Volvo diesel generator unit operation precautions

One. Preparation work before the generator is used

1. Disconnect the high-voltage switch in the distribution room and switch the isolation switch to the generating position.

2. Switch the isolation switch in the generator room to the generating position.

3. Before starting, check whether the fuel tank is sufficient, and whether there is oil leakage at the oil pipes and joints; Check whether the cooling system has enough water, is clean and does not leak, whether the fan belt is tight, check whether the internal combustion engine is reliably connected to the transmission part of the generator, whether the output circuit wire is well insulated, and whether the instrument is complete and effective.

4. Check whether the connectors, fasteners and operating parts are loose, falling off and stuck, and whether the connection of each wire is firm, correct and in good contact.

5. Open the control cabinet under the generator operation screen, close the start switch, and wait for the display to be powered on. Press the page turning button to view the relevant operation records of the generator.

Two, start the generator

1. Press the start button to start the generator. Should run at a low speed for 3 ~ 5 minutes, when the temperature and oil pressure wheel is normal, you can start to work. During operation, the operator closely monitors the indicator and change of the voltage, frequency, current, power factor, oil temperature, oil pressure, water temperature, charging current, speed and other instruments of the generator set through the instrument. When the specified value is exceeded, the operator should check in time and take measures to resume operation after restoring to normal. There should be no mechanical noise in the generator set, no abnormal noise caused by abnormal vibration, good contact between the slip ring and the brush on the commutator, no bounce and spark, stable operation, frequency voltage reaches the rated value, can be connected to the external power supply.

2. The emergency stop button on the control panel is only used in emergency situations. After pressing the button, the generator will stop immediately and send out sound and light alarm at the same time.

3. In case of abnormal sound, peculiar smell, sharp rise of water temperature, sharp drop of oil pressure and other phenomena in operation, the machine should be shut down immediately to check and troubleshoot.

4. The power factor of the generator shall not exceed 0.95 in the later period (lag), and the variation range of the frequency value shall not exceed 0.5HZ.
