Ⅳ. Daily inspection content of emergency diesel generators
1. Environmental and visual inspection
Check whether the ventilation of the emergency diesel generator room is smooth, whether the lighting is sufficient, and there is no accumulation of debris around to ensure the safe operating environment of the equipment.
Check whether the emergency diesel generator shell is damaged or deformed, whether the coating is complete, whether the parts of the fuselage are not missing, and the nameplate information is clearly identifiable.
Confirm that the foundation of the emergency diesel generator is firmly fixed, there is no loosening or shifting, and there is no bumping or damage to each connecting pipeline.
2. Oil system inspection
Emergency diesel generator oil system: After stopping the machine and waiting for the oil to flow back, check whether the oil level is in the normal scale range, the color of the oil is normal, there is no blackening, emulsification or metal chips, and if necessary, add the same type of engine oil or replace the engine oil and filter.
Fuel system: check that the fuel tank of the emergency diesel generator has sufficient oil, the pipeline joint is free of oil seepage, the pipeline is not aging and cracked, and the pipeline air is manually drained to ensure smooth fuel supply; Check that the filter is not clogged and replace the filter element if necessary.
Cooling system: After the emergency diesel generator cools, check that the coolant level meets the requirements, without turbidity or sedimentation, and add the same type of coolant when it is insufficient; Clean the surface of the radiator from dust and debris to ensure good heat dissipation.
3. Core component inspection
Check that the air filter of the emergency diesel generator is clean and not damaged, and if there is a lot of dust, clean or replace it in time to ensure smooth air intake.
Check that the belt tension is appropriate, without cracks and wear, and ensure that the transmission is normal.
Check that the exhaust system of the emergency diesel generator is unblocked, the exhaust pipe and muffler are not damaged or blocked, and there is no abnormal black smoke discharge.
Listen to the uniform sound of the emergency diesel generator bearing, no abnormal noise, normal temperature, and no signs of overheating.
4. Electrical and control system inspection
Check that the emergency diesel generator battery is in good condition, the voltage is normal, the pile head is free of oxidation and corrosion, the connection is firm, and the charger is working normally.
Confirm that the generator grounding wire is firmly connected, free from loosening, rust, and the risk of leakage.
Check that the switches and buttons on the operation panel are functioning normally, the instrument display is clear and trouble-free, and the control switch is in the automatic standby position.
Check that the insulation performance of the stator and rotor winding of the emergency diesel generator is good, the terminal blocks are not loose or oxidized, and the conductive paste is polished and applied if necessary.
5. Monitoring of operating status
If the emergency diesel generator is in operation, inspect it every hour to monitor for abnormal sounds and vibrations, and whether there is any abnormal smell.
Observe that the operating parameters such as oil pressure, cooling water temperature, voltage, and frequency of the emergency diesel generator are stable within the normal range, and the smoke exhaust color is normal.
Check whether there is oil leakage or water leakage in the emergency diesel generator, and the pipeline joints are well sealed.
Regularly carry out no-load and on-load trial runs, and observe the smooth start-up, operation and shutdown process of emergency diesel generators, and there are no abnormalities in various parameters.
V. Q&A on Knowledge Related to Emergency Diesel Generators
1. How to determine the power of an emergency diesel generator?
Calculate the total power of all emergency loads, consider the inrush current when electric motors start, and generally select 1.2-1.5 times the total power.
2. How to maintain emergency diesel generators that are stored long-term?
Start and run for 15-30 minutes every month, regularly change the engine oil and filters, keep the battery charged, and store in a dry and ventilated environment.
3. Which key parameters need to be monitored during the operation of emergency diesel generators?
Pay attention to oil pressure, coolant temperature, output voltage, frequency, as well as smoke color and generator vibration.
