Preparations before Diesel gen-set starting2022-09-12 14:52:18

Safety regulations of the generator operators
 
Generators

1. The operators should have their own duty, in the working clothes and insulant shoes.

2. Check the flywheel and railing cover of generator and keep them normal.

3. Start only after checking and ensure the gear-box, clutch, governor, oil level, and all fasteners in normal, and the temperature of oil not lower than 20℃

4. Set all the system pipeline valves on the positions of “on work”

5. Check and fasten the link bolt of transmit mechanism

6. Check the condition of clutch handle pressure, and the position of overspeed safety device

7. Check that pressure of air bottle, and the position of overspeed safety device

8. Open the blow-down valve of air pump

9. Check the condition of the circulating water pump, oil pump, and fuel pump

10. Turn the field resistance into the position of maximum resistance and turn off the power switch.

 
Operation of starting and running

1. Open the pilot operated valve and start oil pump first if the diesel gen-set downtime is more than 24 hours,

2. Measure the insulation resistance of exciter and operation circuit and keep it meet the requirement if the diesel gen-set downtime is more than 7 days

3. Start the fuel pump to release the air in the pipeline, and check the voltage in the specified range or not. Start only when it is normal

4. Check the condition of the voltage. If the voltage is normal, push the start button until the diesel generator runs

5. Observe the indicator values of oil pressure gauge after the diesel engine starting. Stop the oil pump and close the scavenging pump discharge valve, insert the front clutch screw, when it rises above the predetermined value.

6. Do not touch the live parts, after the generator starts, which means the generator and all electrical equipments have been charged

7. Increase the diesel engine speed gradually and check before electrification, after the generator starts.

8. Check the condition of the generator running when adjusting the diesel engine speed gradually. The normal condition of the electric brush and the commutator ring set should be no beating, no spark and no abnormal sound.
   Adjust the output voltage and frequency of generators. The voltage should be stable,  380v±10v and 50Hz±0.5Hz.
