Several considerations for generators

Proper use and maintenance of the generator set can extend the life of the generator set:
Preparations before starting:
1. The computer room operators should abide by the safety operation rules, wear work clothes and insulating shoes, and the crew members should have a clear division of labor;
2. Check whether the anti-railing cover of the flywheel and generator is in good condition;
3. Check the gearboxes, clutches, governors, oil levels, and fasteners, etc., and confirm that they are in good condition and the oil and water temperature is not lower than 20 degrees before starting;
4. Set the gates of each system pipeline in the "working" position;
5. Check the link bolts of the transmission mechanism and fasten them well;
6. Check whether the clutch handle pressure is normal and whether the overspeed safety device is positioned;
7. Check whether the pressure of the gas cylinder is normal and whether the overspeed safety device is positioned;
8. Open the drain valve of the air pump;
9. Check whether the circulating water pump, oil pump and fuel pump are normal;
10. Set the excitation resistance to the maximum resistance position, and disconnect the power transmission switch.
Start and run operations:
1. For the unit that has been shut down for more than 24 hours, the test valve must be opened first, and the oil pump must be started. For units that have been shut down for more than 7 days, the insulation resistance of the exciter and operating circuit should be measured, which must meet the requirements;
2. Start the fuel pump, release the air in the pipeline, and observe whether the voltage is within the specified range. If it is normal, the official start-up can be carried out;
3. Check whether the voltage of the starting power supply meets the requirements. If the voltage is normal, press the start button and release it after the diesel engine runs normally;
4. After the diesel engine is running, observe the indicated value of the oil pressure gauge. When it rises above the specified value, stop the oil pump, close the drain valve of the scavenging pump, and thread the front clutch screw;
5. When the generator starts, it is considered that the generator and all electrical equipment are charged, and the human body should not touch the live parts;
6. After the generator is started, the speed of the diesel engine should be gradually increased, and the inspection before power transmission should be carried out;
7. Gradually adjust the speed of the diesel engine, but pay attention to observe whether the generator is running normally when adjusting. When normal, the brushes on the collector ring and the commutator should have no jumping, no sparks, and no abnormal noise;
8. Adjust the output voltage and frequency of the generator, the voltage value should be stable and reach 380v+-10v, and the frequency should reach 50Hz+-0.5Hz.
