Diesel generator set need to pay attention to multiple aspects in daily use to ensure their safe and stable operation. Here are some key precautions:
1、 Pre start inspection of diesel generator set
Oil level: Ensure that the oil level is within the specified range, and replenish it promptly if it is insufficient. Engine oil is crucial for lubricating diesel generators, as low or high oil levels can cause damage to the engine.
Water level of water tank: Check the water level of the cooling system to ensure sufficient water level. The cooling system is crucial for maintaining the normal operating temperature of the engine.
Fuel: Confirm that the fuel tank of the diesel generator set has sufficient diesel and ensure that the fuel pipeline is unobstructed. Poor quality fuel may cause problems such as engine carbon buildup and increased wear, so qualified fuel should be selected.
Battery: Check if the battery is fully charged and if the battery cable connection is secure. The battery is a key component for starting a diesel generator, and its performance directly affects the starting of the generator.
Exhaust system: Ensure that the exhaust system is unobstructed and unobstructed. The smoothness of the exhaust system is crucial for the engine's exhaust and heat dissipation.
2、 Start and Run
Startup steps: Turn the key switch to the "ON" position, and the indicator light on the dashboard should light up. Press the 'START' button to start the generator. If the startup is unsuccessful, wait for a few seconds and try again. The continuous startup should not exceed 3 times. After the generator is successfully started, immediately release the "START" button and observe whether the various indicators on the dashboard are normal.
Operation monitoring: During the operation of the generator, close attention should be paid to its operating parameters, such as voltage, current, frequency, oil pressure, cooling water temperature, etc. These parameters can reflect the operating status and performance of the equipment. Once abnormalities are detected, measures should be taken in a timely manner for handling.
Load adjustment: The load of the diesel generator should be controlled within a reasonable range to avoid overloading or light load operation. Overloading may cause equipment overheating and damage, while light loading may cause unstable equipment operation and affect power generation efficiency.
3、 Shutdown and maintenance of diesel generator set
Shutdown steps: Gradually reduce the load to put the generator in a light load state. Turn the key switch to the "OFF" position to shut down the generator. Turn off the battery switch and disconnect the battery cable connection.
Regular inspection and maintenance: Regular inspection and maintenance of diesel generators are key to ensuring their normal operation. This includes checking the levels of engine oil, coolant, fuel, etc., cleaning components such as radiators and air filters, and replacing severely worn parts. In addition, attention should be paid to safety issues such as whether the fasteners of the equipment are loose and whether the wires and cables are damaged.
Safety precautions: When using a diesel generator, necessary safety precautions should be taken, such as wearing protective goggles, gloves, and other personal protective equipment to avoid direct contact with high-temperature components or harmful gases. Meanwhile, ensure that there are no flammable or explosive materials around the equipment and maintain good ventilation.
4、 Other precautions for diesel generator sets
Running in period maintenance: New or overhauled diesel generators require running in. The purpose of running in is to make the mating surfaces smoother, with more reasonable clearances, and to prevent early wear. During the running in period, it should be operated without load for a period of time, and the speed and load should gradually change from low to high and from small to large.
Avoid sudden acceleration: Regardless of whether the car is cold or hot, it should be refueled smoothly and avoid continuous sudden acceleration. Rushing the accelerator can cause severe vibrations, increasing the friction between the mating surfaces and exacerbating the wear of the components.
Correct selection of fuel: The corresponding type of diesel should be selected according to the compression ratio and season of the diesel generator to reduce wear and corrosion of the components.
Emergency response measures: When using diesel generators, emergency response measures should be developed in advance to deal with possible emergencies. For example, when a device malfunctions or is abnormal, the power should be immediately cut off, the device should be stopped, and preliminary investigation and handling should be carried out. If the problem cannot be solved, professional maintenance personnel should be contacted in a timely manner for repair.
In summary, diesel generator sets need to pay attention to multiple aspects in daily use, including pre start inspection, start and operation monitoring, shutdown and maintenance, and other precautions. Only by fully understanding and mastering these key issues can we ensure the safe and stable operation of diesel generators.
