankshaft pressure can judge the wear degree of the cylinder liner and piston assembly of the diesel generator set. 

6. The power of the Volvo genset decreases. The maximum power of the diesel generator set is compared with the rated power specified in the technical specification, and the technical conditions of the diesel generator set are compared. During normal use, the degree of power drop of the whole machine can also indicate the degree of wear of parts, such as cylinder liners, pistons, piston rings, etc.

7. The cylinder pressure is reduced. Pressure from diesel to extreme cylinders can tell the extent of leaks in cylinder liners, piston assemblies, intake and exhaust valves and valve seats. 

The above are all signs of the performance degradation of the diesel generator set. Once these phenomena are found, Dingbo Power recommends that a comprehensive maintenance of the diesel generator set must be carried out before continuing to use it to ensure the normal operation of the generator set, and also to ensure the operation of the generator set. life safety of personnel.
