A diesel generator set is a small and independent power generation device. It has the advantages of flexibility, low investment and the ability to start at any time. It is widely used in telecommunications, mining, road construction, forestry, agricultural irrigation, field engineering, construction and defense sectors. In AC power supply equipment, diesel generator sets are essential power generation devices for self-owned power plants. The start-up of a diesel generator set should follow the correct procedures. Let’s take a look at the correct start-up steps for a diesel generator set.
Loosen the air release screw on the fuel injection pump, use the fuel hand pump to expel the air in the fuel system, and at the same time fix the adjustment control handle at the throttle position suitable for the starting speed.
2. Press the start button to start the diesel engine. If the diesel engine still cannot start after 10 seconds (up to 15 seconds), wait for 1 minute and then try to start it again. If it still cannot start after three consecutive attempts, check and find out the cause of the fault.
After the diesel engine starts, pay close attention to the reading of the oil pressure gauge (2.5-3.5kg/ cm ² during normal operation). If the oil pressure gauge does not indicate, stop the machine immediately for inspection and check whether the ammeter indicates charging.
After the unit starts, gradually increase the no-load speed to 1000-1200r/min (note that it should not run at low speed for a long time). After the preheating process of the diesel engine, increase the speed to the rated speed. Full-load operation is only allowed when the outlet water temperature reaches 55℃ and the engine oil temperature reaches 45℃.
5. When all the instruments of the unit indicate normally, the load switch can be closed to supply power to the load. As the load of the unit changes, if the frequency and voltage are not within the specified range, they should be adjusted in time to maintain the rated values. It is strictly prohibited for the unit to operate under load at low speed to avoid damaging the equipment.
After the unit is put into normal operation, it is necessary to pay close attention to the changes in water temperature, oil temperature and oil pressure, as well as the readings of the power meter, frequency meter, ammeter and voltmeter at all times. Any abnormality should be dealt with promptly.
