During the operation of diesel generator sets, the monitoring of each subsystem by the operators is directly related to the power supply quality of the diesel generator sets. Therefore, the management regulations for diesel generator sets must be earnestly implemented. Below, Beidou Power briefly introduces the monitoring methods for each subsystem of diesel generator sets.
Monitoring of the operating system
The floating value of the generator’s output current frequency must be within the specified range. If the fuel supply handle jumps or slides due to long-term power supply, it will cause unstable diesel engine speed and affect the output current frequency. Therefore, after the operator adds load to the unit, they must lock the fuel supply handle at the rated speed position.
2. Management of the fuel supply system
The physical shape of the components of the diesel engine fuel supply system. During the operation of the diesel generator set, it is necessary to ensure that the diesel is clean, free of impurities and leakage, and no air is allowed in the system.
When impurities in diesel clog each filter screen, it will cause the fuel supply of the diesel engine to be interrupted or insufficient. Therefore, such a situation is strictly prohibited during operation. When a diesel engine is operating at its rated speed, if there is oil leakage at each interface, the fuel injection pump or the fuel transfer pump, or if air is mixed in the fuel supply system, it will cause a decrease in the power of the entire diesel generator set and unstable frequency, etc.
3. Management of the lubrication system
The management of the lubrication system is generally carried out from three aspects: oil pressure, oil temperature and oil quality.
During the operation of the diesel generator set, it is necessary to frequently observe and check the indication of the oil pressure gauge and the oil dipstick on the oil pan. This is because when the diesel generator set is running at high speed, if the cylinder gasket of the diesel engine is damaged or the water-cooled oil radiator is damaged, the cooling water will enter the oil pan, causing the oil level to rise and the oil to deteriorate. If the operator fails to detect the above situation in time, the diesel engine will experience a bearing seizure accident. In severe cases, it may even lead to the connecting rod breaking the engine block, causing undue and significant economic losses. Therefore, during the operation of the diesel generator set, the operator should draw out the oil dipstick from time to time for inspection. When a fault is found, the machine should be stopped immediately for handling.
